Introduction:

“Nil by Mouth” (NBM) refers to a medical order where a patient is instructed not to consume anything by mouth. This can be due to various reasons, such as the need for surgery, gastrointestinal issues, or the risk of aspiration. It is critical that both healthcare professionals and patients understand the reasons and protocols around NBM orders to ensure patient safety.

What is Nil by Mouth (NBM)?
NBM is a medical instruction given to restrict a patient from ingesting food, fluids, or medications orally.

Why is NBM Important?
NBM orders are crucial to prevent complications like aspiration (where food or liquid enters the lungs), or to ensure that the gastrointestinal tract is not disturbed before a procedure. NBM is also important when preparing for certain diagnostic tests or surgeries that require an empty stomach.

When is NBM used?
- Pre-surgery: to reduce the risk of aspiration during anesthesia.
- Gastrointestinal issues: conditions like bowel obstruction or certain surgeries.
- Risk of aspiration: for patients with difficulty swallowing or those who are unconscious.

Monitoring NBM patients:
It’s important to monitor hydration and nutrition carefully. IV fluids and electrolytes are typically administered, and alternative routes for medication may be needed.
