BACKGROUND: The quality of MRI and CT depends largely on immobility of the patient during the procedure, which is often difficult to achieve without sedation in children below the age of 6 years.
OBJECTIVE: To assess the efficacy and safety of intravenous chlorpromazine sedation for repeated imaging in young children treated for cancer.
MATERIALS AND METHODS: From July 2003 to January 2007, information on children younger than 6 years of age having MRI or CT was prospectively collected. Forty-five minutes before the scan, a 10-min infusion of chlorpromazine 0.5 mg/kg was administered and managed by non-anesthetic staff. Patient monitoring included continuous measurement of pulse, respiration, oxygen saturation and arterial blood pressure. Procedure-related parameters and adverse events were documented. Sedation was considered successful when the procedure was completed and at least 95% of images were usable.
RESULTS: One-hundred-one procedures (82 MRI, 19 CT) were evaluated in 62 children, 3-74 months old. Adequate sedation was achieved in 96% of cases, with mean induction time, 22 min; mean duration of sleep, 72 min, and mean duration of procedure, 33 min. Mean time spent in the radiology unit was 104 min. Ninety-six percent of imaging procedures were successfully completed. No cardiac, respiratory, neurological or allergic complication occurred.
CONCLUSION: Intravenous chlorpromazine is safe and effective for procedural sedation in young children with cancer undergoing MRI and CT.
