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.

Purpose: Using the out-of-hospital cardiac arrest (OHCA) registry in Japan, we evaluated the effectiveness of pre-hospital advanced airway management under physicians’ presence after adjusting in-hospital treatments. Methods: This was a multicenter cohort study. We registered all consecutive OHCA patients in Japan who, from 1 June 2014 through 31 December 2017, were transported to institutions participating in the Japanese Association for Acute Medicine OHCA Registry. We included OHCA patients performed pre-hospital advanced airway management, who were ≥18 years of age with medical etiology and who received resuscitation from emergency medical services (EMS) personnel and medical professionals in hospitals. The primary outcome was one-month favorable neurological survival.We estimated the propensity score by fitting a logistic regression model that was adjusted for several variables before the arrival of EMS personnel and/ or pre-hospital physician. A multivariable logistic regression analysis in propensity score-matched patients was used to adjust confounders including extracorporeal membrane oxygenation, percutaneous coronary intervention, intra-aortic balloon pumping, and targeted temperature management. Results: We analyzed 9,672 patients. Among them, 2.3% (N = 218) had a neurologically favorable outcome. The adjusted odds ratio (AOR) of pre-hospital advanced airway management under physicians’ presence compared with their absence for primary outcome was 0.96 (95% confidence interval (CI): 0.61-1.51). Among first documented non-shockable cardiac rhythm, the AOR was 3.10 (95% CI: 1.05-10.77). Among first documented shockable cardiac rhythm, the AOR was 0.90 (95% CI: 0.53-1.53). Conclusion: In Japan, pre-hospital advanced airway management under physicians’ presence was not associated with one-month favorable neurological survival among patients with first documented shockable cardiac rhythm, whereas it was associated with a neurologically favorable outcome among patients with first documented non-shockable cardiac rhythm.

Introduction: Although studies have shown that bystander cardiopulmonary resuscitation (CPR) in witnessed out-of-hospital cardiac arrest (OHCA) is associated with better neurological prognosis, whether bystander and Emergency Medical Service (EMS) interventions are associated with prognosis in unwitnessed OHCA patients is not fully elucidated. We aimed to investigate the prognostic importance of bystander and EMS interventions among unwitnessed OHCA patients in Japan. Methods and Results: This study was a nation-wide population-based observational study of OHCA in Japan from 2011 to 2015 based on data from the All-Japan Utstein Registry. The outcome measures were neurological outcome and survival at 30-day. The neurologically favorable outcome was defined as Glasgow-Pittsburgh cerebral performance category score 1 or 2. First, to investigate the effectiveness of bystander interventions, we included 105,655 unwitnessed cardiogenic OHCA patients (aged 18-80 years). Of these, 1,614 (1.5%) showed neurologically favorable outcome and 3,273 (3.1%) survived at 30-day. Multivariate logistic regression analysis adjusting for age, sex, geographical region, year and EMS response time showed that bystander CPR was associated with neurologically favorable outcome (adjusted odds ratio [aOR] 1.49, 95% CI 1.35-1.65, P<0.001). Additionally, to investigate the effectiveness of EMS interventions for patients with non-shockable rhythm, we examined 43,342 patients who were performed public CPR and had the initial rhythm of pulseless electrical activity (PEA) or asystole. Of these, 101 (0.2%) showed neurologically favorable outcome and 453 (1.0%) were survival at 30-day. Advanced airway management by EMS was negatively associated with neurologically favorable outcome (aOR 0.55, 95% CI 0.37-0.81, P=0.003) and administration of epinephrine by EMS was associated with survival (aOR 2.35, 95% CI 1.89-2.92, P<0.001). Conclusions: Among unwitnessed OHCA patients, bystander CPR was associated with neurologically favorable prognosis. For unwitnessed OHCA patients with non-shockable rhythm, epinephrine administration was associated with survival, but advanced airway management was negatively associated with neurological outcome.

Abstract Objective To determine survival associated with advanced airway management (AAM) compared with no AAM for adults with out-of-hospital cardiac arrest. Design Cohort study between January 2014 and December 2016. Setting Nationwide, population based registry in Japan (All-Japan Utstein Registry). Participants Consecutive adult patients with out-of-hospital cardiac arrest, separated into two sub-cohorts by their first documented electrocardiographic rhythm: shockable (ventricular fibrillation or pulseless ventricular tachycardia) and non-shockable (pulseless electrical activity or asystole). Patients who received AAM during cardiopulmonary resuscitation were sequentially matched with patients at risk of AAM within the same minute on the basis of time dependent propensity scores. Main outcome measures Survival at one month or at hospital discharge within one month. Results Of the 310 620 patients eligible, 8459 (41.2%) of 20 516 in the shockable cohort and 121 890 (42.0%) of 290 104 in the non-shockable cohort received AAM during cardiopulmonary resuscitation. After time dependent propensity score sequential matching, 16 114 patients in the shockable cohort and 236 042 in the non-shockable cohort were matched at the same minute. In the shockable cohort, survival did not differ between patients with AAM and those with no AAM: 1546/8057 (19.2%) versus 1500/8057 (18.6%) (adjusted risk ratio 1.00, 95% confidence interval 0.93 to 1.07). In the non-shockable cohort, patients with AAM had better survival than those with no AAM: 2696/118 021 (2.3%) versus 2127/118 021 (1.8%) (adjusted risk ratio 1.27, 1.20 to 1.35). Conclusions In the time dependent propensity score sequential matching for out-of-hospital cardiac arrest in adults, AAM was not associated with survival among patients with shockable rhythm, whereas AAM was associated with better survival among patients with non-shockable rhythm.

Cardiac arrests are resulted by various aetiology including respiratory cause. Advanced airway placement is an important prehospital intervention for oxygenation and ventilation in respiratory cardiac arrest. We evaluated the association between of advanced airway method and neurologic outcome in arrest with respiratory cause. Adult witnessed non-traumatic OHCA (out-of-hospital cardiac arrest) treated by emergency medical service (EMS) providers in 2013–2017 were enrolled in a nationwide OHCA database. The association between airway management methods (endotracheal intubation (ETI), supraglottic airway (SGA) and bag valve mask (BVM)) and outcome were evaluated according to the presumed cause of cardiac arrest (cardiac, respiratory or others). The primary outcome was good neurological recovery at discharge. Multivariable logistic regression models with interaction analysis was conducted. Of 40,443 eligible OHCA patients, the cause of arrest of 90.0%, 7.5%, and 2.4% of patients were categorized as cardiac, respiratory and others, respectively. There were no statistically significant differences in the effect of the advanced airway type on good neurologic recovery in the total population (adjusted odds ratio (aOR) 0.96 (0.81–1.14) for ETI; 1.01 (95% confidence intervals (CI) 0.93–1.11) for BVM). However, ETI was associated with better neurologic recovery than SGA or BVM in OHCA in cardiac arrest with suspected respiratory cause (aOR 3.12 (95% CI 1.24–7.80) for ETI; 0.99 (95% CI 0.51–1.91) for BVM). Prehospital ETI was associated with good neurologic outcome when the cause of arrest was respiratory. ETI may be considered initially when a respiratory cause is suspected on the scene.
