For decades, anesthesiologists advised patients non to eat or beverage at all afterwards midnight the dark before their surgery—a guideline referred to in the medical world as "NPO after midnight."
Simply experts are now revisiting the sometime standard. New research suggests that the "NPO later on midnight" dominion is unnecessarily strict for patients scheduled to undergo surgery. In both 1999 and 2011, the American Society of Anesthesiologists issued NPO guidelines that permitted the consumption of articulate liquids until two hours before surgery for all healthy patients undergoing elective procedures requiring general anesthesia, regional anesthesia or sedation/analgesia.
Despite the contempo recommendations, many anesthesiologists proceed adhere to "NPO past midnight" rule for all surgical patients.
"We have good prove that drinking articulate liquids until two hours before surgery is safe, but nosotros continue to have this dogma about non eating or drinking anything afterward midnight, which is just a number picked out of the air," said Anesthesiologist Joyce Wahr, Dr., FAHA, the director of the new University of Minnesota Health Preoperative Assessment Heart (PAC).
Nosotros spoke with Wahr to discuss the new take on the longtime arroyo.
Why have doctors traditionally recommended that patients fast earlier surgery?
In the 1950s, 2 research papers were published regarding pregnant women who received heavy anesthesia during commitment, then died when they aspirated the contents of their stomachs. As a outcome, anesthesiologists were very concerned near patients having any nutrient in their stomach before receiving anesthesia. When patients receive general anesthesia, they are unable protect their own airways or keep them clear. For that reason, the care squad needs to prevent the contents of the stomach from entering the lungs. Today, nosotros employ an endotracheal tube to accomplish that, only the studies from the 1950s were based on outdated anesthesia techniques. Doctors at the time simply put a mask on the patient's face up and used ether, which makes many people sick.
What changed?
Around 2000, there was a large review of 30 or so separate studies. The review demonstrated that patients drinking fluid until ii hours earlier surgery really had emptier stomachs during the procedure.
Many patients go into surgery in the afternoon and are therefore required to get 18 hours without food and potable under the old standards. Clearly, the guidelines take to be individualized for each patient and the time of the surgical process. This idea has been the official practice of the American Gild of Anesthesiologists since 1999, simply there'due south however some stigma attached to information technology.
What kind of fluids are we talking well-nigh that are OK to swallow before surgery?
Clear liquids—something you tin can see through. Some options include apple tree juice, Gatorade, black coffee, or tea without any milk or cream.
Are certain foods besides being considered?
Only a few studies have been published well-nigh a patient'south ability to consume food earlier a process. For that reason, we still ask patients to refrain from drinking milk or eating any nutrient for 8 hours prior to the surgery. Milk is a protein and withal has a lot of fatty in information technology, and then the digestive organization takes longer to process it than other fluids. If a patient wants to eat earlier the procedure, we recommend toast and crackers, and we recommend that this be eaten viii hours before the process.
What differences do you see in patients based on the unlike approach?
A number of studies testify that patients do much better if they're allowed to beverage up to two hours before surgery. They utilize less IV fluid, and depending on what they drink, they accept better metabolism. It'southward also less difficult to control a patient'south sugar levels following surgery.

How does the Preoperative Assessment Center comprise this research—and other advancements—into its preoperative care?
As anesthesiologists, we know that improve preparation allows for a better recovery. We're always incorporating that idea into our care.Nosotros advise patients about being active and getting upwardly and moving. We talk about "prehabilitation"—instead of rehabilitation. In other words, they should stay active before surgery, so that they're in practiced condition entering the procedure. Surgery is like running a marathon. Yous put a lot of stress on your body, then it helps to do a little training program beforehand to prepare your body. We likewise have these conversations before the procedure. That mode, after surgery, patients are prepared and informed, and nosotros are not trying to train a patient who is groggy or in pain.
