ObjectiveTo analyze the effects of comprehensive thermal insulation management on the perioperative hypothermia, stress response and complications of patients treated with posterior spinal surgery.

MethodsSixty patients treated with posterior spinal surgery under general anesthesia were divided into the conventional group and comprehensive group(30 cases in each group)according to theorder of operation time.In the conventional group, the operating room temperature was maintained at 23 ℃, and the non-operating area was covered with a segmented surgical blanket.In the comprehensive group, the periodic room temperature, skin disinfectant heating, intravenous infusion heating and inflatable heating blanket were adopted.The intraoperative blood loss, intraoperative infusion volume, waking up time, leaving the operating room time, core temperature at the time of entering the operating room, endotracheal intubation, after 1 h of skin resection and end of the operation, postoperative levels of blood glucose(GLU) and C reactive protein(CRP), and occurrence of shivering, hypothermia, pressure injury and wound infection in two groups were recorded.

ResultsThe intraoperative blood loss and infusion volume of patients in comprehensive group were significantly less than those in conventional group(P<0.01), and the time of awakening and leaving the operating room in comprehensive group were significantly shorter than those in conventional group(P<0.01).There was no statistical significance in the core temperature between two groups at entering the operating room and after endotracheal intubation(P>0.05).The core temperature in conventional group at 1 h after skin excision and the end of operation were significantly lower than that in comprehensive group(P<0.01).There was no statistical significance in the levels of GLU and CRP between two groups before operation(P>0.05).The levels of GLU and CRP in two groups significantly increased after operation, but which in the comprehensive group were significantly lower than those in the conventional group(P<0.01).The total incidence rate of postoperative complications in the comprehensive group was 3.33%, which was significantly lower than that in conventional group 30.00%(P<0.01).

ConclusionsThe perioperative comprehensive thermal insulation management for patients treated with posterior spinal surgery can effectively stabilize their intraoperative core body temperature, reduce the intraoperative blood loss and transfusion volume, shorten the time of patients waking up and leaving operating room, relieve the surgical stress response, and reduce the incidence of postoperative complications.
