Introduction: The association between chest compression (CC) pause duration and pediatric in-hospital cardiac arrest (IHCA) survival outcomes is unknown. We hypothesized that longer maximum CC pause durations are associated with worse survival and neurological outcomes. Methods: Cohort study of all index pediatric IHCAs (<18 years of age) ≥1 min in the Pediatric Resuscitation Quality (PediRES-Q) Network from July 2015 through December 2019. We used multivariate logistic regression with mixed effects and robust standard errors to analyze association of 5-sec increments of longest CC pause duration with survival and neurologic outcomes. Favorable neurological outcome was defined as Pediatric Cerebral Performance Category (PCPC) at discharge ≤3 or no change from baseline. Results: We identified 371 index IHCAs: median [Q1,Q3] age 2.6 [0.6,9.4] years, female 46%, shockable rhythm 13%, CPR duration 23 [9,47] min. Median length of the longest pause was 17 [8,27] sec. Each 5 sec increase in longest CC pause duration was associated with 6% lower odds for survival with favorable neurological outcome, even after adjusting for age, defibrillation, intubation, extracorporeal CPR, illness category, hypotension as etiology for arrest, CC depth, and clustering by site (aOR 0.94 [95% CI:0.88-0.99], p=0.04). Analyses controlling for the same factors demonstrated an association of longest pause duration with lower odds for survival to hospital discharge (aOR 0.94 [95% CI: 0.90-0.99, p=0.02) and return of spontaneous circulation (aOR 0.91 [(95% CI: 0.86-0.96], p=0.001). Conclusions: Longest CC pause duration is associated with favorable neurological outcome, survival to hospital discharge, and return of spontaneous circulation following pediatric IHCA, even when controlling for known confounders and clustering by site. Each 5 sec. increment in longest CC pause duration was associated with 6% lower odds for survival with favorable neurological outcome.

Background: The early and timely defibrillation in shockable rhythm of out-of-hospital cardiac arrest (OHCA) by prehospital EMS providers is crucial for successful resuscitation. In emergency medical service (EMS) system, where advanced cardiac life support could not be fully provided before hospital transport, optimal range of prehospital defibrillation attempts is debatable. We evaluated association between number of prehospital defibrillation attempts and survival outcomes in OHCA patients who were unresponsive to field resuscitation and defibrillations. Methods: This is a retrospective observational study using nationwide OHCA registry of Korea from 2013 to 2016. Adult EMS treated OHCA with presumed cardiac origin with shockable initial ECG rhythm were enrolled. Final analysis was performed in patients who did not achieve return of spontaneous circulation (ROSC) on scene before hospital transport. We categorized number of prehospital defibrillation attempt into 3 groups: ≤3 attempts, 4-5 attempts and ≥6 attempts. Primary outcome was favorable neurological outcome at hospital discharge. Multivariable logistic regression modeling was used to evaluate association between neurological outcome and defibrillation attempts. Result: Total 6,679 patients were enrolled for final analyzed. Among total ≤3 defibrillations were attempted in 5015 patients (75.1%), 1050 patients (15.7%) for 4-5 attempts, 614 patient. (9.2%) for ≥6 attempts. Although survival to discharge rate was highest in group with ≤3 defibrillation attempts (8.1% vs. 7.0% vs. 2.9%, p<0.01), survival rate with favorable neurological outcome was highest in group with 4-5 defibrillation attempts (3.0% vs. 4.5% vs. 2.1%, p=0.02). As 4-5 attempts group reference, adjusted odds ratio for favorable neurological outcome of ≤3 attempts was 0.66 (95% CI 0.46 - 0.94) and of ≥6 attempts was 0.47 (95% CI 0.25 - 0.89). Conclusion: For patients with shockable initial cardiac rhythm who were unresponsive to filed defibrillation and resuscitation, moderate amount of defibrillation attempt was associated with favorable neurological outcome compared to fewer defibrillation attempts and prolonged number of defibrillation attempts on scene.

Background: Early cardiopulmonary resuscitation (CPR) and early defibrillation are critical to survival from out-of-hospital cardiac arrest (OHCA). However, few studies have investigated the relationship between time interval from collapse to return of spontaneous circulation (ROSC) and neurologically intact survival. Methods: From the All-Japan OHCA Utstein Registry between 2005 and 2015, we enrolled adult patients achieving prehospital ROSC after witnessed OHCA, inclusive of arrest after emergency medical service responder arrival. The study patients were divided into two groups according to initial cardiac arrest rhythm (shockable versus non-shockable). The collapse-to-ROSC interval was calculated as the time interval from collapse to first achievement of prehospital ROSC. The primary endpoint was 30-day favorable neurological outcome after OHCA. Results: A total of 69,208 adult patients achieving prehospital ROSC after witnessed OHCA were enrolled; 23,017(33.3%) the shockable arrest group and 46,191 (66.7%) the non-shockable arrest group. The shockable arrest group compared with the non-shockable arrest group had significantly shorter collapse-to-ROSC interval (16±10 min vs. 20±13 min, P<0.001) and significantly higher frequency of the favorable neurological outcome (54.9% vs. 15.3%, P<0.001). Frequencies of the favorable neurological outcome after shockable OHCA decreased to 1.2% to 1.5% with every minute that the collapse-to-ROSC interval was delayed (78% at 1 minute of collapse, 68% at 10 minutes, 44% at 20 minutes, 34% at 30 minutes, 16% at 40 minutes, 4% at 50 minutes and 0% at 60 minutes, respectively, P<0.001), and those after non-shockable OHCA decreased to 0.8% to 1.8% with every minute that the collapse-to-ROSC interval was delayed (40% at 1 minute of collapse, 26% at 10 minutes, 11% at 20 minutes, 5% at 30 minutes, 2% at 40 minutes, 0% at 50 minutes and 0% at 60 minutes, respectively, P<0.001). Conclusions: Termination of the collapse-to-ROSC interval to achieve neurologically intact survival after witnessed OHCA was 50 minutes or longer irrespective of initial cardiac arrest rhythm (shockable versus non-shockable), although the neurologically intact survival rate was difference between the two groups.

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.

Introduction: Survival of adult patients with COVID-19 who had an in-hospital cardiac arrest (IHCA) are poor. Characteristics and outcomes for pediatric IHCA patients with COVID-19 are unknown. Hypothesis: We hypothesized that pediatric COVID-19 patients would have worse survival outcomes when compared to non-COVID patients. Methods: A multicenter, multinational cohort of pediatric IHCA in the pediRES-Q collaborative were reviewed (March 1, 2020 - April 1, 2021). We characterized patients with COVID-19 compared to patients without COVID-19 and investigated whether COVID-19 was associated with survival outcomes using multivariate logistic regression with mixed effects. Results: We identified 362 pediatric IHCAs of which 14 were COVID-19 positive. For non-COVID-19 vs COVID-19 patients respectively, median [Q1; Q3] age was 1.0 [0.3; 7.1] vs. 7.1 [1.5; 14.0] years and 42% vs. 43% were female. Immediate cause of arrest was hypotension: 8% vs. 43%, respiratory decompensation: 19% vs. 21%, and hypoxia 22% vs. 36% for non-COVID-19 vs. COVID-19 patients. For non-COVID-19 vs COVID-19 patients, total CPR duration was 10 [4; 33] min vs 19 [5; 33] min (for non-return of spontaneous circulation (ROSC) cases only: 35 [20; 55] min vs 34 [24; 34] min). For non-COVID-19 vs COVID-19 patients, ROSC was 79% vs. 57%, aOR: 0.48 (95% CI: 0.24-0.98), survival to hospital discharge was 45% vs. 29%, aOR: 0.63 (95% CI: 0.25-1.57) and survival with favorable neurological outcome was 39% vs. 21%, aOR: 0.51 (95% CI: 0.16-1.65). Conclusions: In a pediatric resuscitation quality improvement collaborative, pediatric IHCA patients with COVID-19 were older when compared to non-COVID-19 patients. Median CPR duration was >30 minutes for COVID-19 non-survivors, COVID-19 patients had lower chance of ROSC when compared to non-COVID-19 patients but considerably better survival outcomes than those reported for adults.

Introduction: Agonal respiration has been shown to be commonly associated with witnessed events, ventricular fibrillation, and increased survival during out-of-hospital cardiac arrest. There is little information on incidence of gasping for in-hospital cardiac arrest (IHCA). Our “Rapid Response Team” (RRT) missions were monitored between December 2010 and March 2015, and the prevalence of gasping and survival data for IHCA were investigated. Methods: A standardized extended in-hospital Utstein data set of all RRT-interventions occurring at the University Hospital Basel, Switzerland, from December 13, 2010 until March 31, 2015 was consecutively collected and recorded in Microsoft Excel (Microsoft Corp., USA). Data were analyzed using IBM SPSS Statistics 22.0 (IBM Corp., USA), and are presented as descriptive statistics. Results: The RRT was activated for 636 patients, with 459 having a life-threatening status (72%; 33 missing). 270 patients (59%) suffered IHCA. Ventricular fibrillation or pulseless ventricular tachycardia occurred in 42 patients (16% of CA) and were associated with improved return of spontaneous circulation (ROSC) (36 (97%) vs. 143 (67%; p<0.001)), hospital discharge (25 (68%) vs. 48 (23%; p<0.001)), and discharge with good neurological outcome (Cerebral Performance Categories of 1 or 2 (CPC) (21 (55%) vs. 41 (19%; p<0.001)). Gasping was seen in 128 patients (57% of CA; 46 missing) and was associated with an overall improved ROSC (99 (78%) vs. 55 (59%; p=0.003)). In CAs occurring on the ward (154, 57% of all CAs), gasping was associated with a higher proportion of shockable rhythms (11 (16%) vs. 2 (3%; p=0.019)), improved ROSC (62 (90%) vs. 34 (55%; p<0.001)), and hospital discharge (21 (32%) vs. 7 (11%; p=0.006)). Gasping was not associated with neurological outcome. Conclusions: Gasping was frequently observed accompanying IHCA. The faster in-hospital patient access is probably the reason for the higher prevalence compared to the prehospital setting. For CA on the ward without continuous monitoring, gasping correlates with increased shockable rhythms, ROSC, and hospital discharge.

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.

Background: Little is known about the association between serum potassium level on hospital arrival and neurological outcome after out-of-hospital cardiac arrest (OHCA). We investigated whether the serum potassium level on hospital arrival had prognostic indications for patients with OHCA. Methods: This prospective, multicenter observational study conducted in Osaka, Japan (CRITICAL study) enrolled consecutive patients with OHCA transported to 14 participating institutions from 2012 to 2016. We included adult patients aged ⩾18 years with OHCA of cardiac origin who achieved return of spontaneous circulation and whose serum potassium level on hospital arrival was available. Based on the serum potassium level, patients were divided into four quartiles: Q1 (K ⩽3.8 mEq/L), Q2 (3.8< K⩽4.5 mEq/L), Q3 (4.5< K⩽5.6 mEq/L) and Q4 (K >5.6 mEq/L). The primary outcome was one-month survival with favorable neurological outcome, defined as cerebral performance category scale 1 or 2. Results: A total of 9822 patients were registered, and 1516 of these were eligible for analyses. The highest proportion of favorable neurological outcome was 44.8% (189/422) in Q1 group, followed by 30.3% (103/340), 11.7% (44/375) and 4.5% (17/379) in the Q2, Q3 and Q4 groups, respectively ( p<0.001). In the multivariable analysis, the proportion of favorable neurological outcome decreased as the serum potassium level increased ( p<0.001). Conclusions: High serum potassium level was significantly and dose-dependently associated with poor neurological outcome. Serum potassium on hospital arrival would be one of the effective prognostic indications for OHCA achieving return of spontaneous circulation.

Cardiopulmonary resuscitation in patients with out-of-hospital cardiac arrest (OHCA) is associated with poor prognosis. Because the COVID-19 pandemic may have impacted mortality and morbidity, both on an individual level and the health care system as a whole, our purpose was to determine rates of OHCA survival since the onset of the SARS-CoV2 pandemic. We conducted a systematic review and meta-analysis to evaluate the influence of COVID-19 on OHCA survival outcomes according to the PRISMA guidelines. We searched the literature using PubMed, Scopus, Web of Science and Cochrane Central Register for Controlled Trials databases from inception to September 2021 and identified 1775 potentially relevant studies, of which thirty-one articles totaling 88,188 patients were included in this meta-analysis. Prehospital return of spontaneous circulation (ROSC) in pre-COVID-19 and COVID-19 periods was 12.3% vs. 8.9%, respectively (OR = 1.40; 95%CI: 1.06–1.87; p < 0.001). Survival to hospital discharge in pre- vs. intra-COVID-19 periods was 11.5% vs. 8.2% (OR = 1.57; 95%CI: 1.37–1.79; p < 0.001). A similar dependency was observed in the case of survival to hospital discharge with the Cerebral Performance Category (CPC) 1–2 (6.7% vs. 4.0%; OR = 1.71; 95%CI: 1.35–2.15; p < 0.001), as well as in the 30-day survival rate (9.2% vs. 6.4%; OR = 1.63; 95%CI: 1.13–2.36; p = 0.009). In conclusion, prognosis of OHCA is usually poor and even worse during COVID-19.
