Ontology highlight
ABSTRACT: Aim
Recent studies have shown that the integration of a trained cardiopulmonary resuscitation (CPR) Coach during resuscitation enhances the quality of CPR during simulated paediatric cardiac arrest. The objective of our study was to evaluate the effect of a CPR Coach on adherence to Paediatric Advanced Life Support (PALS) guidelines during simulated paediatric cardiac arrest.Methods
This was a secondary analysis of data collected from a multicentre randomized controlled trial assessing the quality of CPR in teams with and without a CPR Coach. Forty paediatric resuscitation teams were equally randomized into 2 groups (with or without a CPR Coach). The primary outcome was adherence to PALS guidelines during a simulated paediatric cardiac arrest case as measured by the Clinical Performance Tool (CPT). Video recordings were assigned to 2 pairs of expert raters. Raters were trained to independently score performances using the tool.Results
The reliability of the rating was adequate for the Clinical Performance Tool with an intraclass coefficients of 0.67 (95%CI: 0.22 to 0.84). Performance scores of the different teams varied between 51 and 84 points on the Clinical Performance Tool with a mean score of 70. Teams with a CPR Coach demonstrated better adherence to PALS guidelines (i.e. CPT score 73 points) compared to teams without a CPR Coach (68 points, difference 5 points; 95%CI: 1.0-9.3, p = 0.016).Conclusion
In addition to improving CPR quality, the presence of a CPR Coach improves adherence to PALS guidelines during simulated paediatric cardiac arrests when compared with teams without a CPR Coach.

Project description:The American Heart Association (AHA) recommends monitoring cardiopulmonary resuscitation (CPR) quality using end tidal carbon dioxide (ETCO2) or invasive hemodynamic data. The objective of this study was to evaluate the association between clinician-reported physiologic monitoring of CPR quality and patient outcomes.Prospective observational study of index adult in-hospital CPR events using the AHA's Get With The Guidelines - Resuscitation Registry. Physiologic monitoring was defined using specific database questions regarding use of either ETCO2 or arterial diastolic blood pressure (DBP) to monitor CPR quality. Logistic regression was used to evaluate the association between physiologic monitoring and outcomes in a propensity score matched cohort.In the matched cohort, (monitored n=3032; not monitored n=6064), physiologic monitoring of CPR quality was associated with a higher rate of return of spontaneous circulation (ROSC; OR 1.22, CI95 1.04-1.43, p=0.017) compared to no monitoring. Survival to hospital discharge (OR 1.04, CI95 0.91-1.18, p=0.57) and survival with favorable neurological outcome (OR 0.97, CI95 0.75-1.26, p=0.83) were not different between groups. Of index events with only ETCO2 monitoring indicated (n=803), an ETCO2 >10mmHg during CPR was reported in 520 (65%), and associated with improved survival to hospital discharge (OR 2.41, CI95 1.35-4.30, p=0.003), and survival with favorable neurological outcome (OR 2.31, CI95 1.31-4.09, p=0.004) compared to ETCO2 ?10mmHg.Clinician-reported use of either ETCO2 or DBP to monitor CPR quality was associated with improved ROSC. An ETCO2 >10mmHg during CPR was associated with a higher rate of survival compared to events with ETCO2 ?10mmHg.

Project description:Introduction:The probability of surviving a cardiac arrest remains low. International resuscitation guidelines state that extracorporeal cardiopulmonary resuscitation (ECPR) may have a role in selected patients suffering refractory cardiac arrest. Identifying these patients is challenging. This project systematically reviewed the evidence comparing the outcomes of ECPR over conventional-CPR (CCPR), before examining resuscitation-specific parameters to assess which patients might benefit from ECPR. Method:Literature searches of studies comparing ECPR to CCPR and the clinical parameters of survivors of ECPR were performed. The primary outcome examined was survival at hospital discharge or 30 days. A secondary analysis examined the resuscitation parameters that may be associated with survival in patients who receive ECPR (no-flow and low-flow intervals, bystander-CPR, initial shockable cardiac rhythm, and witnessed cardiac arrest). Results:Seventeen of 948 examined studies were included. ECPR demonstrated improved survival (OR 0.40 (0.27-0.60)) and a better neurological outcome (OR 0.10 (0.04-0.27)) over CCPR during literature review and meta-analysis. Characteristics that were associated with improved survival in patients receiving ECPR included an initial shockable rhythm and a shorter low-flow time. Shorter no-flow, the presence of bystander-CPR and witnessed arrests were not characteristics that were associated with improved survival following meta-analysis, although the quality of input data was low. All data were non-randomised, and hence the potential for bias is high. Conclusion:ECPR is a sophisticated treatment option which may improve outcomes in a selected patient population in refractory cardiac arrest. Further comparative research is needed clarify the role of this potential resuscitative therapy.

Project description:BACKGROUND:Performance of cardiopulmonary resuscitation (CPR) causes significant mental stress for rescuers, especially if performed by inexperienced individuals. Our aim was to study electrocardiogram (ECG) alterations in rescuers and its association with gender and CPR performance. METHODS:We included 126 medical students in this prospective, observational simulator study. Each student was equipped with a 3-lead continuous ECG device tracking the individual electrocardiographic output before, during and after CPR. We analyzed variations in heart rate, heart-rate variability (HRV) and ST- and T-wave morphology. RESULTS:Compared to baseline, mean heart rate (bpm) significantly increased during resuscitation and again decreased after resuscitation (from 87 to 97 to 80, p<0.001). Heart-rate variability (the standard deviation of all N-N intervals, SDNN) (ms2) showed the opposite pattern, decreasing during resuscitation and increasing after resuscitation (117 to 92 to 93ms, p<0.001). Abnormalities in T-waves and ST-segments were observed in 29.4% of participants. Maximal heart rate (r = 0.25, p = 0.046) as well as heart rate reactivity (r = 0.7, p<0.001) correlated with hands-on time, a measure of CPR performance. Compared to males, female rescuers had a significantly higher maximal heart rate (136bpm vs. 126bpm, p = 0.008) and lower HRV (SDNN 102 vs. 119ms, p = 0.004) and tended to show more abnormalities in T-waves and ST-segments (36% vs. 21%, p = 0.080). CONCLUSION:CPR causes significant ECG alterations in healthy medical students with ST-segment and T-wave abnormalities, with more pronounced effects in females. Clinical implications of these findings need to be further investigated.

Project description:BackgroundPerformance of sufficient cardiopulmonary resuscitation (CPR) by medical personnel is critical to improve outcomes during cardiac arrest. It has however been shown that even health care professionals possess a lack of knowledge and skills in CPR performance. The optimal method for teaching CPR remains unclear, and data that compares traditional CPR instructional methods with newer modalities of CPR instruction are needed. We therefore conducted a single blinded, randomised study involving medical students in order to evaluate the short- and long-term effects of a classical CPR education compared with a bilateral approach to CPR training, consisting of problem-based learning (PBL) plus high fidelity simulation.MethodsOne hundred twelve medical students were randomized during a curricular anaesthesiology course to a control (n = 54) and an intervention (n = 58) group. All participants were blinded to group assignment and partook in a 30-min-lecture on CPR basics. Subsequently, the control group participated in a 90-min tutor-guided CPR hands-on-training. The intervention group took part in a 45-min theoretical PBL module followed by 45 min of high fidelity simulated CPR training. The rate of participants recognizing clinical cardiac arrest followed by sufficiently performed CPR was the primary outcome parameter of this study. CPR performance was evaluated after the intervention. In addition, a follow-up evaluation was conducted after 6 months.Results51.9% of the intervention group met the criteria of sufficiently performed CPR as compared to only 12.5% in the control group on the day of the intervention (p = 0.007). Hands-off-time as a marker for CPR continuity was significantly less in the intervention group (24.0%) as compared to the control group (28.3%, p = 0.007, Hedges' g = 1.55). At the six-month follow-up, hands-off-time was still significantly lower in the intervention group (23.7% vs. control group: 31.0%, p = 0.006, Hedges' g = 1.88) but no significant difference in sufficiently performed CPR was detected (intervention group: 71.4% vs. control group: 54.5%, p = 0.55).ConclusionPBL combined with high fidelity simulation training leads to a measurable short-term increase in initiating sufficient CPR by medical students immediately after training as compared to classical education. At six month post instruction, these differences remained only partially.

Project description:BACKGROUND:Current guidelines underline the importance of high-quality chest compression during cardiopulmonary resuscitation (CPR), to improve outcomes. Contrary to this many studies show that chest compression is often carried out poorly in clinical practice, and long interruptions in compression are observed. This prospective cohort study aimed to analyse whether chest compression quality changes when a real-time feedback system is used to provide simultaneous audiovisual feedback on chest compression quality. For this purpose, pauses in compression, compression frequency and compression depth were compared. METHODS:The study included 292 out-of-hospital cardiac arrests in three consecutive study groups: first group, conventional resuscitation (no-sensor CPR); second group, using a feedback sensor to collect compression depth data without real-time feedback (sensor-only CPR); and third group, with real-time feedback on compression quality (sensor-feedback CPR). Pauses and frequency were analysed using compression artefacts on electrocardiography, and compression depth was measured using the feedback sensor. With this data, various parameters were determined in order to be able to compare the chest compression quality between the three consecutive groups. RESULTS:The compression fraction increased with sensor-only CPR (group 2) in comparison with no-sensor CPR (group 1) (80.1% vs. 87.49%; P < 0.001), but there were no further differences belonging compression fraction after activation of sensor-feedback CPR (group 3) (P = 1.00). Compression frequency declined over the three study groups, reaching the guideline recommendations (127.81 comp/min vs. 122.96 comp/min, P = 0.02 vs. 119.15 comp/min, P = 0.008) after activation of sensor-feedback CPR (group 3). Mean compression depth only changed minimally with sensor-feedback (52.49 mm vs. 54.66 mm; P = 0.16), but the fraction of compressions with sufficient depth (at least 5 cm) and compressions within the recommended 5-6 cm increased significantly with sensor-feedback CPR (56.90% vs. 71.03%; P = 0.003 and 28.74% vs. 43.97%; P < 0.001). CONCLUSIONS:The real-time feedback system improved chest compression quality regarding pauses in compression and compression frequency and facilitated compliance with the guideline recommendations. Compression depth did not change significantly after activation of the real-time feedback. Even the sole use of a CPR-feedback-sensor ("sensor-only CPR") improved performance regarding pauses in compression and compression frequency, a phenomenon known as the 'Hawthorne effect'. Based on this data real-time feedback systems can be expected to raise the quality level in some parts of chest compression quality.

Project description:Background:We aimed to identify the association of pH value in blood gas assessment with neurological outcome among out-of-hospital cardiac arrest (OHCA) patients treated by extracorporeal cardiopulmonary resuscitation (ECPR). Methods:We retrospectively analyzed the database of a multicenter prospective observational study on OHCA patients in Osaka prefecture, Japan (CRITICAL study), from July 1, 2012 to December 31, 2016. We included adult OHCA patients treated by ECPR. Patients with OHCA from external causes such as trauma were excluded. We conducted logistic regression analysis to identify the odds ratio (OR) and 95% confidence interval (CI) of the pH value for 1 month favorable neurological outcome adjusted for potential confounders including sex, age, witnessed by bystander, CPR by bystander, pre-hospital initial cardiac rhythm, and cardiac rhythm on hospital arrival. Results:Among the 9822 patients in the database, 260 patients were finally included in the analysis. The three groups were Tertile 1: pH ? 7.030, Tertile 2: pH?6.875-7.029, and Tertile 3: pH < 6.875. The adjusted OR of Tertiles 2 and 3 compared with Tertile 1 for 1 month favorable neurological outcome were 0.26 (95% CI 0.10-0.63) and 0.24 (95% CI 0.09-0.61), respectively. Conclusions:This multi-institutional observational study showed that low pH value (< 7.03) before the implementation of ECPR was associated with 1 month unfavorable neurological outcome among OHCA patients treated with ECPR. It may be helpful to consider the candidate for ECPR.

Project description:OBJECTIVE:We aimed to provide the first national estimates of cardiopulmonary resuscitation (CPR) training and awareness of cardiac arrest. DESIGN:A retrospective analysis of a national cross-sectional survey was undertaken. Data were collected online from adults in July 2017 as part of the Heart Foundation of Australia's HeartWatch survey. We used logistic regression to examine demographic factors associated with CPR training. PARTICIPANTS:A national cohort was invited to participate in the survey using purposive, non-probability sampling methods with quotas for age, gender and area of residence, in order to reflect the wider Australian population. The final sample consisted of 1076 respondents. MAIN OUTCOME MEASURE:To determine an estimation of the prevalence of cardiac arrest awareness and CPR training at a national level and the relationship of training to demographic factors. RESULTS:The majority (76%) of respondents were born in Australia with 51% female and 66% aged between 35 and 64 years. Only 16% of respondents could identify the difference between a cardiac arrest and a heart attack. While 56% reported previous CPR training, only 22% were currently trained (within 1?year). CPR training was associated with younger age (35 to 54 years) (OR 1.45, 95% CI 1.06 to 2.0), being born in Australia (OR 1.59, 95%?CI 1.17 to 2.17) and higher levels of education (university, OR 1.86, 95%?CI 1.35 to 2.57). CPR training increased confidence in respondents ability to perform effective CPR and use a defibrillator. Lack of CPR training was the most common reason why respondents would not provide CPR to a stranger. CONCLUSIONS:There is a need to improve the community's understanding of cardiac arrest, and to increase awareness and training in CPR. CPR training rates have not changed over the past decades-new initiatives are needed.

Project description:IntroductionCardiac arrest in pregnancy is rare. Advanced Cardiovascular Life Support courses rarely address interventions specific to obstetric patients, and knowledge gaps are frequent among providers. The Society for Obstetric Anesthesia and Perinatology and American Heart Association have published guidelines regarding management of cardiac arrest in pregnancy, and interdisciplinary simulation training has been advocated to reinforce key management points for this clinical scenario.MethodsIn situ multidisciplinary simulation training was implemented for anesthesia and maternal fetal medicine fellows and obstetric nurses at our hospital. The case was amniotic fluid embolism in a 35-year-old parturient at term. The patient had a witnessed seizure before cardiovascular collapse. Learners were expected to initiate high-quality cardiopulmonary resuscitation and perform a perimortem cesarean delivery within 5 minutes while demonstrating clear communication with each other. The case required a labor room, high-fidelity mannequin, defibrillator, code cart, cesarean section instruments, and simulated medications and intravenous fluids.ResultsParticipants comprised two obstetric anesthesia fellows, three maternal fetal medicine fellows, and three obstetric nurses. Positive feedback about the training and increased perceptions of self-efficacy were received. Potential systems issues were detected and corrected because of the training, highlighting the value of in situ drills.DiscussionWe found it challenging to implement more frequent multidisciplinary sessions, but participants found the experience highly rewarding. We hope to expand the training to all physicians and nurses covering the unit on a regular basis. Modified scenario versions are being used for nursing-only and obstetric resident-only simulations during protected teaching time for those services.

Project description:PURPOSE:To assess the performance of neuroprognostic guidelines proposed by the American Academy of Neurology (AAN), European Resuscitation Council/European Society of Intensive Care Medicine (ERC/ESICM), and American Heart Association (AHA) in predicting outcomes of patients who remain unconscious after cardiac arrest. METHODS:We retrospectively identified a cohort of unconscious post-cardiac arrest patients at a single tertiary care centre from 2011 to 2017 and reviewed hospital records for clinical, radiographic, electrophysiologic, and biochemical findings. Outcomes at discharge and 6 months post-arrest were abstracted and dichotomized as good (Cerebral Performance Category (CPC) scores of 1-2) versus poor (CPC 3-5). Outcomes predicted by current guidelines were compared to actual outcomes, with false positive rate (FPR) used as a measure of predictive value. RESULTS:Of 226 patients, 36% survived to discharge, including 24 with good outcomes; 52% had withdrawal of life-sustaining therapies (WLST) during hospitalization. The AAN guideline yielded discharge and 6-month FPR of 8% and 15%, respectively. In contrast, the ERC/ESICM had a FPR of 0% at both discharge and 6 months. The AHA predictors had variable specificities, with diffuse hypoxic-ischaemic injury on MRI performing especially poorly (FPR 12%) at both discharge and 6 months. CONCLUSIONS:Though each guideline had components that performed well, only the ERC/ESICM guideline yielded a 0% FPR. Amongst the AAN and AHA guidelines, false positives emerged more readily at 6 months, reflective of continuing recovery after discharge, even in a cohort inevitably biased by WLST. Further assessment of predictive modalities is needed to improve neuroprognostic accuracy.

Project description:ObjectivesOutcome from out-of-hospital cardiac arrest (OHCA) highly depends on bystander cardiopulmonary resuscitation (CPR) with high-quality chest compressions (CCs). Precondition is a supine position of the victim on a firm surface. Until now, no study has systematically analysed whether bystanders of OHCA apply appropriate positions to victims and whether the position is associated with a particular outcome.DesignProspective observational cohort study.SettingMetropolitan emergency medical services (EMS) serving a population of 400 000; dispatcher-assisted CPR was implemented. We obtained information from the first EMS vehicle arriving on scene and matched this with data from semi-structured interviews with witnesses of the arrest.ParticipantsBystanders of all OHCAs occurring during a 12-month period (July 2006-July 2007). From 201 eligible missions, 200 missions were fully reported by EMS. Data from 138 bystander interviews were included.Primary and secondary outcome measuresProportion of positions suitable for effective CCs; related survival with favourable neurological outcome at 3 months.ResultsPositioning of victims at EMS arrival was 'supine on firm surface' in 64 cases (32.0%), 'recovery position (RP)' in 37 cases (18.5%) and other positions unsuitable for CCs in 99 cases (49.5%). Survival with favourable outcome at 3 months was 17.2% when 'supine position' had been applied, 13.5% with 'RP' and 6.1% with 'other positions unsuitable for CCs'; a statistically significant association could not be shown (p=0.740, Fisher's exact test). However, after 'effective CCs' favourable outcome at 3 months was 32.0% compared with 5.3% if no actions were taken. The OR was 5.87 (p=0.02).ConclusionIn OHCA, two-thirds of all victims were found in positions not suitable for effective CCs. This was associated with inferior outcomes. A substantial proportion of the victims was placed in RP. More attention should be paid to the correct positioning of victims in OHCA. This applies to CPR training for laypersons and dispatcher-assisted CPR.
