Intervention1: Nasopharyngeal airway: Children with nasopharyngeal airway Control Intervention1: No Nasopharyngeal Airway: Children without nasopharyngeal airway

Eligibility

Inclusion criteria

Inclusion criteria: Children in the age group 1 to 10 years of physical status ASA I and II scheduled for Magnetic Resonance Imaging under deep sedation

Exclusion criteria

Exclusion criteria: 1. Children with Difficult airway 2. Children with adenoid enlargement 3. Children with congenital heart disease

Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
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.	—
