Excerpt

The routine request to fast patients before surgery [the so-called “Nothing Per Os (NPO) after midnight”] is based on the presumption that fasting will minimize gastric volume and acidity at the time of anesthetic induction so as to minimize the risk for (and eventually the consequences of) pulmonary aspiration [1]. The current guidelines [2] differentiate between solid food and clear liquid but apply only to “healthy” patients. …
