Objective: Laparoscopic procedures are accompany with a high occurrence of nausea and vomiting after surgery. This study aimed to evaluate the effectiveness of prophylactic intraoperative infusion of dextrose 5% in the avoidence of postoperative nausea and vomiting (PONV).
Materials and Methods: In this randomized, double-blind and placebo-controlled clinical trial, 70 ASA class I women, aged 20-40 years scheduled for diagnostic laparoscopy for infertility were studied. Following induction of anesthesia, study group (n=35) received ringer's solution10 ml/kg/h with glucose 500mg/kg (dextrose 5%) and placebo group (n=35) received ringer solution with 0.9% normal saline in the same volume intraoperatively. The incidence and severity of PONV according to a 4-point scale (0-3) in the post anesthesia care unit (PACU) and during the first 24 hours postoperatively, the first request to antiemetic, and overall antiemetic consumption were compared between two groups.
Results: The overall incidence of PONV was certainly lower in the study group compared with the placebo group (22.85% vs 45.71%; p= 0.03). Severity of PONV was significantly less in the study group (1.14±0.32) than the placebo group (2.50±0.27) (p=0.03). There were analytical compelling difference among the two groups in regard to the first time request to antiemetic after surgery (7.1±1.13 vs 5.71±1.76 hours, p=0.04) and total dose of antiemetic (metoclopramide) 60 vs 100 mg; p=0.001).There is no significant difference in perioperative blood sugar levels changes between two groups (p=0.46).
Conclusion: Intraoperative infusion of dextrose 5% was found to be an efficacious method for the prevention/reduction of PONV without significantly difference in postoperative blood sugar levels in patients undergoing diagnostic gynecologic laparoscopy.
