Clinical Trial Summary

Objective: To observe the clinical effect of lower limb warming blanket combined with dexmedetomidine (DEX) in preventing postoperative delirium (POD) and chills in elderly patients undergoing spinal surgery. Methods: A total of 160 elderly patients undergoing posterior spinal surgery under general anesthesia were selected and divided into control group (group N), heating group (group T), DEX group (group D) and heating combined with DEX group (group TD) according to the random number table method, 40 cases in each group. T group and TD group routine insulation and lower limb heating blanket. DEX was injected in group D and group TD. The dosage of anesthetics, the changes of body temperature and heart rate at different time points during operation, and the occurrence of postoperative chills and POD were compared among the groups.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Intraoperative vital signs monitoring	nasopharyngeal temperature	1 hour
Primary	Intraoperative vital signs monitoring	nasopharyngeal temperature	2 hour
Primary	Intraoperative vital signs monitoring	nasopharyngeal temperature	3 hour
Primary	The incidence of postoperative chills	chills refer to the Wrench classification criteria as follows : 0: no chills; grade 1: peripheral vascular contraction, vertical hair, but no muscle fibrillation; level 2: only one muscle group had muscle fibrillation; grade 3: muscle fibrillation in multiple groups; level 4: general tremor; = 1 level was judged to have chills.	1 hour
Primary	The incidence of POD after operation	The results of POD in each group were recorded, and the POD was evaluated by CAM-CR scale. The incidence of POD at 24,48 and 72 h after operation was compared among the groups	1 day
Primary	Postoperative extubation time	The recovery time from the end of surgery to extubation was recorded.	1 hour
Primary	Postoperative incision infection rate	The incidence of postoperative incision infection was recorded.	1 hour
