We have studied the effect of P6 acupuncture on postoperative vomiting in 45 children undergoing tonsillectomy. After induction of anaesthesia and before the start of surgery, 50% of the patients received P6 acupuncture (in the middle of the ventral surface of the wrist) for 5 min.

Auxiliary Medication
No premedication was given. Anaesthesia was induced with i.v. thiopentone 5 mg kg-1,atropine 0.02 mg kg-1,and suxamethonium 1.5 mg kg-1. Manual inflation of the lungs (taking care not to inflate the stomach) was followcd by tracheal intubation and spontaneous ventilation with 66% nitrous oxide and 1.5-2.0% isoflurane in oxygen. I.m. codeine 1.5 mg kg-1 was administered to all patients at the end of surgery. Estimated fluid deficit and maintenance requirements were replaced with i.v. Ringer's lactate solution. After operation, i.m. dimenhydrinate 1.0 mg kg-1 was available if the incidence of vomiting exceeded three episodes during any 1-h period. Further i.m. codeine 1.0 mg kg-1 or oral paracetamol 10 mg kg-1 was available on the ward as required for pain.

Effector
There was no difference in the incidence of vomiting between the acupuncture (39%) and non-acupuncture (36%) groups. We conclude that, when administered after induction of anaesthesia, P6 acupuncture is ineffective in re- ducing vomiting after tonsillectomy in children.

There was no difference in the incidence of vomiting between the acupuncture (39%) and non-acupuncture (36%) groups. We conclude that, when administered after induction of anaesthesia, P6 acupuncture is ineffective in reducing vomiting after tonsillectomy in children."
