GI drug therapy

Fluid replacement H2 receptor blocker (ranindine) PPI (omezprazole)

GI nursing priorities

Focus on identifying s/s of shock :Tachycardia, weak pulse, hypotension, cool extremities, prolonged capillary refill, and apprehension, hemorrhage (1500mL hypotension & tachycardia) Urine output (best measure of vital organ profusion) Bowel sounds Palpation of abdomen

H. Pylori

H. Pylori infection often occurs by fecal-oral route. In the stomach, the bacteria can survive a long time by colonizing the gastric epithelial cells within the mucosal layer. The bacteria produce urease, which metabolizes urea-producing ammonium chloride and other damaging chemicals. Urease activates the immune response with both antibody production and the release of inflammatory cytokines. This leads to increased gastric secretion and produces tissue damage

peritonitis Dx

HX & physical CBC with differential Serum electrolytes Abdominal x-ray Paracentesis and culture CT/Ultrasound Peritoneoscopy

Diverticulitis Patient Teaching

High fiber diet High levels of physical activity increase fluid intake to 2L/day Wt. reduction Avoid increase in intraabdominal pressure (straining at stool, bending)

Hx and Physical (abdomen, rectum, pelvis) Description of pain Description of symptoms Description of sequence of symptoms Patient position: Fetal posture- peritoneal irritation Supine posture with outstretched legs- visceral pain Restlessness with seated posture- bowel obstruction, gallstones

Cholecystitis clinical manifestations

Indigestion Pain in RUQ to right shoulder and scapula Fever N/V Restlessness Diaphoresis Chills Jaundice

Pancreatitis clinical manifestations

LUQ abdominal pain that radiates to the back Flushing cyanosis Dyspnea N/V Low grade fever Hypotension Tachycardia Jaundice

Gastritis etiology

Occurs as a result of breakdown in the normal gastric mucosal barrier. This barrier normally protects the stomach tissue from the corrosive action of HCl acid and pepsin. When barrier is broken, HCl acid and pepsin can diffuse back into mucosa. The back diffusion results in edema, disruption of capillary walls with loss of plasma into the gastric lumen, and possible hemorrhage

post-op care for cholecystectomy

o monitoring for complications such as bleeding, making the patient comfortable, and preparing the patient for discharge. o A common postoperative complaint is referred pain to the shoulder because of the CO2 that is used to inflate the abdominal cavity during surgery. Placing the patient in the Sims' position (on left side with right knee flexed) helps move the gas pocket away from the diaphragm. o Encourage deep breathing along with movement and ambulation. o The pain can usually be relieved by NSAIDs or codeine. o The patient is allowed clear liquids and can walk to the bathroom to void. o If the patient has a T tube, you must maintain bile drainage and monitor T-tube function and drainage.

Colonoscopy

• Procedure: Directly visualizes entire colon up to ileocecal valve with flexible fiberoptic scope. Patient's position is changed frequently during procedure to assist with advancement of scope to cecum. • Purpose: Used to diagnose or detect inflammatory bowel disease, polyps, tumors, and diverticulosis and dilate strictures. Procedure allows for biopsy and removal of polyps without laparotomy. • Nursing Responsibilities: ♣ Before: Bowel preparation prior varies depending on HCP. For example, patient follows either a low-residue or full liquid diet the day before until bowel cleansing begins. Bowel cleansing follows a split-dose regimen. The evening before the procedure the patient drinks 2 L of oral polyethylene glycol (PEG) lavage solution. The second 2 L dose begins 4-6 hr before procedure. Explain to patient that a flexible scope will be inserted while patient in side-lying position and sedation will be given. • After: Patient may experience abdominal cramps caused by stimulation of peristalsis because the bowel is constantly inflated with air during procedure. Observe for rectal bleeding and manifestations of perforation (e.g., malaise, abdominal distention, tenesmus). Check vital signs.

EGD

• Procedure: Directly visualizes mucosal lining of esophagus, stomach, and duodenum with flexible endoscope. Test may use video imaging to visualize stomach motility. • Purpose: Detects inflammation, ulcerations, tumors, varices, or Mallory-Weiss tears. Biopsies may be taken. Varices can be treated with band ligation or sclerotherapy. • Nursing responsibilities: ♣ Before: Keep patient NPO for 8 hr. Make sure signed consent is on chart. Give preoperative medication if ordered. Explain to patient that local anesthesia may be sprayed on throat before insertion of scope and that patient will be sedated during procedure. ♣ After: Keep patient NPO until gag reflex returns. Gently tickle back of throat to determine reflex. Use warm saline gargles for relief of sore throat. Check temperature q15-30min for 1-2 hr (sudden temperature spike is sign of perforation).

Sigmoidosotmy

• Procedure: Directly visualizes rectum and sigmoid colon with lighted flexible endoscope. Sometimes a special table is used to tilt patient into knee-chest position. • Purpose: Used to detect tumors, polyps, inflammatory and infectious diseases, fissures, hemorrhoids. • Nursing Responsibilities: ♣ Before: Bowel preparation similar to colonoscopy (see Colonoscopy). Explain to patient knee-chest position (unless patient is older or very ill), need to take deep breaths during insertion of scope, and possible urge to defecate as scope is passed. Encourage patient to relax and let abdomen go limp. ♣ After: Observe for rectal bleeding after polypectomy or biopsy.
