An American randomised trial studying acupuncture for postoperative nausea, has shown that children receiving the treatment alongside anti-sickness medication, are less likely to experience symptoms. A total of 161 children aged 3 to 9 and undergoing tonsillectomy, were randomised to receive either acupuncture plus antiemetic drugs, or antiemetics alone. Acupuncture consisted of needling the well-known point Neiguan on each wrist.
During phases 1 and 2 of recovery, the incidence of postoperative nausea and vomiting was 7% in the acupuncture group and 35% in the group on medication alone. This was mainly due to the reduction in nausea. Vomiting was no different between the two groups. The day after surgery, nausea and vomiting was 36% in the acupuncture group and 49% in the medication only group.
