Objective To evaluate the effect of comprehensive warming measures on reducing the inci-dence of inadvertent perioperative hypothermia(IPH)in patients with extensive burns.Methods A total of 82 patients with extensive burns who underwent escharectomy between January 2020 and January 2024 were selected as the study subjects.They were randomly divided into a control group and an observation group,with 41 patients in each group.The control group received conventional warming measures,while the observation group received comprehensive warming measures in addition to the conventional measures.Body temperature was monitored at the following time points:preoperatively,at the start of anesthesia,at the start of surgery,60 minutes after surgery,120 minutes after surgery,and at the end of surgery.The time to anesthesia recovery,intraoperative fluid infusion volume,blood transfusion volume,urine output,incidence of postoperative shive-ring,and length of hospital stay were recorded.Hemoglobin(HB),platelet count(PLT),prothrombin time(PT),activated partial thromboplastin time(APTT),and blood lactate levels were measured before and after surgery.Results Statistically significant differences were observed between the two groups in intraoperative blood transfusion volume,postoperative blood lactate levels,incidence of IPH,incidence of postoperative shive-ring,and length of hospital stay(P＜0.05).No statistically significant differences were found in intraopera-tive fluid infusion volume,urine output,time to anesthesia recovery,or postoperative levels of HB,PLT,PT,and APTT(P＞0.05).The body temperature of patients in both groups showed a decreasing trend as surgery progressed.The body temperature in the control group was significantly lower than that in the observation group at 60 minutes after surgery,120 minutes after surgery,and at the end of surgery(P＜0.05).Conclusion Comprehensive perioperative warming measures can reduce the incidence of intraoperative hypothermia and decrease intraop-erative bleeding in patients with extensive burns.
