Design: This study was conducted as a cross-sectional study. Methods: The study carried out with 114 patients undergoing urological surgery lasting longer than 30 minutes at a state university hospital. The research data were collected using introductory characteristics form and the body temperature monitoring form. Body temperatures of the patients were measured patients’ preoperative period, intraoperative (early-late) period, and postoperative period. Findings: The results showed that the incidences of early-intraoperative and late-intraoperative IPH were 8.8% and 18.5%, respectively, and this incidence was found to be 40.5% in ...
