OBJECTIVE: To assess the mean time to hypnosis, hemodynamic stability, and incidence of complications associated with the administration of 70mg/kg oral chloral hydrate in children scheduled for magnetic resonance imaging (MRI).
MATERIAL AND METHODS: Prospective study conducted from January 2000 to January 2020 in which 3132 patients aged between one day and 5 years underwent MRI under anaesthesia in an outpatient setting. The study population was divided into 4 subgroups: A) aged between one and 30 days; B) aged between one month and one year; C) aged between one and 3 years, and D) aged between 3 and 5 years. Study variables were: sex, age, type of examination, mean imaging time, mean time to awakening, heart rate before and after MRI, SatO2, and incidence of complications such as respiratory depression (SatO2 below 90%), agitation during the MRI or on awakening (intense crying lasting more than 2min), prolonged sedation measured on the Steward scale, and nausea and/or vomiting during the MRI, on awakening, or at home.
RESULTS: No notable hemodynamic alterations were observed. The incidence of desaturation was .41%, awakening during the test was .16%, prolonged sedation was 1.08%, and agitated awakening was 1.46%. Nausea and vomiting at the end of the test had an incidence of .73%. The P value in all cases was <.05%.
CONCLUSIONS: Chloral hydrate at a dose of 70mg/kg continues to be suitable in sedation lasting no more than one hour for non-invasive procedures in children, and is associated with adequate haemodynamic stability with practically no side effects.
