ARE TRANSFUSIONS OVERRATED - SURGICAL OUTCOME OF JEHOVAH WITNESSES

Physicians as well as their patients are quite familiar with the ever growing list of complications of transfusion. Blood is usually administered by physicians with the nearly unchallenged view that failure to transfuse would have dire consequences. Evidence supporting that view is very difficult to obtain. Although no controlled trial exists, data are collected from 16 reports of the surgical outcome of a series of patients of the Jehovah's Witness faith who were not given transfusion for operations during which transfusion is typically given. Analysis of these data supports the concept that approximately 0.5% to 1.5% of such operations are complicated by anemia resulting in death. This risk of not transfusing patients must be weighed against the cost, morbidity, and mortality that would be expected to accrue had these patients been transfused. These concepts should be employed whenever one is formulating a risk-benefit ratio for patients for whom transfusion is contemplated.
