1 Focus on Cirrhosis of the Liver
(Relates to Chapter 44, “Nursing Management: Liver, Pancreas, and Biliary Tract Problems” in the textbook)

2 Cirrhosis Description
A chronic progressive disease of the liver Extensive parenchymal cell degeneration Destruction of parenchymal cells

3 Cirrhosis Fig. 44-4

4 Cirrhosis Description
Liver cells attempt to regenerate Regenerative process is disorganized Abnormal blood vessel and bile duct formation New fibrous connective tissue distorts liver’s normal structure, impedes blood flow Poor cellular nutrition and hypoxia results

5 Cirrhosis Description
Insidious, prolonged course Ninth leading cause of death in United States Fourth leading cause of death in persons ages 35 to 54 Twice as common in men

6 Cirrhosis Etiology and Pathophysiology
Four types of cirrhosis 1. Alcoholic cirrhosis Also called portal or nutritional Usually associated with alcohol abuse First change from excessive alcohol intake is fat accumulation in liver cells With continued abuse, scar formation occurs

7 Cirrhosis Etiology and Pathophysiology
Four types (cont’d) 2. Postnecrotic cirrhosis Complication of viral, toxic, or idiopathic hepatitis Bands of scar tissue form

8 Cirrhosis Etiology and Pathophysiology
Four types (cont’d) 3. Biliary cirrhosis Associated with chronic biliary obstruction Diffuse fibrosis of liver with jaundice 4. Cardiac cirrhosis From long-standing severe right-sided heart failure

9 Cirrhosis Etiology and Pathophysiology
Cause may not be determined in all patients Most common cause: Excessive alcohol ingestion Environmental factors may lead to development Some may be predisposed, regardless of alcohol intake or diet

10 Manifestations of Liver Cirrhosis
Fig. 44-6

11 Cirrhosis Clinical Manifestations
Early manifestations Onset usually insidious GI disturbances: Anorexia Dyspepsia Flatulence Nausea/vomiting Change in bowel habits

12 Cirrhosis Clinical Manifestations
Early manifestations (cont’d) Abdominal pain Fever Lassitude Weight loss Enlarged liver or spleen

13 Cirrhosis Clinical Manifestations
Late manifestations Two causative mechanisms Hepatocellular failure Portal hypertension

14 Cirrhosis Clinical Manifestations
Late manifestations (cont’d) Jaundice Decreased ability to conjugate and excrete bilirubin by liver cells Functional derangement of liver cells Compression of bile ducts by overgrowth of connective tissue

15 Cirrhosis Clinical Manifestations
Jaundice (cont’d) Minimal or severe depending on liver damage Late stages of cirrhosis Patient will usually be jaundiced Pruritus from accumulation of bile salts

16 Cirrhosis Clinical Manifestations
Skin lesions Due to increase in circulating estrogen from liver’s inability to metabolize steroid hormones

17 Cirrhosis Clinical Manifestations
Skin lesions (cont’d) Spider angiomas Small dilated blood vessels with bright red center and spiderlike branches Nose, cheeks, upper trunk, neck, shoulders Palmar erythema Red area on palms of bands that blanches with pressure

18 Cirrhosis Clinical Manifestations
Endocrine disorders Steroid hormones of the adrenal cortex (aldosterone), testes, and ovaries are metabolized and inactivated by the normal liver Damaged liver is unable to metabolize these hormones and various manifestations occur

19 Cirrhosis Clinical Manifestations
Endocrine disturbances Alteration in hair distribution due to ↑ estrogen Hyperaldosterism Sodium retention/potassium loss

20 Cirrhosis Clinical Manifestations
Hematologic disorders Splenomegaly From backup of blood from portal vein Bleeding tendencies Decreased production of hepatic clotting factors

21 Cirrhosis Clinical Manifestations
Peripheral neuropathy Dietary deficiencies of thiamine, folic acid, and vitamin B12

22 Cirrhosis Complications
Portal hypertension Esophageal and gastric varices Peripheral edema and ascites Hepatic encephalopathy Hepatorenal syndrome

23 Cirrhosis Complications
Portal hypertension Characterized by Increased venous pressure in portal circulation Splenomegaly Ascites Large collateral veins Esophageal varices Systemic hypertension

24 Cirrhosis Complications
Portal hypertension (cont’d) Primary mechanism is the increased resistance to blood flow through the liver

25 Cirrhosis Complications
Portal hypertension (cont’d) Esophageal varices Complex of tortuous veins at lower end of esophagus Develop in areas where collateral and systemic circulations communicate

26 Cirrhosis Complications
Esophageal varices (cont’d) Contain little elastic tissue and are fragile Bleeding esophageal varices Most life-threatening complication of cirrhosis 80% of variceal hemorrhages

27 Cirrhosis Complications
Portal hypertension (cont’d) Gastric varices Located in upper portion of stomach 20% of variceal hemorrhages

28 Cirrhosis Complications
Portal hypertension (cont’d) Internal hemorrhoids Occur because of the dilation of the mesenteric veins and rectal veins Caput medusae Ring of varices around the umbilicus

29

30 Cirrhosis Complications
Peripheral edema and ascites Edema ↓ Colloidal oncotic pressure from impaired liver synthesis of albumin ↑ Portacaval pressure from portal hypertension Occurs as ankle/presacral edema

31 Cirrhosis Complications
Peripheral edema and ascites (cont’d) Ascites Accumulation of serous fluid in peritoneal or abdominal cavity Abdominal distention with weight gain Common manifestation of cirrhosis

32 Ascites and Gynecomastia
Fig. 44-8

33 Cirrhosis Complications
Ascites (cont’d) Factors involved in the pathogenesis ↓ Serum colloidal oncotic pressure ↑ Levels of aldosterone Portal hypertension ↑ Flow hepatic lymph Impaired water excretion

34 Development of Ascites
Fig. 44-7

35 Cirrhosis Complications
Hepatic encephalopathy Neuropsychiatric manifestation Terminal complication in liver disease

36 Cirrhosis Complications
Hepatic encephalopathy (cont’d) Etiologic factors Disorder of protein metabolism and excretion Liver unable to convert ammonia to urea or blood shunted pass liver through so ammonia stays in systemic circulation Ammonia crosses blood-brain barrier and causes neurologic toxic manifestations

37 Cirrhosis Complications
Hepatic encephalopathy (cont’d) Etiologic factors (cont’d) Altered astrocyte function Regulate blood-brain barrier and detoxification of ammonia

38 Cirrhosis Complications
Hepatic encephalopathy (cont’d) Clinical manifestations Changes in neurologic and mental responsiveness Ranging from sleep disturbance to lethargy to deep coma

39 Cirrhosis Complications
Hepatic encephalopathy (cont’d) Grading system used to classify stages Stages 0–4 4 is most advanced Asterixis Characteristic symptom Flapping tremors involving arms and hands

40 Cirrhosis Complications
Hepatic encephalopathy (cont’d) Fetor hepaticus Musty, sweet odor on patient’s breath Accumulation of digestive by-products liver is unable to degrade

41 Cirrhosis Complications
Hepatorenal syndrome Serious complication of cirrhosis Functional renal failure with Azotemia Oliguria Intractable ascites

42 Cirrhosis Complications
Hepatorenal syndrome (cont’d) No structural abnormality of kidney Splanchnic and systemic vasodilation and ↓ arterial blood volume Renal vasoconstriction occurs with renal failure

43 Cirrhosis Diagnostic Studies
History/physical examination Laboratory tests Liver function tests Serum electrolytes CBC

44 Cirrhosis Diagnostic Studies
Laboratory tests (cont’d) Prothrombin time Serum albumin Stool for occult blood Analysis of ascitic fluid

45 Cirrhosis Diagnostic Studies
Esophagogastroduodenoscopy Liver biopsy Barium swallow Liver scan Liver ultrasound Angiography

46 Cirrhosis Collaborative Care
Rest Administration of B-complex vitamins Avoidance of alcohol, aspirin, acetaminophen, and NSAIDs Management of ascites

47 Cirrhosis Collaborative Care
Prevention and management of esophageal variceal bleeding Management of encephalopathy

48 Cirrhosis Collaborative Care
Ascites High-carbohydrate, low-Na+ diet (2 g/day) Diuretics Paracentesis Removes fluid from abdominal cavity Temporary measure

49 Cirrhosis Collaborative Care
Ascites (cont’d) Peritoneovenous shunt Continuous reinfusion of ascitic fluid from the abdomen to the vena cava Not first-line therapy Complications—thrombosis, infection, fluid overload, DIC

50 Peritoneovenous Shunt
Fig. 44-9

51 Cirrhosis Collaborative Care
Esophageal and gastric varices Goal: avoid bleeding/hemorrhage Avoid alcohol, aspirin, and irritating foods Respiratory infection promptly treated

52 Cirrhosis Collaborative Care
If bleeding occurs, stabilize patient, manage the airway, IV therapy IV vasopressin to control bleeding Nitroglycerin to decrease side effects of vasopressin

53 Cirrhosis Collaborative Care
Endoscopic sclerotherapy Treatment for acute/chronic bleeding varices Agent (morrhuate [Scleromate]) Thromboses and obliterates distended veins

54 Cirrhosis Collaborative Care
Endoscopic ligation Banding of varices Fewer complications than sclerotherapy Balloon tamponade Controls hemorrhage by compression of varices Uses Sengstaken-Blakemore tube

55 Sengstaken-Blakemore Tube
Fig

56 Cirrhosis Collaborative Care
Supportive measures for acute bleed Fresh frozen plasma Packed RBCs Vitamin K Histamine receptor blockers Proton pump inhibitors Neomycin

57 Cirrhosis Collaborative Care
Long-term management Propranolol (Inderal) to prevent recurrent GI bleed High incidence of recurrent bleed with high mortality risk with each repeat

58 Cirrhosis Collaborative Care
Shunting procedures Used more after second major bleeding episode Surgical versus nonsurgical

59 Cirrhosis Collaborative Care
Nonsurgical procedure Transjugular intrahepatic portosystemic shunt (TIPS) Tract (shunt) between systemic and portal venous system Used to redirect portal blood flow Decreases portal venous pressure and decompresses varices

60 Total Portal Division After TIPS
Fig

61 Cirrhosis Collaborative Care
Surgical procedures Used more in emergency situations Portacaval shunt Decreases bleeding episodes Does not prolong life; patient dies of hepatic encephalopathy

62 Cirrhosis Collaborative Care
Surgical procedures (cont’d) Distal splenorenal shunt (Warren shunt) Leaves portal venous flow intact ↓ Incidence of hepatic encephalopathy With time blood flow to liver ↓

63 Portosystemic Shunts Fig

64 Cirrhosis Collaborative Care
Hepatic encephalopathy Goal: Decrease ammonia formation Sterilization of GI tract with antibiotics (e.g., neomycin) Lactulose (Cephulac) traps NH3 in gut Cathartics/enemas

65 Cirrhosis Collaborative Care
Drug therapy No specific drug therapy Drugs are used to treat symptoms and complications of advanced liver disease
