✦ Synopsis

The intra-operative hemodilution and blood auto-transfusion is a blood-saving technique that can be performed when major blood loss is expected. The effects of this technique were studied in 30 microsurgical free flap transplantation patients. Between 400-600 ml blood was collected from the patients before surgery. The patients received dextran, a balanced salt solution, and glucose with the ratio of 3:1 to the collected blood volume, bleeding, and urine before the blood auto-transfusion. There were no significant changes in RBC, HCT, MCV, blood pressure, or heart rate. Of the 30 free flaps, 28 were successful with a 93.3% survival rate. The safety of intra-operative hemodilution and autologous blood transfusion in microsurgery as well as the effect of hemodilution on transplanted flap survival are discussed in this study.

A new model is presented that adapts the standard experimental groin free flap model to the mouse. The femoral vessels upon which the microvascular anastomoses are based are very small (0.2-0.4 mm diameter in the artery), making this a technically challenging exercise.

T h e advent of microsurgical free tissue transfer has initiated a renaissance in oromandibular reconstruction. From its conception in the 1970s, the iliac crest composite free flap (ICCFF) has been central to this reformation.' A decade of continuous clinical utilization has demonstrated its effica
