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.

Hospital Cardiac Arrest

Background: Prolonged conventional cardiopulmonary resuscitation (C-CPR) is associated with a poor prognosis in out-of-hospital cardiac arrest (OHCA) patients. Extracorporeal cardiopulmonary resuscitation (E-CPR) has been utilized as a rescue strategy for patients with cardiac arrest unresponsive to C-CPR. However, the indication and optimal duration to switch from C-CPR to E-CPR are not well established. In addition, the opportunities to develop teamwork skills and expertise to mitigate risks are few. We thus developed the implementation protocol for the E-CPR simulation program, and investigated whether the faster deployment of extracorporeal membrane oxygenation (ECMO) improves the neurological outcome in patients with refractory OHCA. Methods: A total of 42 consecutive patients (age 58±16 years, male ratio 90%, and initial shockable rhythm 64%) received E-CPR (3% of OHCA) during the study period. Among them, 32 (76%) were deployed ECMO during the pre-intervention time period (Pre: from January 2012 to September 2017), whereas 10 (24%) were deployed during the post-intervention time period (Post: October 2017 to May 2019). We compared the door to E-CPR time, collapse to E-CPR time, 30-day mortality, and favorable neurological outcome (Cerebral Performance Categories 1, 2) between the two periods. Results: There was no significant difference in age, the rates of male sex and shockable rhythm, and the time form collapse to emergency room admission between the two periods. The door to E-CPR time and the collapse to E-CPR time were significantly shorter in the post-intervention period compared to the pre-intervention period (Pre: 39 min [IQR; 30-50] vs. Post: 29 min [IQR; 22-31]; P=0.007, Pre: 76 min [IQR; 58-87] vs. Post: 59 min [IQR; 44-68]; P=0.02, respectively). The 30-day mortality was similar between the two periods (Pre: 88% vs. Post: 80%; P=0.6). In contrast, the rate of favorable neurological outcome at the time of discharge was significantly higher in post-intervention period (Pre: 0% vs. Post: 20%; P=0.01) compared to the pre-intervention period. Conclusion: A comprehensive simulation-based training for E-CPR seems to improve the neurological outcome in patients with refractory OHCA patients.

Background: The 2015 CoSTR recommended that standard-dose epinephrine (SDE) was reasonable for patients with out-of-hospital cardiac arrest (OHCA) and extracorporeal cardiopulmonary resuscitation (ECPR) was reasonable rescue therapy for selected patients with ongoing cardiac arrest when initial conventional CPR was unsuccessful. We investigated the effect of prehospital SDE for patients who met the criteria of ECPR. Methods: From the All-Japan OHCA Utstein Registry between 2007 and 2015, we included 22,552 patients who met the criteria of ECPR of the SAVE-J study (age between 20 and 75, witnessed shockable OHCA, cardiac arrest on hospital arrival, cardiac etiology, and collapse-to-ECPR interval within 60 minutes). Study patients were divided into two groups according to prehospital SDE or not. Primary endpoint was favorable 30-day neurological outcome after OHCA. Results: Of the 22,552 study patients, 5,659 (25%) received prehospital SDE and 16,893 (75%) did not. The SDE group resulted in lower proportion of favorable 30-day neurological outcome than the no-SDE group (5.6% versus 8.4%, p<0.001) with longer collapse-to-hospital-arrival interval (36.7±9.8 min vs. 29.6±11.3 min, p<0.001). After adjustment for independent predictors of resuscitation, prehospital SDE did not impact on neurological benifit (adjusted OR,1.13; 95%CI,0.98-1.29), but the collapse-to-hospital-arrival interval was associated with neurological benefit (adjusted OR, 0.94; 95% CI, 0.93-0.95). In curve estimation of the SDE group, when collapse-to-hospital-arrival interval was delayed, proportion of the favorable neurological outcome decreased to about 25% at 1 minute and about 0% at 54 minutes (R=0.14). In the 274 patients undergoing ECPR of the SAVE-J study, however, it was about 43% at 1 minute and about 0% at 96 minutes (R=0.17). Conclusions: Prehospital SDE did not improve likelihood of favorable neurological outcome for patients who met the criteria of ECPR (age between 20 and 75, witnessed shockable OHCA, cardiac arrest on hospital arrival, cardiac etiology and collapse-to-ECPR interval within 60 minutes), because SED administration delayed the collapse-to-hospital-arrival interval which was closely related to the neurologically intact survival on ECPR.

Favorable Neurological Outcome

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.

Abstract Background The 2015 cardiopulmonary resuscitation (CPR) guidelines have stressed that high-quality CPR improves survival from cardiac arrest (CA). In particular, the guidelines recommended that it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min in adult CA patients. However, it is unknown whether the 2015 guidelines contributed to favorable neurological outcome in adult CA patients. The present study aimed to clarify the effects of the 2015 guidelines in adult CA patients, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital CA (OHCA). Methods From the data of this registry between 2011 and 2016, we included adult witnessed OHCA patients due to cardiac etiology, who had non-shockable rhythm as an initial rhythm. We excluded patients who received prehospital care in 2015 because it was difficult to distinguish prehospital care based on either 2010 CPR guidelines or 2015 CPR guidelines. We also excluded patients who received bystander CPR by citizens because we cannot assess the quality of bystander CPR in this registry. Study patients were divided into five groups based on different years (figure). The endpoint was the favorable neurological outcome at 30 days after OHCA. Potential confounding factors based on biological plausibility and previous studies were included in the multivariable logistic regression analysis. These variables included the age, sex (male, female), advanced airway or not, the administration of adrenaline or not, the administration of saline or not, instructed by dispatcher or not, and time interval from call EMS to scene. Results The figure showed favorable neurological outcomes at 30 days. In the multivariate analysis, the adjusted odds ratio for 30-day favorable neurological outcome in OHCA patients in 2016 as compared to in 2011 was 1.32 (95% CI: 1.04–1.68, p=0.022). On the other hands, there were no significant differences from 2011 to 2014. Conclusion In the OHCA patients with non-shockable rhythm, the 2015 guidelines were superior to the 2010 guidelines, in terms of neurological benefits.

Abstract Background The aim of this study was to investigate whether intermittent electroencephalography (EEG) could be used to predict neurological prognosis of patients who underwent extracorporeal cardiopulmonary resuscitation (ECPR). Methods This was a retrospective, single center, and observational study of adult patients who were evaluated by EEG scan within 96 hours after ECPR between February 2012 and December 2018. The primary endpoint was neurological status upon discharge from the hospital assessed with Cerebral Performance Categories (CPC) scale. Results Among 69 adult cardiac arrest patients who underwent ECPR, 32 (46.4%) patients survived until discharge from the hospital. Of these 32 survivors, 17 (24.6%) patients had favorable neurological outcomes (CPC score: 1 or 2). Sedatives or analgesics were used in 41 (59.4%) patients. Malignant EEG patterns were more common in patients with poor neurological outcome than in patients with favorable neurological outcome (73.1% vs. 5.9%, p < 0.001). All patients with highly malignant EEG patterns (43.5%) had poor neurological outcome. Moderately malignant EEG patterns were reported in 8 (11.6%) patients with poor neurological outcome and one (1.4%) patient with favorable neurological outcome. Benign EEG patterns were more common in patients with favorable neurological outcome than in patients with poor neurological outcome (94.1% vs. 26.9%, p < 0.001). In multivariable analysis, malignant EEG patterns (adjusted odd ratio [OR]: 53.26, 95% confidence interval [CI]: 5.956 – 476.249) and duration of cardiopulmonary resuscitation (adjusted OR: 1.07, 95% CI: 1.011 – 1.130) were significantly associated with poor neurological outcomes in patients who underwent ECPR (Hosmer-Lemeshow Chi-squared = 7.84, df = 7, p = 0.347). Conclusions In this study, malignant EEG patterns within 96 hr after cardiac arrest were significantly associated with poor neurological outcomes in patients who underwent ECPR. Therefore, early intermittent EEG scan could be helpful for predicting neurological prognosis of post-cardiac arrest patients after 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.
