The notion that consent to surgery must be
informed implies not only that information should be provided
by the surgeon but also that the information should be understood
by the patient in order to give a foundation to his or her
decision to accept or refuse treatment and thus, achieve
autonomy for the patient. Nonetheless, this seems to be an
idyllic situation, sincemost patients do not fully understand the
facts offered and thus the process of surgical informed consent,
as well as the patient’s autonomy, may be jeopardized.
Informed consent does not always mean rational consent.
