There is an increased risk associated with procedural sedation of infants younger than 6months of age. The use of propofol for radiologic imaging of this age group is not well studied. We hypothesize that adverse events are higher in the infant population receiving propofol for radiologic imaging. A retrospective chart review was undertaken of 304 infants younger than 6months old who received propofol for procedural sedation from October 2012 to February 2015. Patient demographics, propofol dosing, sedation-related adverse events and interventions were collected. Serious adverse events were defined as laryngospasm, aspiration, the need for admission, cardiac arrest or death. Procedural sedation for radiologic imaging was successful in 301/304 (99%) of infants using propofol. Of these 304 patients, 130 (42.8%) patients were female, and 240 of the 304 (79%) were between 3 and 6months of age. The majority of patients (172/304 [56.6%]) were American Society of Anesthesiologists-Physical Status Class II. There were 57 sedation-related, minor adverse events in 39 out of 304 (12.8%) patients. Thirteen of the 304 (4.3%) patients had 14 serious adverse events, with airway obstruction the most common. Eighty interventions were required in 56/304 (18.4%) patients. The most common interventions were continuous positive airway pressure (CPAP) in 25/304 patients (8.2%) and jaw thrust in 15/304 (4.9%). The median induction propofol dose was 4.7mg/kg. A need for an increase in the propofol infusion rate during the procedure was noted in 162/304 (53.3%) infants. No significant predictors of sedation-related adverse events were detected. Propofol can be used for radiologic imaging of infants younger than 6months of age with a high success rate. Practitioners should be mindful of significantly higher dosing requirements and a higher incidence of airway events, which can be easily identified and managed by a team of experienced sedation providers.
