Why is the patient kept NPO until bowel sounds are heard after GI surgery?

• A. Bowel sounds are an indication that peristalsis has resumed.
• B. There is a risk of emesis following gastro-intestinal surgery.
• C. Eating any food will disturb the operative site.
• D. It is intended to prevent nausea associated with anaesthetic administration.

Answer: (B)

After GI surgery, the stomach and intestines may not be moving yet and protective airway reflexes from anesthesia can be reduced. Feeding too soon raises the risk that vomiting or regurgitation could occur and be aspirated into the lungs. Waiting until bowel sounds are heard indicates that GI motility is returning and the risk of regurgitation/aspiration decreases, making it safer to resume oral intake. The focus isn’t primarily on preventing anesthesia-related nausea, but on preventing emesis and potential aspiration in a patient with a sluggish GI tract and anesthetic effects.
