OBJECTIVE: To evaluate the effects of acupuncture anesthesia on the consumption of sedatives and anesthetics， pain， and time consumption in patients undergoing colonoscopy， thus providing evidence that acupuncture anesthesia should be extended to endoscopists and ***: Four English and four Chinese databases were searched for randomised controlled trials of acupuncture anaesthesia in patients undergoing colonoscopy， published from database inception to 1 March 2023. Outcomes were consumption of sedatives and anaesthetics， pain tolerance， visual analog scale(VAS) score， the meantime consumption of examination， satisfaction， and adverse reactions. RESULTS: Thirty-one randomized controlled trials with a total of 4790 participants were included. Results showed that acupuncture anaesthesia significantly reduced consumption of sedatives and anaesthetics[9 studies， n = 944， standardized mean difference (SMD)= -0.82， 95% CI(-1.31， -0.33)， P = 0.001]， VAS score [9 studies， n = 1790， mean difference (MD)= -1.13， 95% CI(-1.70， -0.57)， P＜0.001]， meantime consumption [21 studies， n= 3799， MD = -2.09， 95% CI(-3.15， -1.03)， P＜0.001]and adverse reactions of colonoscopy [7 studies， n = 738， odds ratio (OR) = 0.17， 95% CI (0.10， 0.28)， P＜0.001]. Acupuncture also significantly improved pain tolerance [14 studies， n= 1661， OR = 7.05， 95% CI(3.79， 13.12)， P＜0.001]， while no beneficial effects were found for satisfaction[7 studies， n = 843， SMD = 0.02， 95% CI(-0.38， 0.43)， P = 0.91]. CONCLUSION: Acupuncture has beneficial effects on patients undergoing colonoscopy， particularly in reducing consumption of sedatives and anaesthetics， alleviating pain， shorteningthe time consumption of examination and preventing adverse events. As an alternative， effective， inexpensive， and accessible approach， acupuncture anaesthesia should be extended to endoscopists and anaesthesiologists.
