Although aspiration is uncommon in healthy ASA Physical Status I or II patients (estimated 1.1/10,000 adults and 1.3/10,000 children),24 it may lead to pneumonitis, pneumonia, and airway obstruction.5,6 Of the aspiration events described in the 2021 ASA Closed Claims analysis of aspiration of gastric contents events, 57% of aspiration incidents resulted in death, and another 15% resulted in permanent severe injury.4 The rationale for preoperative fasting is to minimize gastric content, thereby lowering the risk of regurgitation and subsequent pulmonary aspiration. marc scott carpenter obituary. About Us; Staff; Camps; Scuba. Although the relationship between gastric volume and gastric emptying time with aspiration risk has not been demonstrated in adequately powered studies,7 most published studies have used these measures as intermediate outcomes. Healthy adult patients should be encouraged to drink up to 400ml of carbohydrate-containing clear liquids until 2h before an elective procedure to minimize potential harms of prolonged fasting, including hunger and thirst.
