Summary of the best evidence for preventing the occurrence of subcutaneous emphysema in laparoscopic surgery.

To retrieve, analyze, and extract evidence related to subcutaneous emphysema in patients undergoing laparoscopic surgery systematically, and provide evidence-based recommendations for reducing its incidence. By browsing the websites of the National Institute for Health and Clinical Excellence, the International Guideline Collaboration Network, the National Guideline Library of the United States, the Registered Nurses Association of Ontario, the Scottish Intercollegiate Guideline Network, the Clinical Practice Guidelines website of the Canadian Medical Association, UpToDate, Web of Science, PubMed, OVID, Cochrane Library, Embase, Chinese Biomedical Database, CNKI, VIP, and Wanfang Database, relevant literatures, guidelines, systematic reviews, evidence summaries, expert consensus, randomized controlled trials, etc. about subcutaneous emphysema in patients undergoing laparoscopic surgery were retrieved. All searches were limited to articles published between 1st January 2010 to 1st August 2023. 2245 articles were identified in total, 10 articles were included after exclude literature that does not meet the standards, including 3 clinical decision-making articles, 2 review papers, and 5 randomized controlled trials. Evidence summarization was conducted from 5 aspects: influencing factors, prevention, establishment and management of pneumoperitoneum, intraoperative monitoring, and intervention methods, 15 pieces of best evidences were summarized. Clinical staffs should transform and apply the evidence-based practices to decrease the incidence of subcutaneous emphysema and enhance the quality of life for patients.
