Increasing depth of sedation may be associated with airway obstruction. A neck collar supporting the mandible and maintaining the head in slight extension may be beneficial in maintaining airway patency.\n <\/jats:p>\n <\/jats:sec>\n \n Aim of the study<\/jats:title>\n \n Primary aim<\/jats:italic>\n : To assess upper airway size with and without a neck collar during pediatric\n MRI<\/jats:styled-content>\n sedation with propofol\u2013midazolam.\n Secondary aim<\/jats:italic>\n : To evaluate complications encountered during the procedure.\n <\/jats:p>\n <\/jats:sec>\n \n Materials and Methods<\/jats:title>\n \n Sixty patients aged 2\u20134\u00a0years scheduled for\n MRI<\/jats:styled-content>\n of the brain were selected. They were sedated with intramuscular midazolam 0.1\u00a0mg\u00b7kg\n \u22121<\/jats:sup>\n 30\u00a0min before the procedure. Patients were sedated with i.v. propofol 1\u00a0mg\u00b7kg\n \u22121<\/jats:sup>\n and continued with 50\u2013100\u00a0\u03bcg\u00b7kg\n \u22121<\/jats:sup>\n \u00b7min\n \u22121<\/jats:sup>\n . T1 3D fast\u2010field echo axial sequence from the nasopharyngeal roof to subglottic region was taken with and without application of a neck collar. Airway dimensions were measured and analyzed at the base of the tongue, soft palate, and at the epiglottis.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n At the base of the tongue and soft palate, the cross\u2010sectional area (\n CSA<\/jats:styled-content>\n ) and the anteroposterior diameter of the airway were respectively statistically significantly higher when the neck collar was applied. The\n CSA<\/jats:styled-content>\n at the epiglottis was significantly less with application of the neck collar. Complications were not significantly different between the two sequences.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Application of a soft neck collar in children aged 2\u20134\u00a0years may enhance the retropalatal and retroglossal airway dimensions during pediatric sedation in the supine position.<\/jats:p>\n
