The purpose of this study is mainly about the feasibility and rationality of moderate sedation combined with acupuncture anesthesia in the application of gastroscopy and colonoscopy ,Then we evaluate the effectiveness and advantages of the combination of acupuncture anesthesia and drug anesthesia.


With the increase of the proportion of the patients who crave for performing painless gastroscopy and colonoscopy in recent years, it is crucial to seek a more secure and effective method of anesthesia or sedation. At present, the universal anesthetic method on gastroscopy and colonoscopy in China is the general anesthesia without intubation which usually uses propofol and opioid analgesics,Although the satisfaction of patients is high, the incidence of anesthesia-related complications and drug-related adverse reactions is high .The incidence of adverse events during the gastroscopy and colonoscopy is high, and the medical expense of anesthesia is high. At present, more than 2/3 of the patients undergo painless gastroscopy or colonoscopy are middle-aged and elderly patients, so the overdose which prolongs the recovery time、discharge time of patients and reduces the recovery quality of patients is common. The moderate sedation, which fundmentally does not affect hemodynamics、autonomous respiration and protective reflexes, is incomparable to general anesthesia . And acupuncture anesthesia also acts as a safe anesthetic method can provide safer analgesic effect.Theoretically,the combination of both of them is a relatively perfect and safe painless method.
