Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) is a promising treatment for refractory out-of-hospital cardiac arrest (OHCA). Most studies evaluating the effectiveness of ECPR include patients with an initial shockable rhythm. However, the effectiveness of ECPR for patients with an initial non-shockable rhythm remains unknown. This retrospective single-center study aimed to evaluate the effectiveness of ECPR for patients with an initial non-shockable rhythm, with reference to the outcomes of OHCA patients with an initial shockable rhythm. Methods Adult OHCA patients treated with ECPR at our center during 2011–2018 were included in the study. Patients were classified into the initial shockable rhythm group and the non-shockable rhythm group. The primary outcome was the cerebral performance category (CPC) scale score at hospital discharge. A CPC score of 1 or 2 was defined as a good outcome. Results In total, 186 patients were eligible. Among them, 124 had an initial shockable rhythm and 62 had an initial non-shockable rhythm. Among all patients, 158 (85%) were male, with a median age of 59 (interquartile range [IQR], 48–65) years, and the median low flow time was 41 (IQR, 33–48) min. Collapse was witnessed in 169 (91%) patients, and 36 (19%) achieved return of spontaneous circulation (ROSC) transiently. Proportion of female patients, presence of bystander cardiopulmonary resuscitation, and collapse after the arrival of emergency medical service personnel were significantly higher in the non-shockable rhythm group. The rate of good outcomes at hospital discharge was not significantly different between the shockable and non-shockable groups (19% vs. 16%, p=0.69). Initial shockable rhythm was not significantly associated with good outcome after controlling for potential confounders (adjusted odds ratio 1.58, 95% confidence interval: 0.66–3.81, p=0.31). In the non-shockable group, patients with good outcomes had a higher rate of transient ROSC, and pulmonary embolism was the leading etiology. Conclusions The outcomes of patients with an initial non-shockable rhythm are comparable with those having an initial shockable rhythm. OHCA patients with an initial non-shockable rhythm could be candidates for ECPR, if they are presumed to have reversible etiology and potential for good neurological recovery.

Background: The proper timing of introducing extracorporeal cardiopulmonary resuscitation (ECPR) in patients with out-of-hospital cardiac arrest (OHCA) due to acute coronary syndrome (ACS) has yet to be well-established. Hypothesis: The interval of start of ECPR from cardiac arrest is one of predictors of short-term survival in these particularly ill patients. Methods: Between June 2014 and December 2015, we enrolled a total of 13,491 Japanese OHCA patients who were transported to hospitals in a multicenter, prospective fashion (JAAM-OHCA registry). Following exclusion criteria, 72 patients with OHCA due to ACS who were introduced ECPR until return of spontaneous circulation and underwent emergent PCI and target temperature management were eligible for this study (median 59 years-old; 95% male). We investigated the relationship between the interval of start of ECPR or successfully coronary revascularization from cardiac arrest (collapse-to-ECPR or collapse-to-PCI interval) and the survival at 30 days. Results: Patients with survival at 30 days were 50% (n=36). Age, gender, the prevalence of patients with bystander CPR or ST-elevation and collapse-to-PCI interval were comparable between patients with/without survival. The survival patients had the higher prevalence of initial shockable rhythm and the shorter collapse-to-ECPR interval than those without survival (84 vs 57%, p=0.018; 50 vs 57 min, p=0.045). Receiver operating curve analysis indicated collapse-to-ECPR interval cutoff point of 50 min (area under the curve 0.66, sensitivity 54%, specificity 75%) and collapse-to-PCI interval cutoff point of 135 min (0.65, 64%, and 67%, respectively) for predicting survival at 30 days. Multivariate logistic regression analysis revealed initial shockable rhythm and collapse-to-ECPR interval as the independent predictors of survival (OR 5.71, p=0.015; OR 1.05, p=0.025, respectively). Conclusion: Collapse-to-ECPR interval is a significantly associated with 30 days survival in patients with OHCA due to ACS, while collapse-to-PCI interval is not independent predictor of survival in this study. These findings indicate that time management for start of ECPR from cardiac arrest can be essential for improving OHCA patients’ survival.

Central Cannulation

Introduction: Favorable survivorship after pediatric extracorporeal cardiopulmonary resuscitation (ECPR) may be limited by prolonged resuscitations. Surgical cannulation metrics for pediatric ECPR have not been widely reported by centers that use time interval benchmarks with a cardiovascular service responding to different hospital locations. Hypothesis: We hypothesize that survival is associated with resuscitation duration, and cannulation duration differs between peripheral and central approaches. Methods: This was a single-center retrospective study of patients 0-18 years with in-hospital ECPR between January 2015 and December 2020. Primary outcome was survival to hospital discharge. Secondary outcomes were odds of favorable neurologic outcome (dichotomized pediatric cerebral performance category), total resuscitation duration defined as cardiac arrest start to ECMO flow start (CA-ECMO), and cannulation duration. Non-parametric and regression methods were used. Results: Of the 92 events that met ECPR criteria, median weight and age were 4 months (IQR 1 month, 16 years) and 4.4 kg (range 1.9-133 kg). Cannulation occurred in the cardiac intensive care unit (ICU) (66%, 61 of 92), followed by operating room (13%, 12 of 92), pediatric ICU (12%, 11 of 92), and catheterization lab (9%, 8 of 92). Central cannulation was performed in 43% (40 of 92), and 21% (19 of 92) had open chests at the time of the event. Median duration of CA-ECMO was 35 min (IQR 26, 45 min); cannulation duration was 11 min (IQR 5, 16.5 min) for central compared to 18.5 min (IQR 12, 23 min) for peripheral approaches (P=0.01). Survival was 40% (37 of 92), and favorable neurologic outcome occurred in 38% (35 of 92). Survival (adjusted OR, 0.94; 95% CI 0.91-0.99, P=0.018) and favorable neurologic outcome (adjusted OR, 0.95; 95% CI 0.917-1.000, P=0.053) were associated with CA-ECMO duration after adjusting for cannulation approach, location, difficulty, shockable rhythm, and weight. Conclusion: In pediatric in-hospital ECPR, total CA-ECMO duration remains a key metric associated with patient outcomes. Central cannulation is faster than peripheral approaches. Since cannulation strategy alters CPR maneuvers, CPR effectiveness with each approach needs further study.

Introduction: For OHCA patients without ROSC under standard ALS, extracorporeal cardiopulmonary resuscitation (ECPR) was the only chance. However, ECPR was invasive and costed tremendous resources. This study aimed to analyze the predictor of favorable neurological outcome at hospital discharge (FO, cerebral performance category 1-2). Hypothesis: In OHCA patients receiving ECPR, shockable rhythm at hospital arrival could serve as predictor of FO. Method: This was a single center retrospective study which enrolled 126 OHCA patients receiving ECPR between January 2012 to December 2019. Primary outcome was FO at hospital discharge. Predictors of FO were assessed by multiple logistic regression. Patients with initial shockable rhythm were analyzed according to the cardiac rhythm at hospital arrival. Result: Among OHCA patients receiving ECPR, FO at hospital discharge was 21%. Certain variables were associated with FO: witnessed collapse (P=0.014), bystander CPR (P=0.05), shorter no flow time(P=0.008), and shockable rhythm at hospital arrival (78% vs. 49%;P=0.009). Initial shockable rhythm did not differ significantly (85% vs. 71% ;P=0.15). Multiple logistic regression showed that shockable rhythm at hospital arrival was the only predictor of FO (OR, 3.012; 95% CI, 1.06-8.53; P=0.038). Patients with initial shockable rhythm represented a heterogenous group. The group with shockable rhythm at hospital arrival had 30% of FO, which was significantly higher than 17% in PEA group, and 6% in asystole group (Graph 1). Patients who remained shockable had higher percentage of witnessed arrest, shorter arrest-hospital time, less metabolic disturbance, and hence higher percentage of FO. Conclusion: In OHCA patients receiving ECPR, shockable rhythm at hospital arrival could predict favorable neurological outcome at discharge more precisely than initial shockable rhythm. ECPR selection criteria should take the rhythm at hospital arrival into consideration.

Purpose: Extracorporeal cardiopulmonary resuscitation (ECPR) shows promising results in patients found in ventricular fibrillation (VF) without return of spontanous circulation (ROSC) on scene. Insight in rhythm at moment of transport and survival of potential ECPR patients could help to identify which patients should be transported for ECPR. Methods: Data of potential ECPR patients (shockable first rhythm, witnessed arrest, bystander CPR and age 18-70 year) transported without ROSC between 2012 and 2016 in the Amsterdam Resuscitation Study (ARREST) database were analyzed. Initial rhythm and rhythm at moment of transport was related to 30-day survival. Results: Of 5872 OHCA patients with attempted resuscitation, 649 (11%) were transported with ongoing CPR. Of these, 162 (25%) were considered potential ECPR patients and 153 cases with complete data were analysed. Thirteen of these 153 patients (9%) were alive at 30 days. At start of transport, 68 patients (44%) had VF/VT, 58 (38%) PEA and 27 (18%) asystole. Of these, 10, 2 and 1 patients survived, respectively (figure). 30-day survival of patients with a shockable rhythm at start of transport was significantly higher compared to non-shockable rhythms (15% vs 3%, p=0.014). During transport 10 of 153 patients (7%) achieved ROSC, and 3 patients (30%) survived. VF/VT at start of transport identified 10/13 (77%) of all survivors. In patients without ROSC at hospital arrival, VF/VT also resulted in the highest survival (13%). Conclusion: In ECPR candidate patients, a shockable rhythm at the moment of transport (44%) identified 77% of patients surviving 30 days.

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.
