[The jurisprudence about blood transfusion and informed consent of Jehovah witnesses].

The law N° 20.584 established the informed consent. This could suggest that patients have a right to refuse a blood transfusion. However, the dominant jurisprudence in protection claims filed against Jehovah Witnesses who rejected a blood transfusion, reveals that they do not have such a right. There were two exceptions in 2008, where courts acknowledged the patient's autonomy and denied the petition to authorize a blood transfusion. Most cases precede law N° 20.584. However, those cases which were upheld by the courts after the promulgation of the law, although few, follow exactly the same doctrine as before the appearance of this act.
