Battlefield acupuncture (BFA) shows potential benefits for reducing pain intensity and opioid requirement in military veteran patients undergoing surgery.  American clinicians randomly assigned 72 patients undergoing major surgery under general anesthesia to receive either BFA or sham acupuncture as an adjunctive therapy for postoperative pain.  Median 24-hour postoperative opioid consumption (measured in morphine milligram equivalents, MME) was lower in the BFA group compared with the sham acupuncture group (18.3 MME with BFA, versus 38.6 MME with sham).  Subjective pain intensity reported by patients at 6, 12, 18 and 24 hours postoperatively was also lower in the BFA group compared with the sham acupuncture group.  The incidence of postsurgical nausea and vomiting was lower in patients receiving BFA compared to patients receiving sham acupuncture.  No intergroup differences were observed in terms of postoperative anxiety or length or hospital stay.
