【 摘 要 】

The incidence of transfusion has increased day by day due to many factors, including increasing population, enhanced expertise and facilities to operate once inoperable conditions and the willingness of the public to pay high cost of advanced surgical procedures. Trauma services have been well-organized now and victims may have massive transfusion. Many authors have pointed out the need of protocols and guidelines to be followed to avoid transfusion associated risks and complications. Under-transfusion has been preferred to over-transfusion and a need to have a ‘Maximum Surgical Blood Order Schedule’ has been stressed.
