- Primary Outcome Measures
Name Time Method To compare of the incidence of hypoxic episodes with or without nasopharyngeal airway placementTimepoint: The occurrence of desaturation i.e., decrease in oxyhaemoglobin saturation below 92% at any time from the administration of anaesthetic drugs to the end of the scan will be noted.
- Secondary Outcome Measures
Name Time Method To compare the number of interruptions during MRI study and reasons for interruptions (movement, apnea or hypoxia)Timepoint: Any interruptions during the MRI study i.e, from the time of administration of anaesthetic drugs to the end of the scan and the reason for interruption will be noted.;To compare the total dose of propofol used.Timepoint: The total dose of propofol given to each child will be calculated at the end of the MRI study.;To measure the distance between nasopharyngeal airway tip to epiglottis in MRI scan in children undergoing MRI head and neck.Timepoint: In children undergoing MRI of head and neck, the distance between the tip of nasopharyngeal airway and epiglottis is measured in the MRI scan and noted at the end of the scan.
