Transfusion in the exsanguinating Jehovah's Witness patient--the attitude of intensive-care doctors.

The attitude of a Jehovah's Witness patient refusing a blood transfusion during an exsanguinating episode can raise important ethical problems. Various ethical principles, including the patient's autonomy, the sanctity of life and the dignity of the medical profession can be confronted. A total of 242 doctors, members of the European Society of Intensive Care Medicine, answered a questionnaire indicating that 63% would transfuse in those circumstances. However, 26% would never inform the patient about this. Only 45% considered the blood transfusion as appropriate, of whom 25% were unable to define the best option. Doctors from France and Italy more commonly transfuse while those from The Netherlands, the United Kingdom and Scandinavia more commonly withhold transfusion. These data stress the need for a definition of the appropriate medical attitudes towards the patient refusing blood transfusion.
