Ketamine and intraocular pressure in children.

abstract：:The potency of conventional inhaled anesthetics increases with increasing age: the 50% effective dose (minimum alveolar anesthetic concentration [MAC]) for anesthesia in the neonatal animal or human exceeds MAC in the young adult by approximately 30% to 60%. We tested whether this relationship also applies to the alka...
