Development and evaluation of a novel predictive nomogram for assessing the risk of intraoperative hypothermia in patients undergoing thoracoscopic pulmonary tumor surgery

Development and validation of an intraoperative hypothermia nomograph model for patients undergoing video-assisted thoracoscopic lobectomy: a retrospective study

“…In this study, the incidence of intraoperative hypothermia in patients undergoing VATS lobectomy was 65.28%, which was at a high level 11 – 13 . The reasons could be as follows: First, patients undergoing VATS lobectomy are routinely placed in a lateral position, exposing more body parts to the environment and losing more heat than supine position surgery.…”

“…One study showed that patients with higher body fat percentage were less likely to develop intraoperative hypothermia, which is consistent with the results of this study (BMI > 23.9 kg/m 2 ) 30 . Body fat acts as insulation, helping the body retain heat 13 . In overweight patients (BMI > 23.9 kg/m 2 ), when the body temperature is reduced, patients with more body fat are more likely to stimulate vasoconstriction to reduce heat conduction to peripheral tissues, so as to maintain the body heat balance 31 .…”

“…It has been reported that the overall incidence of intraoperative hypothermia in some parts of China is 44.3% 11 . The incidence of intraoperative hypothermia was 78.3% in patients undergoing thoracic surgery 12 and 50–72.7% in patients undergoing VATS lung tumor resection 13 . Intraoperative hypothermia is associated with a number of adverse outcomes, including postoperative cardiovascular events 14 , perioperative bleeding, drug metabolism disorders, wound infection, increased risk of postoperative delirium 15 , 16 , and increased risk of deep vein thrombosis 17 .…”
