“…[ 12 ] concluded that a 1:3 ratio of ketamine with propofol achieves deep sedation and analgesia with rapid onset and the shortest recovery time. [ 13 14 ] Nonetheless, we used a 1:1 ratio of ketamine and propofol bolus only at the induction time, followed by propofol infusion for maintenance. It also decreased the incidence of postprocedure nausea and vomiting.…”

Background and Aims: Adequate sedation is essential for children undergoing magnetic resonance imaging (MRI) console. Propofol is commonly used for sedation, but it has the drawback of upper airway collapse at higher doses, which may be overcome by ketamine. This study was designed to evaluate the beneficial effect of ketamine on propofol in preventing airway collapse. Methods: Fifty-eight children undergoing MRI were randomised to Group P (propofol bolus dose followed by infusion or Group KP (bolus dose of ketamine and propofol followed by propofol infusion). The primary aim is to compare the upper airway cross-sectional area (CSA) and diameters (transverse diameter [TD] and anteroposterior diameter [APD]) obtained from MRI during inspiration and expiration. Results: Upper airway collapse as measured by delta CSA in mean (SD) [95% confidence interval] was statistically more significant between the two groups [at the soft palate level, 16.9 mm2 (19.8) [9.3–24.4] versus 9.0 mm2 (5.50) [6.9–11.1] (P = 0.043); at the base of the tongue level, 15.4 mm2 (11.03) [11.2–19.6] versus 7.48 mm2 (4.83) [5.64–9.32] (P < 0.001); at the epiglottis level, 23.9 (26.05) [14.0–33.8] versus 10.9 mm2 (9.47) [7.35–14.5] (P = 0.014)]. A significant difference was obtained for TD at all levels and for APD at the soft palate and base of tongue level. Conclusion: Adding a single dose of ketamine to propofol reduced the upper airway collapse significantly, as evidenced by the MRI-based measurements of upper airway dimensions, compared to propofol alone.

“…In line with the core outcomes in pediatric anesthesia and perioperative care, Yilmaz et al, in a randomized and double-blinded clinical trial, investigated whether a rigid neck collar could improve airway patency during MRI examination under propofol-based sedation in children. 12 The authors randomized 125 children to either a rigid neck collar in a supine position or only standard approach. All children were submitted to MRI examination, and measurements of airway dimensions were taken.…”
