The.hen.iu.im.i Jung, which was published in the mid-3rd century, became the oldest acupuncture book that is still in existence in the modern era. 29 Other books like the Cu Kuei Chen Chang, written by the Director of Medical Services for China, were also influential during this period, but were not preserved. 29 In the mid 7th century, on using acupuncture on the ear. 29 :164 Acupuncture research organizations were founded in the 1950s and acupuncture services became available in modern hospitals. 27 China, where acupuncture was believed to have originated, was increasingly influenced by Western medicine. 27 Meanwhile, acupuncture grew in popularity in the US. Infection.s caused by a lack of sterilization, but at that time it was believed to be caused by use of the wrong needle, or Reports included 38 cases of infections and 42 cases of organ trauma. 10 The most frequent adverse events included pneumothorax, and bacterial and viral infections . 10 A 2013 review found without restrictions regarding publication date, study type or language 295 cases of infections; mycobacterium was the pathogen in at least 96%. 18 Likely sources of infection include towels, hot packs or boiling tank water, and reusing reprocessed needles. 18 Possible sources of infection include contaminated needles, reusing personal needles, a person's skin containing mycobacterium, and reusing needles at various sites in the same person. 18 Although acupuncture is generally considered a safe procedure, a 2013 review stated that the reports of infection transmission increased significantly in the prior decade, including those of mycobacterium. 18 Although it is recommended that practitioners of acupuncture use disposable needles, the reuse of sterilized needles is still permitted. 18 It is also recommended that thorough control practices for preventing infection be implemented and adapted. 18 The Xingnao Kaiqiao approach appears to be a safe form of treatment. 147 Fainting was the most frequent adverse event. 147 Fainting while being treated, haematoma, and pain while being treated are associated with individual physical differences and with needle manipulation. 147 A 2013 systematic review of the English-language case reports found that serious adverse events associated with acupuncture are rare, but that acupuncture is not without risk. 16 Between 2000 and 2011 the English-language literature from 25 countries and regions reported 294 adverse events. 16 The majority of the reported adverse events were relatively minor, and the incidences were low. 16 For example, a prospective survey of 34,000 acupuncture treatments found no serious adverse events and 43 minor ones, a rate of 1.3 per 1000 interventions. 16 Another survey found there were 7.1% minor adverse events, of which 5 were serious, amid 97,733 acupuncture patients. 16 The most common adverse effect observed was infection e.g. mycobacterium, and the majority of infections were bacterial in nature, caused by skin contact at the needling site. 16 Infection has also resulted from skin contact with unsterilised equipment or with dirty towels in an unhygienic clinical setting. 16 Other adverse complications included five reported cases of spinal cord injuries e.g. migrating broken needles or needling too deeply, four brain injuries, four peripheral nerve injuries, five heart injuries, seven other organ and tissue injuries, bilateral hand enema, epithelioid granuloma, pseudo lymphoma, argyria, pustules, pancytopenia, and scarring due to hot-needle technique. 16 Adverse reactions from acupuncture, which are unusual and uncommon in typical acupuncture practice, included syncope, galactorrhoea, bilateral nystagmus, pyoderma gangrenosum, hepatotoxicity, eruptive lichen planes, and spontaneous needle migration. 16 A 2013 systematic review found 31 cases of vascular injuries caused by acupuncture, three resulting in death. 232 Two died from pericardia tamponade and acupuncture one was from an aortoduodenal fistula. 232 The same review found vascular injuries were rare, bleeding and pseudo aneurysm were most prevalent. 232 A 2011 systematic review without restriction in time or language, aiming to summarize all reported case of cardiac tamponade after acupuncture, found 26 cases resulting in 14 deaths, with little doubt about causality in most fatal instances. 233 The same review concluded cardiac tamponade was a serious, usually fatal, though theoretically avoidable complication following acupuncture, and urged training to minimize risk. 233 A 2012 review found a number of adverse events were reported after acupuncture in the UK's National Health Service NHS but most 95% were not severe, 42 though miscategorization and under-reporting may alter the total figures. 42 From January 2009 to December 2011, 468 safety incidents were recognized within the NHS organizations. 42 The adverse events recorded included retained needles 31%, dizziness 30%, loss of consciousness/unresponsive 19%, falls 4%, bruising or soreness at needle site 2%, pneumothorax 1% and other adverse side effects 12%. 42 Acupuncture practitioners shGould know, and be prepared to be responsible for, any substantial harm from treatments. 42 Some acupuncture proponents argue that the long history of acupuncture suggests it is safe. 42 However, there is an increasing literature on adverse events e.g. spinal-cord injury. 42 Acupuncture seems to be safe in people getting anticoagulants, assuming needles are used at the correct location and depth. 234 Studies are required to verify these findings. 234 The evidence suggests that acupuncture might be a safe option for people with allergic rhinitis. 118 Chinese, South Korean, and Japanese-language A 2010 systematic review of the Chinese-language literature found numerous acupuncture-related adverse events, including pneumothorax, fainting, sub arachnoid haemorrhage, and infection as the most frequent, and cardiovascular injuries, sub arachnoid haemorrhage, pneumothorax, and recurrent cerebral haemorrhage as the most serious, most of which were due to improper technique. 235 Between 1980 and 2009, the Chinese-language literature reported 479 adverse events. 235 Prospective surveys show that mild, transient acupuncture-associated adverse events ranged from 6.71% to 15%. 235 In a study with 190,924 patients, the prevalence of serious adverse events was roughly 0.024%. 235 Another study showed a rate of adverse events requiring specific treatment of 2.2%, 4,963 incidences among 229,230 patients. 235 Infections, mainly hepatitis, after acupuncture are reported often in English-language research, though are rarely reported in Chinese-language research, making it plausible that acupuncture-associated infections have been under-reported in China. 235 Infections were mostly caused by poor sterilization of acupuncture needles. 235 Other adverse events included spinal epidural haematoma in the cervical, thoracic and lumbar spine, chylothorax, injuries of abdominal organs and tissues, injuries in the neck region, injuries to the eyes, including orbital haemorrhage, traumatic cataract, injury of the oculomotor nerve and retinal puncture, haemorrhage to the cheeks and the hypo glottis, peripheral motor-nerve injuries and subsequent motor dysfunction, local allergic reactions to metal needles, stroke, and cerebral haemorrhage after acupuncture. 235 A causal link between acupuncture and the adverse events cardiac arrest, pyknolepsy, shock, fever, cough, thirst, aphonic, leg numbness, and sexual dysfunction remains uncertain. 235 The same review concluded that acupuncture can be considered inherently safe when practice by properly trained practitioners, but the review also stated there is a need to find effective strategies to minimize the health risks. 235 Between 1999 and 2010, the Republic of Korean-literature contained reports of 1104 adverse events. 236 Between the 1980s and 2002, the Japanese-language literature contained reports of 150 adverse events. 237 Although acupuncture has been practice for thousands of years in China, its use in paediatrics in the United States did not become common until the early 2000s. Even.f.hey.ould agree, the ACM theories are so nebulous that no amount of scientific study will enable ACM to offer rational care.” 5 Some modern practitioners support the use of acupuncture to treat pain, but have abandoned the use of qi, meridians, yin, yang and other energies based in mysticism, as explanatory frameworks. 8 25 26 The use of qi as an explanatory framework has been decreasing in China, even as it becomes more prominent during discussions of acupuncture in the US. 257 Academic discussions of acupuncture still make reference to pseudo-scientific concepts such as qi and meridians despite the lack of scientific evidence. 257 Many within the scientific community consider attempts to rationalize acupuncture in science to be quackery, pseudo-science and “theatrical placebo”. 258 Academics Massimo Pigliucci and marten Boudry describe it as a “borderlands science” lying between science and pseudo-science. 259 Many acupuncturists attribute pain relief to the release of endorphins when needles penetrate, but no longer support the idea that acupuncture can affect a disease. 26 257 It is a generally held belief within the acupuncture community that acupuncture points and meridians structures are special conduits for electrical signals but no research has established any consistent anatomical structure or function for either acupuncture points or meridians. n 1 24 Human tests to determine whether electrical continuity was significantly different near meridians than other places in the body have been inconclusive. 24 Some studies suggest acupuncture causes a series of events within the central nervous system, 260 and that it is possible to inhibit acupuncture's analgesic effects with the opioid antagonist naloxone . 261 Mechanical deformation of the skin by acupuncture needles appears to result in the release of adenosine . 2 The anti-nociceptive effect of acupuncture may be mediated by the adenosine A1 receptor . 262 A 2014 Nature Reviews Cancer review article found that since the key mouse studies that suggested acupuncture relieves patients and which treatments should go with which diagnoses. David Ramey, no single “method or theory” was ever predominantly adopted as the standard. 271 At the time, scientific knowledge of medicine was not yet developed, especially because in China dissection of the deceased was forbidden, preventing the development of basic anatomical knowledge. 27 It is not certain when specific acupuncture points were introduced, but the autobiography of lien Chhio from around 400–500 BC references inserting needles at designated areas. 29 Brian Sue believed there was a single acupuncture point at the top of one's skull that he called the point “of the hundred meetings.” 29 :83 operation; these demonstration cases were also frequently receiving morphine surreptitiously through an intravenous drip that observers were told contained only fluids and nutrients. 281 One patient receiving open heart surgery while awake was ultimately found to have received a combination of three powerful sedatives as well as large injections of a local aesthetic into the wound. 57 After the National Institute of Health expressed support for acupuncture for a limited number of conditions, adoption in the US grew further. 27 In 1972 the first legal acupuncture canter in the US was established in Washington DC 282 and in 1973 the American Internal Revenue Service allowed acupuncture to be deducted as a medical expense. 283 In 2006, a BBC documentary Alternative Medicine filmed a patient undergoing open heart surgery allegedly under acupuncture-induced anaesthesia.
