Background: A series of cardiopulmonary resuscitation (CPR) maneuvers of the CoSTR has been updated since first international guidelines was published in 2000. We investigated whether CPR, especially defibrillation protocol, based on the CoSTR update improves neurologically intact survival after shockable out-of-hospital cardiac arrest (OHCA). Methods: From the All-Japan Utstein Registry between 2005 and 2015, we enrolled adult patients with witnessed shockable OHCA. Study patients were divided into 3 groups according to each CPR recommendation era (the Guidelines 2000 group in 2005; 3-stacked-shock protocol era, CoSTR 2005 group between 2006 and 2010; 1-shock protocol [1 shock immediately followed by 2 minutes of CPR] era, and the CoSTR 2010 group between 2006 and 2010; simplified dispatcher chest compressions instruction and 1-shock protocol era). Primary endpoint was favorable 30-day neurological outcome after OHCA. Results: Of the 73,578 study patients, 5,575 (7.6%) received CPR based on the Guidelines 2000, 32,749 (44.5%) the CoSTR 2005, and 35,255 (47.9%) the CoSTR 2010. Crude frequency of favorable 30-day neurological outcome increased significantly whenever the CPR maneuvers were updated (12.3% in the Guidelines 2000 group vs. 19.3% in the CoSTR 2005 group vs. 23.3% in the CoSTR 2010 group, p<0.001). Multivariable logistic-regression analysis for favorable 30-day neurological outcome showed that adjusted odds ratio (reference, the Guidelines 2000 group) was 1.89 (95% CI, 1.72-2.07) in the CoSTR 2005 group and 2.71 (95% CI, 2.47-2.97) in the CoSTR 2010 group. Other independent predictors were age, sex, collapse-to-CPR interval, call-to-scene interval, witnessed and/or bystander CPR status, and cause of cardiac arrest. On the other hand, some advanced life support maneuvers were not acceptable; adjusted odds ratio of 0.37 (95%CI, 0.35-0.39) in advanced airway management (reference, bug-mask ventilation) and 0.36 (95%CI, 0.33-0.38) in intravenous epinephrine (reference, no epinephrine). Conclusions: Defibrillation protocol update based on the CoSTR was the preferable approach to resuscitation for adult patients with witnessed shockable OHCA. However, prehospital epinephrine and advanced airway management were not helpful.

BACKGROUND AHA guidelines for cardiopulmonary resuscitation (CPR) have recommended that administration of atropine can be considered for asystole or pulseless electrical activity (PEA), because atropine has improved survival to hospital admission in a retrospective review (Ann Emerg Med, 1984), and is inexpensive, easy to administer, and has few side effects. However, there are insufficient data in humans. METHODS We assessed the effects of atropine in 7,443 adults patients with asystole or PEA arrest from the SOS-KANTO study: a prospective, multicenter, observational trial. The medications for asystole or PEA arrest were managed according to the advanced cardiovascular life support algorithm of the CPR guidelines (i.e. a 1-mg dose of epinephrine was administered intravenously every 3 to 5 minutes and a1-mg dose of atropine was administered intravenously every 3 to 5 minutes; maximum total of 3 doses). The primary endpoint was a favorable neurological outcome 30 days after cardiac arrest. RESULTS Of the 7,443 adult patients who had out-of-hospital cardiac arrest with asystole or PEA, I,708(23%) were treated with epinephrine and atropine and 5,735(77%) were treated with epinephrine. At baseline, the epinephrine and atropine group had significantly higher proportions of cardiac cause, witnessed arrest, and bystander CPR attempt than the epinephrine group. However, the two groups had a similar frequency of the favorable neurological outcome (0.3% in each group, p=0.805). Multiple logistic-regression analysis showed that the adjusted odds ratio for the favorable neurological outcome was 0.6 (95% CI 0.2–1.7, p=0.37) after epinephrine and atropine (compared with epinephrine). On the other hand, the epinephrine and atropine group had significantly higher rate of return of spontaneous circulation (ROSC) than the epinephrine group (35% vs. 23%, p<0.0001), and the adjusted odds ratio for ROSC was 1.6 (95% CI 1.4 –1.7, p<0.0001) after epinephrine and atropine (compared with epinephrine). CONCLUSIONS We demonstrated that administration of atropine during management of asystole or PEA arrest did not increase the frequency of favorable neurological outcome, although the atropine favored initial ROSC.

Background: Effective advanced life support is one of the important link in the chain of survival. In Japan, the emergency medical service (EMS) personnel can perform defibrillation, advanced airway management, intravenous access and administration of epinephrine as an advanced life support intervention for the treatment of out-of-hospital cardiac arrest (OHCA). However, whether these interventions performed by EMS improves neurological outcomes remains unclear. Objective: To evaluate predictors of favorable neurological outcome in patients suffering OHCA with ventricular fibrillation (VF) witnessed by an EMS personnel. Methods: The Fire and Disaster Management Agency (FDMA) of Japan developed a nationwide database of a prospective population-based cohort using an Utstein-style template for OHCA patients since January 2005. To evaluate data after the publication of Guideline2010, data from January 2011 to December 2015 of this database was used for the current analysis. A multivariate logistic-regression analysis was performed to assess factors associated with favorable neurological outcome (defined as Cerebral Performance Category 1 or 2) 1 month after cardiac arrest. Results: Of the 629,471 patients documented for the study period, 2,301 adult patients with an OHCA of cardiac origin and VF for the initial rhythm witnessed by an EMS personnel were included in the present analysis. The overall mortality was 49.6%. Rate of return of spontaneous circulation and favorable neurological outcome were 53.4% and 44.8%, respectively. High age (OR0.387, 95%CI0.316-0.472, p<0.001), delayed defibrillation (OR0.598, 95%CI0.493-0.723, p<0.001), advanced airway management (OR0.305, 95%CI0.223-0.413, p<0.001), administration of epinephrine (OR0.356, 95%CI0.213-0.585, p<0.001) and multiple attempts of defibrillation (OR0.484, 95%CI0.402-0.582, p<0.001) were negatively associated with favorable neurological outcome. Conclusion: In patients with VF witnessed by EMS personnel, resuscitation efforts should simply focus on early defibrillation and CPR without advanced interventions.

Therapeutic hypothermia is beneficial to neurological outcome for comatose survivors after out-of-hospital cardiac arrest. However, there are few data of extracorporeal cardiopulmonary resuscitation (ECPR) for induction of hypothermia for patients with out-of-hospital cardiac arrest. We did a prospective study of ECPR with hypothermia for patients with out-of-hospital cardiac arrest. The criteria for inclusion were an age of 18 to 74 years, a witnessed cardiac arrest, collapse-to-patient’s-side interval <15 minutes, cardiac arrest due to presumed cardiac etiology, and persistent cardiac arrest on ER arrival in spite of the prehospital defibrillations. After arrival at the emergency room, cardiopulmonary bypass plus intra-aortic balloon pumping was immediately performed, and then coronary reperfusion therapy during cardiac arrest was added if needed. Mild hypothermia (34°C for 3 days) was immediately induced during cardiac arrest or after return of spontaneous circulation. We selected suitable patients who received conventional CPR with normothermia among a prospective multi-center observational study of patients who had out-of-hospital cardiac arrest in Kanto region of Japan “the SOS-KANTO study” for the control group. The primary endpoint was favorable neurological outcome at the time of hospital discharge. A total of 558 patients were enrolled; 127 received ECPR with hypothermia and 431 received conventional CPR with normothermia. The ECPR with hypothermia group had significantly higher frequency of the favorable neurological outcome than the conventional CPR with normothermia group (12% vs. 2%, unadjusted odds ratio, 8.1; 95% CI; 3.2 to 20.0). The adjusted odds ratio for the favorable neurological outcome after ECPR with hypothermia was 7.4 (95% CI; 2.8 to 19.3, p<0.0001). Among the ECPR with hypothermia group, early attainment of a target core temperature of 34°C increased its efficacy (adjusted odds ratio, 0.99; 95% CI; 0.98 to 1.00, p=0.04). ECPR with hypothermia improved the chance of neurologically intact survival for adult patients with out-of-hospital cardiac arrest, and the early attainment of a target temperature enhanced its efficacy.

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.

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.

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.

ObjectivesTo investigate the association of prehospital advanced airway management (AAM) on outcomes of emergency medical service (EMS)-witnessed out-of-hospital cardiac arrest (OHCA) according to the location of arrest.MethodsWe evaluated a Korean national OHCA database from 2012 to 2016. Adults with EMS-witnessed, non-traumatic OHCA were included. Patients were categorised into four groups according to whether prehospital AAM was conducted (yes/no) and location of arrest (‘at scene’ or ‘in the ambulance’). The primary outcome was discharge with good neurological recovery (cerebral performance category 1 or 2). Multivariable logistic regression analysis was conducted to evaluate the association between AAM and outcome according to the location of arrest.ResultsAmong 6620 cases, 1425 (21.5%) cases of arrest occurred ‘at the scene’, and 5195 (78.5%) cases of arrest occurred ‘in an ambulance’. Prehospital AAM was performed in 272 (19.1%) OHCAs occurring ‘at the scene’ and 645 (12.4%) OHCAs occurring ‘in an ambulance’. Patients with OHCA in the ambulance who had prehospital AAM showed the lowest good neurological recovery rate (6.0%) compared with OHCAs in the ambulance with no AAM (8.9%), OHCA at scene with AAM (10.7%) and OHCA at scene with no AAM (7.7%). For OHCAs occurring in the ambulance, the use of AAM had an adjusted OR of 0.67 (95% CI 0.45 to 0.98) for good neurological recovery.ConclusionOur data show no benefit of AAM in patients with EMS-witnessed OHCA. For patients with OHCA occurring in the ambulance, AAM was associated with worse clinical outcome.

Abstract Background/Introduction Previous studies have shown that out-of-hospital cardiac arrest (OHCA) occurring at night have poor outcomes compared with OHCA occurring during daytime. On the other hand, nationwide OHCA outcomes have gradually improved in Japan. Purpose We sought to examine whether one-month survival of OHCA differed between daytime and nighttime occurrences, and they differed between the periods of International Resuscitation Guidelines 2005 and 2010. Methods Using the All-Japan Utstein Registry between 2005 and 2015, adult OHCA patients whose collapse was witnessed by a bystander and the call-to-hospital admission interval was shorter than 120 min were included in this study. OHCA patients were divided by period of the International Resuscitation Guideline 2005 and 2010. Guideline 2005 included years from 2006 to 2010, while Guideline 2010 included years from 2011 to 2015. The primary outcome was one-month survival with favorable neurological outcome, defined as Cerebral Performance Category scale of 1 or 2. Daytime, evening, and night were defined as 0700 to 1459 h, 1500 to 2259 h, and 2300 to 0659 h, respectively. Results Among 479,046 cases, 20.3% revealed OHCA occurring at night. OHCA patients occurring at night had lower rate of bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator use than those occurring at both daytime and evening. In addition, of those who received bystander CPR, higher rate of patients received CPR by family members. OHCA patients occurring at night in both guideline periods had significantly worse one-month survival than those occurring during daytime (reference) (adjusted odds ratio, 0.69, 0.64; 95% confidence interval 0.65–0.72, 0.61–0.67; P<0.001, P<0.001, Guideline 2005 and 2010 respectively). OHCA patients occurring during daytime in Guideline 2010 had better one-month survival than those in Guideline 2005 (adjusted odds ratio, 1.29; 95% confidence interval 1.24–1.34; P<0.001). Conclusions One-month survival with favorable neurological outcome in OHCA patients occurring at night remains to be significantly worse than those occurring during daytime, even improved by the periods during daytime. CPR training for the family members should be more expanded and strengthened against the night time imperfection.

Objective: The study aimed to measure the success rate of pre-hospital tracheal intubation (TI) and supraglottic airway devices (SADs) performed by paramedics for adult patients and to assess the perception of paramedics of advanced airway management.Method: The study consisted of two phases: phase 1 was a retrospective analysis to assess the TI and SADs’ success rates when applied by paramedics for adult patients aged >14 years from 2012 to 2017, and phase 2 was a distributed questionnaire to assess paramedics’ perception of advanced airway management.Result: In phase 1, 24 patients met our inclusion criteria. Sixteen (67%) patients had TI, of whom five had failed TI but then were successfully managed using SADs. The TI success rate was 69% from the first two attempts compared to SADs (100% from first attempt). In phase 2, 63/90 (70%) paramedics responded to the questionnaire, of whom 60 (95%) completed it. Forty-eight (80%) paramedics classified themselves to be moderately or very competent with advanced airway management. However, most of them (80%) performed only 1‐5 TIs or SADs a year.Conclusion: Hospital-based paramedics (i.e. paramedics who are working at hospitals and not in the ambulance service, and who mostly respond to small restricted areas in Saudi Arabia) handled few patients requiring advanced airway management and had a higher competency level with SADs than with TI. The study findings could be impacted by the low sample size. Future research is needed on the success rate and impact on outcomes of using pre-hospital advanced airway management, and on the challenges of mechanical ventilation use during interfacility transfer.
