Abstract: Objective To search,evaluate and summarize the evidence on postoperative complication prevention and management of patients with left ventricular assist device（LVAD） implantation,and to provide reference for clinical work. Methods The PIPOST model was used to establish evidence-based problems,and the search strategy was formulated to search Chinese and English databases,guide websites,professional association websites for the guidelines,clinical decisions,expert consensuses,systematic reviews,and original studies according to the "6S" model. The date of the search was from inception of the database to May 1,2023. Two researchers independently conducted literature quality evaluation,evidence extraction,and summarization. Results A total of 18 articles were included,including 1 clinical decision-making,10 expert consensuses,3 guidelines,and 4 cohort studies. Finally,29 items of best evidence were summarized in 6 themes,including circulatory system monitoring and management,device-related monitoring and management,wound management and infection monitoring,digestive system monitoring and management,thrombosis prevention and management,neural system monitoring and management of LVAD patients. Conclusion This study summarized the best evidence in detail for postoperative complication prevention and management of LVAD implanted patients,which is scientific and practical,and can provide evidence-based basis for medical staff to carry out postoperative complication prevention and management of LVAD patients.
