Objective To summarize the relevant evidence for the prevention of intraoperative hypothermia in infant liver transplantation and formulate audit indicators,so as to provide a reference for clinical evidence-based practice.Methods Relevant evidence on the prevention of intraoperative hypothermia in infant liver transplantation was systematically retrieved from domestic and foreign databases with the retrieval time limit from January 1,2000 to December 31,2024.The evidence was summarized and the audit indicators for the prevention of intraoperative hypothermia in infant liver transplantation were constructed.Results A total of 19 literatures were finally included,with 5 guidelines,2 systematic reviews,6 evidence summaries,1 expert consensus and 5 randomized controlled trials (RCTs).A total of 37 pieces of evidence were formed and categorized into 5 themes:risk assessment,preoperative temperature monitoring and pre-warming,intraoperative temperature monitoring and intervention,postoperative management and quality control,and 16 audit indicators were established.Conclusions The summarized best evidence provides a reference for the prevention of intraoperative hypothermia in children.Nursing staff can conduct baseline audits with the help of audit indicators during application,select evidence based on audit results,reduce the incidence of intraoperative hypothermia in children,and ensure the safety of children during the perioperative period.
