Patients quick earlier than surgical procedure to forestall meals from entering into their lungs whereas they’re below — a critical concern that may result in lung an infection. However for these taking a category of remedies that embody the broadly standard Ozempic and Wegovy, fasting might not be sufficient to make sure an empty abdomen.
The American Society of Anesthesiologists issued steerage Thursday recommending that sufferers cease taking this class of remedies, known as GLP-1 medicine, earlier than present process surgical procedure.
Although there may be restricted knowledge on how these medicine have an effect on individuals having surgical procedure, there are considerations — based mostly on anecdotal stories — that delayed abdomen emptying attributable to these medicine might enhance the chance of regurgitation and meals aspiration into lungs when sufferers are on anesthesia, the group stated.
GLP-1 medicine for kind 2 diabetes and weight problems have exploded in recognition for his or her capability to considerably reduce individuals’s weight. They mimic the consequences of the glucagon-like peptide 1 hormone that assist individuals really feel full after consuming. The category of remedies, which embody Novo Nordisk’s Ozempic and Wegovy and Eli LIlly’s Mounjaro, have gastrointestinal unwanted side effects like nausea, vomiting and delayed abdomen emptying.
Michael Champeau, president of the anesthesiologist group, stated they’ve heard anecdotes corresponding to docs performing endoscopies in sufferers taking these medicine and seeing meals within the abdomen, sufferers vomiting up meals earlier than surgical procedures despite the fact that they’d fasted, and sufferers who had been below anesthesia and had meals come up throughout surgical procedure.
Sometimes the group opinions intensive literature earlier than issuing formal pointers, however on this case, there have been few research, he stated. “We needed to only get some steerage on the market as a result of so many individuals had been involved concerning the difficulty.”
The group’s assertion famous there are stories that the gastric emptying results are decreased with long-term use of the medicine, however Champeau stated 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 believe, is at this level unpredictable sufficient that we don’t need to threat the affected person’s well being,” he stated.
Delayed abdomen emptying on GLP-1 medicine may have an effect on how nicely sufferers are in a position to soak up different oral drugs they’re taking. The label for Lilly’s Mounjaro recommends sufferers taking oral contraception to modify to a non-oral type or add a further 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 best after the primary dose and diminished after subsequent doses, in keeping with the label.
The anesthesiologist group stated that for individuals 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 day by day dose of a GLP-1 drug ought to maintain the remedy the day of surgical procedure, and those that take a weekly dose ought to maintain it the week earlier than surgical procedure.
The group additionally stated that if the affected person is experiencing gastrointestinal signs like extreme nausea, vomiting or belly ache or bloating, that docs ought to think about delaying the surgical procedure. Some knowledge recommend that the presence of gastrointestinal unwanted 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 stated. 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 must also talk about the chance of regurgitation and meals aspiration with different docs concerned within the surgical procedure and the affected person, the group stated.
