Autologous blood Transfusion in oral and maxllofacial surgery

Autologous blood tranfusion(ABT) is the safest method for blood transfusion to avoid any risks associated with the homologous blood transfusion(HBT). We reviewed ninety patients retrospectively who had been received ABT at Department of Oral and Maxillofacial Surgery, Yonsei University, SEOUL, KOREA form March 1990 to December 1992. Twenty patients received HBT were used for control group to compare with ABT patients. Age distribution was 14 to 48 years old, the major procedure was orthognathic surgery(96.7%), 7.8% of all ABT-schedulled patients were cancelled to perform ABT bacause of positive HBs-Ag or VDRL in screen tests. An average interval of donation was 5.5 days. And there was no remakable complications associated with blood donation except for 4.4% patients. The hemoglobin level was on the decrease gradually following as sequences of each donation, however it was increased unusually during 3rd. to 4th. Schedule in females. The reticulocyte count was on the increase regularly following as schedules, but it was increased dramatically during 3rd. to 4th. schedule in females. The Hb./Hct. Level of ABT group was decreased more than those of HBT group after sugery. As our results, ideal preparation of blood for severe cases of orthognathic surgery may be 4 pints of ABT plus 1 pint of HBT or 3 pints of ABT plus 2 pints of HBT, however strong efforts must need to avoid HBT during surgery.
