Efficacy of Oral Gabapentin and Acetaminophen for Postoperative Analgesia in Anorectal Surgery: A Fuzzy Logic Evaluation

Le résumé fourni par la source

Background: The present study attempted to evaluate the effect of oral gabapentin and acetaminophen for postoperative analgesia in anorectal surgery. Methods: This double-blind clinical trial was carried out on 144 patients who were candidates for anorectal surgery. The patients were randomly assigned into three groups of control, acetaminophen 500 mg, and gabapentin 300 mg for two hours before the surgery. Data on pain severity based on the visual analog scale (VAS) were evaluated and analyzed. Results: The results of the current study indicated that in patients taking acetaminophen and gabapentin tablets before surgery, the amount of postoperative pain decreased, and the amount of decrease in postoperative pain in the patients who received acetaminophen and gabapentin tablets compared with the placebo group was significant (P<0.001). Also, an evaluation was done using a proposed fuzzy logic model. Conclusion: Taking acetaminophen and gabapentin tablets one hour before the operation causes a significant reduction in postoperative pain in patients who are candidates for anorectal surgery. The results are promising and encourage one to pay attention to more studies with the goal of possibly using them as a decision-support model in the future.
