Abstract

The perioperative use of vasopressors in free flap surgeries is controversially debated. The predominant concern is pedicle blood supply will be negatively affected, thus leading to increased post-operative complications. However, little is known about the relationship between vasopressor use and its impact on intrinsic blood supply of free flaps. Comorbidities that diminish blood circulation may cause a higher risk of necrosis from vasopressor use due to the decreased intrinsic free flap blood supply. The aim of this study is to establish the role of peri-operative vasopressors in free flap necrosis based on flap localization and patients’ comorbidities
