Abstract
OBJECTIVES
Prolonged tracheal intubation and mechanical ventilation after liver transplant increase postoperative complications. Hence, timely extubation should be considered; however, a standard clinical criteria set or scoring system to select patients has not been established for early extubation after livertransplant.We investigated the factors that affect early extubation to design a predictive scoring system for early extubation.
MATERIALS AND METHODS
This study is a case-control study of adult liver transplant patients. Preoperative, intraoperative, and postoperative clinical data were collected. Early extubation was defined as tracheal extubation immediately or up to 6 hours posttransplant. The variables were compared between the early extubation group and the delayed extubation (>6 hours) group.
RESULTS
Our study enrolled 237 patients; among them, 57 patients (24%) were in the early extubation group, and 180 (76%) were in the delayed extubation group. Multiple logistic regression analysis showed that postoperative base excess level at admission to the intensive care unit, number of units of packed red blood cells transfused during surgery, urine volume, and excess base level 6 hours after surgery were the main predictors of successful early extubation.
CONCLUSIONS
The initial base excess level at the entrance to the intensive care unit(postsurgery) and 6 hours after surgery, packed red blood cell volume transfused during surgery, and urine volume 6 hours after surgery are the main predictors for a successful early tracheal extubation.These factors are considered for the Shiraz Extubation Predictor formula.
