While living donor liver transplantation (LDLT) serves as the predominant method of adult liver transplant (LT) in the Republic of Korea (ROK), it represents a minority of LT in the United States (US). A survey was conducted to gain insight into these nations' anesthetic management. An electronic questionnaire was distributed to directors of LT anesthesiology overseeing LDLT programs in both countries between May 2021 and October 2021. The response rate was 93.0% (100% [37/37] in the US and 80% [16/20] in the ROK). Both countries mainly adhered to deceased donor LT recipient management practices, including the frequency of routine pulmonary artery catheter use, transesophageal echocardiography, and point-of-care coagulation monitoring. Differences were observed in early extubation of recipients (US vs. ROK: 39.7%vs. 14.7% of all cases), participation in donor selection meetings (88.9% [32/36] vs. 6.3% [1/16], p < 0.0001), application of the Enhanced Recovery After Surgery donor protocol (69.4% [25/36] vs. 12.5% [2/16], p < 0.0001), and cell saver usage for donors (94.4% [34/36] vs. 18.8% [3/16], p < 0.0001). More ROK programs implemented simultaneous donor/recipient anesthesia supervision by a single anesthesiologist. Several important differences were identified between the US and the ROK in adult LDLT anesthetic management.
