Cirrhosis is a late stage of hepatic fibrosis where normal liver tissue is slowly replaced by scar tissue. This process disrupts the entire structure of the liver, blocking the normal flow of blood through the organ. As healthy cells die and nodules of regenerating tissue form, the liver gradually loses its ability to process nutrients, filter toxins, and manufacture vital proteins. While the damage is largely irreversible, early recognition and lifestyle changes can slow down further deterioration and preserve remaining liver function.
The underlying mechanism of cirrhosis involves chronic injury to hepatocytes. When liver cells are repeatedly damaged, inflammatory cells release cytokines that activate hepatic stellate cells. Once awakened, these cells transform into myofibroblasts and begin producing dense collagen and extracellular matrix proteins. Over years, this excessive extracellular matrix accumulation creates fibrous septa. This structural distortion compresses the vascular sinusoids and hepatic veins, severely impairing metabolic functions and synthesis of clotting factors.
In Nigerian clinical practice, the etiology of cirrhosis differs somewhat from Western countries.
Patients with cirrhosis present with a wide array of signs depending on how advanced the disease has become. Early stages may display only vague fatigue and poor appetite. As liver function declines and portal pressure rises, classic physical signs emerge.
| Finding | Underlying Cause | Description |
|---|---|---|
| Jaundice | Impaired bilirubin metabolism | Yellow discoloration of sclera and skin |
| Ascites | Portal hypertension & hypoalbuminemia | Accumulation of fluid in the peritoneal cavity |
| Spider Angiomas | Altered estrogen metabolism | Tiny dilated blood vessels on the upper chest and face |
| Palmar Erythema | Hyperdynamic circulation | Redness over the palms of the hands |
| Splenomegaly | Backpressure in the portal system | Enlarged spleen felt in the left upper quadrant |
Diagnosing cirrhosis requires combining clinical history, laboratory blood panels, and imaging studies. Liver function tests (LFTs) often show elevated aminotransferases (AST and ALT), though these enzymes can drop in end-stage disease when few hepatocytes remain. Serum albumin levels fall because the damaged liver synthesizes fewer proteins, leading to low oncotic pressure. Coagulation profiles reveal prolonged prothrombin times due to a lack of clotting factors. Abdominal ultrasound is the primary imaging choice to visualize a nodular liver surface, splenomegaly, and ascites.
Midwifery and nursing care for patients with cirrhosis focuses on monitoring fluid balance, preventing complications, and supporting nutrition. Nurses must track daily weights, measure abdominal girth, and record strict intake and output to evaluate fluid retention. Providing frequent, small, high-carbohydrate and moderate-protein meals helps combat malnutrition without triggering nitrogen overload. Skin care is critical because edema and jaundice make fragile skin prone to pressure ulcers and severe itching.
Complications can escalate rapidly in cirrhosis, demanding prompt intervention. Ascites is managed through sodium restriction and diuretic therapy such as spironolactone, sometimes requiring therapeutic paracentesis. Hepatic encephalopathy occurs when nitrogenous waste products like ammonia bypass the liver and affect brain function. Nurses monitor for early signs of confusion, personality changes, and the characteristic flapping hand tremor known as asterixis. Lactulose is administered to trap ammonia in the bowel and promote its excretion.
Empowering patients and their families is essential for long-term survival and quality of life. Education must emphasize absolute abstinence from alcohol and avoidance of unprescribed herbal remedies or traditional concoctions that can be hepatotoxic. Patients should learn to read food labels to strictly adhere to a low-sodium diet. They also need clear instructions on recognizing danger signs like vomiting blood, black tarry stools, or worsening confusion, which require immediate hospital readmission.
