Abstract
Objective: To evaluate the resuscitation efficacy of extracorporeal membrane oxygenation (ECMO) for non-postcardiotomy cardiac arrest adult patients post failed conventional cardiopulmonary resuscitation (CCPR). Methods: We retrospectively analyzed the clinical data of a total of 25 consecutive adults who suffered from non-postcardiotomy cardiac arrest and were treated with ECMO post failed CCPR in our hospital between January 2010 and January 2015. Inclusion criteria included: 18 to 75 years old; the duration from cardiac arrest to CCPR initiation<5 minutes; no recovery of spontaneous circulation within 10 min after implementation of standard CCPR, and the length of CCPR <90 minutes. Patients were divided into non-survival group (18 cases) and survival group (7 cases) based on their in-hospital outcome and the clinical characteristics were compared. Related factors of survival to discharge were analyzed by Spearman correlation analysis. Results: Majority of patients (84.0%(21/25)) developed cardiac arrest in our hospital, mostly due to acute myocardial infarction (80.0%(20/25)). The mean duration of CCPR prior to ECMO support was 40.0 (27.5, 72.0) minutes. The mean duration of ECMO support was 72.0 (47.5, 128.3) hours and 9 patients (36.0%) were successfully weaned. Intensive care unit stay was significantly shorter (3.0(1.8-7.8)days vs.16.0(11.0-37.0) days, P<0.01), mean blood pressure at 24 and 48 hours after ECMO initiation was significantly lower ((73.2±20.1)mmHg(1 mmHg=0.133 kPa) vs. (91.1±20.4)mmHg, P<0.05; (63.0±16.7)mmHg vs. (86.6±18.0 mmHg), P<0.05, respectively) and platelet count at 72 hours after extracorporeal support was significantly lower ((57.0±30.1)×109/L vs. (97.3±31.5)×109/L, P<0.05) in the non-survivor group than in survival group. Spearman correlation analysis demonstrated that mean arterial pressure at 24 hours (r=0.427, P<0.05) and 48 hours(r=0.558, P<0.05), and platelet count at 72 hours after extracorporeal support (r=0.577, P<0.05) were significantly correlated with survival to discharge. Conclusion: ECMO can be used as an effective alternative for refractory cardiac arrest in non-postcardiotomy adult patients.
