Abstract

Background: There are many drugs to control the pain after surgeries. Aminophylline, metoclopramide, and acetaminophen are known to be able to control pain. In this study, we aimed to compare the effects of these three drugs in controlling pain after strabismus correction surgery.Methods: This was a double-blinded randomized clinical trial on 120 patients underwent strabismus correction surgery in Feiz hospital, Isfahan, Iran. Patients were randomized into 4 groups of aminophylline, metoclopramide, acetaminophen, and placebo. All patients and surgeons were unaware of groups and drugs. After strabismus surgery, patients were assessed using visual analogue scale (VAS) to evaluate their pain. Hemodynamic parameters, as well as extubation and recovery times after surgeries were also evaluated.Findings: Postoperative pain assessments indicated a lower pain intensity in acetaminophen, metoclopramide, and aminophylline, respectively, compared to placebo at the time of recovery entrance and 15 and 30 minutes afterwards (P < 0.001).Conclusion: According to the results of present study, acetaminophen has a better effect in controlling postoperative pain than metoclopramide and aminophylline.
