Forced-Air Warming for Preventing Perioperative Hypothermia During Total Knee Arthroplasty
Sponsor: Shanghai 6th People's Hospital
Summary
Perioperative hypothermia is a common complication during total knee arthroplasty (TKA) and may increase the risk of shivering, delayed anesthetic recovery, and postoperative complications. This historical control study aims to evaluate the effectiveness and safety of intraoperative forced-air warming in preventing perioperative hypothermia in patients undergoing primary unilateral TKA. A total of 240 patients were included. Patients in the historical control group received routine passive warming measures, while patients in the intervention group received additional forced-air warming during the perioperative period. Core body temperature, incidence of inadvertent perioperative hypothermia, anesthetic recovery outcomes, postoperative complications, and safety outcomes were evaluated.
