Risk factors analysis and prediction model construction of hypothermia during laparoscopic radical gastrectomy for gastric cancer
Objective To analyze the risk factors of hypothermia during laparoscopic radical gastrectomy for gastric cancer and construct a nomogram prediction model.Methods The clinical data of 287 patients who underwent laparoscopic radical gastrectomy for gastric cancer from January 2021 to August 2022 were retrospectively analyzed.According to whether hypothermia occurred during the operation,the patients were divided into hypothermia group and non-hypothermia group.Univariate analysis and multivariate Logistic regression analysis were used to screen out the independent risk factors of hypothermia during laparoscopic radical gastrectomy for gastric cancer.Based on this,a nomogram prediction model was constructed and its effect was verified.Results Among the 287 patients,103 cases had hypothermia,and the incidence of hypothermia was 35.89%.The age of the hypothermia group was greater than that of the non-hypothermia group,the operation time,anesthesia time and operation waiting time were longer than those of the non-hypothermia group,the intraoperative urine volume,blood loss,fluid infusion volume and carbon dioxide(CO2)intake were more than those of the non-hypothermia group,and the proportion of history of hypertension and diabetes complications was higher than that of the non-hypothermia group(P<0.05).The multivariate Logistic regression analysis results showed that age,operation waiting time,history of hypertension and diabetes complications were independent risk factors for hypothermia during laparoscopic radical gastrectomy for gastric cancer(P<0.05).The area under curve(AUC)of the receiver operating characteristic(ROC)of nomogram prediction model based on independent risk factors was 0.818,and the Hosmer-Lemeshow test result was 0.775(P>0.05),indicating that the nomogram prediction model was in good agreement with the actual results.Conclusion The nomogram prediction model of intraoperative hypothermia in laparoscopic radical gastrectomy for gastric cancer is of great significance to identify the key factors of intraoperative hypothermia.
