Does a 3-point sonographic grading system of the gastric antrum correlate with predicted gastric volume in fasted surgical patients?
A proposed 3-point sonographic grading system of the gastric antrum may serve as a biomarker for perioperative aspiration risk.
We propose a 3-point grading system based exclusively on qualitative sonographic assessment of the gastric antrum that correlates well with predicted gastric volume. This grading system could be a promising "biomarker" to assess perioperative aspiration risk. Before it can be applied widely to clinical practice, this diagnostic tool needs to be further validated and characterized.
