From the Guidelines
To perform a barium meal, the patient is administered a barium sulfate suspension orally, and then positioned under fluoroscopy to evaluate the esophagus, stomach, pylorus, and duodenum 1.
Key Steps
- The barium sulfate suspension is used to visualize the upper gastrointestinal tract, specifically the esophagus, stomach, pylorus, and duodenum to the duodenal jejunal junction 1.
- The procedure involves obtaining serial images at 1-5 minute intervals over a period of time to assess the movement of the barium sulfate suspension through the upper gastrointestinal tract.
- Meticulous technique is warranted to avoid inaccurate interpretations, which can be caused by factors such as redundant duodenum, bowel distension, and jejunal position 1.
- The barium meal procedure is considered a reference standard for evaluating malrotation, but it is not without limitations, including potential false-positive and false-negative interpretations 1.
From the Research
Barium Meal Procedure
There are no research papers to assist in answering this question. The provided studies do not mention the procedure for a barium (Ba) meal.
- The studies provided focus on various topics such as the trough:peak ratio of antihypertensive drugs 2, intravenous iron sucrose dosage 3, oral morphine dosing in children 4, efficacy and safety of sustained release diltiazem formulation 5, and calculation of drug doses in solution 6.
- None of these studies provide information on the procedure for a barium meal.
