Ascites

Hepatic encephalopathy

Total bilirubin (milligrams per decilitre)

Standard thresholds: under 2, 2 to 3, over 3.

Serum albumin (grams per decilitre)

Standard thresholds: over 3.5, 2.8 to 3.5, under 2.8.

International normalized ratio

Standard thresholds: under 1.7, 1.7 to 2.3, over 2.3.

Notes

Child–Pugh includes clinical variables (ascites, encephalopathy). Document grading criteria explicitly for perioperative use.

Serum creatinine (milligrams per decilitre)

Lower limit 1.0; upper cap 4.0. Dialysis sets creatinine to 4.0.

Total bilirubin (milligrams per decilitre)

Lower limit 1.0 prior to logarithm.

International normalized ratio

Lower limit 1.0 prior to logarithm.

Serum sodium (millimoles per litre)

Capped between 125 and 137.

Notes

MELD-Na is commonly used in transplant allocation systems; perioperatively interpret with decompensation and trajectory.

Sex

Serum sodium (millimoles per litre)

Capped between 125 and 137.

Total bilirubin (milligrams per decilitre)

Lower limit 1.0 prior to logarithm.

International normalized ratio

Lower limit 1.0 prior to logarithm.

Serum creatinine (milligrams per decilitre)

Lower limit 1.0; upper cap 3.0.

Serum albumin (grams per decilitre)

Capped between 1.5 and 3.5.

Notes

MELD 3.0 incorporates sex and albumin and updates weights; interpret within local policy context if used for allocation.

Operational note

Uses published caps and equation; display bounded to 6 to 40 for reporting consistency.

Total bilirubin (milligrams per decilitre)

Conversion: 1 milligram per decilitre ≈ 17.1 micromoles per litre.

Serum albumin (grams per decilitre)

Conversion: grams per decilitre × 10 = grams per litre.

Notes

ALBI is objective (albumin + bilirubin). EZ-ALBI is a simplified bedside equation.

Scope

Interpret alongside portal hypertension, decompensation history, and acute-on-chronic liver failure phenotype.
