Child-Pugh score

Anesthesia risk goes up sharply at Child-Pugh B/C. Drug PK alters: avoid hepatically-cleared drugs at high dose, expect prolonged neuromuscular blockade, watch for coagulopathy + portal HTN.

Formula

Sum 5 components, each 1-3 points:

  Bilirubin:       less than 2 (1) · 2-3 (2) · greater than 3 (3) mg/dL
  Albumin:         greater than 3.5 (1) · 2.8-3.5 (2) · less than 2.8 (3) g/dL
  INR:             less than 1.7 (1) · 1.7-2.3 (2) · greater than 2.3 (3)
  Ascites:         none (1) · mild (2) · mod-severe (3)
  Encephalopathy:  none (1) · grade 1-2 (2) · grade 3-4 (3)

Class A = 5-6 (well-compensated)
Class B = 7-9 (functionally compromised)
Class C = 10-15 (decompensated)
