“…Postoperative hypothermia (PH) is a common physiological abnormality after non-cardiac surgery (1)(2)(3)(4). Evidences show PH is associated with increased postoperative morbidity and mortality (5)(6)(7). Patients with PH have higher incidence of infection, more blood products consumption, longer mechanical ventilation time and length of hospital stay (8,9).…”

Background: Postoperative hypothermia (PH) is a common physiological abnormality associated with increased morbidity and mortality after non-cardiac surgery. The incidence, risk factors of PH and its impact on early outcomes after total aortic arch replacement are not clear. Methods: We conducted a retrospective cohort study in patients with acute type A aortic dissection who underwent total arch replacement from January 2013 to December 2016 at our institution. Basic variables, procedural and postoperative early outcomes were collected. Univariate and multivariate statistical analysis were performed for statistical interpretation. The early outcomes were compared between patients with or without PH. Results: A total of 300 patients (age 53.8±11.5 years, female 63, 21.0%) with acute type A aortic dissection underwent total arch replacement. Forty-four patients (14.7%) developed PH. The independent risk factors of PH are age and the intraoperative lowest bladder temperature. There is no significant difference in major postoperative morbidity and mortality between patients with or without PH. Conclusions: The incidence of PH after total arch replacement in acute type A aortic dissection is relatively low. The independent risk factors of PH in this population include age and the intraoperative lowest bladder temperature. With comprehensive rewarming strategy upon arrival at the ICU, the PH is easy to be corrected, and the adverse effect of transient PH on early outcomes after arch surgery is minimal.

“…This warming method has been proven to be effective during elective aortic surgery [13]. However, patients that undergo emergency aortic repair may remain hypothermic when warmed without appropriate thermal insulation [4,14]. The assessment of artifacts caused by insulating and warming systems on CT brought similar results.…”

Purpose We aimed to assess whether insulating covers and warming systems cause artifacts in fluoroscopy, and whether they alter the radiation dose. Methods Eight insulating and warming systems were wrapped around the phantom in order to obtain images in fluoroscopy, and to measure the absorbed and scattered radiation dose. A dosimeter, endovascular catheters, and stents were placed into a phantom. The other dosimeter was placed outside of a C-arm table, at the operator’s and anesthesiologist’s locations. Results Most of the insulating covers did not cause artifacts in the fluoroscopy and led to a significant decrease in both the absorbed and scattered radiation dose. The highest decrease in the absorbed dose was observed with metalized foil (− 2.09%; p = 0.001) and in the scattered dose with Helios cover (− 55%; p < 0.001). Only one heating system (Ready Heat combined with Hypothermia Prevention and Management Kit cover) caused significant artifacts and increased radiation up to 99% ( p < 0.001). Conclusion Thermal insulation may be maintained during X-ray-guided emergency endovascular procedures in trauma victims. Self-heating blankets should be replaced with another warming system.

“…76 However, an alternative definition proposed by the National Institute for Health and Care Excellence (NICE) in the UK considers a core temperature below 36°C as indicative of hypothermia. 120 This divergence in definitions can pose challenges when comparing research results, which is why the NICE definition was not utilized in this thesis.…”

“…This is also described in a review of studies of hypothermia in aortic surgery. 120 Although most of the studies were performed in elective open aortic repairs, accidental hypothermia was associated with increased organ dysfunction, longer ICU/hospital staylength and in-hospital mortality. In a study of patients with rAAA treated with EVAR (35 patients) and open surgery (25 patients), accidental hypothermia, which was more frequent in open surgery, was associated with higher 30-day mortality.…”
