Aim: To audit the blood utilization in elective Orthopaedic surgeries in our hospital
over two years period and to recommend an optimal blood ordering schedule.
Methods: Retrospectively, Data was collected included type of orthopaedic surgery,
pre and post operative hemoglobin levels, number of units cross matched, number of
units returned, number of units transfused, cross match to transfusion ratio (CT),
transfusion probability (%T), transfusion index (TI), estimated blood loss for each
surgery and predicted fall in hemoglobin. The number of red cell units required for
each procedure was calculated using the equation proposed by Nutall et al,No. of
red cell units required for procedure = Predicted Hb fall (Preoperative -
Postoperative Hb) Results: A total of 472 patients with a median age of 31 yrs (9 to
88 yrs) were evaluated. The mean preoperative hemoglobin was 10.51gm/dl. A total
of 1369 units were cross matched and only 538 units were transfused to 247
patients. 225 patients (47.67%) did not require transfusion during their stay in
hospital. Six of the thirteen elective procedures had CT ratio higher than 2.5. Eight of
the thirteen procedures (61.54%) had low transfusion index (TI
