Objective:
to develop a clinically useful perioperative blood transfusion prediction model for patients undergoing a major head and neck surgical procedure requiring free-flap reconstruction.
Design:
retrospective observational study.
Setting:
tertiary care university-affiliated teaching hospital (University Health Network, Toronto, Ontario, Canada).
Patients:
all patients with a head and neck malignant neoplasm undergoing major head and neck surgery requiring free-flap reconstruction.
Main Outcome Measure:
perioperative single-unit red blood cell transfusion.
Results:
all the preoperative variables were tested for an association with perioperative blood transfusion using univariable and multivariable analyses. After multivariable regression analysis, the following preoperative variables were found to be significantly associated with perioperative transfusion: sex, body mass index, T stage, preoperative hemoglobin level, and type of free-flap reconstruction used (ie, osseous vs nonosseous). The regression model was used to develop a transfusion risk score. Receiver operating characteristic curve analysis confirmed adequate discrimination of risk using the transfusion risk score.
Conclusions:
we have developed a reliable model for predicting perioperative blood transfusion requirements in patients undergoing major head and neck surgery requiring free-flap reconstruction. This model can be used for accurate preoperative risk stratification.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
