Abstract:

Objective: The preoperative cross match to transfusion ratio for common elective general surgical procedures were evaluated in our university hospital to assess the efficacy of ordering of blood and also to compare it with the Maximum Surgical Blood Order Schedule (MSBOS). Materials and Methods: Data was collected retrospectively during a 6-month period in Ain Shams University Hospital. Patients were identified through the transfusion services electronic database and our operating theatre database. Data collected included type of surgery, number of units cross-matched and number of units transfused. This data was used to calculate the C:T ratio and transfusion index. Also we compared the ordering of the blood with the MSBOS to assess the compliance to the international guidelines. Results: A total of 85 patients who underwent elective procedures in general surgery department of Ain Shams University, were included in the study. Out of the 186 units of blood cross-matched, only 72 (38.7%) were transfused. 61.3% of the total cross-matched units were not transfused. The overall C:T ratio was therefore 3.5:1, with the average transfusion index was 0.5. Conclusion: We concluded that the cross match transfusion index was relatively high in the surgical department of Ain Shams University Hospital which clarifies high percentage of blood wastage. The implementation of the MSBOS with the Type and Screen policy may aid in reducing the wastage.
