OBJECTIVES: The purpose of this study was to determine the total propofol dose (mg/kg) for non-emergent pediatric procedural sedation and evaluate dosing differences with regard to a patient's sex, age, and body mass index. Adverse events were recorded and evaluated to determine whether certain patient groups were at a higher risk than others. METHODS: This study was a retrospective observational pilot study including patients 0 to 18 years of age admitted between January 2008 and November 2009 for non-emergent gastrointestinal endoscopic procedures or radiologic imaging, who received propofol for procedural sedation. Data gathered included sex, age, height, weight, chronic medical conditions and medication use, concomitant anesthetic gas, preprocedure midazolam, procedure length, propofol dose in mg/kg, other medications administered during procedure, and adverse events that occurred. Comparisons between adverse event groups and categories of baseline characteristics were made using the Wilcoxon signed-rank, Kruskal-Wallis nonparametric and Pearson's chisquare tests, as appropriate. RESULTS: A total of 101 patients met inclusion criteria and were included in the analysis. The mean dose of propofol required for female patients was 3.7 mg/kg versus 3.4 mg/kg for males (p=0.3). The mean dose of propofol for patients ≤9 years, 10 to 12 years, and >12 years was 3.2, 3.9, and 3.9 mg/kg, respectively (p=0.25). The mean dose of propofol for underweight, healthy weight, overweight, and obese patients was 4.2, 3.9, 3.6, and 2.6 mg/kg, respectively (p=0.38). Hypotension occurred in 42.6% of patients, and bradycardia occurred in 13.9% of patients. CONCLUSIONS: There were no differences in dose requirements based on sex or age. The difference in dosing between different body weight categories was not statistically significant. The dose of propofol was higher in patients that experienced bradycardia and hypotension, but there was no statistical significance. Given the above, future studies with larger sample sizes should be conducted to establish if statistical significance exists.
