Obtaining informed consent is an ethical requirement for respecting the autonomy of the patient. However, assumptions concerning the patient’s capacity to understand the explanation and its risks sometimes lead to a situation in which the patient signs consent form without a true understanding of the possible complications and ramifications of the procedure. Sufficient time must be allocated to assure that the patient has a full understanding of the risks and benefits and that the patient’s questions have been answered before he or she signs the consent form.
