Child-Pugh Calculator

Liver cirrhosis severity classification and prognosis assessment

Child-Pugh Score Assessment

Total Bilirubin

Normal: <1.2 mg/dL (<20.5 μmol/L)

Serum Albumin

g/dL

Normal: 3.5-5.0 g/dL

International Normalized Ratio (INR)

Normal: 0.8-1.2

Ascites (fluid accumulation in abdomen)

Clinical assessment required

Hepatic Encephalopathy (West Haven Criteria)

Based on clinical neurological assessment

Child-Pugh Score Results

Total Score

Range: 5-15 points

Class B

Significant functional compromise

Moderate Cirrhosis

Score Breakdown:

Bilirubin:1 points

Albumin:3 points

INR:1 points

Ascites:1 points

Encephalopathy:1 points

Prognosis:

Survival Rates:

1-year: 80%

2-year: 60%

Surgical Risk:

Moderate risk - optimize condition before surgery

Clinical Outlook:

Good prognosis with appropriate treatment

Clinical Interpretations:

•Moderately decompensated liver with functional impairment
•May experience fatigue, fluid retention, or cognitive changes
•Requires closer medical supervision and treatment optimization
•Low albumin suggests reduced hepatic synthetic function

Medical Disclaimer

This Child-Pugh calculator is for educational purposes only and should not replace clinical judgment. The assessment requires professional medical evaluation of ascites and encephalopathy grades. Always consult with hepatologists and gastroenterologists for proper liver cirrhosis management and treatment decisions. Results should be interpreted in context of complete clinical assessment.

Understanding Liver Cirrhosis and Child-Pugh Classification

What is Liver Cirrhosis?

Liver cirrhosis is the pathological scarring of liver tissue where healthy hepatocytes are replaced with scar tissue, leading to progressive loss of liver function. It's not a disease itself, but a condition that develops as a result of various liver diseases.

Common Causes

•Viral Hepatitis: Hepatitis B and C infections
•Alcohol: Chronic alcohol consumption
•NASH: Non-alcoholic steatohepatitis
•Autoimmune: Autoimmune hepatitis

Child-Pugh Score Components

Laboratory Tests (3)

Bilirubin: Measures liver's ability to process waste
Albumin: Indicates liver's synthetic function
INR: Assesses blood clotting ability

Clinical Assessment (2)

Ascites: Fluid accumulation from portal hypertension
Encephalopathy: Brain dysfunction due to liver failure

Clinical Applications

Prognosis Assessment: Estimates survival and disease progression for patient counseling.

Treatment Planning: Guides therapy decisions and monitoring frequency.

Surgical Risk: Evaluates operative risk for elective procedures.

Transplant Evaluation: Helps determine timing for liver transplant referral.

Research: Standardizes patient stratification in clinical studies.
