Patients quick earlier than surgical procedure to forestall meals from stepping into their lungs whereas they’re underneath — a critical concern that may result in lung an infection. However for these taking a category of therapies that embrace the extensively well-liked Ozempic and Wegovy, fasting is probably not sufficient to make sure an empty abdomen.
The American Society of Anesthesiologists issued steerage Thursday recommending that sufferers cease taking this class of therapies, referred to as GLP-1 medication, earlier than present process surgical procedure.
Although there may be restricted knowledge on how these medication have an effect on folks having surgical procedure, there are considerations — primarily based on anecdotal reviews — that delayed abdomen emptying attributable to these medication might improve the danger of regurgitation and meals aspiration into lungs when sufferers are on anesthesia, the group mentioned.
GLP-1 medication for kind 2 diabetes and weight problems have exploded in reputation for his or her means to considerably reduce folks’s weight. They mimic the consequences of the glucagon-like peptide 1 hormone that assist folks really feel full after consuming. The category of therapies, which embrace Novo Nordisk’s Ozempic and Wegovy and Eli LIlly’s Mounjaro, have gastrointestinal uncomfortable side effects like nausea, vomiting and delayed abdomen emptying.
Michael Champeau, president of the anesthesiologist group, mentioned they’ve heard anecdotes similar to docs performing endoscopies in sufferers taking these medication and seeing meals within the abdomen, sufferers vomiting up meals earlier than surgical procedures regardless that they’d fasted, and sufferers who have been underneath anesthesia and had meals come up throughout surgical procedure.
Usually the group critiques intensive literature earlier than issuing formal pointers, however on this case, there have been few research, he mentioned. “We needed to only get some steerage on the market as a result of so many individuals had been involved in regards to the subject.”
The group’s assertion famous there are reviews that the gastric emptying results are diminished with long-term use of the medication, however Champeau mentioned there isn’t intensive sufficient knowledge but to specify how lengthy sufferers have needed to have been on the drug to be in danger.
“The connection between how lengthy one has been taking the drug and the way a lot residual gastric content material one has, I feel, is at this level unpredictable sufficient that we don’t wish to danger the affected person’s well being,” he mentioned.
Delayed abdomen emptying on GLP-1 medication might also have an effect on how effectively sufferers are in a position to take in different oral medicines they’re taking. The label for Lilly’s Mounjaro recommends sufferers taking oral contraception to change to a non-oral type or add an extra technique of contraception for the month after they begin taking the drug and after every dose escalation. Research confirmed that the drug’s impact on gastric emptying was biggest after the primary dose and diminished after subsequent doses, based on the label.
The anesthesiologist group mentioned that for folks present process pressing surgical procedures, docs ought to take precautions assuming that the affected person has a full abdomen.
For elective procedures, the group recommends that sufferers who take a each day dose of a GLP-1 drug ought to maintain the therapy the day of surgical procedure, and people who take a weekly dose ought to maintain it the week earlier than surgical procedure.

Some knowledge counsel that the presence of gastrointestinal uncomfortable side effects are linked to how a lot meals there may be within the abdomen.
If the affected person has no gastrointestinal signs, however the GLP-1 drug was not held, then docs ought to think about using an ultrasound to evaluate what’s of their abdomen, the group mentioned. If the abdomen is empty, then docs can proceed as typical, but when the abdomen is full or the ultrasound is inconclusive, then docs ought to think about delaying the process or including full abdomen precautions.
Anesthesiologists also needs to talk about the danger of regurgitation and meals aspiration with different docs concerned within the surgical procedure and the affected person, the group mentioned.
