BackgroundPostoperative nausea and vomiting (PONV) have always been a concern of clinicians and may increase medical costs for patients. Consensus guidelines recommend using multiple antiemetics with different mechanisms as prophylaxis in patients at high risk of PONV. Individualized risk scores for nausea and vomiting and individualized treatment strategies are feasible. This study evaluated the effect of individualized treatment strategies on postoperative nausea and vomiting after laparoscopic gynaecological operations.MethodsThis was a double-blind, randomized, controlled trial. A total of 119 adult patients who underwent gynaecological laparoscopic surgery under general anaesthesia were randomly divided into an individualized treatment group or a control group, with the individualized treatment group receiving individualized prevention according to a preoperative risk score of nausea and vomiting and the control group receiving no individualized prevention. Vomiting, retching, nausea, and use of rescue medication were all recorded for 24 h after the operation. The primary outcome variable was complete response, defined as no emesis or the use of rescue medication 24 h postoperatively.ResultsThe complete response rate was higher in the individualized treatment group (56.7%) than in the control group (23.7%) (95% CI, 0.01-0.27; P < 0.001). The incidences of emesis (18.3% vs. 44.1%, P = 0.002) were significantly lower in the individualized treatment group than in the control group. There were no differences in any nausea (26.7% vs. 33.9%, P = 0.391) or rescue medication use (6.7% vs. 8.5%, P = 0.743). Adverse events and laboratory and electrocardiogram abnormalities occurred no more frequently in the individualized treatment group than in the control group.ConclusionIn conclusion, this single-centre, double-blind, randomized study suggests that an individualized PONV prophylactic treatment strategy based on the number of PONV risk factors could be a safe and effective regimen to reduce the incidence of PONV in adult patients undergoing laparoscopic gynaecological surgery.© 2022.
