-
Upper GI Series
- Radiographs of the lower esophagus, stomach and duodenum using barium sulfate.
- Detects abnormalities, tumors or ulcerative lesions.
-
Upper GI Series Interventions
- NPO
- Avoid smoking
- Expect light colored stool 72 hrs post
- Hardened barium impaction
- Encourage Fluids
- Milk of magnesia unless contraindicated
-
Gastrografin
Water soluble product used in place of barium for patients susceptible to bleeding from the GI system.
-
Tube Gastric Analysis
Aspiration of stomach contents to determine the amount of acid produces by the parietal cells.
-
Tube Gastric Analysis Interventions
- NO Anticholinergic meds 24 hrs before
- NPO
- No smoking (nicotine stimulates gastric secretions)
- Insert NG tube, aspirate, label and send specimen immediately.
-
Esophagogastroduodenoscopy
- Direct visualization of the upper GI using a fiberoptic scope.
- Detects tumors, varices, inflammation, hiatal hernia, polyps ulcers, H. pylori, strictures and obstructions.
- Removal of polyps, coagulation of GI bleeding, sclerotherapy, dilation, biopsy.
-
Esophagogastroduodenoscopy Interventions
- NPO
- Consent
- Preop checklist
- Vital signs
- Asses for allergies
- Remove dentures
- Sedative is given and Pharynx is anesthetized
- NPO until gag reflex returns
- Assess for symptoms perforation (pain, tenderness, guarding, bleeding,)
-
Capsule Endoscopy
- Camera in a capsule is swallowed to visualize the GI tract
- Used to visualize, diagnose disease, and identify sources of GI bleeding
- Takes 57000 images during 8 hrs, relays images to a data recorder worn on a belt.
-
Capsule Endoscopy Interventions
- NPO until 4-6 hours later
- 8 hours after swallowing patient has the device removed
- Peristalsis causes passage of camera.
-
Esophageal Function Studies
- Bernstein Test , an Acid-perfusion test
- Helps differentiate esophageal pain from esophageal reflux from angina pectoris
-
Esophageal Function Studies Interventions
- Avoid sedating
- NPO 8 hrs before
- Withhold meds that will interfere with acid production (antacids and analgesics)
-
Occult Blood Examination
- Blood that is obscured or hidden from view
- Tests are also called Guaiac, Hemoccult and Hematest.
- Detects blood from GI tumors, ulcerations of the upper or lower GI, blood swallowed from oral or nasopharyngeal origin.
-
Occult Blood Interventions
- Keep Specimen free of urine or toilet paper.
- Don gloves and use tongue blade.
- No organ meat 24-48 hrs before test.
- Label (pt name, nurse initials, time & date of collection)
- Send to lab immediately
-
Lower GI Series (Barium Enema)
- Radiographs of the colon demonstrate presence of polyps, tumors, diverticula, and positional abnormalities.
- Barium sulfate is used
-
Lower GI Series Barium Enema Interventions
- Administer cathartics
- Administer cleansing enema PM before or AM of BE
- Milk of magnesia after
- Assess evacuation of Barium
- Barium my cause hardened impaction
- Light colored stool
-

- ALT 8-20
-
Albumin
- Magnet to water
- protein produced by liver & from the diet
- Decreases with liver damage
- 3.5- 5.0
-
Ammonia
- Converts to urea
- Increases with Liver damage
- 15-110
-
Pancreatic enzymes
- Increases with Pancreatitis
- Amylase 56-90
- Lipase 0-110
