The results indicated that acupuncture was effective in reducing postoperative vomiting, both during the first 4\u00a0hours (RR\u00a0=\u00a00.47, 95% CI 0.26, 0.84; low quality) and within 24\u00a0hours postoperatively (RR\u00a0=\u00a00.74, 95% CI 0.60, 0.91; low quality). Stratifying by the timing of acupuncture, acupuncture was effective in reducing the first 4\u00a0hours (RR\u00a0=\u00a00.34, 95% CI 0.18, 0.64; moderate quality), and 0\u201024\u00a0hours postoperative vomiting (RR\u00a0=\u00a00.81, 95% CI 0.70, 0.93; moderate quality) when performed before and during anesthesia, respectively. Further, the RR value was more robust when acupuncture was performed before anesthesia. Acupuncture was also effective in treating 0\u201024\u00a0hours postoperative nausea (RR\u00a0=\u00a00.73, 95% CI 0.60, 0.88; moderate quality) and in reducing the utilization of remedies during the first 4\u00a0hours (RR\u00a0=\u00a00.64, 95% CI 0.45, 0.89; moderate quality).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Acupuncture reduces the incidence of postoperative nausea and vomiting as well as the utilization of antiemetic remedies, particularly during the first 4\u00a0hours following the operation.
