American researchers have evaluated the usefulness of acupuncture for postoperative pain. They conducted a systematic review of the evidence, including fifteen randomised controlled trials of acupuncture versus a sham control, and found that at 8 hours and 72 hours after surgery, the acupuncture groups were using significantly less opioid painkillers (eg. codeine and morphine). Furthermore, acupuncture treatment was associated with fewer opioid-related side-effects, such as nausea, sedation, dizziness, itching and urinary retention.
The authors conclude that their review suggests the perioperative administration of acupuncture may be a useful adjunct for postoperative analgesia. Further large, well-designed studies are required to confirm those findings and to answer questions regarding the most efficacious type of acupuncture and optimal timing of administration.
