Objective To explore the effects of re-heating superficial large vessels on the intraoperative core temperature of patients with lower extremity fractures.Methods From October 2021 to April 2023,a total of 80 lower extremity fracture patients enrolled at Fuyang Traditional Chinese Medicine Hospital were randomly divided into experimental group(40 cases)and control group(40 cases).The full-body thermal blanket during operation,and superficial large vessel re-heating were applied to patients of experimental group and control group,respectively.The intraoperative core temperature and blood lactic acid at different time points were recorded.The intraoperative blood loss,and the incidence of hypothermia and chills were compared between the two groups.Results At 30min,1h and at the end of operation,the core temperature in the experimental group was significantly higher than that of the control group(P<0.05).At 1h and the end of operation,the lactic acid in the experimental was significantly lower than that of the control group(P<0.05).However,there were no significant differences in the intraoperative core temperature and lactic acid at other time points between the two groups(P>0.05).There were no significant differences in the operation time,intraoperative blood loss between the two groups(P>0.05).The incidence of hypothermia and chills in the experimental group was significantly lower than that of the control group(P<0.05).Conclusion Re-heating superficial large vessels can effectively maintain the stability of intraoperative core body temperature of patients with lower limb fractures,and reduce the risk of hypothermia,which is a safe and effective intraoperative thermal insulation method.
