Cirrhosis

Pathophysiology

• Caused by destruction of liver cells, fibrosis and nodule formation restricting blood and bile flow

• Normal hepatic blood pressure is near zero.

Restriction of blood flow in liver dysfunction causes hypertension, and blood will attempt to find other pathways, bypass liver

• Results in significant impairment of liver function

• 80% destroyed before signs and symptoms

• Liver can regenerate itself if good nutrition, rest, and no alcohol

26

 Catheter

 Blood clotting problems

 Excess fluid

• Complications

▫ Puncture of lung or gallbladder

▫ Infection

▫ Bleeding

▫ Pain

33

Liver Biopsy

• Adequacy of clotting- PT/ INR, Platelets (Vit. K?)

• Type and cross match for blood

• Stop aspirin, ibuprofen, and anticoagulants 1 wk. before

• Chest x-ray

• Consent form & NPO 4 to 8 hr.

• Vital signs & Empty bladder

• Supine position, R arm above head

• Hold breath after expiration when needle inserted

• Be very still during procedure – 20 minutes

After Needle Liver Biopsy

• Pressure

• Right side

▫ minimum of 2 hrs

▫ flat 12-14 hrs

• Vital signs & check for bleeding

• NPO X 2 hr after

• Assess for peritonitis, shock, & pneumothorax

• Rt. shoulder pain common

▫ caused by irritation of the diaphragm muscle

▫ usually radiates to the shoulder a few hours or days.

• Soreness at the incision site

• Tylenol

▫ avoid aspirin or ibuprofen for the first week because they decrease blood clotting, which is crucial for healing.

• Avoid coughing, straining, lifting x 1-2 weeks

51

Sclerotherapy sclerosant solution (ethanolamine oleate or sodium tetradecyl sulphate)

Complications fever, dysphagia and chest pain, ulceration, stricture, and (rarely) perforation.

Band ligation

Fewer treatment sessions and complications than sclerotherapy.

Balloon tube tamponade

Tube is inserted through the mouth

Correct placement within the stomach is checked by auscultation while injecting air through the gastric lumen

Gastric balloon is then inflated with 200 ml of air

Gastric balloon is pulled up against the esophagogastric junction, compressing the submucosal varices

Tension is maintained by strapping a split tennis ball to the tube at the patient's mouth

Complications gastric and esophageal ulceration aspiration pneumonia

esophageal perforation.

Which of the following provides the most appropriate response?

▫ a. “The liver affected by cirrhosis is unable to produce clotting factors.”

▫ b. “The low protein diet will result in reduced clotting factors.”

▫ c. “The increased production of bile decreases clotting factors.”

▫ d. “The required medications reduce clotting factors.”

Question

• A male client is being treated for ruptured esophageal varices with a Sengstaken-Blakemore tube. His VS have been stable, and the suction port is draining scant amounts of drainage. He suddenly becomes acutely dyspneic, and oximetry reveals an

O2 sat of 74%. The nurse’s immediate action is to

▫ A. release the esophageal balloon

▫ B. release the gastric balloon

▫ C. increase the suction

▫ D. irrigate the gastric balloon

72

Question

• A newly admitted client with cirrhosis of the liver has a distended abdomen and the umbilicus is protruding. The nurse knows the pathological basis for this is

▫ B. increased size of the liver resulting in abdominal distention

▫ C. hypoalbuminemia causing fluid to leave the vascular system and enter the peritoneal cavity

▫ D. shunting of the blood to the collateral circulation in the esophagus resulting in decreased blood volume and accumulation of fluid
