BACKGROUND: Living-donor liver transplantation (LDLT) is a viable alternative to deceased-donor liver transplantation. Enhanced recovery after surgery protocols that include early extubation offer short-term benefits
however, the effect of immediate extubation in the operating room (OR) on long-term outcomes in patients undergoing LDLT remains unknown. We hypothesized that immediate OR extubation is associated with improved long-term outcomes in patients undergoing LDLT. METHODS: This retrospective cohort study included 205 patients who underwent LDLT. The patients were classified based on the extubation location as OREX (those extubated in the OR) or NOREX (those extubated in the intensive care unit [ICU]). The primary outcome was overall survival (OS), while secondary outcomes included ICU stay, hospital stay duration, and various postoperative outcomes. RESULTS: Among the 205 patients, 98 (47.8%) underwent extubation in the OR after LDLT. Univariate analysis revealed that OR extubation did not significantly affect OS (hazard ratio [HR]: 0.50, 95% confidence interval [CI]: 0.24-1.05
P = 0.066). Furthermore, multivariate analysis revealed no statistically significant association between OR extubation and OS (HR: 0.79, 95% CI: 0.35-1.80
P = 0.580). However, OR extubation was significantly associated with a lower incidence of 30-day composite complications and shorter ICU and hospital stays. Multivariate analysis indicated that higher preoperative platelet counts, increased serum creatinine levels, and a longer surgery duration were associated with poorer OS. CONCLUSIONS: Immediate OR extubation following LDLT surgery was associated with fewer 30-day composite complications and shorter ICU and hospital stays
however, it did not significantly improve OS compared with ICU extubation.
