Summary of the best evidence for the prevention of intraoperative unplanned hypothermia in patients undergoing laparoscopic surgery

Background: This study aimed to search, analyze, and summarize relevant evidence for the prevention of unplanned hypothermia in patients undergoing laparoscopic surgery, so as to reduce the incidence of unplanned hypothermia in patients undergoing laparoscopic surgery and provide a reference for clinical medical staff.

Methods: According to the evidence pyramid model, relevant literature were retrieved by computer in databases. Literature quality evaluation and the evidence grading system of the Australian JBI Evidence-Based Health Care Centre Evidence Recommendation Rating System were used to evaluate the literature quality and determine the level of evidence. The time limit for retrieval was from the establishment of the databases to March 31, 2021.

Results: A total of 12 studies were included in this study. Of these, 5 evidence items were finally extracted, and 15 pieces of best evidence were summarized, including the risk assessment of hypothermia in patients undergoing laparoscopic surgery, temperature monitoring, ambient temperature, passive insulation measures, and active insulation measures.

Conclusions: The evidence for the prevention of unplanned hypothermia in patients undergoing laparoscopic surgery provided evidence-based approaches for reducing the incidence of intraoperative hypothermia for clinical staffs. It is suggested that the cultural characteristics of China, medical resources, and patients' own conditions should be considered when applying the evidence.
