Abstract

Purpose
This study aimed to analyze the risk factors influencing intraoperative hypothermia in patients undergoing breast cancer surgery.
Methods
Data were collected from 129 patients who underwent breast cancer surgery at a general hospital in City B from May 7 to November 14, 2024. The collected data were analyzed using SPSS/WIN 27 with an independent t-test, a χ ² test ( χ ² -test), and logistic regression analysis.
Results
A total of 61 (47.3%) out of 129 patients experienced intraoperative hypothermia. According to the results of the logistic regression analysis, lower BMI (odds ratio [OR]=0.85, CI=0.74~0.98, p=.028), a total amount of IV fluid of ≥500 mL (odds ratio [OR]=4.47,CI=1.07~18.75, p=.041), a surgery duration of ≥120 minutes (odds ratio [OR]=4.10, CI=1.02~16.51, p=.047), and intraoperative hypotension (odds ratio [OR]=3.64, CI=1.22~10.86, p=.020) were associated with an increased risk of intraoperative hypothermia.
Conclusion
To prevent intraoperative hypothermia, continuous observation and nursing intervention are required for patients with low BMI or those expected to undergo prolonged surgery. The use of warm fluids during surgery and proper intraoperative blood pressure management is also recommended.
