[Premedication and risks in computed tomography of newborn and infant children].
In very young pediatric patients CT-investigations require sedative-hypnotic drug treatment to ensure complete immobilisation during scanning. The case report of a neonate with respiratory arrest after a repeated CT-premedication underlines the high risk of these procedures, especially in patients with central nervous system disorders. We compared organisational requirements, risks and complication rates of 146 oral and intramuscular promazine medications for CT-scanning of the head in 146 infants and neonates (93.8% adequate sedation response) to those of reported alternative methods. Oral promazine proved to be a very effective and safe medication (average dosage in 57 patients without complications: 5.2 mg/kg body weight/90 minutes before CT-scanning; 96% successful sedation procedures) in comparison to 89 patients with i.m. promazine (average dosage: 2.3 mg/kg body weight/45 min before CT with 92% adequate sedations but a complication rate of 7.9%). For neuropediatric examinations of outpatients fast recovery and EEG-compatibility are further important advantages of oral promazine CT-medication.
