[Refusal of allogeneic blood transfusion by Jehovah's Witnesses. Perioperative management from a legal viewpoint].

The perioperative management of patients belonging to the faith of Jehovah's Witnesses poses two equally difficult problems for physicians due their strict refusal of allogeneic blood transfusions: From a medical point of view everything must be done to avoid fatal anemia and coagulopathy. On the other hand, the physician is confronted with the legal problem even in extreme cases, whether the wishes of the patient, i.e. the religiously motivated right to self-determination, should or even must be followed when despite all preventative measures as described in this case, the risk of fatality is only avoidable by a blood transfusion and therefore represents the only life-saving option. In order to be able to answer this question this article supplies information on the unanimously recognized conditions in the jurisdiction and prevailing legal opinion and derives the consequences for the physician that this does not necessarily signify an unconditional legal obligation in association with a patient directive.
