Best evidence summary of mechanical prevention of venous thrombosis in adult patients undergoing abdominal and pelvic surgery

Objective To retrieve,evaluate and summarize the relevant evidence of mechanical prevention of venous thromboembolism(VTE)in adult patients undergoing abdominal and pelvic surgery,so as to provide a scientific basis for clinical practice.Methods We systematically retrieved and screened the guide network and database for evidence on mechanical prevention of VTE in adult patients undergoing abdominal and pelvic surgery,including guidelines,evidence summary,clinical decision-making,systematic review,and expert consensus.The search time limit was to build the database until January 19,2020.Two researchers who had undergone evidence-based training selected appropriate evaluation tools according to different types of literature to evaluate the quality of the literature,and to extract,translate and integrate recommendations.Results A total of 24 articles were included,including 7 guidelines,2 evidence summaries,1 recommended practice,12 systematic reviews,and 2 expert consensus.The evidence was summarized from 6 aspects,namely admission assessment,contraindications,applicable population,starting time,duration and patient education,and a total of 10 recommendations were formed.Conclusions This study summarizes the best evidence for mechanical prevention of VTE in adult patients undergoing abdominal and pelvic surgery,and provides evidence-based evidence for standardizing clinical mechanical prevention.
