[Sedation with oral hydroxyzine and rectal chloral hydrate in pediatric MRI and CT].

AIM: To assess the efficacy and risks of oral hydroxyzine and rectal chloral hydrate to sedate children undergoing CT or MRI. PATIENTS AND METHODS: 110 children underwent 117 studies. Medical history, treatments, doses per kg of sedative drugs, study quality, sedation time and side effects were prospectively recorded. RESULTS: 25 minutes was the mean time necessary to put children to sleep, 59 minutes was the mean time of sedation 96% of studies were interpretable. 2 children showed transient side effects. CONCLUSION: This sedation regimen appeared efficient. However, its limitations and risks have to be known by radiologists. Sedation-related problems also have to be considered by hospital managers when a new CT or MR equipment is being acquired.
