Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). Despite growing interest in and a growing body of literature on ECPR for refractory OHCA, robust evidence on patient eligibility is still lacking. Purpose To describe the survival, neurological outcome, and adherence to the national consensus with respect to use of ECPR for OHCA, and to identify factors associated with outcome. Methods Retrospective, observational cohort study of patients who underwent ECPR for OHCA at four cardiac arrest centres. Binary logistic regression and Kaplan-Meier survival curves were performed to assess association with 30-day mortality. Results A total of 259 patients receiving ECPR for OHCA between July 2011 and December 2020 were included in the study. Thirty-day survival was 26% and a good neurological outcome Cerebral Performance Category (CPC) 1–2 was observed in 94% of patients at discharge. Strict adherence to the national consensus showed a 30-day survival rate of 30%. Adding one or more of the following criteria to the national consensus: signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow <100 minutes, pH >6.8 and lactate <15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified initial presenting rhythm with asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (PEA) (RR 1.20, 95% CI 1.03–1.41), initial pH <6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels >15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had threefold higher survival rate than patients without signs of life (45% versus 13%, p<0.001) Conclusion A high survival rate with a good neurological outcome was observed in this population of patients treated with ECPR for OHCA. Signs of life during CPR may aid the decision-making in the selection of appropriate candidates. Stringent patient selection for ECPR may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors, why optimization of the selection criteria is still necessary.

Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to to describe the gradual implementation, survival and adherence to the national consensus with respect to use of ECPR for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving ECPR for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan-Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day survival. Results A total of 259 patients were included in the study. Thirty-day survival was 26% and a good neurological outcome (Glasgow-Pittsburgh Cerebral Performance Categories (CPC) (CPC 1–2)) was observed in 94% of patients at discharge. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 minutes, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had a threefold higher survival rate compared to patients without signs of life (45% versus 13%, p < 0.001). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with ECPR for OHCA.

Abstract Background Mechanical circulatory support (MCS) with either extracorporeal membrane oxygenation or Impella has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to describe the gradual implementation, survival and adherence to the national consensus with respect to use of MCS for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving MCS for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan–Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day mortality. Results A total of 259 patients were included in the study. Thirty-day survival was 26%. Sixty-five (25%) survived to hospital discharge and a good neurological outcome (Glasgow–Pittsburgh Cerebral Performance Categories 1–2) was observed in 94% of these patients. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 min, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had reduced risk of 30-day mortality (RR 0.63, 95% CI 0.52–0.76). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with MCS for OHCA. Stringent patient selection for MCS may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors.

Introduction: This study aimed to compare the effect of audio-instructed dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) and video-instructed DA-CPR on resuscitation outcome after out-of-hospital cardiac arrest (OHCA) in the real world. Methods: A cross-sectional study was conducted for resuscitation-attempted adult OHCAs of 2017 in Seoul, Korea. Seoul implemented video-instructed DA-CPR program in 2017. According to the protocol, when dispatcher detected OHCA, they checked two condition: 1) more than two bystanders were in the scene, 2) they could handle a video-call. If both conditions were met, dispatcher initiated the CPR instruction and called back a video-call to the caller for instructing CPR via video (video group). Unless, standard audio-instructed DA-CPR was provided (audio group). The primary outcome was survival to discharge. The secondary outcome was good neurological outcome at hospital discharge. The tertiary outcome was early instruction time interval (ITI, time from call to the initiation of CPR instruction≤ 90 seconds). The study outcomes were compared between audio and video group. A multivariable logistic regression analysis was performed and adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were calculated adjusting for potential confounders. Propensity score matching (PSM) method was used to increase comparability of two groups and same logistic regression model was analyzed for the PSM population. Results: A total of 1,720 eligible OHCA cases (1,489 in audio and 231 in video group) were evaluated. The median seconds of ITI was 136 seconds in audio group and 122 seconds in the video group (p=0.12). Survival to discharge was 8.9% in audio group and 14.3% in video group (p<0.01). Good neurological outcome was 5.8% in audio group and 10.4% in video group (p<0.01). Compared with audio group, the AORs (95% CIs) for survival to discharge, good neurological outcome and early ITI of the video group were 1.20 (0.74 to 1.94), 1.28 (0.73 to 2.26) and 1.00 (0.70 t0 1.43), respectively. PSM population showed similar results with original population. Conclusion: Compared with audio-instructed DA-CPR, video-instructed DA-CPR was not associated with survival improvement in the observational study.

Background Little is known about the association between prehospital cardiopulmonary resuscitation duration for adults with out-of-hospital cardiac arrest and outcome by the location of arrests. This study aimed to investigate the association between prehospital cardiopulmonary resuscitation duration and one-month survival with favourable neurological outcome. Methods We analysed 276,391 adults aged 18 years and older with out-of-hospital cardiac arrest of medical origin before emergency medical service arrival. Prehospital cardiopulmonary resuscitation duration was defined as the time from emergency medical service-initiated cardiopulmonary resuscitation to prehospital return of spontaneous circulation or to hospital arrival. The primary outcome was one-month survival with favourable neurological outcome (cerebral performance category 1 or 2). The association between prehospital cardiopulmonary resuscitation duration and favourable neurological outcome was assessed using univariable and multivariable logistic regression analyses. Results The proportion of favourable neurological outcomes was 2.3% in total, 7.6% in public locations, 1.5% in residential locations and 0.7% in nursing homes ( P < 0.001). In univariable and multivariable logistic regression analyses, longer prehospital cardiopulmonary resuscitation duration was associated with poor neurological outcome, regardless of arrest location ( P for trend < 0.001). Patients with shockable rhythm in both public and residential locations had better neurological outcome than those in nursing homes at any time point, and residential and public locations had a similar neurological outcome tendency among patients with shockable rhythm. Conclusions Longer prehospital cardiopulmonary resuscitation duration was independently associated with a lower proportion of patients with favourable neurological outcomes. Moreover, the association between prehospital cardiopulmonary resuscitation duration and neurological outcome differed according to the location of arrest and the first documented rhythm.

Abstract Background Refractory cardiac arrest (CA), as defined by the absence of a return of spontaneous circulation (ROSC) is associated with poor prognosis. Current guidelines advocate the use of extracorporeal cardiopulmonary resuscitation (ECPR) for selected patients with CA. Although previous studies have reported the association of survival with some prognostic factors such as age, bystander CPR attempt, low-flow duration or lactate serum level, the impact of the evaluation of coronary artery by coronary angiography (CAG) and the revascularization of coronary artery stenosis have not been sufficiently elucidated. Purpose We sought to investigate impact of the CAG and the revascularization of coronary artery stenosis to predict mortality and neurological outcome at 30 days in out-of-hospital CA (OHCA) patients resuscitated by ECPR. Methods 1382 out-of-hospital cardiac arrest patients were transferred to our critical care center, of which 899 patients with refractory CA at the emergency department were extracted from the institutional consecutive database between January 2015 and December 2018. Among those patients, we performed ECPR for 85 patients, who were successfully resuscitated. To predict mortality in hospital and neurological outcome at 30 days, we investigated basic patients' characteristics, pre-hospital information, and post-hospital care including CAG and coronary revascularization. Results Among those who had first resuscitated by ECPR, 20 patients (23.5%) survived and 10 patients (11.8%) achieved good neurological outcome (cerebral-performance-category (CPC) =1 or 2) at 30 days. We performed CAG for 40 patients (47.1%) and revascularization by percutaneous coronary intervention for 25 patients (29.4%). Younger age (P=0.037), CAG (P=0.001), PCI (P=0.001), and hypothermia therapy (P<0.001) were associated with low mortality. In the multivariate analysis, age (Odds ratio (OR) 0.95; 95% confidence interval (CI) 0.91–0.99; P=0.0025), PCI (OR 4.5; 95% CI 1.15–17.6; P=0.031), and hypothermia therapy (OR 13.7; 95% CI 1.52–124; P=0.020) were independent predictors of 30-days survival. Without diabetes mellitus (P=0.024), CAG (P<0.001), PCI (P=0.006), and hypothermia therapy (P=0.038) were associated with good neurological outcome. PCI (OR 7.39; 95% CI 1.73–31.6; P<0.001) was independently predictive for good neurological outcome. Conclusions Successful PCI was an independent predictor of 30-days survival and good neurological outcome in OHCA patients who were resuscitated by ECPR.

Purpose: Targeted temperature management (TTM) is a standard of care in patients after cardiac arrest for neuroprotection. Currently, the effectiveness and efficacy of TTM after extracorporeal cardiopulmonary resuscitation (ECPR) is unknown. We aimed to compare neurological and survival outcomes between TTM vs non-TTM in patients undergoing ECPR for refractory cardiac arrest. Methods: We searched PubMed and 5 other databases for randomized controlled trials and observational studies reporting neurological outcomes or survival in adult patients undergoing ECPR with or without TTM. Good neurological outcome was defined as cerebral performance category <3. Two independent reviewers extracted the data. Random-effects meta-analyses were used to pool data. Results: We included 35 studies (n = 2,643) with the median age of 56 years (interquartile range [IQR]: 52-59). The median time from collapse to ECMO cannulation was 58 minutes (IQR: 49-82) and the median ECMO duration was 3 days (IQR: 2.0-4.1). Of 2,643, 1,329 (50.3%) patients received TTM and 1,314 (49.7%) did not. There was no difference in the frequency of good neurological outcome at any time between TTM (29%, 95% confidence interval [CI]: 23%-36%) vs. without TTM (19%, 95% CI: 9%-31%) in patients with ECPR ( P = 0.09). Similarly, there was no difference in overall survival between patients with TTM (30%, 95% CI: 22%-39%) vs. without TTM (24%, 95% CI: 14%-34%) ( P = 0.31). A cumulative meta-analysis by publication year showed improved neurological and survival outcomes over time. Conclusions: Among ECPR patients, survival and neurological outcome were not different between those with TTM vs. without TTM. Our study suggests that neurological and survival outcome are improving over time as ECPR therapy is more widely used. Our results were limited by the heterogeneity of included studies and further research with granular temperature data is necessary to assess the benefit and risk of TTM in ECPR population.

Background: Impella CP is a left ventricular pump which may serve as a circulatory support during cardiopulmonary resuscitation (CPR) for cardiac arrest (CA). Nevertheless, the survival rate and factors associated with survival in patients undergoing Impella insertion during CPR for CA are unknown. Methods: We performed a retrospective multicenter international registry of patients undergoing Impella insertion during on-going CPR for in- or out-of-hospital CA. We recorded immediate and 30-day survival with and without neurologic impairment using the cerebral performance category score and evaluated the factors associated with survival. Results: Thirty-five patients had an Impella CP implanted during CPR for CA. Refractory ventricular arrhythmias were the most frequent initial rhythm (65.7%). In total, 65.7% of patients immediately survived. At 30 days, 45.7% of patients were still alive. The 30-day survival rate without neurological impairment was 37.1%. In univariate analysis, survival was associated with both an age < 75 years and a time from arrest to CPR ≤ 5 min (p = 0.035 and p = 0.008, respectively). Conclusions: In our multicenter registry, Impella CP insertion during ongoing CPR for CA was associated with a 37.1% rate of 30-day survival without neurological impairment. The factors associated with survival were a young age and a time from arrest to CPR ≤ 5 min.
