Objective:To summarize the best evidence for intermittent pneumatic compression devices in preventing venous thromboembolism for trauma patients.Methods:According to "6S" evidence model, computer evidence retrieval was carried out. Guidelines, clinical decisions, evidence summaries, expert consensuses, and systematic reviews regarding intermittent pneumatic compression in preventing of venous thromboembolism for trauma patients were considered. The retrieval time limit was from the establishment of the database to October 31, 2021. Two researchers independently appraised articles, and extracted data for eligible studies.Results:A total of 21 articles were enrolled, including 13 guidelines, 1 clinical decision, 1 evidence summary, 2 expert consensuses, 4 systematic reviews. Totally 27 items of best evidence were summarized from four aspects: pretherapeutic evaluation, contraindications and applicable conditions, therapeutic strategies, training and education.Conclusions:This study summarized the best evidence of using intermittent pneumatic compression devices to prevent venous thromboembolism for trauma patients, which can provide evidence-based practice bases for nurses to implement scientific and effective standardized management of mechanical thromboprophylaxis. It is necessary to select evidence according to clinical practice and patients ′ wishes, so as to improve the effectiveness of using IPC in preventing thrombosis.
