Vasopressor use in partial flap necrosis in free flap transplant patients with vascular comorbidities: A retrospective study.

Intraoperative use of vasopressors in free flap surgeries is controversially debated. The predominant concern is that pedicle blood supply will decrease leading to post-operative complications. This study examined the role of intraoperative vasopressors, specifically norepinephrine, in free flap partial necrosis based on the patients' comorbidities. We retrospectively analyzed 192 patients who received free flap treatment between 2006 and 2021 and were stratified based on vascular comorbidities. We assessed the role of intraoperative vasopressors using multivariate analysis. Patients who were administered vasopressors did not have a significantly higher risk of partial flap necrosis compared to patients who were not administered vasopressors (OR: 1.439, 95% CI: 0.618-3.348,
