Propose: The aim of this retrospective study was to investigate the prognostic factors in extracorporeal cardiopulmonary resuscitation (ECPR) patients and to assess their accuracy as predictors of a favorable neurological outcome. Materials and methods: Between October 2009 and December 2017, we retrospectively analyzed witnessed out-ofhospital cardiac arrest patients who were admitted to our hospital and resuscitated with ECPR. We compared the baseline characteristics, pre-hospital clinical course, arrest causes, and blood samples on admission for the favorable and unfavorable outcome groups. Results: Among the 135 patients included, 22 (16%) had a favorable neurological outcome. Low-flow time was shorter (median 38 vs. 48 min, p <0.001) in the favorable neurological outcome group: in multiple logistic analyses, low-flow time was significantly associated with a favorable neurological outcome (odds ratio, 0.88; 95% confidence interval, 0.82-0.94). The area under the receiver-operating characteristic curve of low-flow time was 0.80 (95% confidence interval, 0.70-0.89), and the cut-off value of 58 min corresponded to a sensitivity of 0.25 and a specificity of 1.0. Conclusions: In ECPR patients, low-flow time was significantly associated with a favorable neurological outcome, and ECPR should be performed within 58 min of the low-flow time.
