Optimal Dosing of Preoperative Gabapentin for Prevention of Postoperative Nausea and Vomiting

Pain, Postoperative Clinical Trial

Official title:
Optimal Dosing of Preoperative Gabapentin for Prevention of Postoperative Nausea and Vomiting After Abdominal Laparoscopic Surgery: a Randomized Prospective Comparative Study

Clinical Trial Summary

Overall incidence of postoperative nausea and vomiting (PONV) after general anesthesia is 40-90 % . gabapentin has been incorporated into "fast-track" packages and improved recovery during surgery protocols to avoid unintended side effects associated with opioid alternatives. Interestingly, gabapentin has also been noted to reduce the effects of chemotherapy-induced nausea, effective in treatment of gravidarum hyperemesis, and postdural puncture emesis. Different dosing regimens were tested.The goal of the study is to determine the most effective dose of oral gabapentin given 1 hour prior to surgery on the occurrence and severity of PONV and drug side effects in the first 24 hours postoperatively to find the most effective dose of gabapentin with the least side effects.

Clinical Trial Description

A total of (150) adult patients who will undergo elective abdominal laparoscopic surgery will be included in the study. Written informed consent will be obtained from all patients before randomization. Randomization will be done with the help of a computer generated list of numbers. Patients will be divided randomly and equally into three groups (50 patients each(. The first group of patients will receive 300 mg gabapentin orally 1 hour before induction of anesthesia by a sip of water (group G1), the second group of patients will receive 600 mg gabapentin orally 1 hour before induction of anesthesia by a sip of water (group G2), the third group of patients will receive 900 mg gabapentin orally 1 hour before induction of anesthesia by a sip of water (group G3). Drug formulation will be done by one of the researchers making the dosage of the three groups the same in number and shape of the capsules and then given to a junior anesthetist who is neither involved nor interested in any way in the sample to be administered to the patients surveyed ;
