Study Notes
GI Studies
- The barium transit time to the stomach is 5-10 minutes.
- Glucagon is used to relax smooth muscles of the GI tract in GI studies.
Body Habitus
- Individuals with thicker body parts are described as endomorphic.
- Asthenic body habitus is characterized by a slender build and is found in 10% of the population.
- Hyposthenic body habitus is characterized by a thin, delicate build and is found in 5% of the population.
Esophageal Conditions
- Achalasia is characterized by a failure of the lower esophagus sphincter muscle to relax.
- The most common cause of esophagitis is reflux esophagitis.
- Esophageal cancer is best diagnosed using endoscopy and biopsy.
- Photodynamic therapy involves laser-activated chemicals to destroy esophageal tumors.
- Zenker's Diverticulum is a large outpouching of the esophagus just above the upper esophageal sphincter.
Varices and Positioning
- If varices are suspected, the patient should be placed in the Trendelenburg position (head down).
Medications
- Metoclopramide (Maxolon) enhances gastric peristalsis to aid in the passage of contrast material during GI studies.
- Buscopan is used to relax smooth muscles of the GI tract in GI studies.
- Medications like atropine and anticholinergics have side effects including blurred vision and dry mouth.
Barium Suspension
- The weight measure for barium in 100 grams of suspension is 30-40%.
- The weight measure for barium in 100 ml of suspension is 30-40%.
- UGI Single contrast typically uses a 50-70% barium suspension.
- UGI Double contrast typically uses a 100-150% barium suspension.
