Effect Of Intraoperative Heat Preservation On Body Temperature And Homeostasis In Patients Undergoing Radical Resection Of Esophageal Cancer

Objective: To investigate the effect of combined thermal insulation on body temperature and homeostasis in patients undergoing radical esophagectomy for esophageal cancer.Methods: From January 2019 to April 2019,patients with esophageal cancer who met the inclusion and exclusion criteria during elective radical operation in an A-grade hospital in Anhui Province were randomly divided into conventional heat preservation group(control group)and combined heat preservation group(experimental group).The control group received routine preoperative preparation and routine heat preservation measures.On the basis of the control group,the experimental group was pre-insulated with dynamic inflatable insulation blanket and intraoperative insulation.The temperature of patients was monitored and recorded at T0(before induction of anesthesia),T1(60 minutes after induction of anesthesia),T2(120 minutes after induction of anesthesia),T3(after operation),T4(5 minutes before leaving the anesthesia recovery room),and the homeostasis(PH value,glucose,base exce,lactic acidi)was monitored and recorded at T0 and T3.Results:(1)There were no significant differences in gender,age,body mass index,operation time and intraoperative fluid intake between the two groups(P> 0.05),indicating that the two groups were comparable.(2)There was no significant difference in body temperature before anesthesia induction(T0)between the two groups(P > 0.05).The body temperature of the control group at T1 ~ T4 was significantly lower than that of the experimental group at the same time point(P <0.05).The temperature change curve of the experimental group was relatively stable,while that of the control group decreased rapidly,especially in the period of T1~T3.At T3,the average temperature of the control group was lower than 36?,while that of the experimental group was above 36? at all time points.The incidence of hypothermia in the experimental group was significantly lower than that in the control group(2=22.259,P=0.000).(3)At T0,there was no significant difference in the value of PH between the control group and the test group(P > 0.05);at T3,there was significant difference in the value of pH between the control group and the test group(P < 0.05).At T0,there was no significant difference in the value of Glu between the control group and the test group(P > 0.05);at T3,there was significant difference between in the value of Glu the control group and the test group(P < 0.05).At T0,there was no significant difference in the value of BE between the control group and the test group(P > 0.05);at T3,there was significant difference in the value of BE between the control group and the test group(P < 0.05).At T0,there was no significant difference in the value of Lac between the control group and the test group(P > 0.05);at T3,there was significant difference in the value of Lac between the control group and the test group(P < 0.05).Conclusion:(1)Combined thermal preservation can provide good body temperature protection and effectively reduce the incidence of hypothermia in patients undergoing radical resection of esophageal cancer.(2)The application of combined heat preservation measures in radical resection of esophageal cancer can improve the internal environment disorder of patients and facilitate their rehabilitation,which isworthy of clinical application.
