ObjectiveTo evaluate the effectiveness of acupuncture as an analgesic during labor.DesignA randomized, unblinded, controlled study.SettingA labor ward in a University Hospital.PatientsParturients at term.InterventionsOne group received acupuncture (N = 106); another did not (N = 92). A second control group (N = 92), drawn from the labor ward protocol, consisted of patients who met the eligibility criteria for the study and were matched to the “no acupuncture” group by parity, but who had not been offered the opportunity to take part. Outcome measure “effectiveness of acupuncture” was measured by the requirement for use of meperidine.ResultsMeperidine was given to 11% of the acupuncture group, 37% of the no acupuncture group (P< 0.0001), and 29% of the control group. The use of other analgesics was also lower in the acupuncture group. Patient satisfaction was high: 89 of 103 patients asked said they would want acupuncture during another labor.ConclusionsAcupuncture during labor reduced the requirement for other painkillers and has high patient satisfaction in this randomized, unblinded, controlled study.
