Preoperative fasting in emergencies: choice for preventing aspiration pneumonitis

ABSTRACT
Preoperative fasting is prescribed for a certain period before operations or procedures in which patients are not allowed oral intake to prevent aspiration of gastric content. Fasting recommendations prohibit the consumption of a heavy meal for 8 hours, a light meal or milk for 6 hours, and breast milk for 4 hours, and permit the consumption of clear liquid until 2 hours before an operation. However, sometimes, in an emergency situation such as increased intra-cranial or intraabdominal pressure and other trauma, the recommended fasting time might not be an absolute policy for preventing the aspiration of gastric content because the disease or trauma itself causes changes on the esophageal sphincter pressure, volume of the gastric content, and pH of the gastric fluid. Preparation of a safe anesthetic technique and appropriate preoperative medications can be helpful in preventing aspiration pneumonitis in an emergency situation.
