Perioperative Management for Microvascular Free Tissue Transfer for Head and Neck Reconstruction – Commentary

Abstract

Le et al. provided a comprehensive commentary on perioperative management for head and neck oncologic patients undergoing microvascular reconstructive surgery. This commentary is based on a detailed review and consensus statements from the Society for Head and Neck Anesthesia (SHANA), an international organization dedicated to enhancing perioperative care for these patients. The consensus statement, published in 2021 by Healy et al., addressed preoperative, intraoperative, and postoperative considerations to optimize clinical outcomes. It included 14 statements from 16 SHANA members across 11 institutions, following two rounds of literature reviews. The commentary emphasized the importance of preoperative nutrition optimization, tobacco cessation, and early recognition of alcohol withdrawal symptoms. In the intraoperative phase, key aspects such as airway management in cases of extensive tumor burden (including awake fiberoptic intubation and tracheostomy), fluid management, hemodynamic monitoring, and multimodal analgesia were briefly discussed. Notably, vasopressors can be used to optimize hemodynamic management without compromising flap perfusion. Additionally, careful fluid resuscitation is crucial to avoid fluid overload, which could increase the risk of flap failure. Multimodal pain management strategies were highlighted, including inhalational anesthetics, anti-inflammatories, narcotics, and regional anesthesia. In the postoperative period, effective communication between healthcare provider teams is essential. Airway management was linked to three of the five consensus statements, underscoring the need for clear and concise communication between the anesthesia and surgical teams. This includes coordinating ventilatory support weaning, extubation planning, and preparation for reintubation if necessary. Such measures help reduce intensive care unit (ICU) utilization, minimize airway-related adverse events, and shorten the length of hospitalization. Overall, the commentary hopes to serve as a guide for multidisciplinary head and neck oncology units across all international centers in managing this complex patient population.
