    Higher up in colon and small intestine, mixed with stool
  • Coffee ground blood
    Esophagus, stomach, and duodenum

    Acute, bright red hematemesis or large amount of black tarry stool, Rapid pulse, hypotension, hypovolemia and shock
  • Subacute bleeding
    Intermittent/alternate melena or coffee ground emesis, Weakness, dizziness
  • Chronic Bleeding
    Intermittent appearance of blood, Increased weakness, paleness or SOB, Occult blood
  • Diagnostic tests

    • History
    • CBC
    • Endoscopy and MRI or CT
    • Stool test- for occult blood
  • History
    Change in bowel pattern, Presence of pain or tenderness, Recent intake of food and what kind(red beef), Alcohol consumption and medications taken (aspirin or steroids, NSAIDS)
  • CBC
    Low hemoglobin, high hematocrit, low platelet, High PT( 10-12 sec ) and aPTT( 30-45sec); NV
  • Endoscopy and MRI or CT
    Identifies the source and cause of bleeding
  • Emergency intervention
    1. Patient remains on NPO
    2. IV lines and oxygen therapy
    3. Administer vasopressin and blood replacement
    4. Intra arterial vasopressin- to slow or stop bleeding from diverticulum
    5. Surgical if indicated
    6. Nasogastric tube Intubation
  • Nasogastric tube Intubation
    1. An NG tube should be in place for most patients with acute or upper GI bleeding
    2. 2-3 L of tap water lavage and if the aspirate continues to be bloody, this indicate that the patient is in active bleeding that requires emergent intervention
  • Nursing interventions
    1. Attaining Normal Fluid Volume
    2. Attaining Balance Nutritional Status
  • Attaining Normal Fluid Volume
    Maintain NG tube and NPO status to rest GI tract and evaluate bleeding, Monitor I and O to evaluate fluid status and hydration, Monitor VS, Administer IV fluids, Assess signs of shock such as hypotension, tachycardia, tachypnea (increase RR), decrease urine output, change in mental status
  • Attaining Balance Nutritional Status
    Weigh daily to monitor caloric status', TPN, to promote hydration and nutrition while on NPO restriction, Begin liquids if patient is no longer on NPO, then DAT. DAT should be high in calorie, high CHON. Frequent small feedings if indicated
  • Patient education
    Instruct the patient to report signs of GI bleeding such as melena, emesis that is bright red or coffee ground color, rectal bleeding, weakness, fatigue and SOB
  • Evaluation: Fluid volume is maintained, hypovolemic shock is prevented, Patient verbalized no signs of bleeding, Nutritional and body weight status is maintained
  • Complications
    • Hemorrhage
    • Shock
    • Death
  • Gastritis
    Inflammation of the gastric or stomach mucosa
  • Types of gastritis
    • Acute
    • Chronic
  • Acute gastritis
    Lasting several hours to few days
  • Causes of acute gastritis
    • Severe form caused by ingestion of strong acid or alkali
    • Acute illnesses or major traumatic injuries (Burns, severe infection, hepatic,kidney or respiratory failure and major surgery)
  • Classification of acute gastritis
    • Erosive Acute Gastritis
    • Non-Erosive Acute Gastritis
  • Erosive Acute Gastritis
    Most often caused by local irritants such as aspirin and other NSAIDS (Naproxen, Voltaren, Ibuprofen), alcohol consumption and gastric radiation therapy
  • Non-Erosive Acute Gastritis
    Most often caused by an infection with Helicobacter Pylori (H. Pylori)
  • Chronic gastritis
    Results from repeated exposure to irritating agents or recurrent episodes of acute gastritis
  • Causes of chronic gastritis
    • H. Pylori infection
    • Chemical gastric injury (Gastropathy)- long term use of NSAIDS and aspirin
    • Autoimmune disease- Hashimoto thyroiditis, Addison's disease, Grave's disease
  • Pathophysiology of gastritis
    Disruption of the mucosal barrier that normally protects the stomach from digestive juices (Hcl and pepsin) are irritating agents (Aspirin, NSAID and H. Pylori) comes in contact with the gastric mucosa that resulted to inflammation. In acute gastritis, the inflammation is usually transient and self-limiting in nature. In chronic gastritis, persistent and repeated insults lead to chronic inflammation that leads to atrophy or thinning of the gastric tissue.
  • Clinical manifestations of acute gastritis
    • Hiccups
    • Anorexia
    • Epigastric pain (rapid onset
    • Dyspepsia (Indigestion)
    • Nausea and vomiting
    • Melena (black, tarry stools,) hematemesis (blood in vomitus), hematochezia (bright red, bloody stools)
    • Possible sign of shock
