A Novel Device for Intraoperative Hypothermia Prevention in Patients with Lower Abdominal Surgery: A Prospective...

This study aims to explore the value of lithotomy position thermal sleeve application during lower abdominal surgery in patients with hypothermia. A total of 100 patients who underwent urinary, gastrointestinal, or gynecological operations were included in this study. The patients were randomly divided into two groups: the test group (n = 50) and the control group (n = 50). In the control group, the environment, fluid, patient upper abdomen, and pasted 3 L stone-cut pants were heated. In the test group, the lithotomy position surgical warmer was used based on environment, fluid, and upper abdomen warming. The various indicators present in the two groups were compared and analyzed using the Statistical Package for Social Sciences 19.0. Before the operation, the body temperature was 36.73°C ± 0.28°C in the test group and 36.74°C ± 0.29°C in the control group; the difference between the two groups was not statistically significant (p > 0.05). In the test group, the entry temperature was 36.83°C ± 0.04°C; after 2 hours of operation, it became 37.21°C ± 0.03°C. There were no significant changes in body temperature after 4 hours of operation, basic body temperature was maintained (36.80°C ± 0.02°C). In the control group, the entry temperature was 36.54°C ± 0.05°C; however, it became 35.94°C ± 0.07°C after 2 hours of operation, making the patient prone to developing hypothermia. The differences between the two groups were statistically significant (p < 0.05). In patients undergoing urinary, anorectal, or gynecological operations, the use of a warming intervention during surgery in the lithotomy position can effectively stabilize body temperature and reduce the occurrence of postoperative shivering.
