Kleimeyer J, et al. - Researchers sought to identify the incidence and risk factors for postoperative hypothermia across orthopaedic surgical procedures. They reviewed a total of 3,822 procedures. Temperature <36.0°C was defined as hypothermia. In patients who have undergone orthopaedic surgery, intraoperative and postoperative hypothermia are common. They observed hypothermia in 72.5% of patients intraoperatively and 8.3% postoperatively. Intraoperative hypothermia, lower preoperative temperature, female sex, lower body mass index, older age, adult reconstruction by specialty, and hip and pelvis procedures by anatomic region were the risk factors for postoperative hypothermia.
