A module for sedation of children undergoing MRI: A Preliminary experience
Journal Title: JOURNAL OF MEDICAL COLLEGE CHANDIGARH - Year 2019, Vol 9, Issue 1
Abstract
INTRODUCTION: Magnetic resonance imaging (MRI) is widely used for diagnosing a wide range of conditions in children but MRI suite has a noisy and claustrophobic environment requiring motionless field. Therefore, sedation is essentially required in paediatric age group to encompass anxiety relief, pain control and reduction of motion artifact during MRI scan. MATERIAL AND METHODS: After pre-anaesthetic checkup and written informed consent from the parents of the patients, 20 children between age group of 1- 7 years undergoing MRI scan for various conditions were included in this case series. A module for sedation was employed using a combination of the subanaesthetic doses of propofol and thiopentone, while continuously monitoring heart rate and arterial oxygen saturation throughout. Onset of sedation, duration of action of first dose, total duration of MRI, total boluses needed, any need of airway intervention, complications like respiratory distress, nausea, vomiting etc were noted. RESULTS: Mean age of children was 4.15 ± 1.22 years and mean weight was 11.2± 2.37 Kg. Onset of sedation was in 67.55 ± 15.05seconds. Duration of action of first dose was 19.05 ± 7.53 min. None of the children required any airway intervention or had any complication. CONCLUSION: We conclude that using a combination of reduced doses of thiopentone and propofol for sedation in MRI can lead to efficient paediatric imaging without any adverse effects. This sedation module reduces the individual doses of the sedation drug leading to safe and secure practice in children undergoing MRI.
