Abstract
Objectives:
The primary objective of this review was to evaluate and compare the efficacy and safety of dexmedetomidine hydrochloride with the efficacy and safety of opioids for postoperative management of children after tonsillectomy and adenoidectomy.
Methods:
We searched the Cochrane Central Register of Controlled Trials (Central) in the Cochrane Library (most recent issue), Medline (1966 to date) through Ovid, Embase (1980 to date), and Web of Science (1945 to date). The number of patients who required rescue analgesics (morphine or fentanyl) in the postanesthesia care unit, the number of patients with emergence agitation, the number of patients with postoperative nausea and vomiting, the time to eye-opening in response to verbal stimuli, and the time to extubation were analyzed.
Results:
We included 5 trials, consisting of 482 patients in total. There were no significant differences in the number of patients who required rescue analgesics in the postanesthesia care unit, the number of patients with emergence agitation, the number of patients with postoperative nausea and vomiting, or the time to extubation between patients who received dexmedetomidine and those who received opioids. Compared with opioids, dexmedetomidine was associated with a significantly decreased time to eye-opening in response to verbal stimuli (mean difference, −2.11 minutes; 95% confidence interval, −3.32 to −0.91 minutes; p = 0.0006).
Conclusions:
Intraoperative use of dexmedetomidine was as effective as opioids in preventing postoperative pain and emergence agitation in children who had undergone tonsillectomy and adenoidectomy.
