Jehovah's Witnesses are an enlarging religious community in the US and throughout the world. Members of this faith refuse administration of blood during medical or surgical therapy even if death may occur as a consequence. The surgeon is consequently faced with difficulties and moral dilemmas of caring for these patients. ⋯ The surgical care of Jehovah's Witnesses has become less of an operative risk over the last decade. There are now significant alternatives to the transfusion of blood, such as erythropoietin, iron dextran, aprotinin and Fluosol-DA 20%. Technological surgical developments and advances, such as the cell saver, argon beam coagulator, acute limited normovolemic hemodilution, autologous whole plasma fibrin gel, and controlled hypotensive anesthesia during anesthesia have contributed substantially to a reduction in the operative loss of blood. The time honored rule of hemoglobin of 10 g/dl and a hematocrit of 30% should not require strict adherence in the postoperative care of most patients. The acceptance of a lower transfusion trigger point of hematocrit of 22% and a hemoglobin of 7 g/dl can significantly reduce transfusion requirements without an increase in morbidity. Ethical considerations are discussed and evaluated when treatment restrictions, such as blood transfusion and other life-preserving therapies are limited by religious beliefs or living wills.
