Background Microvascular surgeons always hold strong belief against the use of vasopressors during free flap surgery. Our aim is to study the safety of intra‐operative vasopressors on free jejunal flap reconstruction. Methods A retrospective chart review was performed on patients undergoing free jejunal flap reconstruction, aiming at investigating the intra‐operative use of vasopressors and the potential complications associated. Results Between 1984 and 2012, 110 free jejunal flaps were performed for reconstruction of circumferential pharyngeal defects created after resection of cancers of the hypopharynx. Intra‐operative vasopressor was given in 81 (73.6%) patients. The most common vasopressors used were ephedrine (42.7%), phenylephrine (14.5%) or both (42.8%). They were administered to the patients before the start of flap harvesting ( n = 32, 29.1%), during the flap harvesting ( n = 30, 27.3%), during microvascular anastomosis ( n = 20, 18.2%), or they were given more than once during the whole operation ( n = 28, 25.4%). The incidence of intra‐operative re‐anastomosis due to thrombosis was 4.5% and the post‐operative flap failure rate was 5.4%. There was no significant relationship between the administration of vasopressor during surgery and the need for intra‐operative re‐anastomosis, post‐operative flap failure and the timing of flap failure. Similarly, there was also no relationship between the timing of vasopressor administration and the above variables. The long‐term stricture rate was 2.7%, the risk of which was not increased by the intra‐operative use of vasopressors. Conclusion The intra‐operative use of vasopressors is safe in free jejunal flap reconstruction. © 2013 Wiley Periodicals, Inc. Microsurgery 33:358–361, 2013.
