Average blood loss and the risk of requiring perioperative blood transfusion in 506 orthognathic surgical procedures.
This study quantifies the estimated blood loss in seven groups of orthognathic surgical procedures and the risk of requiring perioperative blood transfusion, and identifies the factors relating to blood loss and need for transfusion. ⋯ The need for blood transfusion in this study was extremely low. Factors contributing to this are believed to be use of hypotensive anesthesia; a single surgical team; and a constant surgical setting. Patients having double-jaw surgery are at greater risk for blood loss than those having single-jaw procedures, and should be so advised, along with the risks of blood transfusion. The authors believe that under the conditions of this study the use of autodonation is not necessary, with the possible exception of complex double-jaw procedures involving small patients.
