INCOMPETENCY OF CURRENT PRACTICE OF BLOOD ORDERING FOR ELECTIVE SURGERIES IN IMAM KHOMEINI AND SHAHID MOTAHARI HOSPITALS IN URMIA, DURING THE 2nd TRIMESTER OF 2007

Background & Aims: Frequently, blood units ordered and cross-matched for elective surgeries are not used. This study was designed to evaluate the current practice of blood ordering for elective surgeries in Imam and Motahari Hospitals in Urmia. Materials & Methods: In this cross sectional study, 895 patients underwent 29 different kinds of surgery during three months. The overall cross-mach to transfusion ratio, transfusion probability, and transfusion index were calculated. The same indices were calculated for each kind of surgery separately. Results: For 895 patients undergoing elective surgery, 1732 cross-matched blood units were ordered. Furthermore, 222 blood units out of 1732 were utilized for 144 patients in operation rooms. Overall cross-match to transfusion ratio and transfusion index was 7.8, and 0.25, respectively. With the exception of gastrectomy and debridement of thermal induced wounds, in remaining surgeries cross­match to transfusion ratio was significantly higher than acceptable value of 2.5. Highest transfusion indices were related to gastrectomy, esophagectomy and open reduction of leg fractures. Conclusion: The current practice of blood ordering for elective operations leads to significant deviation from standard values. Observance of scientific principles of blood ordering can lead to a decrease in unnecessary blood ordering, working pressure on blood bank, and wastage of blood units. It seems that the current pattern of preoperative blood ordering should be seriously reevaluated
