Strengths and limitations
postoperative vomiting, postoperative nausea., PONV, Vomiting
This trial, based on previous studies, simplifies the procedure and duration of acupuncture and provides a comparable preventive effect on postoperative vomiting, which contributes to the popularization of acupuncture in preventing PONV. The results also provide strong evidence using anisodamine for PONV prevention.This trial has several limitations. First, this study was conducted in a population with a high risk of PONV and achieved a 30% reduction. It was considered unlikely that this intervention could achieve a comparable effect among female patients undergoing other surgical groups. Vomiting in postoperative 24 h still occurred in 42% of patients who received ST36 acupoint injection with anisodamine. Thirdly, compared to standard prophylaxis, ST36 acupoint injection with anisodamine did not reduce the incidence of postoperative nausea. In addition, the leak rate in this study was higher than the previous reported. Further exploration of effective preventions for this population is still needed.
