BackgroundThoracotomy is a common surgical procedure used in cases such as trauma and cancer resection. It is an invasive procedure in which incisions are made in the chest wall to gain access to the chest. Therefore, it often produces intense postoperative pain. Electroacupuncture has been known for its analgesic effects in various conditions, including cases of postoperative pain. This protocol design is for a systematic review and meta-analysis to gather evidence and investigate the analgesic effects of electroacupuncture in pain after thoracotomy.MethodsThe studies for the systematic review will be searched with keywords on the following 10 databases: PubMed, Cochrane Library (CENTRAL), EMBASE, MEDLINE, Google Scholar, CNKI, KoreaMed, KMBASE, KISS, and OASIS. The search will be done without language restrictions. Only the randomized controlled trials that meet the eligibility criteria will be finally included in the study. The quality of the study will be assessed using the Cochrane Collaborations' risk-of-bias tool, and Cochrane's software RevMan 5.3 will be used for meta-analysis.ResultsThe designed study will provide a systematic review and meta-analysis of the searched and randomized controlled trials that meet the eligibility criteria. Meta-analysis will be performed with pain scores as the main outcome measure, and they may also be performed with additional outcomes. The qualitative and quantitative data synthesis is expected to provide high quality evidence to judge the pain management effect of electroacupuncture for patients who underwent thoracotomy.ConclusionThe conclusion of this systematic review and meta-analysis will provide evidence to judge whether electroacupuncture is an effective analgesic treatment option for patients suffering with post-thoracotomy pain.Prospero Registration NumberCRD42019142157.
