Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with either TURis or transurethral resection of the prostate method

Abstract

Purpose: The purpose of the study was to investigate the incidence of perioperative hypothermia in urology patients undergoing transurethral resection with either TURis or transurethral resection of the prostate method and to recognize the risk factors that were responsible for the occurrence of hypothermia intraoperatively in these patients. Methods: It was a randomized prospective study. A total of 168 patients, according to American Society of Anesthesiologists physical status I–III, were scheduled for transurethral resection either with TURis or transurethral resection of the prostate method. We measured the core body temperature before (preoperative), during (perioperative) and after (postoperative) the surgery. Age, body mass index, American Society of Anesthesiologists score, duration of surgery, preoperative prostatic volume, and vital signs were also recorded. Results: The prevalence of inadvertent hypothermia was 64.1% for the TURis group and 60% for the transurethral resection of the prostate group. Hypothermic patients in TURis group were significantly older (87.7 ± 1.7 vs 68 ± 6.7 years, p < 0.05) and had lower body mass index (26.9 ± 3.6 vs 29.2 ± 2.7, p < 0.05), while hypothermic patients in the transurethral resection of the prostate group were significantly older (86 ± 1.1 vs 70 ± 7.4 years, p < 0.05) and had notably higher duration of surgery (140.6 ± 28.9 vs 120.3 ± 14.3 min, p < 0.05) than normothermic patients. Conclusion: Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with both TURis and transurethral resection of the prostate method is of high incidence. We recommend monitoring of the temperature of core body of all these patients, especially those with advanced age and lower body mass index.

Risk Factors for Intraoperative Hypothermia during Holmium Laser Enucleation of the Prostate

“…We identified the following predictors of hypothermia: age, BMI, operative time, and spinal anesthesia. Age and operative time were also reported as risk factors for TUR-P [18], while BMI, anesthesia method, and hypothermia have not been reported previously.…”

Perioperative Hypothermia Is Associated With Increased 30-Day Mortality in Hip Fracture Patients in the United Kingdom: Α Systematic Review and Meta-analysis

“…Inadvertent perioperative hypothermia, defined as a body temperature ,36.08C, has been reported in 10%-90% of patients undergoing major surgery. [1][2][3] According to National Institute for Health and Care Excellence, inadvertent hypothermia may occur during the preoperative, intraoperative, or postoperative phase. 4 It is associated with increased mortality, life-threatening arrhythmias, 5 altered antibody and cell-mediated immunity, and tissue hypoxia and an increased risk of surgical site infections.…”
