title: High dose chloral hydrate sedation for children undergoing CT.
abstract: Chloral hydrate is commonly used to sedate children before CT. However, no prospective study has been published of the safety and efficacy of chloral hydrate at high dose levels for children undergoing CT. We define high dose levels of oral chloral hydrate to be 80-100 mg/kg, with a maximum total dose of 2 g. High dose chloral hydrate sedation was administered orally to 295 children for 326 CT examinations. Adverse reactions occurred in 7% of the children, with vomiting being the most common (4.3% of children). Hyperactivity and respiratory symptoms each occurred in less than 2% of children. Prolonged sedation ( greater than 2 h) was not encountered in our series. Sedation was successful in producing motion free CT examinations, so that in 303 (93%) of the cases, no repeat CT scans were needed. We conclude that high dose oral chloral hydrate provides safe and effective sedation for children undergoing CT.
