Surgical Site Infection in Thoracic Surgery Is Not Associated With Perioperative Hypothermia

Introduction: The Surgical Care Improvement Project (SCIP) added the SCIP-Inf-10 measure to mandate that all surgical patients have perioperative temperature management to reduce surgical site infection. While the basis of this measure originated in colorectal surgery, we hypothesized that this would also apply to thoracic surgery patients. Methods: This was a retrospective single-center pilot study reviewing two years of thoracic surgery cases for the incidence and duration of hypothermia during the operation and surgical site infection occurring within 30 days. Hypothermia was defined as a core temperature of < 36 degrees C. Results: A total of 317 patients were included in the study. Sixty-two percent of patients were identified as hypothermic. The average intraoperative temperature was 35.4 degrees C +/- 0.8 degrees C in the hypothermic group and 36.4 degrees C +/- 0.3 degrees C in the normothermic group. There were four surgical site infections in the study with three cases from the <36 degrees C group (p = 1). There was no difference in average post-anesthesia care unit length of stay between the groups. The average hospital length of stay was 5.5 +/- 5.2 days for the hypothermic group and 8.6 +/- 12.8 days for the normothermic group (p=0.0024). Conclusion: Perioperative hypothermia was common in thoracic surgery and did not have a negative impact on surgical site infection.
