The American Society of Anesthesiologists (ASA) published updated guidelines indicating that for a healthy patient undergoing an elective procedure, a minimum of only 2 hours is required for clear liquids. The total duration considered NPO varies based on the type of ingested material, with solids requiring a longer fasting period than clear liquids. Following these specific guidelines is critical for patient safety during sedation or general anesthesia.
