Causes:
Drug-related: NSAIDs (increased risk), anticoagulant therapy, corticosteroids, digitalis, alendronate (Fosamax).

Diet/environment: Alcohol use/spicy, irritating foods, caffeine, smoking, radiation

Helicobacter pylori and other infections

Diseases/Disorders: autoimmune gastritis, BURNS, Crohn’s Disease, hiatal hernia, PHYSIOLOGIC STRESS, bile reflux, renal failure, sepsis, SHOCK, hx of PUD, chronic debilitating disorders (muscle atrophy)

Female > 60 years old

Q

MANIFESTATION OF GASTRITIS (ACUTE & CHRONIC)
(ASSESSMENT) -RECOGNIZE CUES! What matters most ?

A

Acute: sudden, can be severe, usually reversible (SELF-LIMITING); Ex: abdominal discomfort, headache, lassitude, N/V, hiccuping –> can be cured

Chronic: intensified symptoms as deeper layers are damaged and lead to malabsorption of VITAMIN B12 (Cobalamin)
-Lack of intrinsic factor
ex: epigastric discomfort anorexia, heartburn after eating, belching, sour taste in the mouth, NAUSEA AND VOMITING, intolerance of some foods.

Q

GASTRITIS DIAGNOSTIC TESTING TYPES (9)

A

UPPER GASTROINTESTINAL (UGI) X-RAY - Barium swallow (contrast) (R/O gastric carcinoma)

ENDOSCOPY and BIOPSY [EGD w BIOPSY] Rapid urease test (R/O gastric carcinoma)

H. PYLORI TESTING

IMMUNOGLOBIN G (IgG)

UREA BREATH TEST (useful but may give false-negative results)

STOOL ANTIGEN TEST - can determine active infection (acute infection); most reliable

CBC for potential bleeding or B12 anemia r/t gastritis

FOBT- Blood test

FIT (Fecal Immunochemical Test)- more reliable- only detects human blood in the GI tract; screening test; also used for colon cancer testing

Q

GASTRITIS INTERVENTIONS/ MANAGEMENT OF GASTRITIS (ACUTE)
TAKE ACTION- WHAT WILL I DO?

A

ACUTE:
Identify cause: eliminate, prevent, or avoid it; tx involes diet/behavior modification.
-Discourage caffeinated beverages, alcohol, and cigarette smoking. Refer for alcohol counseling and smoking cessation.

Supportive therapy-
–NPO, REST, IV FLUIDS –>
(if severe)an NGT may be inserted to decompress and lavage if needed on an empty stomach d/t bleeding;

If due to ingestion of strong acid or alkali, AVOID EMETICS (ZOLOFT) AND LAVAGE d/t danger of perforation and damage to the esophagus –> goal is to neutralize

-REFRAIN FROM FOOD UNTIL SYMPTOMS SUBSIDE

Q

GASTRITIS INTERVENTIONS/ MANAGEMENT OF GASTRITIS (CHRONIC)
TAKE ACTION- WHAT WILL I DO?

A

Chronic tx is evaluating and eliminating cause –> prevent further damage

Modify diet, promote rest, reduce stress, avoid alcohol, smoking, and NSAIDs

H. pylori antibiotics, cobalamin supplements (V. B12)

DRUGS:
Antacids-
aluminium hydroxide.
magnesium carbonate.
magnesium trisilicate.
magnesium hydroxide.
calcium carbonate (tums)
sodium bicarbonate.

H2-receptor blockers (antagonists)-
-TIDINE ; [FAMOTODINE (PEPCID)]
INHIBIT DEVELOPMENT OF STRESS ULCERS
inhibits histamine (h2 receptor of acid-producing parietal cells but also stimulates acetylcholine and gastrin

Proton Pump Inhibitors (PPIs) - PRAZOLE;
decreases/slows down gastric acid of the parietal cells of stomach; PHD & GERD (PUD, H. Pylori, Dyspepsia)

Prostaglandin E1 Analog (protects Mucosa)
-Misoprostol (Cytotec)[give w/ food]
-Sucralfate (Carafate)[no food, give w/ water); may cause constipation

Q

GASTRIC ULCER

A

Pain high in epigastrium
* 1–2 hours after meals; NO NOC
* “Burning” or “gaseous”
➢ Food aggravates pain as ulcer has eroded through gastric mucosa
(drinking milk with neutralize stomach pain)

  • Prevalent in women, older adults
  • Peak incidence >50 years of age
  • Gastric ulcers are more likely than
    duodenal ulcers to result in
    HEMORRHAGE, PERFORATION, & OBSTRUCTION.
  • Hematemesis + Hemorrhage > melena (dark sticky feces w/ some blood)

Q

DUODENAL ULCER

A
  • Midepigastric region beneath xiphoid process
  • Back pain—if ulcer is located located in
    posterior aspect
  • 2–5 hours after meals/night
  • “Burning” or “cramp like”

➢Antacids alone or in combination with
an H2R blocker, as well as food, neutralize the acid to provide relief.
[CAN BE RELIEVED BY FOOD]

  • Occur at any age and in anyone:
    ↑Between ages of 35 and 45 y/o
  • Account for ~80% of all peptic ulcers *
    -Familial tendency [Genetics]
  • Melena > hematemesis

Q

Hemorrhage Assessment (4)

A

Assess for

“HOT BELLY”/ Infection –> sepsis
* Bacterial peritonitis may occur within 6–12 hours- FEVER d/t blood or rupture of an abdominal organ.

PATIENT REQUIRES IMMEDIATE SURGERY

Tx: ID CAUSE

IV FLUID
DECREASE ABDOMINAL DISTENTION

19
Q

ABDOMINAL ASSESSMENT

A

INSPECTION
AUSCULTATION
PERCUSSION
PALPATATION

20
Q

SURGICAL PROCEDURES FOR PEPTIC ULCERS (4)

A

-Billroth I (gastroDUODENostomy) stomach and duodenum are connected

-Billroth II (gastroJEJUNostomy) stomach and jejunum are connected

-Pyloroplasty enlarges the pyloric sphincter to allow for the emptying of stomach contents

-Vagotomy → works by cutting branches of the vagus nerve to stop stimulation of the parasympathetic system → digestion is part of the parasympathetic (rest and digest) → when you reduce stimulation you reduce acid production

21
Q

Nursing Interventions POST-GASTRIC SURGERY
(7 important ones)

A

*Accurate I&O measurements- malnutrition & weight loss
*V/S q 4hrs
*frequent Reposition q 2hrs
*IV therapy
*Pain management- Administer analgesics as prescribed so patient may perform pulmonary care, leg exercises, and ambulation activities
*Fowler’s position
*Maintain function of NG tube;
May require NPO with NGT connected to Low-pressure suction

-Observations for signs of infection
-Individualized nutritional care and support
-Provide interventions to reduce anxiety

22
Q

Long-term complications for GASTRIC SURGERY

A

Pernicious anemia

-d/t loss of intrinsic factor leading to malabsorption of B12
Vitamin B12 is ingested through diet Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach, necessary for the absorption of
vitamin B₁₂ later in the ileum of the small intestine

When you don’t have intrinsic factor, you won’t be able to use B12 unless given through IM injection Q month

23
Q

COMPLICATIONS of POST-GASTRIC SURGERY (5)
[BabyDaddyGaMeS][BDGMS]

A

[FIRST 2 SIMILAR TO COMPLICATIONS POST BARIATRIC]
-Bile reflux gastritis
-Dumping syndrome aka rapid gastric emptying

-Gastric retention
-Malabsorption of Vitamins and minerals
-Steatorrhea

24
Q

S/S of Dumping syndrome in GI
aka
Rapid Gastric Emptying

A

GI symptoms include (5)
-fullness
-abdominal cramps
-borborygmi (rumbling/gurgling noise)
-urge to defecate
-diarrhea

(occurs 15-30 min. after eating)

25
Q

Dumping Syndrome causes Vasomotor symptoms w/ Reactive Hypoglycemia. What are the symptoms (9)?

A

pallor (paleness), diaphoresis (sweating),
weakness, mental confusion,
dizziness (vertigo), feeling of warmth
palpitations, tachycardia, and
anxiety

Will resemble a hypoglycemic episode’s d/t rapid release insulin, when sugar is quickly absorbed by the body →leading to pallor, sweating, dizziness, confusion (vasomotor s/s)

26
Q

What is Steatorrhea ?
What is the treatment?

A

the excretion of abnormal quantities of fat with the feces leading to reduced absorption of fat by the intestine.

Tx.
-Reduce fat intake and
-administer Loperamide (Imodium) = a synthetic drug of the opiate class which inhibits peristalsis and is used to treat diarrhea.

27
Q

Patient teachings
for dietary self management to
DELAY STOMACH EMPTYING &
DUMPING SYNDROME (6)

A

-low fowler’s position after meals
-lie down for 20-30 minutes
-Eat small, frequent meal
-more DRY food items than liquids
-Low-carb diet
-Moderate protein and fat diet

Low carb → lean meats, fish, leafy green veggies, cauliflower, broccoli, nuts, beans, legumes

ALSO: (IN OTHER SLIDE)
-Avoid fluid with meals
-Avoid concentrated carbs
-Avoid high carbohydrate and sugar intake
-Avoid salt and milk
-Avoid extreme food temperatures

AVOID → milk, refined sugar, cakes, sweet drinks, dairy, alcohol

28
