Nausea, vomiting, and aspiration pneumonia in “non-fasting” patients undergoing non-emergent contrast-enhanced computed tomography scan and relation to food intake

Objectives Traditionally, fasting before a contrast-enhanced computed tomography (CECT) scan was considered necessary due to the concerns of nausea, vomiting, and aspiration pneumonia. As per the recent international guidelines, fasting is not recommended prior to routine CECT; and with the use of non-ionic iodinated contrast media (ICM), the frequency of adverse reactions has decreased significantly. Our aim is to prospectively evaluate the effect of non-fasting on the occurrence of nausea, vom
