Despite minimal exposure and extensive draping perioperative hypothermia still remains a problem. Methods In this observational study we compared the effects of two methods of thermal management on the perioperative course of core temperature. The methods were standard thermal management STM with a circulating hot water blanket under the patient forced-air warming with a lower body blanket and warmed infused fluids and an intensified thermal management ITM with additional prewarming using forced-air in the preoperative holding area on the awake patient. Results Nineteen patients received STM and 20 were treated with ITM. On ICU admission ITM-patients had a higher core temperature 36.4 0.7 C vs. 35.5 0.9 C p 0.001 required less time to achieve normothermia median IQR in min 0 0-15 vs. 150 0-300 p 0.003 and a shorter period of ventilatory support median IQR in min 0 0-0 vs. 246 0-451 p 0.001 . Conclusion ITM during TAVI-TA reduces the incidence of hypothermia and allows for faster recovery with less need of ventilatory support.
