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: While survival after in-hospital cardiac arrest (IHCA) has improved in recent years, it remains unknown whether this trend primarily applies to younger IHCA victims or extends to older patients as well. The aim of this study was to assess trends in survival to hospital discharge after adult IHCA across age groups from 2000 to 2016. Methods: This is an observational study of IHCA patients included in the Get With The Guidelines®-Resuscitation registry between January 2000 and December 2016. The primary outcome was survival to hospital discharge, while secondary outcomes included rates of return of spontaneous circulation (ROSC) and neurological outcome at discharge. Patients were stratified into five age groups: < 50 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years. Generalized linear regression was used to obtain absolute survival rates over time. Analyses of interaction were included to assess differences in survival trends between age groups. Results: A total of 234,767 IHCA patients were included for the analyses. The absolute increase in survival per calendar year was 0.8% (95%CI 0.7 - 1.0%, p < 0.001) for patients younger than 50 years, 0.6% (95%CI 0.4 - 0.7%, p < 0.001) for patients between 50 and 59 years, 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients between 60 and 69 years, 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients between 70 and 79 years, and 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients older than 80 years. Further, a significant increase in both rates of ROSC and survival with a good neurological outcome was seen for all age groups. In both unadjusted and adjusted analyses of survival, we observed a significant interaction between calendar year and age group ( p < 0.001), indicating that the rate of improvement in survival over time was significantly different between age groups. Conclusions: For patients with IHCA, survival to discharge, ROSC, and survival to discharge with a good neurological outcome have improved significantly from 2000 to 2016 for all age groups.

In out-of-hospital cardiac arrest (OHCA), the occurrence of temporary periods of return to spontaneous circulation (t-ROSC) has been found to be predictive of survival to hospital discharge. The relationship between the duration of t-ROSCs and OHCA outcome has not been explored yet. The aim of this prospective observational study was to analyze the duration of t-ROSCs during OHCA and its impact on outcome. Defibrillator-recorded OHCA events were analyzed via dedicated software. The number of t-ROSC episodes and their overall durations were recorded. The study endpoint was the good neurologic outcome at hospital discharge. Among 285 patients included in the study, 45 (15.8%) had one or more t-ROSCs. The likelihood of t-ROSC occurrence was higher in patients with a shockable rhythm (p = 0.009). The cumulative length of t-ROSC episodes was significantly higher for patients who achieved sustained ROSC (p < 0.001). The adjusted cumulative t-ROSC length was an independent predictor for good neurological outcome at hospital discharge (OR 1.588, 95% CI 1.017 to 2.481; p = 0.042). According to our findings and data from previous studies, t-ROSC episodes during OHCA should be considered as a favorable prognostic factor, encouraging continuing resuscitative efforts.

Acute thyrotoxicosis (thyroid storm) caused by hyperthyroidism is a rare but severe endocrine imbalance which, in extreme cases, may lead to ventricular fibrillation and ultimately, without intervention, death. The authors attended such an incident and, following clinical interventions, achieved return of spontaneous circulation with a good outcome for the patient and subsequent hospital discharge.

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.

Introduction: The interactions of various variables on out-of-hospital cardiac arrest (OHCA) in the young (1-35 years old) outcomes are complex. Network models have emerged as a way to abstract complex systems and gain insights into relational patterns among observed variables. Hypothesis: Network analysis helps provide qualitative and quantitative insights into how various variables interact with each other and affect outcomes in OHCA in the young. Methods: A mixed graphical network analysis was performed using variables collected by CARES. The network allows the visualization and quantification of each unique interaction between two variables that cannot be explained away by other variables in the data set. The strength of the underlying interaction is proportional to the thickness of the connections (edges) between the variables (nodes). We used the mgm package in R. Results: Figure 1 shows the network of the OHCA in the young cases in Chicago from 2013 to 2017. There are apparent clusters. Sustained return of spontaneous circulation and hypothermia are strongly correlated with survival and neurological outcomes. This cluster is in turn connected to the rest of the network by survival to emergency room. The interaction between any two variables can also be quantified. For example, American Indians cases occur more often in disadvantaged locations when compared to Whites (OR 4.5). The network also predicts how much one node can be explained by adjacent nodes. Only 20% of survival to emergency room is explained by its adjacent nodes. The remaining 80% is attributed to variables not represented in this network. This suggests that interventions to improve this node is difficult unless further data is available. Conclusion: Network analysis provides both a qualitative and quantitative evaluation of the complex system governing OHCA in the young. The networks predictive capability could help in identifying the most effective interventions to improve outcomes.

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: Targeted temperature management (TTM) reduces neurologic injury from out-of-hospital cardiac arrest (OHCA). As the risk of neurologic injury increases with prolonged cardiac arrests, the benefit of TTM may depend upon cardiac arrest duration. We hypothesized that there is a time-dependent effect of TTM on neurologic outcomes from OHCA. Methods: Retrospective, observational study of the Toronto RescuNET Epistry-Cardiac Arrest database from 2007 to 2014. We included adult (>18) OHCA of presumed cardiac etiology that remained comatose (GCS<10) after a return of spontaneous circulation. We used multivariable logistic regression to determine the effect of TTM and the duration of cardiac arrest on good neurologic outcome (Modified Rankin Scale (mRS) 0-3) and survival to hospital discharge while controlling for other known predictors. Results: There were 1496 patients who met our inclusion criteria, of whom 981 (66%) received TTM. Of the patients who received TTM, 59% had a good neurologic outcome compared to 39% of patients who did not receive TTM (p< 0.001). After adjusting for the Utstein variables, use of TTM was associated with improved neurologic outcome (OR 1.60, 95% CI 1.10-2.32; p = 0.01) but not with survival to discharge (OR 1.23, 95% CI 0.90-1.67; p = 0.19). The impact of TTM on neurologic outcome was dependent on the duration of cardiac arrest (p<0.05) (Fig 1). Other significant predictors of good neurologic outcome were younger age, public location, initial shockable rhythm, and shorter duration of cardiac arrest (all p values < 0.05). A subgroup analysis found the use of TTM to be associated with neurologic outcome in both shockable (p = 0.01) and non-shockable rhythms (p = 0.04) but was not associated with survival to discharge in either group (p = 0.12 and p = 0.14 respectively). Conclusion: The use of TTM was associated with improved neurologic outcome at hospital discharge. Patients with prolonged durations of cardiac arrest benefited more from TTM.
