GERDS/PUD/Gall bladder disease Flashcards
(105 cards)
occurs when the mucosal barrier breaks down and an inflammatory response occurs within the esophagus because of the acid content of the reflux matter
Gastroesophageal Reflux Disease
replacement of the squamous cell epithelium of the lower esophagus with new tissue that is more resistant to acid but is considered premalignant.
Chronic gastroesophageal reflux can lead to::
Barrett’s epithelium
narrowing of the esophageal opening. this may lead to progressive difficulty in swallowing.
Esophageal stricture
A decrease of the lower esophageal sphincter tone.
-delayed gastric emptying.
-older adults experience impaired esophageal peristalsis
Conditions that elevate intra-abdominal pressure:
ie. obesity, pregnancy, heavy lifting, hiatal hernias, wearing tight belts or girdles
Factors that increase chances for GERDS
Foods/beverages Smoking Medications Hormones Peppermint, spearmint NG tube placement
Factors contributing to decreased lower esophageal sphincter pressure: GERD
Heartburn (dyspepsia) Regurgitation Eructation (belching) Water brash Nocturnal cough Flatulence Dysphagia (difficulty swallowing) Chest pain Odynophagia (painful swallowing) Chronic cough-at night Nausea
Physical Assessment/Clinical Manifestations
Hx and presents of predisposing factors
24 hr. ambulatory esophageal pH monitoring
Esophagogastroduodenoscopy (EGD)
Esophageal manometry (pressure, look at esoph.spincter; tight or loose)
Barium Swallow test
Diagnosing GERDS
Relief of symptoms
Treatment of Esophagitis
Prevention of Complications such as strictures
Purpose of nonsurgical management of GERDS
Nutrition Therapy
Lifestyle Changes
Drug Therapy
Patient and Family Teaching for GERDS
-Limit or eliminate foods that decrease LES pressure
-Drink fluids with meals; helps break it up
-Mastication and eat more frequent meals; 6 sm. meals a day, more you chew, quicker digestion
[Fats are slower to digest, carbs are the quickest (glucose)] (carbs, proteins, then fats)
-Avoid eating for at least 3 hours before going to bed. [slower to digest, produces more acid, increase chance of reflux]
-Avoid alcohol and tobacco (nicotine);
Nutritional therapy; relieve symptoms for patients with mild GERDS
- Elevate the head of the bed 6 to 12 inches. Never sleep on flat bed!! Sleep right side-lying position (no pressure on stomach)
- Lose weight if overweight.
- Avoid wearin constrictive clothing.
- Avoid heavy lifting, straining, and working in a bent-over position.
- Avoid drugs that lower the LES pressure such as oral contraceptives-, anti-cholinergic agents, sedatives, NSAIDS, calcium channel blockers
Lifestyle changes for GERDS
Antacids
Histamine 2 receptor antagonists
Proton Pump inhibitors
Pharmacology regime for GERDS management
- inhibit gastric acid secretion
- accelerate gastric emptying
- protect the gastric mucosa
GERD: These drugs have one or more of the following functions: Antacids Histamine 2 receptor antagonists Proton Pump Inhibitors
Promote the gastric mucosal defense mechanisms by stimulating the production and secretion of;
- Mucus; protective barrier against HCL
- Bicarbonate: Helps buffer acidic properties of HCL
- Prostaglandins: Prevents activation of proton pump!!
- Increases the LES pressure
Antacids: Mechanism of Action
GERDS
Commonly used Antacids include:
Aluminum Salts (constipation) and/or Magnesium Salts (diarrhea)
*Calcium salts (tums helps to produces kidney stones)
*Sodium bicarbonate; (Alkasetlzer)
*Alginates-Gaviscon; lowers pH, foam @ mouth, but baths the stomach.
Reduces heartburn symptoms
GERDS
- Use with caution with other medications due to the many drug interactions, and possible reduced drug absorption.
- Antacids may cause premature dissolving of entero-coated medications, resulting in stomach upset.
- Take antacids 1 hour before and/or two to three hours after ea. meal.
Antacids: Nursing Implications
GERDS
Block histamine (H2) at the receptors of acid producing parietal cells. -Thus the production of hydrogen ions is reduced, resulting in decreased production of HCL..
H2 Antagonists: Mechanism of Action
Zantac
GERDS
Take at least 1 hr before or after antacid.
Usually requires more than one dose a day.
Nursing Implications: h2 Antagonists; Gerds
Reduce acid secretion -Zantac (ranitidine) -Pepcid (famotidine) More potent, longer-acting drugs but produce fewer side effects than axid *Nizatidine (AXid) *cimetidine (Tagamet)
Histamine 2 receptor antagonists
GERDS
-too much, GERDS constant bleeding
-body will use pancreatic enzymes in duodenum instead of HCL acid
***Aluminum hydroxide (Alu-Cap, AlternaGEL)
Neutralize stomach acid secretions. Used for gastroesophageal reflux, peptic ulcers, gastritis.
Antacids GERDS
- esomeprazole (Nexium)
- lansopraxole (Pravacid)
- omeprazole (Priosec)
- pantoprazole (Protonix!!!)
- rabeprazole (AcipHex)
Blocks gastric acid secretions by inhibiting the hydrogen-potassium-ATPase pump in the stomach. Proton pump inhibitors are the drugs of choice for severe GERD!!***
Admin 30 min before breakfast and HS if BID.
Monitor liver values
Proton Pump Inhibitors; GERD
*cimetidine (Tagamet)
*ranitidine (Zantac)
*famotidine (Pepcid)
*nizatidine (Axid)
Blocks histamine, thus reducing the release of hydrogen ion secretion from the parietal cells, causing the pH to increase in the stomach.
**Used for acid-r/t disorders including gastroesophageal reflux and peptic ulcer disease.
H2-Receptor Blockers
Admin in 20-100 ml of solution over 15-30 mins. Do not mix with other drugs. Can cause dyshythmias and hypotension with rapid admin.
given po or iv
**Donot give antacid within 1 hr before or after admin of H2. receptor blocker.
Gi stimulate or prokinetic agent.
*metoclopramide (Reglan)
- Increase the tone of the lower esophageal sphincter and stomach contractions to move food through the stomach and sm. intestine.
- Used for gastroesophageal reflux and gastroparesis.
*Unlabeled use includes Hiccups.
Promotiliy Agents; GERDS
take 30 mins AC and HS.
Avoid using with intestinal obstruction or lactating.
EPS symptoms, diarrhea, possibe HTN crisis
Use cautiously and in reduced dosages in patients with renal disease. Dysrhythmias are common.
Axid (nizatidine); h2 receptor blocker
