Is there an association between pulmonary aspiration, vomiting or any serious adverse event and the preprocedural fasting time?
The odds ratio of any adverse event did not increase significantly with each additional hour of fasting duration for both solids and liquids.
The guidelines set by the American Society of Anesthesiology for fasting include a minimum of 2 hours for clear liquids, 4 hours for breast milk, 6 hours for formula and light meals and 8 hours for solid meals containing fatty foods or meat.
This was a secondary analysis of a multicenter prospective cohort study of children 0-18 years who received procedural sedation in 6 Canadian pediatric emergency departments from 2010-2015. 6183 children were included with 99.7% meeting ASA 1 or 2 categories. 2974 patients did not meet the American Society of Anesthesiology fasting guidelines for solids and 510 patients did not meet the fasting guidelines for liquids. The overall incidence of adverse events was 11.6%. There were no cases of pulmonary aspiration. There was a total of 717 adverse events. 315 events were vomiting. Oxygen and vomiting were the most common adverse events.
