Background
Retrospective studies indicate that acetaminophen iv administration reduces hospital length of stay (LoS) and opiate consumption in patients undergoing bariatric surgery.
Objective
This study sought to determine whether using acetaminophen iv in morbidly obese subjects undergoing sleeve gastrectomy decreased LoS and total hospital charges as compared to patients receiving saline placebo.
Setting
Single-center university hospital
Methods
Using a randomized, double-blind, placebo-controlled design, subjects were assigned to receive either acetaminophen iv (group A) or saline placebo iv (group P). Data were collected between Jan 1 and Dec 31, 2016. Group A received acetaminophen every 6 h for a total of four doses. The first dose was administered following the induction of general anesthesia; group P received saline iv on the same schedule. Anesthetic management and prophylactic antiemetic regimen were standardized in all subjects. Postoperative pain management consisted of hydromorphone via patient-controlled infusion pump. Primary outcomes include hospital LoS and associated hospital costs. Secondary outcomes include patient satisfaction and postoperative nausea and pain scores.
Results
Subject demographics (n = 127) and intraoperative management were similar in the two groups. Across all subjects, median hospital LoS in group A (n = 63) was 1.87 vs. 1.97 days in group P (n = 64) (p = 0.03, Wilcoxon rank-sum test). Postoperatively, daily quality-of-recovery (QoR-15) scores, narcotic consumption, and the use of rescue antiemetics were not significantly different between groups. Median hospital costs were as follows: group A, $12,885 vs. group P, $12,977 (n = 64).
Conclusions
Acetaminophen iv may reduce hospital LoS in subjects undergoing sleeve gastrectomy.
