Acupuncture is an invasive technique, and therefore not without risk. Hematoma may result from accidental puncture of any circulatory structure. Nerve injury can result from the accidental puncture of any nerve. Brain damage or stroke is possible with very deep needling at the base of skull. Also rare but possible is pneumothorax from deep needling into the lung, and kidney damage from deep needling in the low back. Needling over an occult sternal foramen (an undetectable hole in the breastbone which can occur in up to 10% of people) may result in a potentially fatal haemopericardium. There are clear warnings in responsible texts on acupuncture regarding both the depth to which needles may be inserted, and with regard to the angle at which needles may be inserted. Both these instructions are clearly intended to prevent acupuncture needles from penetrating the lungs, the abdominal cavity, etc.

Needles that are not properly sterilized can transfer diseases such as HIV and hepatitis. In the United Kingdom, British Acupuncture Council (BAcC) members observe the Code of Safe Practice which lays down stringent standards of hygiene and sterilisation for other equipment - members use single-use pre-sterilised disposable needles, which are permanently withdrawn from service after being used in treatment. Similar standards apply in most jurisdictions in the United States. Sometimes, when treating pain or using acupuncture as an anesthetic, a mild electrical current is applied to the needles. This stimulates the nerve cells in the area of the needles so that they become depleted of the chemicals needed to transmit signals (please note this is not an acupuncture effect!). Prolonged stimulation of nerve cells in this way can cause irreversible damage.

Severe injury from acupuncture is extremely rare, but not unheard of. Well-trained, licensed and experienced acupuncturists are less likely to injure a patient. However, in many countries anyone can call himself an acupuncturist, there are no legal requirements with regard to training and education, nor are licensing boards regulated in any way, making it very hard to assess the actual value of licenses and training of acupuncturists. The NIH consensus panel made the following statement about the risks associated with acupuncture: “Adverse side effects of acupuncture are extremely low and often lower than conventional treatments. In a UK study of almost 2000 practitioners covering over 34,000 treatments, there were no serious adverse events and only 43 minor adverse events.

In the USA the National Certification Commission for Acupuncture and Oriental Medicine (www.nccaom.org) tests practitioners to ensure they are knowledgeable about Chinese medicine. Many states require this test for licensing, but each state has its own laws and requirements.

Most acupuncturists in the USA use sterile one-time-use needles. Some still use reusable needles and an autoclave but this practice is declining due to its cost, time and the possibility of failure in sterilizing the needles.
