January 2018Background
Blood loss during major head and neck surgery can be significant. In head and neck cancer patients, complex extirpations with reconstruction can lead to acute blood loss anemia, often in addition to an anemia of chronic disease. Therefore, consideration of blood transfusion in the postoperative course is not uncommon. However, questions remain regarding the ideal criteria for transfusion in these patients. The surgeon seeks to maximize tissue oxygenation especially when managing free tissue transfer, while also weighing the possible deleterious effects of a liberal transfusion regimen. Furthermore, resource utilization concerns play a role in transfusion decision making.
There is a paucity of literature regarding blood transfusion criteria in head and neck surgery, with only one study challenging historic transfusion norms in free tissue transfer patients. Other studies have explored the negative associations between blood transfusion and outcomes in head and neck cancer surgery. Where otolaryngology-related data are lacking, high-level evidence from critical care literature can be used to provide more insight.
