Abstract Introduction Quality improvement in the administration of extracorporeal cardiopulmonary resuscitation (ECPR) over time and its association with low-flow duration (LFD) and outcomes of cardiac arrest (CA) have been insufficiently investigated. In this study, we hypothesized that quality improvement in efforts to shorten the duration of initiating ECPR had decreased LFD over the last 15 years of experience at an academic tertiary care hospital, which in turn improved the outcomes of in-hospital CA (IHCA). Methods This was a single-center retrospective observational study of ECPR patients between January 2003 and December 2017. A rapid response system (RRS) and an extracorporeal membrane oxygenation (ECMO) program were initiated in 2011 and 2013. First, the association of LFD per minute with the 90-day mortality and neurological outcome was analyzed using multiple logistic regression analysis. Then, the temporal changes in LFD were investigated. Results Of 175 study subjects who received ECPR, 117 had IHCA. In the multivariate logistic regression, IHCA patients with shorter LFD experienced significantly increased 90-day survival and favorable neurological outcomes (LFD per minute, 90-day survival: odds ratio [OR] = 0.97, 95% confidence interval [CI] = 0.94–1.00, P = 0.032; 90-day favorable neurological outcome: OR = 0.97, 95% CI = 0.94–1.00, P = 0.049). In the study period, LFD significantly decreased over time (slope − 5.39 [min/3 years], P < 0.0001). Conclusion A shorter LFD was associated with increased 90-day survival and favorable neurological outcomes of IHCA patients who received ECPR. The quality improvement in administering ECPR over time, including the RRS program and the ECMO program, appeared to ameliorate clinical outcomes.

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 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.

Introduction: Previous studies have shown an association between hyperoxemia and mortality in out-of-hospital cardiac arrest (OHCA) patients after cardiopulmonary resuscitation (CPR); however, the evidence is lacking in patients receiving extracorporeal CPR (ECPR). Hypothesis: To test the hypothesis that hyperoxemia is associated with poor neurological outcome in patients treated by ECPR. Methods: The Japanese Association for Acute Medicine - OHCA (JAAM-OHCA) Registry is a multicenter, prospective, observational registry including 34,754 OHCA patients between 2014 and 2017. Patients who had been resuscitated and survived 24 hours after OHCA and had a PaO 2 levels above 60 mmHg were included. Eligible patients were divided into 2 groups by each 2 definition according to the PaO 2 levels measured from arterial blood gas analysis 24-h after the ECPR, (1) High-level of PaO 2 (H-PaO 2 , n=242) as PaO 2 ≥ 157 mmHg (median) and control (n=211) as 60 < PaO 2 < 157 mmHg, (2) hyperoxemia (HO, n=80) as PaO 2 ≥ 300 mmHg and control (n=373) as 60 < PaO 2 < 300 mmHg. The primary and secondary outcomes were the favorable neurological outcome, defined as Cerebral Performance Categories (CPC) Scale 1-2, and survival at 30 days after OHCA, respectively. Results: Out of 34,754 patients with OHCA, 453 patients with ECPR were included. The number of CPC 1-2 was significantly lower in the H-PaO 2 and HO group compared with each control group (H-PaO 2 : 17.4% vs. 33.2%; Odds ratio [OR] 0.42; 95% confidence interval [CI] 0.27-0.66; P<0.0001, HO: 8.8% vs. 28.2%; OR 0.24; 95% CI 0.11-0.55; P<0.001). The 30-day survival was lower in these high oxygen groups (H-PaO 2 : 39.3% vs. 57.4%; OR 0.48; 95% CI 0.33-0.70; P<0.0001, HO: 25.0% vs. 52.6%; OR 0.30; 95% CI 0.17-0.52; P<0.0001). After adjusting for potential confounders, the H-PaO 2 and HO were associated with unfavorable neurological outcomes (adjusted OR, H-PaO 2 ; 2.71; 95% CI 1.16-6.30; P=0.021, HO; 5.76; 95% CI 1.30-25.4; P=0.021). The H-PaO 2 and HO were also associated with poor 30-day survival (adjusted OR, H-PaO 2 ; 2.28; 95% CI 1.13-4.60; P=0.021, HO; 3.75; 95% CI 1.28-11.0; P=0.016). Conclusions: Hyperoxemia was associated with worse neurological outcomes in OHCA patients with ECPR.

Early Signs

Introduction: After 20 to 30 minutes of cardiopulmonary resuscitation (CPR) without return of spontaneous circulation (ROSC), cardiac arrest is considered as refractory (RCA). For RCA, extracorporeal CPR (ECPR) is one of the only treatments with a potential benefit on survival. Presence of gasping during CPR has been shown to be strongly associated with a favorable outcome. To our knowledge, signs of life during CPR (such as gasping, movements, pupillary response) has not been studied in the specific context of RCA treated with ECPR. Hypothesis: We assessed the relationship between survival with favorable neurologic outcomes and presence of early signs of life during or before CPR in RCA treated with ECPR. Methods: We carried out a multicenter observational study of patients with out-of-hospital RCA treated with ECPR in 3 cities in France. Primary outcome was favorable neurologic outcome at 30 days defined as CPC score ≤ 2. Signs of life were defined as gasping or recovery of normal breathing, any pupillary response or any movements during CPR. Patient selection for ECPR was decided according to french guidelines criteria such as initial rhythm, no-flow duration, expected transport time and EtCO2 > 10 mmHg. A logistic regression analysis was performed. P -values < 0.05 were considered statistically significant. Results: Overall, 437 patients treated with ECPR were included with 71 (16%) patients with CPC ≤ 2 at 30 days. Signs of life were observed in 261 (59%) patients, with 136 (31%) patients presenting gasping or respiratory movement, 155 (35%) a pupillary response, and 49 (11%) movements during CPR. Overall 63/261 (24.1%) patients with signs life survived with favorable neurologic outcome vs. 8/176 (4.5%) without signs of life, p<0.0001. In multivariate analysis, factors associated with favorable outcome were: signs of life during CPR (OR 11.0, 95%CI 3.7-32.5; p<0.001), first recorded rhythm VF/VT (OR 3.4, 95%CI 1.3-8.9; P=0.011), low-flow duration per min (OR 0.99, 95%CI 0.98-1.00; p=0.032). Conclusions: These results highlight the importance of signs of life before or during CPR on neurological outcomes for RCA treated with ECPR. These results could help select patients with good chance of survival in whom we should not give up resuscitation efforts too soon.

Abstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) performed at the emergency scene in out-of-hospital cardiac arrest (OHCA) can minimize low-flow time. Target temperature management (TTM) after cardiac arrest can improve neurological outcome. A combination of ECPR and TTM, both implemented as soon as possible on scene, appears to have promising results in OHCA. To date, it is still unknown whether the implementation of TTM and ECPR on scene affects the time course and value of neurological biomarkers. Methods 69 ECPR patients were examined in this study. Blood samples were collected between 1 and 72 h after ECPR and analyzed for S100, neuron-specific enolase (NSE), lactate, D-dimers and interleukin 6 (IL6). Cerebral performance category (CPC) scores were used to assess neurological outcome after ECPR upon hospital discharge. Resuscitation data were extracted from the Regensburg extracorporeal membrane oxygenation database and all data were analyzed by a statistician. The data were analyzed using non-parametric methods. Diagnostic accuracy of biomarkers was determined by area under the curve (AUC) analysis. Results were compared to the relevant literature. Results Non-hypoxic origin of cardiac arrest, manual chest compression until ECPR, a short low-flow time until ECPR initiation, low body mass index (BMI) and only a minimal need of extra-corporeal membrane oxygenation support were associated with a good neurological outcome after ECPR. Survivors with good neurological outcome had significantly lower lactate, IL6, D-dimer, and NSE values and demonstrated a rapid decrease in the initial S100 value compared to non-survivors. Conclusions A short low-flow time until ECPR initiation is important for a good neurological outcome. Hypoxia-induced cardiac arrest has a high mortality rate even when ECPR and TTM are performed at the emergency scene. ECPR patients with a higher BMI had a worse neurological outcome than patients with a normal BMI. The prognostic biomarkers S100, NSE, lactate, D-dimers and IL6 were reliable indicators of neurological outcome when ECPR and TTM were performed at the emergency scene.

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.
