Outcomes of noncardiotomy patients requiring postoperative extracorporeal membrane oxygenation

Background The use of extracorporeal membrane oxygenation (ECMO) in the postoperative period has expanded to include a variety of noncardiotomy procedures. It is important to investigate outcomes for this uniquely ill subset of patients as currently published data on this subject is limited. Methods All ECMO events at our institution from 2006 to 2017 were retrospectively considered. Patients were grouped into a postoperative noncardiotomy (PNC) cohort (n = 20) and a larger control cohort (n = 220). For additional analysis, the PNC cohort was further split into a liver transplant group (n = 4) and thoracic surgery group (n = 10). Basic demographics, medical history, type of operation performed, indication for support, and survival data were collected on all patients. Appropriate statistical analyses were performed and a P
