Abstract Background The effects of prehospital epinephrine administration in combination with the quality of cardiopulmonary resuscitation (CPR) on neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm remains unclear. Purpose This study aimed to elucidate the effects of prehospital epinephrine administration in combination with the quality of CPR on neurologically intact survival in OHCA patients with non-shockable rhythm. Methods We analysed 118,732 adult OHCA patients with non-shockable rhythm from the All-Japan OHCA registry between 2011 and 2016 (29,989 emergency medical service [EMS]-witnessed arrests with EMS-initiated CPR [high-quality CPR] and 88,743 bystander-witnessed arrests with bystander-initiated CPR continued by EMS providers [low-quality CPR]). Patients who achieved prehospital return of spontaneous circulation without prehospital epinephrine administration were excluded. The primary outcome measure was 1-month neurologically intact survival (cerebral performance category 1 or 2; CPC 1–2). Time from collapse to prehospital epinephrine administration for patients with prehospital epinephrine administration, or to hospital arrival for patients without prehospital epinephrine administration was calculated and adjusted collectively in multivariate logistic regression analysis for 1-month CPC 1–2. Results Multivariate logistic regression analysis revealed that the time from collapse to prehospital epinephrine administration or to hospital arrival was negatively associated with 1-month CPC 1–2 (adjusted odds ratio [OR] 0.95 per 1-minute increment, 95% confidence interval [CI] 0.94–0.96). Compared with bystander-witnessed arrests without prehospital epinephrine administration, EMS-witnessed arrests with or without prehospital epinephrine administration were significantly associated with increased chances of 1-month CPC 1–2 (adjusted OR 2.04, 95% CI 1.50–2.75 and adjusted OR 1.97, 95% CI 1.57–2.48, respectively). Prehospital epinephrine administration was significantly associated with an increased chance of 1-month CPC 1–2 among bystander-witnessed arrests (adjusted OR 1.57, 95% CI 1.24–1.98), but not among EMS-witnessed arrests. EMS-witnessed arrests without prehospital epinephrine administration were significantly associated with an increased chance of 1-month CPC 1–2 compared with bystander-witnessed arrests with prehospital epinephrine administration (adjusted OR 1.26, 95% CI 1.01–1.56). Conclusions High-quality CPR is crucial for increasing neurologically intact survival in OHCA patients with non-shockable rhythm. The additional beneficial effects of prehospital epinephrine administration were observed only among OHCA patients with low-quality CPR.

Introduction: While effective for out-of-hospital cardiac arrest, therapeutic hypothermia can be difficult to timely implement clinically. No drugs exist for improving neurologically intact survival. We have developed a novel peptide (TAT-PHLPP) that inhibits PH domain and Leucine rich repeat Protein Phosphatases (PHLPP), leading to Akt activation and mimicking of the protective effects of therapeutic hypothermia without the need of physical cooling. Hypothesis: We hypothesize that when administered intravenously during CPR, TAT-PHLPP improves neurologically intact survival. Methods: We conducted parallel studies in mouse and swine models. In C57BL6 mice (n = 72), we induced a 8 or 12-min asystolic cardiac arrest with KCl, followed by initiation of CPR and blinded randomized administration of TAT-PHLPP (7.5 mg/kg) or saline placebo. The primary outcomes were 4-h and 5-day survival, mean arterial blood pressure (MAP) and cerebral blood flow (CBF). We assessed PHLPP-NHERF1 binding and glucose utilization (via pyruvate dehydrogenase (PDH) phosphorylation and ATP generation). In 16 swine, we induced 5 min of VF followed by ACLS with vest CPR and administered two doses of TAT-PHLPP or saline. Survival (24 h) and neurological function were assessed. Plasma biomarkers taurine and glutamate levels in mice were measured and validated in CA patients (n=68) with a shockable rhythm at the time of hospital arrival, 6, 24, 48, and 72 h post-hospital arrival. Results: In mice, compared to saline, TAT-PHLPP significantly improved 4-h and 5-day survival, increased post-ROSC MAP and CBF, inhibited PHLPP-NHERF1 binding, increased p-Akt, decreased p-PDH (increased activity) at 15 min post-ROSC, enhanced ATP generation in both heart and brain, and reduced plasma taurine and glutamate levels. In swine, TAT-PHLPP improved 24 h neurologically intact survival (1/9 in control vs. 6/7 with peptide, p < 0.01). In patients, taurine levels were higher in non-survivors (n=44) than survivors (n=24) at 6 h of post-hospital arrival (65.9 ± 34.8 vs. 45.6 ±23.7, p< 0.001). Conclusions: TAT-PHLPP has high translational potential as a first-of-class biologic treatment to reproduce critical outcomes of therapeutic hypothermia and improve cardiac arrest survival.

Hospital Cardiac Arrest

Therapeutic hypothermia in selected patients surviving sudden out-of-hospital cardiac arrest can significantly improve rates of long-term survival and is considered as one of the most important clinical advancements in the science of resuscitation. Since 2003 the American Heart Association/International Liaison Committee on Resuscitation guidelines endorsed the use of hypothermic therapies as standard care for patients suffering from cardiac arrest while in 2005 additional inclusion and exclusion criteria were applied to patients experiencing in or out-of-hospital cardiac arrest with an initial shockable and non shockable rhythm. The goals of treatment in 2015 include achieving targeted temperature as quickly as possible with immediate initiation of cooling methods accompanied with supportive therapy and controlled rewarming.

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.

ObjectiveThe purpose of this study was to assess the trends in outcomes of out-of-hospital cardiac arrest (OHCA) in Beijing over 5 years.DesignCross-sectional study.MethodsAdult patients with OHCA of all aetiologies who were treated by the Beijing emergency medical service (EMS) between January 2013 and December 2017 were analysed. Data were collected using the Utstein Style. Cases were followed up for 1 year. Descriptive statistics were used to characterise the sample and logistic regression was performed.ResultsOverall, 5016 patients with OHCA underwent attempted resuscitation by the EMS in urban areas of Beijing during the study period. Survival to hospital discharge was 1.2% in 2013 and 1.6% in 2017 (adjusted rate ratio=1.0, p for trend=0.60). Survival to admission and neurological outcome at discharge did not significantly improve from 2013 to 2017. Patient characteristics and the aetiology and location of cardiac arrest were consistent, but there was a decrease in the initial shockable rhythm (from 6.5% to 5.6%) over the 5 years. The rate of bystander cardiopulmonary resuscitation (CPR) increased steadily over the years (from 10.4% to 19.4%).ConclusionSurvival after OHCA in urban areas of Beijing did not improve significantly over 5 years, with long-term survival being unchanged, although the rate of bystander CPR increased steadily, which enhanced the outcomes of patients who underwent bystander CPR.
