ABSTRACT
BACKGROUND:
Pain management following major spine surgery requires high doses of opioids and is associated with a risk of opioid-induced constipation. Peripheral mu-receptor antagonists decrease the gastrointestinal complications of perioperative systemic opioid administration without antagonizing the analgesic benefits of these drugs.OBJECTIVE:
To investigate the impact of alvimopan in opioid-naive patients undergoing major spine surgery.METHODS:
Patients undergoing >3 levels of thoracic and/or lumbar spine surgery were enrolled in this prospective, randomized, double-blind study to receive either alvimopan or placebo prior to and following surgery. Opioid consumption; pain scores; and time of first oral intake, flatus, and bowel movement were recorded.RESULTS:
A total of 24 patients were assigned to the active group and 25 were assigned to the placebo group. There was no significant difference in demographics between the groups. Postoperatively, the alvimopan group reported earlier time to first solid intake [median (range) alvimopan 15 h (3-25) vs placebo 17 h (3-46), P < .001], passing of flatus [median (range) alvimopan 22 h (7-63) vs placebo 28 h (10-58), P < .001], and first bowel movement [median (range) alvimopan 50 h (22-80) vs placebo 64 h (40-114), P < .001]. The alvimopan group had higher pain scores (maximum, minimum, and median); however, there was no significant difference between the groups with postoperative opioid use.CONCLUSION:
This study shows that the perioperative use of alvimopan significantly reduced the time to return of bowel function with no increase in postoperative opioid use despite a slight increase in pain scores.Palavras-chave
