Immediate extubation following pediatric liver transplantation.

BACKGROUND

Immediate extubation (IE) following pediatric liver transplantation is being increasingly performed. The aim of this study was to characterize the rate of IE at our institution and identify recipient factors predictive of IE.

METHODS

All pediatric liver transplants performed at our institution between January 1, 2015 and December 31, 2020 were reviewed. Retransplants and multi-organ transplants were excluded. IE was defined as extubation in the operating room following transplant. Backward stepwise logistic regression at a p-value threshold of .05 was performed to identify variables associated with IE.

RESULTS

IE was achieved in 58 (72%) of the 81 pediatric liver transplants. The IE cohort had significantly shorter ICU length of stay and overall hospital length of stay, though IE was not an independent predictor of posttransplant length of stay. Age <2 years, preoperative mechanical ventilation, and total intraoperative epinephrine and dopamine infusion requirements were significant, independent risk factors against IE. This multivariable model was highly predictive of IE (area under the curve = 0.89).

CONCLUSIONS

We describe the highest rate of IE postpediatric liver transplantation that has been reported to date and identified significant risk factors against successful IE.
