title: Acute neurotoxicity of meperidine in an infant.
abstract: We report a 6-week-old boy with meperidine neurotoxicity. What distinguished our patient from those previously reported was his minimal exposure to therapeutic doses of meperidine in the setting of normal renal function, and no history of sickle cell anemia, cancer, hepatitis, or cirrhosis. In addition, our patient had no abnormal changes in the electroencephalogram during the event. After only 2 doses of meperidine, he exhibited acute orofacial dyskinesias consisting of tongue thrusting, lip pursing, and facial grimacing combined with prominent flexion of the arms and stiffening of his legs. However, a normal sucking response remained. His symptoms resolved over the next 36 hours and did not respond to naloxone. We believe that this unique presentation of meperidine-induced neurotoxicity may be due to changes in the basal ganglia resulting from perinatal hypoxemia.
