Effects Of Perioperative Combined Thermal Insulation On Patients Undergoing Laparoscopic Colorectal Cancer Surgery

Effects of perioperative combined thermal insulation on patients undergoinglaparoscopic colorectal cancer surgeryObjective:To explore the influence of perioperative combined thermal insulation technology on patients undergoing laparoscopic colorectal cancer surgery.In order to reduce the occurrence of perioperative hypothermia and related complications during and after operation,and provide reference for clinical practice.Methods:1.Grouping:A total of 60 patients with colorectal cancer undergoing laparoscopic surgery under general anesthesia in our hospital from March 2021 to December 2021 were selected by purpose sampling method,and divided into experimental group and control group,with 30 patients in each group.2.Intervention methods:Experimental group:Patients were covered with cotton before surgery（the cotton quilt was kept in an incubator at 37℃）.During the operation,the temperature of the medical physical thermometer was heated to 37℃,the infusion liquid was heated to 37℃through the transfusion transfusion heater,and the temperature of the pneumoperitoneum gas CO₂ was set at 37℃.After surgery,patients were transported to the ward using disposable inflatable blankets at 37℃.Control group:Routine thermal insulation was given,during the operation,the temperature was heated to 37℃by using a medical physical thermometer,the infusion liquid was heated to37℃by using a blood transfusion transfusion heater,and the temperature of pneumoperitoneum gas CO₂was set at 37℃.3.Observation indicators:general data collection,intraoperative core body temperature,postoperative chills,postoperative pain,blood gas analysis results.4.Statistical methods:IBM SPSS Statistics 24.0 statistical software was used for analysis.Quantitative data can be collected according to normal distribution or approximate normal distribution by the t-test,and can be expressed as?±?.Non-normally distributed data were represented by M(P₂₅,P₇₅)using rank sum test.χ~2 test or Fisher’s exact test were used for qualitative data with n（%）.Univariate ANOVA and repeated measure ANOVA were used to treat core body temperature and postoperative pain at different time points.P<0.05 was considered statistically significant.Results:1.A statistically significant difference was not observed between gender,age,BMI,preoperative temperature,surgical site,duration spent under anesthesia,time spent operating,anesthesia time,operation time,temperature and humidity in the OR,and amount of intraoperative infusion volume between 2 groups（P>0.05）.2.In the experimental group,2 patients developed perioperative hypothermia（6.67%）,and there were 10 cases in the control group,and the incidence was 33.33%,the difference was statistically significant（P=0.010）.At the first hour after the operation,the body temperature of the experimental group was 36.31±0.14℃,and that of the control group was 36.20±0.09℃,the difference was statistically significant（P=0.001）.At the second hour after operation,the body temperature of the experimental group was 36.22±0.15℃,and that of the control group was36.09±0.12℃,the difference between the two groups was statistically significant（P=0.001）.At the third hour after operation,the body temperature of the experimental group was 36.13±0.15℃,and that of the control group was 36.05±0.70℃,the difference was statistically significant（P=0.010）.At the end of the operation,the body temperature of the experimental group was36.13±0.11℃,and that of the control group was 36.01±0.15℃,the difference between the two groups was statistically significant（P<0.001）.3.In the experimental group,postoperative chills occurred in 2 patients,with an incidence of6.67%;In the control group,9 patients developed postoperative chills,with an incidence of 30.00%,and the difference between the two groups was statistically significant（P=0.020）.There was no statistical significance in mild,moderate and severe postoperative chills between 2 groups（P>0.05）.4.There were statistically significant differences in pain scores between the two groups at 1,6,12 and 24 hours after surgery（P<0.001）.5.There were no statistically significant differences in PH,Pa O₂and Pa CO₂ values between the two groups at the beginning of the surgery（P>0.05）,and no statistically significant differences in PH,Pa O₂and Pa CO₂values at the end of surgery（P>0.05）.Conclusion:1.Application in the clinical nursing practice perioperative compound heat preservation technology,can effectively reduce the laparoscopic colorectal cancer surgery patients the incidence of perioperative hypothermia,ensure that the core of intraoperative patients can remain relatively constant body temperature,and reduce the patients with perioperative hypothermia caused the incidence of postoperative chills,reduced the degree of postoperative pain,and maintain the body electrolyte,acid-base balance system stability.2.It is beneficial to the safety of patients and a strong guarantee for the smooth operation and rapid postoperative recovery,which is worthy of clinical reference and promotion.
