Smith NK, Zerillo J, Kim S, et al. - Researchers aimed at determining the rate of intraoperative cardiac arrest (ICA), associated risk factors, and outcomes in orthotopic liver transplantation (OLT) via a retrospective, observational study of 5,296 adult liver transplant recipients (18–80 years old) utilizing data from seven academic medical centers. Among these patients, 196 cases developed ICA (3.7% 95% confidence interval [CI], 3.2–4.2) and 62 patients died (1.2%). The previously identified risk factors for ICA including BMI, Model for End-Stage Liver Disease score, postreperfusion syndrome, and reoperation were confirmed and new risk factors including living donor and length of surgery were identified in this multicenter retrospective cohort. Despite its rare occurrence, ICA is linked with high intraoperative mortality
