WHY NPO AFTER SURGERY

NPO is Latin for "nil per os", and it means "nothing by mouth". Surgeons order NPO to patients before and after any surgery. They do so to prevent any complications during and after surgery.

What is NPO after surgery?

NPO is a medical term used to describe the period of time when a person is not allowed to eat or drink anything by mouth. This is typically done before and after surgery to prevent complications, such as aspiration pneumonia or bowel obstruction.

Why should you be NPO before surgery?

There are several reasons why your surgeon may order you to be NPO before surgery. These reasons include:

To prevent aspiration pneumonia

Aspiration pneumonia can occur when food or liquid enters the lungs. This can lead to a serious infection. When you are asleep during surgery, your gag reflex is suppressed. This means that you are more likely to aspirate food or liquid into your lungs if you have eaten or drunk recently.

To prevent bowel obstruction

A bowel obstruction is a blockage in the intestines. During surgery, the bowels are often manipulated. This can increase the risk of a bowel obstruction if there is food or liquid in the intestines.

To prevent nausea and vomiting

Nausea and vomiting are common side effects of surgery. Eating or drinking before surgery can make these side effects worse.

What can you do if you are NPO before surgery?

If you are NPO before surgery, there are a few things you can do to make the process easier.

Follow the instructions of your surgeon.

Your surgeon will give you specific instructions about when to stop eating and drinking before surgery. Be sure to follow these instructions carefully.

Drink plenty of fluids.

You can drink clear liquids, such as water, juice, and tea, up until two hours before surgery. Avoid drinking sugary drinks, such as soda and juice, as these can cause nausea and vomiting.

Eat a light meal.

You can eat a light meal, such as a salad or a sandwich, up to six hours before surgery. Avoid eating heavy or greasy foods, as these can also cause nausea and vomiting.

What happens when NPO is broken before surgery?

If you break NPO before surgery, you may be at increased risk for complications. Tell your nurse or doctor immediately if you eat or drink anything after being told not to. Your surgery may be delayed or canceled as a result.

What can you do if you are NPO after surgery?

After surgery, you will typically be NPO for a few hours. This is to allow your stomach and intestines to rest and heal. Once you are able to tolerate fluids, you will be given clear liquids, such as water, juice, and tea. You will gradually be able to eat solid foods as your gut heals.
