Background:
Tonsillectomy is one of the most common surgical procedures. This study
compared the effect of Pregabalin and Clonidine on postoperative pain in adult patients undergoing
elective tonsillectomy.
Methods:
This randomized, double-blind, prospective clinical trial was conducted among 92
patients aged 20 to 50. The clonidine group (C) was given 150 µg of clonidine tablet 90 minutes
before surgery, and the pregabalin group (P) was given 300 mg of pregabalin tablet 90 minutes
before surgery. The results were analyzed by SPSS 25, and statistical analysis consisted of chisquare, T-test, and χ2 tests, and a p-value less than 0.05 was considered significant.
Results:
The mean pain score and analgesic consumption scores in the pregabalin group were lower
than in the clonidine group. According to the t-test, there was a significant difference between the
two groups regarding pain score and analgesic consumption (p <0.05). Hemodynamic variation in
both groups had no significant differences (p >0.05).
Conclusion:
The present study showed that pregabalin reduced postoperative pain and analgesic
consumption more effectively than clonidine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
