The overall assessment of aspiration risk may not rely on ASA Physical Status alone, as many of the comorbidities that qualify patients for a higher ASA Physical Status score may be unrelated to delayed gastric emptying or aspiration risk (for example, poorly controlled hypertension). For these guidelines, the primary outcomes of interest are pulmonary aspiration and the frequency or severity of adverse consequences associated with aspiration (e.g., pneumonitis). Practice Guidelines for Preoperative Fasting and the Use of Pharmacologic Agents to Reduce the Risk of Pulmonary Aspiration: Application to Healthy Patients Undergoing Elective Procedures: An Updated Report by the American Society of Anesthesiologists Task Force on Preoperative Fasting and the Use of Pharmacologic Agents to Reduce the Risk of Single trials reported less hunger73 and greater satisfaction80 among patients drinking protein-containing clear liquids compared with patients drinking other clear liquids (very low strength of evidence).
