| Sumario: | Objective: The aim of study was to identify risk factors that can be modified to reduce incidence of postoperative shivering in normothermic patient who underwent general anesthesia.
Material and Methods: A retrospective case control study was conducted between January 2017 and August 2018 by assessing the anesthetic records of normothermic patients at a post anesthesia care unit who underwent general anesthesia. A control group of 201 patients was randomly matched with 201 cases by age (±5 years) and site of surgery. Medical records were reviewed for data including patient demographics, operative time, anesthetic medication, type of fluid, core temperature at the end of surgery and occurrence of postoperative shivering. Conditional logistic regression analysis was performed to assess the association between potential risk factors and postoperative shivering.
Results: Higher body mass index (BMI) [odds ratio (OR) 0.91, 95% confidence interval (CI) 0.87-0.96] and higher core temperature at end of surgery (OR 0.33 95% CI 0.18-0.63) are associated with reduced risk of postoperative shivering. Whereas emergency case compared with elective case (OR 3.06 95% CI 1.63-5.72) and longer duration every 10 minutes (OR 1.05 95% CI 1.03-1.08) are associated with an increased risk of postoperative shivering.
Conclusion: Emergency case, longer duration of surgery, lower BMI and lower core temperature at end of surgery were significantly associated with postoperative shivering. |
