[Comparative characterization of changes in visual perception after ketamine and brietal anesthesia in children].

Visual perception is disordered in children aged 10-15 years subjected to surgery under ketamine and brietal anesthesia in an outpatient setting. Psychological testing was carried out during 24 h after intervention. Results of the Rorschach's test indicate that ketamine impairs the quality of visual perception (inadequate evaluation of the size, shape, velocity, etc.). Brietal disorders mainly the integrity of visual image. Visual perception did not normalize 24 h after both anesthesias. Disorders typical of each drug persisted.
