Introduction: The 2015 American Heart Association Guidelines for Cardiopulmonary Resuscitation recommend intravenous (IV) or intraosseous (IO) epinephrine administration for pediatric patients with out-of-hospital cardiac arrest (OHCA). However, it is unknown whether the route of epinephrine administration affects patient outcomes. Our objective was to evaluate the association between the route of epinephrine administration and survival. Methods: We conducted a secondary analysis of the Resuscitation Outcomes Consortium Epistry, a prospective multicenter OHCA registry from 2011 through 2015 in North America. We included pediatric patients (≤18 years) with OHCA for whom emergency medical services (EMS) providers attempted resuscitation and administered epinephrine via IV or IO. We excluded patients who received endotracheal epinephrine, received both IV and IO epinephrine, received IV epinephrine with failed IO access, and received IO epinephrine with failed IV access. The primary outcome was survival to hospital discharge. We used multivariable logistic regression and adjusted for age, sex, initial rhythm, location of arrest, witness status, receiving layperson cardiopulmonary resuscitation, 9-1-1 call to EMS arrival, and advanced airway management. We also conducted a propensity score matching analysis with the same covariates. Results: Of the eligible 831 pediatric patients with OHCA, 226 (27.2%) received IV epinephrine and 605 (72.8%) IO epinephrine. Median interval between 9-1-1 call and epinephrine administration was 16.4 minutes (interquartile range [IQR] 12.9-21.0) in IV group and 16.2 minutes (IQR 12.8-20.0) in IO group. In the logistic regression model, the adjusted odds ratio (OR) of the IO group for survival to hospital discharge was 0.99 (95% confidence interval [CI] 0.41-2.40), compared with the IV group. Similarly, in the propensity score analysis, 218 patients underwent matching with good balance (standardized differences <0.25 for all covariates) and the OR of the IO group for survival to hospital discharge was 1.00 (95% CI 0.38-2.62). Conclusions: We observed no significant difference in survival to hospital between pediatric patients with OHCA who received epinephrine via IV and IO routes.

Abstract Background In-hospital cardiac arrest is a major public health issue. It is a serious condition; most probably end up with death within a few minutes even with corrective measures. However, cardiopulmonary resuscitation is expected to increase the probability of survival and prevent neurological disabilities in patients with cardiac arrest. Having a pooled prevalence of survival to hospital discharge after cardiopulmonary resuscitation is vital to develop strategies targeted to increase probability of survival among patients with cardiac arrest. Therefore, this systematic review and meta-analysis was aimed to assess the pooled prevalence of survival to hospital discharge among pediatric patients who underwent cardiopulmonary resuscitation for in-hospital cardiac arrest. Methods PubMed, Google Scholar, and Cochrane review databases were searched. To have current (five-year) evidence, only studies published in 2016 to 2020 were included. The weighted inverse variance random-effects model at 95%CI was used to estimate the pooled prevalence of survival. Heterogeneity assessment, test of publication bias, and subgroup analyses were also employed accordingly. Results Twenty-five articles with a total sample size of 28,479 children were included in the final analysis. The pooled prevalence of survival to hospital discharge was found to be 46% (95% CI = 43.0–50.0%; I2 = 96.7%; p < 0.001). Based on subgroup analysis by “continent” and “income level”, lowest prevalence of pooled survival was observed in Asia (six studies; pooled survival =36.0% with 95% CI = 19.01–52.15%; I2 = 97.4%; p < 0.001) and in low and middle income countries (six studies, pooled survival = 34.0% with 95% CI = 17.0–51.0%, I2 = 97.67%, p < 0.001) respectively. Conclusion Although there was an extremely high heterogeneity among reported results (I2 = 96.7%), in this meta-analysis more than half of pediatric patients (54%) who underwent cardiopulmonary resuscitation for in-hospital cardiac arrest did not survived to hospital discharge. Therefore, developing further strategies and encouraging researches might be crucial.

Introduction: The optimal timing of epinephrine administration in shockable initial rhythm out-of-hospital cardiac arrest (OHCA) is unclear. Hypothesis: Early compared to late epinephrine following first electrical defibrillation attempt is associated with better outcomes in shockable initial rhythm OHCA. Methods: We conducted a retrospective study in adults with shockable initial rhythm OHCA from 2011-2015 in North America. We used multivariable logistic regression to assess associations between timing of epinephrine and prehospital return of spontaneous circulation (ROSC), survival to hospital discharge, and hospital discharge with favorable neurological outcome (modified Rankin Scale score≤3). We used propensity-score-matching and subgroup analyses to assess robustness of associations. Results: Of 6416 patients, median age was 64 (IQR: 54-74) years, 5136 (80%) were men, 2226 (35%) received epinephrine within four minutes after first defibrillation, 5119 (80%), 1237 (19%), and 996 (16%) had prehospital ROSC, survival to hospital discharge, and favorable neurological outcome at discharge respectively. Adjusted for confounders, we observed lower odds of prehospital ROSC (OR=0.95, 95%CI 0.94-0.96; p<0.001), survival to hospital discharge (OR=0.91, 95%CI 0.89-0.92; p<0.001), and favorable neurological outcomes at discharge (OR=0.92, 95%CI 0.90-0.93; p<0.001) per minute later epinephrine administration. Compared to epinephrine administration within four minutes following first defibrillation attempt, later epinephrine was associated with lower odds of prehospital ROSC (OR=0.58, 95%CI 0.51-0.68; p<0.001), survival to hospital discharge (OR=0.50, 95%CI 0.43-0.58; p<0.001), and favorable neurological outcome at discharge (OR=0.51, 95%CI 0.43-0.59; p<0.001). Associations remained significant in a well-balanced propensity score matched cohort and subgroup analyses by witness status, EMS response time, and total epinephrine dose. Conclusion: In shockable initial rhythm OHCA, early compared to late epinephrine administration following first defibrillation attempt was associated with better odds of prehospital ROSC, survival to hospital discharge, and hospital discharge with favorable neurological outcome.

Background: To achieve intact neurological survival is a challange for pediatric cardiac arrest. Here we describe the outcome and identify the factors associated with survival among pediatric patients following extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital pediatric cardiac arrest. Method: Retrospective study of 27 pediatric in-hospital cardiac arrest who received extracorporeal membrane oxygenation during active cardiopulmonary resuscitation-.The primary outcome was survival to hospital discharge. The secondary outcome was neurological status after ECPR at hospital discharge and late follow-up. Continuous variables were expressed as medians (inter-quartile range) Results: . We identified 27 ECPR events. The survival rate to hospital discharge was 41% (11/27). The non-survivors had higher serum lactate levels (14 [10.2–19.6] mmol/L vs 8.5 [4.4 –12.6] mmol/L, p < 0.01), longer durations of cardiopulmonary resuscitation (CPR) (60 [37– 81] minutes vs 45 [25–50] minutes, p < 0.05) with longer activating time for ECMO (12.5 [7.5–33.8] minutes vs 5 [0 –10] minutes, p<0.01),and more renal failure after ECPR (68% 11 / 16 vs 9% 1 / 11 , p < 0.01). By multivariate analysis, the earlier cohort and renal failure after ECPR were independent risk factors for mortality. Among the11 survivors, 10 of them had good neurological outcomes. Conclusions: ECPR successfully rescued some pediatric patients who failed rescue with conventional in-hospital CPR. Good neurological outcomes were achieved in the majority of the survivors. Early cohort and post-ECPR renal failure were associated with poor outcomes. Early activation of the ECMO team could possibly shorten the CPR duration and improve the ECPR results.

Abstract Introduction: For patients with out-of-hospital cardiac arrest (OHCA) without return of spontaneous circulation under advanced life support, extracorporeal cardiopulmonary resuscitation (ECPR) is the only lifesaving option. This study aimed to analyse the predictors of favourable neurological outcomes (FO, cerebral performance category 1-2) at hospital discharge among patients with OHCA following ECPR.Methods: In this single-centre retrospective study, 126 patients with OHCA who received ECPR between January 2012 and December 2019 were enrolled. The primary outcome was the FO at hospital discharge. The predictors of FO were assessed using multiple logistic regression analysis. Patients with an initial shockable rhythm were further analysed according to the cardiac rhythm at the time of hospital arrival. Results: Among the patients who received ECPR, the FO at hospital discharge was 21%. Certain resuscitation variables were associated with FO including witnessed collapse (P=0.014), bystander CPR (P=0.05), shorter no-flow time (P=0.008), and a shockable rhythm at hospital arrival (P=0.009). Multiple logistic regression showed that a shockable rhythm at hospital arrival was the only independent predictor of FO at discharge (odds ratio, 3.012; 95% confidence interval, 1.06-8.53; P=0.038). Among patients with an initial shockable rhythm, the group with a shockable rhythm at hospital arrival had a FO of 30%, which was significantly higher than the 11% in the non-shockable rhythm group (P=0.043).Conclusions: In patients with OHCA who received ECPR, a shockable rhythm at the time of hospital arrival was associated with favourable neurological outcomes at discharge. The ECPR selection criteria could consider the rhythm at hospital arrival.

Abstract Introduction This study is aimed to investigate the association of intraosseous (IO) versus intravenous (IV) route during cardiopulmonary resuscitation (CPR) with outcomes after out-of-hospital cardiac arrest (OHCA). Methods We systematically searched PubMed, Embase, Cochrane Library and Web of Science from the database inception through April 2020. Our search strings included designed keywords for two concepts, i.e. vascular access and cardiac arrest. There were no limitations implemented in the search strategy. We selected studies comparing IO versus IV access in neurological or survival outcomes after OHCA. Favourable neurological outcome at hospital discharge was pre-specified as the primary outcome. We pooled the effect estimates in random-effects models and quantified the heterogeneity by the I2 statistics. Time to intervention, defined as time interval from call for emergency medical services to establishing vascular access or administering medications, was hypothesized to be a potential outcome moderator and examined in subgroup analysis with meta-regression. Results Nine retrospective observational studies involving 111,746 adult OHCA patients were included. Most studies were rated as high quality according to Newcastle-Ottawa Scale. The pooled results demonstrated no significant association between types of vascular access and the primary outcome (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.27–1.33; I2, 95%). In subgroup analysis, time to intervention was noted to be positively associated with the pooled OR of achieving the primary outcome (OR: 3.95, 95% CI, 1.42–11.02, p: 0.02). That is, when the studies not accounting for the variable of “time to intervention” in the statistical analysis were pooled together, the meta-analytic results between IO access and favourable outcomes would be biased toward inverse association. No obvious publication bias was detected by the funnel plot. Conclusions The meta-analysis revealed no significant association between types of vascular access and neurological outcomes at hospital discharge among OHCA patients. Time to intervention was identified to be an important outcome moderator in this meta-analysis of observation studies. These results call for the need for future clinical trials to investigate the unbiased effect of IO use on OHCA CPR.

Abstract Background: Targeted temperature management (TTM) is recommended for unconscious patients after a cardiac arrest. However, its effectiveness in patients with post-cardiac arrest syndrome (PCAS) by hanging remains unclear. Therefore, this study aimed to investigate the relationship between TTM and favorable neurological outcomes in patients with PCAS by hanging.Methods: This study was a retrospective analysis of the Japanese Association for Acute Medicine out-of-hospital cardiac arrest (OHCA) registry between June 2014 and December 2017 among patients with PCAS admitted to the hospitals after an OHCA caused by hanging. A multivariate logistic regression analysis was performed to estimate the propensity score and to predict whether patients with PCAS by hanging receive TTM. We compared patients with PCAS by hanging who received TTM (TTM group) and those who did not (non-TTM group) using propensity score analysis.Results: A total of 199 patients with PCAS by hanging were enrolled in this study. Among them, 43 were assigned to the TTM group and 156 to the non-TTM group. Logistic regression model adjusted for propensity score revealed that TTM was not associated with favorable neurological outcome at 1-month (adjusted odds ratio [OR]: 1.38, 95% confidence interval [CI]: 0.27–6.96). Moreover, no difference was observed in the propensity score-matched cohort (adjusted OR: 0, 73, 95% CI: 0.10–4.71) and in the inverse probability of treatment weighting-matched cohort (adjusted OR: 0.63, 95% CI: 0.15–2.69).Conclusions: TTM was not associated with increased favorable neurological outcomes at 1-month in patients with PCAS after OHCA by hanging.

Background: Previous investigations in human out of hospital cardiac arrest (OHCA) due to ventricular fibrillation (VF) have shown that the frequency-based waveform characteristic, amplitude spectral area (AMSA) predicts defibrillation success and is associated with survival to hospital discharge. We evaluated the relative strength of factors associated with hospital discharge including witnessed/unwitnessed status, chest compression (CC) quality and AMSA. We then investigated if there is a threshold value for AMSA that can identify patients who are unlikely to survive. Methods: Adult OHCA patients (age ≥18), with initial rhythm of VF from an Utstein-Style database (collected from 2 EMS systems) were analyzed. AMSA was measured from the waveform immediately prior to each shock, and averaged for each individual subject (AMSA-ave). Univariate and stepwise multivariable logistic regression, and receiver-operator-characteristic (ROC) analyses were performed. Factors analyzed: age, sex, witnessed status, time from dispatch to monitor/defibrillator application, number of shocks, mean CC rate, depth, and release velocity (RV). Results: 140 subjects were analyzed, [104 M (74%), age 62 ± 14 yrs, witnessed 65%]. Survival was 38% in witnessed and 16% in unwitnessed arrest. In univariate analyses, age (P=0.001), witnessed status (P=0.009), AMSA-ave (P<0.001), mean CC depth (P=0.025), and RV (P< 0.001) were associated with survival. Stepwise logistic regression identified AMSA-ave (P<0.001), RV (P=0.001) and age (P=0.018) as independently associated with survival. The area under the curve (ROC analysis) was 0.849. The probability of survival was < 5% in witnessed arrest for AMSA-ave < 5 mV-Hz, and in unwitnessed arrest for AMSA-ave < 15 mV-Hz. Conclusion: In OHCA with an initial rhythm of VF, AMSA-ave and CC RV are highly associated with survival. Further study is needed to evaluate whether AMSA-ave may be useful to identify patients highly unlikely to survive.

Introduction: It is unclear whether prehospital advanced airway management (AAM: endotracheal intubation and supraglottic airway device placement) for pediatric patients with out-of-hospital cardiac arrest (OHCA) improves patient outcomes. Objective: To test the hypothesis that prehospital advanced airway management during pediatric OHCA is associated with patient outcomes. Methods: We conducted a secondary analysis of a nationwide, prospective, population-based OHCA registry in Japan. We included pediatric patients (<18 years) with OHCA in whom emergency medical services (EMS) personnel resuscitated and transported to medical institutions during 2014 and 2015. The primary outcome was one-month survival. Secondary outcome was one-month survival with favorable functional outcome, defined as cerebral performance category score 1 or 2. Patients who received AAM during cardiopulmonary resuscitation by EMS personnel at any given minute were sequentially matched with patients at risk of receiving AAM within the same minutes based on time-dependent propensity score calculated from a competing risk regression model in which we treated prehospital return of spontaneous circulation as a competing risk event. Results: We included 2,548 patients; 1,017 (39.9%) were infants (<1 year), 839 (32.9%) were children (1 year to 12 years), and 692 (27.2%) were adolescents. Of the 2,548, included patients, 336 (13.2%) underwent prehospital AAM during cardiac arrest. In the time-dependent propensity score matched cohort (n = 642), there were no significant differences in one-month survival (AAM: 32/321 [10.0%] vs. no AAM: 27/321 [8.4%]; odds ratio, 1.33 [95% CI, 0.80 to 2.21]) and one-month survival with favorable functional outcome (AAM: 6/321 [1.9%] vs. no AAM: 5/321 [1.6%]; odds ratio, 1.48 [95% CI, 0.41 to 5.40]). Conclusions: Among pediatric patients with OHCA, we found no associations between prehospital AAM and favorable patient outcomes.

Background: Delay in administration of the first epinephrine dose has been shown to be associated with a lower chance of good outcome in adult, in-hospital, non-shockable cardiac arrest. Whether this association is true in pediatric in-hospital non-shockable cardiac arrest remains unknown. Methods: We utilized the Get With the Guidelines - Resuscitation national registry to identify pediatric patients (age < 18 years) with an in-hospital cardiac arrest between 2000 and 2010. We included patients with an initial non-shockable rhythm who received at least one dose of epinephrine. To assess the association between time to epinephrine administration and survival to discharge we used multivariate logistic regression models with adjustment for multiple predetermined variables including age, gender, illness category, pre-existing mechanical ventilation, monitored, witnessed, location, time of the day/week, year of arrest, insertion of an airway, initial rhythm, time to initiation of cardiopulmonary resuscitation, hospital type and hospital teaching status. Secondary outcomes included return of spontaneous circulation (ROSC) and neurological outcome. Results: 1,131 patients were included. Median age was 9 months (quartiles: 21 days - 6 years) and 46% were female. Overall survival to hospital discharge was 29%. Longer time to epinephrine was negatively associated with survival to discharge in multivariate analysis (OR: 0.94 [95%CI: 0.90 - 0.98], per minute delay). Longer time to epinephrine was negatively associated with ROSC (OR: 0.93 [95%CI: 0.90 - 0.97], per minute delay) but was not statistically significantly associated with survival with good neurological outcome (OR: 0.95 [95%CI: 0.89 - 1.03], per minute delay). Conclusions: Delay in administration of epinephrine during pediatric in-hospital cardiac arrest with a non-shockable rhythm is associated with a lower chance of ROSC and lower survival to hospital discharge.
