Abstract: Aim: Extracorporeal cardiopulmonary resuscitation (ECPR) has been shown to have survival benefit over conventional CPR (CCPR) in patients with in-hospital cardiac arrest of cardiac origin. We compared the survival of patients who had return of spontaneous beating (ROSB) after ECPR with the survival of those who had return of spontaneous circulation (ROSC) after conventional CPR. Methods: Propensity score-matched cohort of adults with in-hospital prolonged CPR (>10min) of cardiac origin in a university-affiliated tertiary extracorporeal resuscitation center were included in this study. Fifty-nine patients with ROSB after ECPR and 63 patients with sustained ROSC by CCPR were analyzed. Main outcome measures were survival at hospital discharge, 30 days, 6 months, and one year, and neurological outcome. Results: There was no statistical difference in survival to discharge (29.1% of ECPR responders vs. 22.2% of CCPR responders, p =0.394) and neurological outcome at discharge and one year later. In the propensity score-matched groups, 9 out of 27 ECPR patients survived to one month (33.3%) and 7 out of 27 CCPR patients survived (25.9%). Survival analysis showed no survival difference (HR: 0.856, p =0.634, 95% CI: 0.453–1.620) between the groups, either at 30 days or at the end of one year (HR: 0.602, p =0.093, 95% CI: 0.333–1.088). Conclusions: This study failed to demonstrate a survival difference between patients who had ROSB after institution of ECMO and those who had ROSC after conventional CPR. Further studies evaluating the role of ECMO in conventional CPR rescued patients are warranted. [Copyright &y& Elsevier]

The article reports on the results of a study of factors associated with survival among pediatric patients following extracorporeal cardiopulmonary resuscitation (ECPR) for in-hospital cardiac arrest. A description of the experimental set-up and measurement methods is presented. The study concluded that ECPR successfully rescued some pediatric patients who failed rescue with conventional in-hospital CPR.

: ObjectivesWe conducted this study to determine the result of prolonged cardiopulmonary resuscitation (CPR) with extracorporeal membrane oxygenation (ECMO) and the predictive factors for hospital discharge and ECMO weaning.: BackgroundProlonged CPR carries considerable associated mortality and morbidity. As yet, ECMO for prolonged CPR has no definite results. Only small groups of patients and no detailed analysis have been reported.: MethodsCandidates for ECMO resuscitation were patients in cardiac arrest receiving CPR >10 min without return of spontaneous circulation and no absolute contraindication. Venoarterial ECMO was set up during CPR. We reviewed the data of 57 prolonged CPR patients who received ECMO during CPR over a six-year period.: ResultsThe mean duration of CPR was 47.6 ± 13.4 min and that of ECMO was 96.1 ± 87.9 h. The rate of weaning was 66.7%, and the survival rate was 31.6%. Multiple-organ failure was the major reason for mortality, despite successful weaning. Among survivors, long-term follow-up revealed 88.9% survival, and only 5.6% had a severe neurologic deficit. The results indicate that a shorter CPR duration, postcardiotomy arrest, myocardial indicators, a hepatic indicator, and lactic acid are significantly correlated with both weaning and survival, whereas late damage (level on the third or seventh day of reperfusion) rather than initial damage (level on the first day) was more predictive of the results.: ConclusionsProlonged CPR rescue by ECMO provides an acceptable survival rate and outcome in survivors. Our results of the selected cases encourage further investigations of the wider application of ECMO in CPR. [Copyright &y& Elsevier]

Summary: Cardiopulmonary resuscitation (CPR) for 10–30min without return of spontaneous circulation is considered to have a grave prognosis. We report a 27-year-old woman who experienced in-hospital, witnessed cardiac arrest and underwent prolonged CPR with manual chest compressions for 280min. Adequate chest compression was monitored with femoral arterial pressure monitoring. During this time, she was alert and responsive. She was then supported with extracorporeal membrane oxygenation (ECMO) for 9 days without her heart beating. After combined heart and kidney transplantation, she recovered well with intact cerebral performance. This successful case report supports the endeavours for relentless CPR efforts.
