Abstract:
Objectives:To analyze the clinical characteristics of patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) and identify the risk factors for death.Methods:The clinical data of 60 patients undergoing ECPR admitted to our hospital and Hangzhou First People's Hospital from September 2014 to September 2019 were retrospectively analyzed. The patients were divided into the survival group and the death group. The clinical data of the two groups were compared to explore the risk factors related to death. COX regression analysis was used to identify the risk factors for death.Results:Sixty patients undergoing ECPR were included in our study, of them, 16 (26.7%) cases were out-of-hospital cardiac arrest (OHCA) and 44 (73.3%) cases were in-hospital cardiac arrest (IHCA). The mortality of OHCA patients was higher than that of IHCA patients (87.5% vs. 56.89%, P < 0.05), and the duration from CPR to ECMO installation in the death group was longer than that in the survival group [(105.4±105.1) min vs. (53.0±28.5) min, P < 0.05]. Compared with the survival group, patients in the death group had higher troponin and glutamic oxalacetic transaminase and lower PH and lactate ( P < 0.05). The median survival time of the 60 patients was 42 days. Out-of-hospital cardiac arrest, high SOFA score before ECMO, high-dose norepinephrine, pulmonary infection during ECMO support and long ECMO support time were independent predictors of patients’ death. Conclusions:Risk factors associated with patients’ death undergoing ECPR are out-of-hospital cardiac arrest, high SOFA score before ECMO, high-dose norepinephrine, long duration from CPR to ECMO installation, pulmonary infection during ECMO support and long ECMO support time.
