Abstract
BackgroundLaparoscopic gastric plication (LGP) is a technique in the restrictive category of bariatric procedures that reduces the gastric volume and increases intragastric pressure. Nausea and vomiting are the most common complications after this procedure. The goal of this research is to compare the combined effect of promethazine/dexamethasone versus Metoclopramide/ dexamethasone on the prevention of nausea and vomiting after LGP.MethodsIn recovery, the patients were divided into two groups, the Metoclopramide group which was given Metoclopramide 10 mg plus dexamethasone 4 mg/8 hours intravenous for 48 hours, and the promethazine group which was given promethazine 50 mg /12 hours, intramuscular for the first 24 hours and then promethazine 25 mg/12 hours for the next 24 hours plus dexamethasone 4 mg/8 hours intravenous for 48 hours. The frequency of nausea and vomiting, number of reflux episodes, frequency of epigastric fullness, and the duration of walking around q12 hours were recorded in the first 48 hours post-operation.ResultsEighty patients were enrolled into the study. Promethazine group were found to significantly reduce the incidence of PONV in the first 24 hours compared with the other group (41% vs. 97.5%), relative risk = 0.042 [95% CI = 0.006, 0.299]. The mean numbers of epigastric fullness and severity of epigastria pain were lower in the promethazine group (P = 0.01) and the total opioid requirement was also reduced in promethazine group (32.1 ± 2.6 VS .68.5 ± 4.6 mg). However, the patients in the promethazine group were more sedated, which caused the duration of walking q12 hours in this group to decrease.ConclusionsIn morbidly obese patients undergoing laparoscopic gastric plication, promethazine/dexametasone was more effective than Metoclopramide/dexametasone in preventing and reducing the incidence of nausea, epigastric fullness, and reflux. That combination was also more effective than Metoclopramide in reducing the severity of epigastric pain.
