Acupuncture as an additional analgesic method in the perioperative period

Abstract

Acupuncture is a traditional Chinese therapeutic method that uses a sterile thin needle technique to puncture the skin at specific strategic points on the body. World Health Organisation has acknowledged acupuncture as a complementary treatment method for over 300 diseases. Nowadays, many available studies conducted in China, the United States, and Europe confirm the efficacy of acupuncture, its analgesic effect, while providing direct health benefits without or with minimal side-effects. There are many scientific evidence mechanisms of acupuncture?s analgesic effects. One of the mechanisms is described in the oldest and best-known Gate Control Theory which explains how pain pathways are modulated through normal anti-nociceptive pathways in the spinal cord. The second mechanism of analgesia shows that there are changes in descendent inhibition of pain pathway and secretion of neurotransmitters when the acupuncture needle is placed at the specific acupuncture point. In addition, it has been proved that there is an increased secretion of endogenous opioids during acupuncture procedures, which help reduce the pain sensations. Analgesic effects of acupuncture on cerebral function have been confirmed with use of functional magnetic resonance imaging and positron emission tomography scans. Although there is an increased number of relevant studies that confirm the effects and benefits of acupuncture therapy in the perioperative period, some important factors are still missing: the standardization process of acupuncture technique, the determination of types of surgery where the acupuncture method shows the best therapeutic effect, the determination of the best technique and time interval for the most effective analgesia.
