Evaluation of Warming Effectiveness on Physiological Indices of Patients Undergoing Laparoscopic Cholecystectomy Surgery: A Randomized Controlled Clinical Trial

Abstract

Purpose: The present study aimed to evaluate the impact of warming on physiological indices of patients undergoing laparoscopic cholecystectomy. Design: The study was a three-group randomized controlled clinical trial. Methods: In the present study, 96 patients were assigned to three groups: forced-air warming system group; warmed intravenous fluid group; and control group. The intervention was performed immediately after the anesthesia induction. Physiological indices (core body temperature, blood pressure, and heart rate) were evaluated at 15-minute intervals, and postoperative shivering was also recorded. Findings: The mean systolic blood pressure and the mean heart rate were significantly different in each warming group before, during, and after surgery, but the three groups had no significant differences in terms of physiological indices at any time (P > .05). Postoperative shivering was not seen in any group. Conclusions: Both interventions had similar effects on physiological indices. Therefore, the recommendation is to use the warming method according to patient's other conditions.
