The amobarbital interview.

In two apparently disoriented patients, the emergency physician's use of amobarbital quickly eliminated diagnoses of an organic etiology. Although thousands of amobarbital interviews have had no complications, the use of amobarbital should follow a thorough evaluation. The amobarbital interview is a safe and simple technique to discriminate functional from organic illness, thus avoiding unnecessary medical and surgical treatment, neglected illness, and inappropriate disposition.
