Glucagon-like peptide-1 (GLP-1) receptor agonists are approved by the Food and Drug
Administration for treatment of type 2 diabetes mellitus and cardiovascular risk
reduction in this cohort (see table).1 In addition, GLP-1 receptor agonists are also used
for weight loss. Several entities have recommended to hold these drugs either the day
before or day of the procedure. 2-7 For patients on weekly dosing, it is recommended to
hold the dose for a week.8
The GLP-1 agonists are associated with adverse gastrointestinal effects such as
nausea, vomiting and delayed gastric emptying (see table). The effects on gastric
9,10
:
emptying are reported to be reduced with long-term use.9,10 This is most likely through
rapid tachyphylaxis at the level of vagal nerve activation.11 Based on recent anecdotal
reports, there are concerns that delayed gastric emptying from GLP-1 agonists can
increase the risk of regurgitation and pulmonary aspiration of gastric contents during
general anesthesia and deep sedation.12-14 The presence of adverse gastrointestinal
symptoms (nausea, vomiting, dyspepsia, abdominal distension) in patients taking GLP-1
agonists are predictive of increased residual gastric contents.12
The use of GLP-1 agonists in pediatrics has primarily been reported for the
management of type 2 diabetes mellitus and obesity. The published literature on GLP-1
agonists in pediatrics is predominantly from pediatric patients 10-18 years old;
concerns are similar to those reported in adults. During the conduct of general
anesthesia/deep sedation, children on GLP-1 agonists have similar gastrointestinal
adverse events at a rate similar to adults.
For patients on daily dosing consider holding GLP-1 agonists on the day of the
procedure/surgery. For patients on weekly dosing consider holding GLP-1
agonists a week prior to the procedure/surgery.
If GLP-1 agonists prescribed for diabetes management are held for longer than
the dosing schedule, consider consulting an endocrinologist for bridging the
antidiabetic therapy to avoid hyperglycemia.
If the patient has no GI symptoms, and the GLP-1 agonists have been held as
advised, proceed as usual.
If the patient has no GI symptoms, but the GLP-1 agonists were not held as
advised, proceed with ‘full stomach’ precautions or consider evaluating gastric
volume by ultrasound, if possible and if proficient with the technique. If the
stomach is empty, proceed as usual. If the stomach is full or if gastric ultrasound
inconclusive or not possible, consider delaying the procedure or treat the patient
as ‘full stomach’ and manage accordingly. Discuss the concerns of potential risk of
regurgitation and pulmonary aspiration of gastric contents with the
proceduralist/surgeon and the patient.
