title: Anesthesia for EMI scanning in infants and small children.
abstract: Computerized transverse axial scanning is a new, noninvasive method of diagnosing intracranial and orbital lesions. It is mandatory that the patient's head be motionless throughout the scanning procedure. This requirement creates problems in managing infants and small children for the scanning process. Ketamine hydrochloride was given intramuscularly to produce the desired motionless stated in 47 consecutive infants and small children. Satisfactory scans were obtained in all except two cases. Contraindications and precautions to be observed using this technic are discussed. It is believed that intramuscularly administered ketamine is a safe, effective means of providing immobilization for EMI scanning in infants and small children who are normotensive and show no evidence of definitely increased intracranial pressure.
