BACKGROUND: In free flap head and neck reconstructions, hemodynamic management is complicated by the deleterious effects of excessive crystalloid administration. Patients may undergo periods of hypotension or excess fluid administration. The purpose of this study was to present our examination of the hypotheses that intraoperative hypotension and blood pressure lability are associated with increased fluid administration and flap failure. METHODS: We reviewed the records of 445 patients undergoing head and neck surgery involving free tissue transfer...
