  • Does use of perioperative COX-2 inhibitors really increase risk of acute
           kidney injury'
    • Authors: Y. Y. Liu; F. S. Xue, H. X. Li

  • Protection against cold – a survey of available equipment in Swedish
           pre-hospital services
    • Authors: O. Henriksson; U. Björnstig, B.-I. Saveman, P. J. Lundgren
      Abstract: BackgroundThe aim of this study was to survey the current equipment used for prevention, treatment and monitoring of accidental hypothermia in Swedish pre-hospital services.MethodsA questionnaire was sent to all road ambulance services (AS), the helicopter emergency medical services (HEMS), the national helicopter search and rescue service (SAR) and the municipal rescue services (RS) in Sweden to determine the availability of insulation, active warming, fluid heating, and low-reading thermometers.ResultsThe response rate was 77% (n = 255). All units carried woollen or polyester blankets for basic insulation. Specific windproof insulation materials were common in the HEMS, SAR and RS units but only present in about half of the AS units. Active warming equipment was present in all the SAR units, but only in about two-thirds of the HEMS units and about one-third of the AS units. About half of the RS units had the ability to provide a heated tent or container. Low-reading thermometers were present in less than half of the AS and HEMS units and were non-existent in the SAR units. Pre-warmed intravenous fluids were carried by almost all of the AS units and half of the HEMS units but infusion heaters were absent in most units.ConclusionBasic insulation capabilities are well established in the Swedish pre-hospital services. Specific wind and waterproof insulation materials, active warming devices, low-reading thermometers and IV fluid heating systems are less common. We suggest the development and implementation of national guidelines on accidental hypothermia that include basic recommendations on equipment requirements.

  • Rapid response team patients triaged to remain on ward despite deranged
           vital signs: missed opportunities'
    • Authors: J. Tirkkonen; T. Kontula, S. Hoppu
      Abstract: BackgroundRapid response teams (RRTs) triage most patients to stay on ward, even though some of them have deranged vital signs according to RRTs themselves. We investigated the prevalence and outcome of this RRT patient cohort.MethodsA prospective observational study was conducted in a Finnish tertiary referral centre, Tampere University Hospital. Data on RRT activations were collected between 1 May 2012 and 30 April 2015. Vital signs of patients triaged to stay on ward without treatment limitations were classified according to objective RRT trigger criteria observed during the reviews.ResultsDuring the study period, 860 patients had their first RRT review and were triaged to stay on ward. Of these, 564 (66%) had deranged vital signs, while 296 (34%) did not. RRT patients with deranged vital signs were of comparable age and comorbidity index as stable patients. Even though the patients with deranged vital signs had received RRT interventions, such as fluids and medications, more often than the stable patients, they required new RRT reviews more often and had higher in-hospital and 30-day mortality. Moreover, the former group had substantially higher 1-year mortality than the latter (37% vs. 29%, P = 0.014). In a multivariate regression analysis, deranged vital signs during RRT review was found to be independently associated with 30-day mortality (OR 1.74; 95% CI 1.12–2.70).ConclusionPatients triaged to stay on ward despite deranged vital signs are high-risk patients who could benefit from routine follow-up by RRT nurses before they deteriorate beyond salvation.

  • Assessment of futility in out-of-hospital cardiac arrest
    • Authors: P. Setälä; S. Hoppu, I. Virkkunen, A. Yli-Hankala, A. Kämäräinen
      Abstract: BackgroundOur aim was to evaluate the impact of futile resuscitation attempts to the outcome calculations of attempted resuscitation in out-of-hospital cardiac arrest (OHCA). Defined as partial resuscitations, we focused on a subgroup of patients in whom cardiopulmonary resuscitation (CPR) was initiated, but further efforts were soon abandoned due to evidence of futility.MethodsWe conducted this study using the Utstein template during a 12-month study period. We compared the event characteristics between full and partial resuscitation attempts and determined the incidence, survival and neurological outcome.ResultsEmergency Medical Services (EMS) attended a total of 314 OHCA cases. In 34 cases, resuscitation was not attempted due to futility. Seventy-four cases were partial resuscitation attempts where resuscitation was soon discontinued due to dismal prognostic factors. Partial attempts were associated with an unwitnessed OHCA, prolonged downtime, end-stage malignant disease, multiple trauma, asystole or pulseless electrical activity as the initial rhythm, and a first responding unit being the first unit on the scene (P

  • Return of spontaneous circulation and long-term survival according to
           feedback provided by automated external defibrillators
    • Authors: M. Agerskov; M. B. Hansen, A. M. Nielsen, T. P. Møller, M. Wissenberg, L. S. Rasmussen
      Abstract: BackgroundWe aimed to investigate the effect of automated external defibrillator (AED) feedback mechanisms on survival in out-of-hospital cardiac arrest (OHCA) victims. In addition, we investigated converting rates in patients with shockable rhythms according to AED shock waveforms and energy levels.MethodsWe collected data on OHCA occurring between 2011 and 2014 in the Capital Region of Denmark where an AED was applied prior to ambulance arrival. Patient data were obtained from the Danish Cardiac Arrest Registry and medical records. AED data were retrieved from the Emergency Medical Dispatch Centre (EMDC) and information on feedback mechanisms, energy waveform and energy level was downloaded from the applied AEDs.ResultsA total of 196 OHCAs had an AED applied prior to ambulance arrival; 62 of these (32%) provided audio visual (AV) feedback while no feedback was provided in 134 (68%). We found no difference in return of spontaneous circulation (ROSC) at hospital arrival according to AV-feedback; 34 (55%, 95% confidence interval (CI) [13–67]) vs. 72 (54%, 95% CI [45–62]), P = 1 (odds ratio (OR) 1.1, 95% CI [0.6–1.9]) or 30-day survival; 24 (39%, 95% CI [28–51]) vs. 53 (40%, 95% CI [32–49]), P = 0.88 (OR 1.1 (95% CI [0.6–2.0])). Moreover, we found no difference in converting rates among patients with initial shockable rhythm receiving one or more shocks according to AED energy waveform and energy level.ConclusionsNo difference in survival after OHCA according to AED feedback mechanisms, nor any difference in converting rates according to AED waveform or energy levels was detected.

  • Effects of red blood cell storage time on transfused patients in the
           ICU—protocol for a systematic review
    • Authors: S. L. Rygård; A. B. Jonsson, M. B. Madsen, A. Perner, L. B. Holst, P. I. Johansson, J. Wetterslev
      Abstract: BackgroundPatients in the intensive care unit (ICU) are often anaemic due to blood loss, impaired red blood cell (RBC) production and increased RBC destruction. In some studies, more than half of the patients were treated with RBC transfusion. During storage, the RBC and the storage medium undergo changes, which lead to impaired transportation and delivery of oxygen and may also promote an inflammatory response. Divergent results on the clinical consequences of storage have been reported in both observational studies and randomised trials. Therefore, we aim to gather and review the present evidence to assess the effects of shorter vs. longer storage time of transfused RBCs for ICU patients.MethodsWe will conduct a systematic review with meta-analyses and trial sequential analyses of randomised clinical trials, and also include results of severe adverse events from large observational studies. Participants will be adult patients admitted to an ICU and treated with shorter vs. longer stored RBC units. We will systematically search the Cochrane Library, MEDLINE, Embase, BIOSIS, CINAHL and Science Citation Index for relevant literature, and we will follow the recommendation by the Cochrane Collaboration and the Preferred Reporting Items for Systemtic Review and Meta-Analysis (PRISMA)-statement. We will assess the risk of bias and random errors, and we will use the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to evaluate the overall quality of evidence.ConclusionWe need a high-quality systematic review to summarise the clinical consequences of RBC storage time among ICU patients.

  • The impact of fatigue on the non-technical skills performance of critical
           care air ambulance clinicians
    • Authors: J. A. Myers; D. M. C. Powell, S. Aldington, D. Sim, A. Psirides, K. Hathaway, M. F. Haney
      Abstract: BackgroundThe relationship between fatigue-related risk and impaired clinical performance is not entirely clear. Non-technical factors represent an important component of clinical performance and may be sensitive to the effects of fatigue. The hypothesis was that the sum score of overall non-technical performance is degraded by fatigue.MethodsNineteen physicians undertook two different simulated air ambulance missions, once when rested, and once when fatigued (randomised crossover design). Trained assessors blinded to participants’ fatigue status performed detailed structured assessments based on expected behaviours in four non-technical skills domains: teamwork, situational awareness, task management, and decision making. Participants also provided self-ratings of their performance. The primary endpoint was the sum score of overall non-technical performance.ResultsThe main finding, the overall non-technical skills performance rating of the clinicians, was better in rested than fatigued states (mean difference with 95% CI, 2.8 [2.2–3.4]). The findings remained consistent across individual non-technical skills domains; also when controlling for an order effect and examining the impact of a number of possible covariates. There was no difference in self-ratings of clinical performance between rested and fatigued states.ConclusionNon-technical performance of critical care air transfer clinicians is degraded when they are fatigued. Fatigued clinicians may fail to recognise the degree to which their performance is compromised. These findings represent risk to clinical care quality and patient safety in the dynamic and isolated environment of air ambulance transfer.

  • Assessment of plasma endostatin to predict acute kidney injury in

    • Authors: J. Mårtensson; S. T. Vaara, V. Pettilä, T. Ala-Kokko, S. Karlsson, O. Inkinen, A. Uusaro, A. Larsson, M. Bell
      Abstract: BackgroundWe evaluated whether plasma endostatin predicts acute kidney injury (AKI), need for renal replacement therapy (RRT), or death.MethodsProspective, observational, multicenter study from 1 September 2011 to 1 February 2012 with data from 17 intensive care units (ICUs) in Finland.ResultsA total of 1112 patients were analyzed. We measured plasma endostatin within 2 h of ICU admission. Early AKI (KDIGO stage within 12 h of ICU admission) was found in 20% of the cohort, and 18% developed late AKI (KDIGO criteria> 12 h from ICU admission). Median (IQR) admission endostatin was higher in the early AKI group, 29 (19.1, 41.9) ng/ml as compared to 22.4 (16.1, 30.1) ng/ml for the late AKI group, and 18 (14.0, 23.6) ng/ml for non-AKI patients (P < 0.001). Endostatin level increased with increasing KDIGO stage. Significantly higher endostatin levels were found in patients with sepsis as compared to those without. Predictive properties for AKI, RRT, and mortality were low with corresponding areas under the receiver operating characteristic curve (AUC) of 0.62, 0.67, and 0.59. Sensitivity analyses among patients with chronic kidney disease or sepsis did not improve the predictive ability of endostatin. Adding endostatin to a clinical AKI prediction model (illness severity score, urine output, and age) insignificantly changed the AUC from 0.67 to 0.70 (P = 0.14).ConclusionsEndostatin increases with AKI severity but has limited value as a predictor of AKI, RRT and 90-day mortality in patients admitted to ICU. Moreover, endostatin does not improve AKI risk prediction when added to a clinical risk model.

  • Pregabalin reduces opioid consumption and hyperalgesia but not pain
           intensity after laparoscopic donor nephrectomy
    • Authors: M. Myhre; L. Romundstad, A. Stubhaug
      Abstract: BackgroundGabapentinoids are increasingly used to reduce acute postoperative pain, opioid consumption and opioid-related adverse effects. We explored the opioid-sparing, analgesic and anti-hyperalgesic effect of perioperative administered pregabalin in laparoscopic living donor nephrectomy.MethodsIn this randomized controlled trial, 80 patients were recruited and randomized to receive pregabalin 150 mg twice daily or placebo on the day of surgery and the first postoperative day as part of a multimodal analgesic regimen. Primary outcome was opioid consumption 0–48 h after surgery. Secondary outcomes were pain intensity at rest and with movement 0–48 h after surgery using the 0–10 Numeric Rating Scale and incisional hyperalgesia measured 24 h post-surgery and at hospital discharge. Further secondary outcomes were adverse effects. Persistent post-surgical pain was registered 6 weeks, 6 and 12 months after surgery.ResultsPregabalin significantly reduced opioid consumption compared with placebo 0–48 h after surgery (median mg [25th, 75th percentile]); 29.0 (22.0–45.5) vs. 41.8 (25.8–63.6) (P = 0.04). Pain intensity 0–48 h after surgery calculated as area under the pain (NRS) vs. time curve was not statistically different between groups at rest (P = 0.12) or with movement (P = 0.21). Pregabalin decreased incisional hyperalgesia 24 h after surgery (median cm [25th, 75th percentile] 8.5 (1.0–18.5) vs. 15.5 (9.5–24.0) (P = 0.02). Nausea (P ≤ 0.01), use of antiemetics (P ≤ 0.01) and pain-related sleep interference (P = 0.02) were reduced with pregabalin.ConclusionsPerioperative pregabalin added to a multimodal analgesic regimen was opioid-sparing, but made no difference to pain intensity score 0–48 h after surgery. Pregabalin may reduce incisional hyperalgesia on the first day after surgery.

  • Impact of systemic inflammatory response syndrome and surgical Apgar score
           on post-operative acute kidney injury
    • Authors: Y. Toyonaga; K. Asayama, Y. Maehara
      Abstract: BackgroundSurgical Apgar Score (SAS) is relatively weakly associated with post-operative outcomes in emergency surgery, compared with elective surgery. A combination of systemic inflammatory response syndrome (SIRS) and SAS may be useful for prediction of poor outcomes after emergency surgery.MethodsA retrospective study was conducted in patients who underwent emergency abdominal or cerebral surgery from January 2005 to December 2010. AKI was diagnosed using Acute Kidney Injury Network criteria for 2 days after surgery. Pre-operative SIRS was defined as SIRS score ≥ 2. Patients were divided into those with SAS ≥ 5 and < 5. Independent risk factors for post-operative AKI were identified. Ability to predict post-operative AKI was determined using receiver operating characteristic (ROC) curve analysis.ResultsOf 742 patients, 175 (24%) had post-operative AKI. Pre-operative SIRS (OR 1.9, 95% CI: 1.2–2.9, P < 0.01) and SAS < 5 (OR 2.6, 95% CI: 1.7–4.1, P < 0.01) were independent risk factors for post-operative AKI. Patients without SIRS and SAS < 5 had an increased risk of post-operative AKI (odds ratio (OR) 3.6, 95% confidence interval (CI) 1.9–6.7, P < 0.01) and those with SIRS and SAS < 5 had increased risks of post-operative AKI (OR 5.9, 95% CI: 3.7–9.3, P < 0.01) and hospital mortality (OR 3.5, 95% CI: 1.9–6.3, P < 0.01). In ROC analysis, the c-statistic using both SIRS and SAS < 5 was 0.81 (95% CI: 0.77–0.84, P < 0.01) and higher than without use of these factors (P < 0.01).ConclusionPre-operative SIRS and SAS are independently associated with post-operative AKI. Simultaneous use of pre-operative SIRS and SAS may improve prediction of poor post-operative outcomes.

  • Development of an instrument for the evaluation of advanced life support
    • Authors: L.-M. Peltonen; V. Peltonen, S. Salanterä, M. Tommila
      Abstract: BackgroundAssessing advanced life support (ALS) competence requires validated instruments. Existing instruments include aspects of technical skills (TS), non-technical skills (NTS) or both, but one instrument for detailed assessment that suits all resuscitation situations is lacking. This study aimed to develop an instrument for the evaluation of the overall ALS performance of the whole team.MethodsThis instrument development study had four phases. First, we reviewed literature and resuscitation guidelines to explore items to include in the instrument. Thereafter, we interviewed resuscitation team professionals (n = 66), using the critical incident technique, to determine possible additional aspects associated with the performance of ALS. Second, we developed an instrument based on the findings. Third, we used an expert panel (n = 20) to assess the validity of the developed instrument. Finally, we revised the instrument based on the experts’ comments and tested it with six experts who evaluated 22 video recorded resuscitations.ResultsThe final version of the developed instrument had 69 items divided into adherence to guidelines (28 items), clinical decision-making (5 items), workload management (12 items), team behaviour (8 items), information management (6 items), patient integrity and consideration of laymen (4 items) and work routines (6 items). The Cronbach's α values were good, and strong correlations between the overall performance and the instrument were observed.ConclusionThe instrument may be useful for detailed assessment of the team's overall performance, but the numerous items make the use demanding. The instrument is still under development, and more research is needed to determine its psychometric properties.

  • End-tidal control vs. manually controlled minimal-flow anesthesia: a
           prospective comparative trial
    • Authors: A. J. Wetz; M. M. Mueller, K. Walliser, C. Foest, S. Wand, I. F. Brandes, R. M. Waeschle, M. Bauer
      Abstract: BackgroundTo ensure safe general anesthesia, manually controlled anesthesia requires constant monitoring and numerous manual adjustments of the gas dosage, especially for low- and minimal-flow anesthesia. Oxygen flow-rate and administration of volatile anesthetics can also be controlled automatically by anesthesia machines using the end-tidal control technique, which ensures constant end-tidal concentrations of oxygen and anesthetic gas via feedback and continuous adjustment mechanisms. We investigated the hypothesis that end-tidal control is superior to manually controlled minimal-flow anesthesia (0.5 l/min).MethodsIn this prospective trial, we included 64 patients undergoing elective surgery under general anesthesia. We analyzed the precision of maintenance of the sevoflurane concentration (1.2–1.4%) and expiratory oxygen (35–40%) and the number of necessary adjustments.ResultsTarget-concentrations of sevoflurane and oxygen were maintained at more stable levels with the use of end-tidal control (during the first 15 min 28% vs. 51% and from 15 to 60 min 1% vs. 19% deviation from sevoflurane target, P < 0.0001; 45% vs. 86% and 5% vs. 15% deviation from O2 target, P < 0.01, respectively), while manual controlled minimal-flow anesthesia required more interventions to maintain the defined target ranges of sevoflurane (8, IQR 6–12) and end-tidal oxygen (5, IQR 3–6). The target-concentrations were reached earlier with the use of end-tidal compared with manual controlled minimal-flow anesthesia but required slightly greater use of anesthetic agents (6.9 vs. 6.0 ml/h).ConclusionsEnd-tidal control is a superior technique for setting and maintaining oxygen and anesthetic gas concentrations in a stable and rapid manner compared with manual control. Consequently, end-tidal control can effectively support the anesthetist.

  • Ultrasound-guided regional blockade for lipoma excision: a new approach to
           an old technique
    • Authors: T. F. Tammam; G. A. Kamhawy
      Abstract: BackgroundLocal anesthesia for lipoma excision can be feasible with anesthetic injection in the fascial plane between the lipoma and the surrounding soft tissues under real-time ultrasonography [ultrasound- guided lipoma plane (ULP) block]. The advantage of targeting a single anesthetic injection plane under ultrasound guidance may allow for technically easier block placement and long-term analgesic effects.MethodsForty-eight patients were randomly assigned to receive ULP block, group A (n = 24) or traditional block, group B (n = 24). Primary outcome measure was the number of needle passes required to perform the blockade. The level of procedure pain and the time to first request of analgesia were assessed.ResultsMedian (interquartile range) needle passes required to complete the blockade was significantly less in the group A 1(1, 1) in comparison with the group B 3 (2.5, 3); P = 0.0001. Group A required fewer needle redirections 1.5 (1, 2) than group B 2 (2, 2.5); P = 0.001. Group A showed significantly less procedure-related pain 2 (2, 3) when compared with group B 4 (3, 4); P = 0.0001. The time to first rescue analgesic was significantly longer in group A (21.3 ± 4.7 h) in comparison with group B (4.4 ± 1.2 h); P = 0.001.ConclusionUltrasound-guided lipoma plane blockade reduces the number of needle passes required to complete the block and provides less procedure pain and longer pain relief compared with the traditional block in patients undergoing lipoma excision.

      Abstract: BackgroundIn pregnancy, the major causes of morbidity and mortality include diseases that affect circulation profoundly and restoration of normal circulation is a key objective. Focused cardiac ultrasound provides information on the individual determinants of circulation and has a significant impact on patient management. This study aimed to determine the feasibility of focused cardiac ultrasound in term parturients.MethodsForty parturients underwent focused cardiac ultrasound. Parasternal long-axis, parasternal short-axis, 4-chamber and subcostal views were performed in the left-lateral position and the supine position by a novice operator. All images were graded on the following scale: 1 = no image; 2 = poor and insufficient image; 3 = sufficient image quality; 4 = good image quality; 5 = perfect image quality. A cut-off grade of three signified images sufficient for clinical decision-making.ResultsImages sufficient for clinical decision-making were obtained in all patients when including all imaging views. 37/40 (93 %) patients presented images of grade ≥ 4, whereas 10/40 (25%) patients had images of grade 5. Image grades were higher in the left lateral position (all P < 0.001). Parturients with a body mass index ≤ 30 kg/m2 did not present different image grades than parturients with a higher body mass index (P = 0.753). Subcostal views could not be obtained.ConclusionFocused cardiac ultrasound is feasible in the obstetric population and images of sufficient quality for clinical decision-making were obtained in all parturients by an operator with limited experience.

      Abstract: BackgroundAcute fire smoke inhalation injury involves inflammatory mediators whose roles are poorly understood. We carried out a prospective observational study of fire smoke victims to identify clinical and biochemical markers that may predict pulmonary dysfunction and investigated possible correlations between dysfunction and cytokines in bronchoalveolar lavage (BAL) fluid and blood.MethodsForty patients with respiratory and/or neurological symptoms following acute fire smoke inhalation had pulmonary function tests and blood gas analyses performed on admission, at discharge, and after 3 months. Cytokines were measured using BioPlex/XMap technology.ResultsOn admission, 30 (75%) patients had dyspnea. Patients presenting with bronchial wheezing (n = 14) had significantly lower PEF (201 l/min, 82–360) than non-wheezing patients (406 l/min, 100–683) (n = 16, P = 0.03). Bronchial wheezing predicted need for ICU treatment with OR = 93.3 at 95% CI (P < 0.001) and was associated with gas exchange impairment, with mean paO2/FiO2 ratio 34.4 (11.8–49.8) kPa on admission and 21.3 (8.3–44.5) kPa 48 h later. Blood HbCO also predicted ICU treatment, with OR = 1.58 at 95% CI (P < 0.001). Serum CRP, IL-6, IL-8, and MCP-1 were significantly higher in wheezing patients after 12–24 h compared with non-wheezing patients and study controls. Cytokine levels were still elevated after 3 months. BAL fluid had significantly higher levels of IL-8, MCP-1, IL-1β, and G-CSF compared with healthy controls.ConclusionIn victims of fire smoke inhalation, pulmonary wheezing predicts inflammation, pulmonary dysfunction, respiratory failure, and need for intensive care.

    • Authors: Z. Zhao; S.-Y. Peng, M.-Y. Chang, Y.-L. Hsu, I. Frerichs, H.-T. Chang, K. Möller
      Abstract: BackgroundThe study objective was to examine the correlation between regional ventilation distribution measured with electrical impedance tomography (EIT) and weaning outcomes during spontaneous breathing trial (SBT).MethodsFifteen patients received 100% automatic tube compensation (ATC) during the first and 70% during the second hour. Another 15 patients received external continuous positive airway pressure (CPAP) of 5 and 7.5 cmH2O during the first and second hours, respectively. Regional ventilation distributions were monitored with EIT.ResultsTidal volume and tidal variation of impedance correlated significantly during assist-control ventilation and ATC in all patients (r2 = 0.80 ± 0.18, P < 0.001). Higher support levels resulted in similar ventilation distribution and tidal volume, but higher end-expiratory lung impedance (EELI) (P < 0.05). Analysis of regional intratidal gas distribution revealed a redistribution of ventilation towards dorsal regions with lower support level in 13 of 30 patients. These patients had a higher weaning success rate (only 1 of 13 patients failed). Eight of 17 other patient failed (P < 0.05). The number of SBT days needed for weaning was significantly lower in the former group of 13 patients (13.1 ± 4.0 vs. 20.9 ± 11.2 days, P < 0.05).ConclusionsRegional ventilation distribution patterns during inspiration were associated with weaning outcomes, and they may be used to predict the success of extubation.

  • First-aid training in school: amount, content and hindrances
    • Authors: H. K. Bakke; H. K. Bakke, R. Schwebs
      Abstract: BackgroundTo increase knowledge and competence about first aid in the population, first-aid instruction is included in primary and secondary school curricula. This study aimed to establish how much time is spent on first-aid training, which first-aid measures are taught, and which factors prevent teachers from providing the quantity and quality of first-aid training that they wish to give.MethodsA questionnaire was distributed to teachers in physical education in primary and secondary schools and to teachers in vocational subjects in higher secondary schools.ResultsThe teachers taught a median of two lessons in first aid per year. Cardiopulmonary resuscitation (CPR) was taught by 64% of teachers, free airway and recovery position by 69% and stopping severe bleeding by 51%. Recognising heart attack and stroke was taught by 25% and 23%, respectively. The main factors that the teachers perceived as limiting the amount and quality of first-aid training were insufficient learning objective specifications in the curriculum, too many other competence aims, lack of CPR mannequins and lack of training as first-aid instructors.DiscussionNorwegian teachers provide an appreciable amount of first-aid training to their students. However, several potential life-saving measures are poorly covered. The curriculum needs to contain first aid but also should specify what first-aid measures to be taught. First-aid training of teachers should adequately prepare them to be first-aid instructors.

      Abstract: BackgroundIntensive care for comatose survivors of cardiac arrest includes targeted temperature management (TTM) to attenuate cerebral reperfusion injury. A recent multi-center clinical trial did not show any difference in mortality or neurological outcome between TTM targeting 33°C or 36°C after out-of-hospital-cardiac-arrest (OHCA). In our institution, the TTM target was changed accordingly from 34 to 36°C. The aim of this retrospective study was to analyze if this change had affected patient outcome.MethodsIntensive care registry and medical record data from 79 adult patients treated for OHCA with TTM during 2010 (n = 38; 34°C) and 2014 (n = 41; 36°C) were analyzed for mortality and neurological outcome were assessed as cerebral performance category. Student's t-test was used for continuous data and Fischer's exact test for categorical data, and multivariable logistic regression was applied to detect influence from patient factors differing between the groups.ResultsWitnessed arrest was more common in 2010 (95%) vs. 2014 (76%) (P = 0.03) and coronary angiography was more common in 2014 (95%) vs. 2010 (76%) (P = 0.02). The number of patients awakening later than 72 h after the arrest did not differ. After adjusting for gender, hypertension, and witnessed arrest, neither 1-year mortality (P = 0.77), nor 1-year good neurological outcome (P = 0.85) differed between the groups.ConclusionOur results, showing no difference between TTM at 34°C and TTM at 36°C as to mortality or neurological outcome after OHCA, are in line with the previous TTM-trial results, supporting the use of either target temperature in our institution.

  • Load-dependence of myocardial deformation variables – a clinical
           strain-echocardiographic study
    • Authors: M. Fredholm; K. Jörgensen, E. Houltz, S.-E. Ricksten
      Abstract: BackgroundThe effects of left ventricular (LV) loading on myocardial deformation variables are not well-studied in the clinical setting. In the present study, we evaluated the effects of isolated changes in preload, afterload and heart rate on LV longitudinal strain, systolic (SR-S) and early diastolic strain rate (SR-E) in post-cardiac surgery patients.MethodsTwenty-one patients were studied early after cardiac surgery. Longitudinal myocardial strain and SR were analysed off-line using 2-D speckle echocardiography. The experimental protocol consisted of three consecutive interventions: (1) preload was increased by passive leg elevation, (2) afterload was increased by an infusion of phenylephrine to increase arterial blood pressure by 10–15% and (3) heart rate was increased 10% and 20% by atrial pacing. During both the preload and afterload challenges heart rate was kept constant by atrial pacing. Central venous pressure was kept constant during pacing by infusion of hetastarch/albumin.ResultsThe increase in preload increased LV strain, SR-S and SR-E by 20%, 11% and 17%, respectively. The phenylephrine-induced increase in afterload, did not affect LV strain, SR-S or SR-E. LV strain was not affected while SR-S and SR-E increased by pacing-induced heart rate increase.ConclusionAfter cardiac surgery, systolic and early diastolic strain rate are dependent on both preload and heart rate, while neither of these variables was afterload-dependent. LV strain was preload-dependent but not affected by atrial pacing. When evaluating the direct effects of various pharmacological or other interventions on myocardial contractility and relaxation, preload and heart rate must be controlled.

  • High frequency jet ventilation for motion management during ablation
           procedures, a narrative review
    • Authors: K. Galmén; P. Harbut, J. Freedman, J. G. Jakobsson
      Abstract: BackgroundHigh frequency jet ventilation (HFJV) is a method of ventilation that has gained renewed interest over the recent years as it can reduce organ movement to near static conditions, thus enhancing surgical precision in minimal invasive procedures, for example, ablation procedures for atrial fibrillation and solid organ tumours. The aim of this review was to create a summary of the current evidence concerning the clinical use of HFJV for ablative procedures.MethodPubMed was searched for the key words high frequency ventilation and ablation January 1990–December 2016.ResultThe search initially identified 34 papers, 14 met the inclusion criteria. Articles in other languages than English (n = 1), comments regarding other articles (n = 4) and articles that did not include HFJV or ablative procedures (n = 15) were excluded. Two articles were added from references in papers included from the primary search. Sixteen studies were finally included in the review; four updates/reviews and 12 papers with results from studies of HFJV on humans, with a total of 889 patients; 498 patients ventilated with HFJV and 391 controls. There were no randomised studies. The overall scientific quality of the studies was low.ConclusionThere is a lack of well-designed studies evaluating HFJV during ablation procedures. The available information, while sparse, supports the effect of less tissue movement, resulting in better surgical precision and outcome; such as shorter procedural time, fewer shock waves (ESWL) and less recurrence of atrial fibrillation. Randomised controlled studies are needed in this promising area of research to prove its superiority to standard ventilation.

  • The incidence and characteristics of 3-month mortality after
           intraoperative cardiac arrest in adults
    • Authors: M. Hur; H.-C. Lee, K. H. Lee, J.-T. Kim, C.-W. Jung, H.-P. Park
      Abstract: BackgroundThere is little information about clinical outcomes after intraoperative cardiac arrest (IOCA). We determined the incidence and characteristics of 3-month mortality after IOCA.MethodsThe electronic medical records of 238,648 adult surgical patients from January 2005 to December 2014 were reviewed retrospectively. Characteristics of IOCA were documented using the Utstein reporting template.ResultsIOCA occurred in 50 patients (21/100,000 surgeries). Nineteen patients died in the operating room, and further 12 patients died within 3 months post-arrest (total mortality: 62%). Three survivors at 3 months post-arrest had unfavourable neurological outcome. Finally, 34 patients showed unfavourable clinical outcomes at 3 months post-arrest. The incidences of non-cardiac surgery, emergency, pre-operative intubation state, non-shockable initial cardiac rhythm, hypovolaemic shock, pre-operative complications-induced cardiac arrest, non-anaesthetic cause of cardiac arrest, intra- and post-arrest transfusion, and continuous infusion of inotrope or vasopressor in intensive care unit (ICU) were significantly higher in non-survivors at 3 months post-arrest. Total epinephrine dose administrated during arrest was higher, and the duration of cardiac compressions was longer in non-survivors at 3 months post-arrest.ConclusionsIn this study, the incidence of IOCA was 21/100,000 surgeries and the 3-month mortality rate after IOCA was 62%. Several factors including surgical emergency, non-shockable initial cardiac rhythm, pre-operative complications, surgical complications, long duration of cardiac compressions, high total epinephrine dose, transfusion, and continuous infusion of inotropes or vasopressors in ICU seemed to be risk factors for 3-month mortality after IOCA. These risk factors should be considered in the light of relatively small sample size of this study.

  • Comparison of a paediatric emergency ruler with a digital algorithm for
           weight and age estimation
    • Authors: Ch. Both; A. Schmitz, P. K. Buehler, J. Wittwer, M. Weiss, A. R. Schmidt
      Abstract: BackgroundEmergency tapes like the “Paediatric-Emergency-Ruler” (PaedER) provide drug dosing and recommend medical airway equipment based on estimated patient bodyweight and age. Previous studies have revealed unsatisfactory accuracy in bodyweight estimation, due to the tapes′ length-based weight categories. Therefore, we developed a digital algorithm allowing continuous length-based estimation of weight and age. The aim of this study was to compare the new algorithm with the PaedER regarding accuracy in estimating bodyweight and recommendation of medical airway equipment.MethodsPatients with a body length suitable for the PaedER were included in this single centre, prospective clinical observation trial after obtaining informed written parental consent. Bodyweight estimations by the algorithm and PaedER within ± 10% and ± 20% of the actual bodyweight were compared. Furthermore, medical airway equipment suggested by the PaedER and algorithm were compared with the equipment actually used for anaesthesia. Wilcoxon- and McNemar-Tests were used for statistical analysis. Results are median (interquartiles), P

  • A novel combination of peripheral nerve blocks for arthroscopic shoulder
    • Authors: D. Musso; S. Flohr-Madsen, K. Meknas, T. Wilsgaard, L. M. Ytrebø, Ø. Klaastad
      Abstract: BackgroundInterscalene brachial plexus block is currently the gold standard for intra- and post-operative pain management for patients undergoing arthroscopic shoulder surgery. However, it is associated with block related complications, of which effect on the phrenic nerve have been of most interest. Side effects caused by general anesthesia, when this is required, are also a concern. We hypothesized that the combination of superficial cervical plexus block, suprascapular nerve block, and infraclavicular brachial plexus block would provide a good alternative to interscalene block and general anesthesia.MethodsTwenty adult patients scheduled for arthroscopic shoulder surgery received a combination of superficial cervical plexus block (5 ml ropivacaine 0.5%), suprascapular nerve block (4 ml ropivacaine 0.5%), and lateral sagittal infraclavicular block (31 ml ropivacaine 0.75%). The primary aim was to find the proportion of patients who could be operated under light propofol sedation, without the need for opioids or artificial airway. Secondary aims were patients' satisfaction and surgeons' judgment of the operating conditions.ResultsNineteen of twenty patients (95% CI: 85–100) underwent arthroscopic shoulder surgery with light propofol sedation, but without opioids or artificial airway. The excluded patient was not comfortable in the beach chair position and therefore received general anesthesia. All patients were satisfied with the treatment on follow-up interviews. The surgeons rated the operating conditions as good for all patients.ConclusionThe novel combination of a superficial cervical plexus block, a suprascapular nerve block, and an infraclavicular nerve block provides an alternative anesthetic modality for arthroscopic shoulder surgery.

  • Serial perioperative cell-free DNA levels in donors and recipients
           undergoing living donor liver transplantation
    • Authors: K. Prakash; S. Aggarwal, S. Bhardwaj, G. Ramakrishna, C. K. Pandey
      Abstract: BackgroundEffect of anaesthesia and surgery on cell-free DNA (cfDNA) is not known. Given that surgical stress augments inflammation and injury, we hypothesized that levels of cfDNA will fluctuate during perioperative period. Therefore, in this study serial perioperative cfDNA concentration was measured in donors and recipients undergoing living donor liver transplantation (LDLT).MethodsBaseline, post-induction, intraoperative and post-operative plasma cfDNA levels were evaluated in 21 donors and recipients each, by Sytox green method. In addition, qPCR was performed in a subset of samples.ResultsBaseline cfDNA levels were higher in recipients (37.62 ng/ml) than in donors (25.49 ng/ml). A decrease in cfDNA was observed following anaesthesia induction in both recipients (11.90 ng/ml) and donors (10.75 ng/ml). When the kinetics of the cfDNA was monitored further, an increase was noted intraoperatively in donors (46.18 ng/ml) and recipients (anhepatic phase: 56.25 ng/ml, reperfusion phase: 54.36 ng/ml). cfDNA levels remained high post-operatively. One recipient who developed post-operative sepsis had the highest cfDNA level (94.72 ng/ml).ConclusionPlasma cfDNA levels are high in recipients indicative of liver injury. Lower cfDNA levels following induction may be attributed to the subduing effect of anaesthetic agents on cell death. High cfDNA levels seen in intra- and post-operative phases reflect cellular trauma and inflammation. This similar pattern of fluctuation of cfDNA level in donors and recipients is suggestive of its possible utility as a surgical stress marker. In addition, comparable cfDNA levels in anhepatic and reperfusion phase reflect less ischemia reperfusion injury during LDLT.

  • Risk factors for peripheral nerve injuries following neuraxial labour
           analgesia: a nested case–control study
    • Authors: G. Haller; I. Pichon, F.-O. Gay, G. Savoldelli
      Abstract: BackgroundPost-partum lower extremity motor and sensory dysfunctions occur in 0.1–9.2‰ of deliveries. While macrosomia, lithotomy position and forceps use are well-identified causes of peripheral nerve injuries, additional contributors such as patient condition and anaesthesia care may also have to be considered.MethodsWe performed a case–control study nested in a cohort of 19,840 patients having neuraxial anaesthesia for childbirth. Cases were all patients who developed motor or sensory dysfunction of lower extremities in the post-partum period. These were compared, using Chi-square, Fisher's exact test, logistic regression and time series, to a random sample of controls without any neurological symptoms or injury.ResultsWe identified 19 (0.96‰) patients with peripheral nerve injuries of which 15 (0.76‰) were likely associated with obstetrical care. In four additional cases (0.20‰), a nerve root injury due to the Tuohy needle was suspected. Univariate risk factors were: a gestational age ≥ 41 weeks, Odds Ratio (OR) 3.8; 95% CI: 1.1–13.1, late initiation of neuraxial anaesthesia OR 8.2; 95% CI: 1.8–37.9, a repeated anaesthetic procedure OR 2.8; 95% CI: 1.0–7.8, assisted delivery with forceps OR 9.8; 95% CI: 1.2–114.1 and newborn birth weight> 3.5 kg with an OR 6.8; 95% CI: 2.0–22.5.ConclusionObstetrical related factors are the most prominent risk associated with peripheral nerve injuries. This study highlights however that patient and anaesthesia-related factors may also contribute to peripheral nerve injuries.

    • Authors: L. Lannemyr; E. Lundin, B. Reinsfelt, G. Bragadottir, B. Redfors, J. Oras, S.-E. Ricksten
      Abstract: BackgroundAcute kidney injury (AKI) is a common complication with a major impact on morbidity and mortality after cardiac surgery with cardiopulmonary bypass (CPB). The aim of the present study was to perform a detailed analysis on the release of the tubular injury biomarker N-acetyl-b-D-glucosaminidase (NAG) during and early after CPB and to describe independent predictors of maximal tubular injury. We hypothesized that renal tubular injury occurs early after the onset of CPB.MethodsIn this prospective observational study, we included 61 patients undergoing open cardiac surgery with an expected CPB duration exceeding 60 min. The urinary NAG levels were measured at 30 min intervals during CPB, as well as early (30 min) after CPB and post-operatively. Independent predictors of tubular injury were identified using an Interquantile multivariate regression model.ResultsAlready 30 min after the onset of CPB, NAG excretion was significantly increased (P

  • Influence of lateral position and pneumoperitoneum on oropharyngeal leak
           pressure with two types of laryngeal mask airways
    • Authors: S. Lan; Y. Zhou, J. T. Li, Z. Z. Zhao, Y. Liu
      Abstract: BackgroundAn important parameter to monitor adequate ventilation for laryngeal mask airway (LMA) is its oropharyngeal leak pressure (OLP). This study was designed to evaluate and compare the effect of lateral position and pneumoperitoneum on the OLP and ventilation efficiency between LMA™ Proseal (PLMA) and LMA™ Supreme (SLMA).MethodsPatients were randomized to receive either the PLMA or the SMLA. The OLP was assessed in both the supine position and the lateral position with or without pneumoperitoneum. Minute ventilation was increased to maintain normal EtCO2 as far as possible. Ventilatory efficiency was scored as Class I (optimal, EtCO2 35–45 mmHg), Class II (suboptimal, EtCO2 45–55 mmHg) and Class III (poor, EtCO2>55 mmHg). Adverse events associated with LMA such as blood staining on the mask and sore throat were also recorded.ResultsWithin each group, the OLP was higher in the supine position than that in the lateral position with or without pneumoperitoneum (P < 0.01). However, pneumoperitoneum did not further decrease the OLP. The OLP with PLMA was higher compared with SLMA regardless of the position and pneumoperitoneum (P < 0.05 or 0.01). There was no significant difference in the number of patients in Class I/II/III for ventilation scores in the lateral position with pneumoperitoneum (83/7/2 in PLMA group and 76/14/2 in SLMA group, respectively). The incidence of adverse events was comparable in both groups.ConclusionOur data demonstrate that the PLMA has a higher OLP in comparison with the SLMA in the lateral position for laparoscopic surgery. Both devices provide comparably adequate ventilatory efficiency.

      Abstract: BackgroundUnintentional perioperative hypothermia causes serious adverse effects to surgical patients. Thermal suit (T-Balance®) is an option for passive warming perioperatively. We hypothesized that the thermal suit will not maintain normothermia more efficiently than conventional cotton clothes when also other preventive procedures against unintentional hypothermia are used.MethodsOne hundred patients were recruited to this prospective, randomized trial. They were allocated to the Thermal Suit group or a Control group wearing conventional hospital cotton clothes. All patients received our institution's standard treatment against unintentional hypothermia including a warming mattress, a forced-air upper body warming blanket and a warming device for intravenous fluids. Eardrum temperature was measured pre-operatively. In the operating room and post-anaesthesia care unit temperatures were measured from four locations: oesophagus, left axilla, dorsal surface of the left middle finger and dorsum of the left foot. The primary outcome measure was temperature change during robotic-assisted laparoscopic radical prostatectomy.ResultsThe temperatures of 96 patients were analysed. There was no difference in mean core temperatures, axillary temperatures or skin temperatures on the finger between the groups. Only foot dorsum temperatures were significantly lower in the Thermal Suit group. Intraoperative temperature changes were similar in both groups. In the post-anaesthesia care unit temperature changes were minimal and they did not differ between the groups.ConclusionProvided that standard preventive procedures in maintaining normothermia are effective the thermal suit does not provide any additional benefit over conventional cotton clothes during robotic-assisted laparoscopic radical prostatectomy.

  • Simulation-based training program with deliberate practice for
           ultrasound-guided jugular central venous catheter placement
    • Authors: M. A. Corvetto; J. C. Pedemonte, D. Varas, C. Fuentes, F. R. Altermatt
      Abstract: BackgroundCurrent evidence supports the utility of simulation training for bedside procedures such as ultrasound-guided jugular central venous catheter (CVC) insertion. However, a standardized methodology to teach procedural skills has not been determined yet. The aim of this study was to evaluate the effectiveness of a simulation-based training program for improving novice technical performance during ultrasound-guided internal jugular CVC placement.MethodsPostgraduate year 1 (PGY-1) residents from anesthesiology, emergency medicine, cardiology, ICU, and nephrology specialties were trained in four deliberate practice sessions. Learning objectives included principles of ultrasound (US), preparation (gown, glove, draping), procedural skills I (US scanning and puncture), and procedural skills II (catheter insertion). CVC technical proficiency was tested pre- and post-training using hand-motion analysis with the Imperial College Surgical Assessment Device (ICSAD) and a global rating scale (GRS).ResultsThirty-five PGY-1 residents successfully completed the program. These novices' GRS scores improved significantly after the training (P < 0.001). Total path length measured with the ICSAD decreased significantly after the training (P = 0.008). Procedural time decreased significantly after training from 387 (310–501) seconds to 200 (157–261) seconds (median and interquartile range) (P = 0.029).ConclusionThis simulation-training program based on deliberate practice significantly increased the technical skills of residents in US-guided short-axis, out-of-plane internal jugular CVC placement. Data also confirm the validity of the ICSAD as an assessment tool for ultrasound-guided internal jugular CVC placement learning.
