Background: Lengthy microvascular procedures carry hypothermia risk, yet limited published data evaluate the overall impact of core temperature on patient and flap morbidity. Although hypothermia may contribute to complications, warming measures are challenged by conflicting reports of intraoperative hypothermia improving anastomotic patency.
Methods: A retrospective review included all free flaps performed by plastic surgeons at an academic medical center from December 2005 to December 2010.
