Devotees of oriental medicine will not be surprised by the finding, in the British Journal of Anaesthesia, that acupuncture reduces pain after surgery. More unexpected is that chili powder applied to the skin below the knee can produce the same effect!
In this meta-analysis fifteen studies were analysed – over 1100 patients. In each study, acupuncture was compared with control “sham” acupuncture (acupuncture applied to non-acupuncture points).
- Acupuncture patients needed less opioid (morphine-like) pain treatment at 8, 24 and 72 hours after surgery
- Postoperative pain was also significantly less in the acupuncture group at 8 and 72 h compared with the control group.
- The acupuncture treatment group had a lower incidence of opioid-related side-effects such as nausea, dizziness, sedation, pruritus (itching), and urinary retention (inability to urinate).
The authors conclude that “perioperative acupuncture may be a useful adjunct for acute postoperative pain management”. I was intrigued, and decided to explore the methods used in one of the 15 studies in a bit more detail (Kim KS, Nam YM. The analgesic effects of capsicum plaster at the Zusanli point after abdominal hysterectomy. Anesth Analg 2006; 103: 709–13). Read the rest of this entry »
