Abstract
Background: There is an increased risk associated with procedural sedation of infants younger than 6 months of age. The use of propofol for radiologic imaging of this age group is not well studied.Objective: We hypothesize that adverse events are higher in the infant population receiving propofol for radiologic imaging.Materials and Methods: A retrospective chart review was undertaken of 304 infants younger than 6 months 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.Results: 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 6 months 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 4.7 mg/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.Conclusion: Propofol can be used for radiologic imaging of infants younger than 6 months 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.
