Gastric Ultrasound Assessment for Preoperative Prandial State of Patients Taking Glucagon-Like Peptide-1 Receptor Agonists

August 1, 2023 updated by: Sudipta Sen, The University of Texas Health Science Center, Houston

Gastric Ultrasound Assessment for Preoperative Prandial State of Patients Taking Glucagon-Like Peptide-1(GLP-1) Receptor Agonists

The purpose of this study is to determine the type of gastric content and quantify the volume of liquid gastric contents using ultrasonography in patients on GLP-1 agonists that have presented for elective surgery and to determine if risk factors are associated with a higher gastric volume in patients on GLP-1 receptor agonists.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Group G: Patients taking GLP-1receptor agonists
Patient will be scanned first in the supine position and then in the right lateral decubitus position. The ultrasound probe will be placed in a sagittal plane in the epigastric region at the left subcostal margin and then will be moved past the midline in a fan like manner to the right subcostal region. Qualitative and quantitative assessments will be done.
Group C: Patients not taking GLP-1 receptor agonists (control group)
Patient will be scanned first in the supine position and then in the right lateral decubitus position. The ultrasound probe will be placed in a sagittal plane in the epigastric region at the left subcostal margin and then will be moved past the midline in a fan like manner to the right subcostal region. Qualitative and quantitative assessments will be done.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of subjects that are at risk for aspiration
Time Frame: end of ultrasound
Risk for aspiration is indicated by the presence of solids, thick fluid, or clear fluids >1.5ml/kg in the gastric antrum in the right lateral decubitus position
end of ultrasound
Number of subjects that are at low risk for aspiration
Time Frame: end of ultrasound
Low risk for aspiration is indicated by a collapsed gastric antrum or clear fluids <1.5ml/kg in the gastric antrum in the right lateral decubitus position.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Age
Time Frame: end of ultrasound
end of ultrasound
Number of participants that are male as indicated in the medical records
Time Frame: end of ultrasound

Body mass Index (BMI)
Time Frame: end of ultrasound
Body Mass Index (BMI) is calculated as the body mass in kilograms (kg) divided by the square of the body height in meters, and is expressed in units of kg/m2.
end of ultrasound
Physical status as assessed by the American Society of Anesthesiologists (ASA) physical status classification system
Time Frame: end of ultrasound
The classification ranges from American Society of Anesthesiologists (ASA)1 (normal healthy person ) to ASA IV (A patient with severe systemic disease that is a constant threat to life)
end of ultrasound
Number of participants with diabetes
Time Frame: end of ultrasound
end of ultrasound
Number of participants with reported nothing by mouth (NPO) status
Time Frame: end of ultrasound
end of ultrasound
Pain severity as assessed by the numeric scale
Time Frame: end of ultrasound
This is a 11 point scale with scores ranging from 0 (no pain) to 10 (worst imaginable pain)
end of ultrasound
Number of participants with Gastroesophageal reflux disease (GERD)
Time Frame: end of ultrasound
end of ultrasound
Number of participants that have use opioids preoperatively
Time Frame: end of ultrasound
end of ultrasound
