Conversion phenomenon following general anesthesia.

Two cases have been presented that demonstrate a previously undescribed complication of general anesthesia, i.e., altered recovery of consciousness secondary to hysterical conversion reactions. This potential complication must be considered when an organic cause for the symptoms cannot be found in a psychologically unstable individual. A helpful diagnostic sign is described. Consultation with a psychiatrist is mandatory if immediate alleviation of the symptoms is not obtained by the anesthesiologist and/or the surgeon.
