AIRWAY COLLAPSIBILITY FOLLOWING A SINGLE INDUCTION DOSE OF KETAMINE WITH PROPOFOL AND PROPOFOL SEDATION IN PEDIATRIC PARTICIPANTS UNDERGOING MRI

Abstract

Background: Adequate sedation is required for pediatric participants receiving an MRI (magnetic resonance imaging)
console. Propofol is a commonly used sedative. Propofol is a commonly used sedative; nevertheless, at large dosages, it causes
upper respiratory collapse, which can be compensated for by ketamine.
Aim: The current study aims to compare the airway collapsibility following a single induction dose of ketamine with propofol-
to-propofol sedation in pediatric patients undergoing MRI.
Methods: The study evaluated 116 pediatric patients having MRI and were randomly separated into two groups. Group I
individuals were administered propofol bolus. followed by infusion and Group II subjects were given bolus propofol and
ketamine followed by propofol infusion. Upper airway diameters (APD and TD) and cross-sectional area (CSA) were
compared in both groups using MRI during expiration and inspiration.
