“In this study, there was no association between fasting duration and any type of adverse event. These findings do not support delaying sedation to meet established fasting guidelines”.
An observational study sparse on details on what sedation was used, depth of sedation and the procedures in ER. And the rate of vomiting was 5% but they evidently mostly got away with it. A study unlikely to convince anesthesiologists to abandon ASA and other fasting guidelines in this Pediatric population (or adults).
