Abstract Introduction: The evaluation of extracorporeal membrane oxygenation-related nosocomial infection (ECMO-related NI) in a homogeneous cohort remains scarce. This study analyzed ECMO-related NI in adult patients who have undergone cardiac surgery. Methods: From January 2012 to December 2017, 322 adult patients who have received ECMO support after cardiac surgery were divided into the infection group (n=131) and the non-infection group (n=191). ECMO-related NI was evaluated according to demographic data, surgical procedures, and ECMO parameters. Results: The incidence of ECMO-related NI was 85.4 cases per 1000 ECMO days. Acinetobacter baumannii was the most common pathogen causing blood stream infection and respiratory tract infection. Prolonged duration of surgery (P=0.042) and cardiopulmonary bypass assist (P=0.044) increased the risk of ECMO-related NI. Body mass index (odds ratio [OR]: 1.077; 95% confidence interval [CI]: 1.004-1.156; P=0.039) and duration of ECMO support (OR: 1.006; 95% CI: 1.003-1.009; P=0.0001) were the independent risk factors for ECMO-related NI. Duration of ECMO support > 144 hours (OR: 2.460; 95% CI: 1.155-7.238; P<0.0001) and ECMO-related NI (OR: 3.726; 95% CI: 1.274-10.895; P=0.016) increased significantly the risk of in-hospital death. Conclusion: Prolonged duration of ECMO support was an independent risk factor for NI. Surgical correcting latent causes of cardiopulmonary failure and shortening duration of ECMO whenever possible would reduce susceptibility to NI.
