RESUMEN
【Objective】 To explore the causes of hypothermia in patients undergoing transurethral thulium laser prostatectomy. 【Methods】 A total of 170 patients who underwent transurethral thulium laser prostatectomy in our hospital during Sep.2020 and May 2021 were prospectively enrolled in the study. The patients were divided into normal body temperature group (n=143) and hypothermia group (n=27), based on whether perioperative hypothermia happened. The clinical data were analyzed to evaluate the risk factors of hypothermia. 【Results】 Univariate analysis showed that there were statistical differences in anesthesia time, operation time, prostate size and total amount of perfusion fluid between the two groups (P<0.05). Logistic analysis showed that the size of prostate was the independent risk factor of perioperative hypothermia (P<0.05). Patients were further divided according to prostate size. For patients with prostate < 80 g, the size of prostate was the independent risk factor of perioperative hypothermia (P<0.05), while for patients with prostate ≥ 80 g, the amount of perfusion fluid was the independent risk factor (P<0.05). 【Conclusion】 Perioperative hypothermia in patients undergoing transurethral thulium laser prostatectomy is related to the anesthesia time, operation time, prostate size and total amount of perfusion fluid. It is necessary to evaluate the risk factors before operation and take effective thermal insulation measures.
