Abstract Background: Enhanced recovery after surgery suggests the use of multimodal analgesia to optimize the perioperative pain management scheme. At present, studies have shown that the application of acupuncture combined anesthesia in thoracoscopy has achieved good curative effect. However, there is no relevant systematic evaluation. Our study is the first meta-analysis of the effectiveness and safety of acupuncture combined anesthesia in pain management after thoracoscopy, in order to provide strong evidence for clinical support. Methods: A comprehensive and systematic literature searching will mainly perform on 7 electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, and WanFang Data, Chinese Biomedical Database) from their inception up to November 30, 2021. We will also search for ongoing or unpublished studies from other websites (eg, PROSPERO, ClinicalTrials.gov, Chinese Clinical Trial Registry) and do manual retrieval for potential gray literature. Only the relevant randomized controlled trials published in English or Chinese were included. Two independent investigators will independently complete literature selection, assessment of risk bias, and data extraction, the disagreements will be discussed with the third party for final decisions. The primary outcome measures: visual analog scale, intraoperative anesthetic dosage, and the consumption of postoperative analgesics. The secondary outcome measures: Pittsburgh Sleep Quality Index, the total sleep time after operation, residence time in the anesthesia recovery room, the duration of hospitalization, and the incidence of adverse reactions and serious events. Assessment of bias risk will follow the Cochrane risk of bias tool. Data processing will be conducted by Stata 15.0 software. Results: We will evaluate the efficacy and safety of acupuncture assisted anesthesia for postoperative pain after thoracoscopy based on randomized controlled trials. Conclusion: This study can provide more comprehensive and strong evidence whether acupuncture assisted anesthesia is efficacy and safe for postoperative pain in thoracoscopy. Registration: The research has been registered and approved on the INPLASY website. The registration number is INPLASY 2021120129.
