Zhang Y, Zhang C, Yan M, et al. - In view of the fact that a growing number of studies have demonstrated the effectiveness of acupuncture in the prevention and treatment of postoperative nausea and vomiting, researchers used meta‐analysis to confirm these benefits in children and to determine the optimal time to perform this treatment. Four databases (MEDLINE, EMBASE, CENTRAL, and Chinese Database of Biology and Medicine) have been searched from the beginning until January 16, 2019. Randomized controlled trials were included for assessing the effectiveness of acupuncture in the prevention and treatment of postoperative nausea and vomiting during the early stage (0‐4 hours) and within 24 hours postoperatively in pediatrics. The study included 16 literatures and 1,773 patients undergoing general anesthesia. Findings suggested that acupuncture decreases the risk of postoperative nausea and vomiting, as well as the use of antiemetic remedies, especially during the first four hours following surgery. Acupuncture performed prior to anesthesia has been shown to be the most appropriate intervention time for children.
