Acupuncture for Nausea and Vomiting

First, reviews covered postoperative, chemotherapy-induced, and pregnancy-related nausea and vomiting. Specifically, 26 trials with over 3,000 patients showed P6 stimulation outperformed sham for postoperative nausea and vomiting in adults and children. Moreover, pooled data indicated P6 stimulation surpassed antiemetic drugs for nausea and matched them for vomiting. Additionally, P6 stimulation proved equally effective across invasive and noninvasive methods. Next, 11 trials with over 1,200 patients examined chemotherapy-induced nausea and vomiting. Electroacupuncture reduced first-day vomiting, but manual acupuncture did not. Meanwhile, acupressure alleviated first-day nausea but not vomiting. However, wristwatch-like devices showed no effect. Finally, six trials with about 1,150 patients studied pregnancy-related nausea and vomiting, yielding mixed results. Some trials favored P6 stimulation, while others showed no clear benefit or preferred method.
