Incidence of perioperative hypothermia in orthopaedic surgery and risk factors

Abstract

Purpose: The purpose of this research is to determine the incidence with causing factors such as demographic characteristics, type of surgery, type of anesthesia, operation time and operating room temperature of hypothermia during perioperative period of orthopedic surgery. Material and Methods:This research was planned to be defining cross-sectional, which included 116 patients that were operated by orthopedic surgery lasting longer than 60 minutes in a university hospital in western Turkey. During operation and post-op recovery, each patient and lsquo;s body temperature, vitals and room temperature was measured every 20 minutes. Patients with body temperature lower than 36oC were categorized as hypothermia. Results: 31.9% of patients underwent replacement surgery and 35.3% had general anesthesia. 69.8% of the patients were in hypothermia during the 60th minute of the operation.This research has found that during orthopedic surgery, patients' body temperatures dropped 0.66 oC during the first hour of the operation and 1.54oC at the end of operation.When intraoperative 0-60th minutes measurements were compared, body temperature, pulse, systolic and diastolic blood pressure values were found to be statistically significant. It was found that 60th minute measurements were significantly lower than 0th minute measurements. Conclusion:Inadvertent hypothermia is seen frequently in orthopedic patients.It is recommended that frequent body temperature monitoring and warming patients should be routinely practiced during orthopedic surgery.
