To analyze the correlation between the changes of body temperature during laparoscopic radical gastrectomy and pressure injury and microenvironment of the compression site.

Ninety-five patients who underwent laparoscopic radical gastrectomy in Rocket Army Specialty Medical Center from September 2019 to September 2022 were analyzed retrospectively.The patients were divided into occurrence group and non-occurrence group respectively according to the occurrence of postoperative stress injury.The changes of body temperature and microenvironment at the beginning of operation and 30 min, 1 h, 1.5 h and 2 h after operation were compared between the two groups.The microenvironment included the temperature and humidity of shoulder, hip and heel.Pearson correlation analysis was used to calculate the relationship between body temperature and microenvironment, and Logistic multivariate regression analysis was used to summarize the influence of low temperature and microenvironment changes on the occurrence of stress injury.

Among the 95 patients, 17 patients had prThe body temperature and humidity of shoulder, hip and heeThe body temperature and humidity of shoulder, hip and heel in the occurrence group increased at 1.5 h and 2 h after the operation, and were higher than those in the non-occurrence group, with statistically significant differences(P<0.05). Pearson correlation analysis showed that the intraoperative body temperature was positively correlated with the temperature and humidity of shoulder, hip and heel(P<0.05). Logistic multivariate regression analysis showed that diabetes mellitus, intraoperative hypotension, intraoperative maximum body temperature≥37.4 ℃, temperature change at the compression site≥0.5 ℃and humidity change at the compression site≥1% were all independent risk factors for stress injury in patients undergoing laparoscopic radical gastrectomy(P<0.05).

Patients undergoing laparoscopic radical gastrectomy for gastric cancer have higher body temperature and more obvious changes in microenvironment at the compression site during operation, and the increase of body temperature and microenvironment at the compression site are related to the increased risk of pressure injury.
