Standardized Perioperative Protocol and Routine Ketorolac Use for Head and Neck Free Flap Reconstruction

Background: No consensus exists on ideal perioperative management or anticoagulation regimen for free flap reconstruction of the head and neck. Perceived benefits from antiplatelet therapy need to be balanced against potential complications. Ketorolac, a platelet aggregation inhibitor and a parenteral analgesic, was introduced as part of a standardized perioperative protocol at our institution. In this study, we aimed to examine the impact of implementation of this protocol as well as complications associated with the routine use of perioperative ketorolac in a diverse group of patients who underwent head and neck free flap reconstruction. Methods: A single institution retrospective review was performed, including all patients who underwent head and neck free flap reconstruction between October 2016 and November 2019. Patients were divided into two cohorts: those who received ketorolac as part of a standardized protocol, and those who did not. Results: Twenty-four consecutive patients with 24 head and neck free flaps were evaluated. Eighteen patients were in the standard protocol, and six were not. There were no microvascular thromboses, flap failures, or hematomas in either group. Intensive care unit length of stay and opiate use were significantly reduced in the standardized protocol group. Conclusions: A standardized perioperative protocol for head and neck free flap reconstruction can reduce hospital and intensive care unit length of stay. No statistically significant differences in complication rates were identified when comparing ketorolac use and perioperative regimens among patients undergoing a diverse set of microsurgical head and neck free flap reconstructions.
