Schindl et al reported a score for grading the severity of hepatic dysfunction following a major hepatic resection based on a number of clinical and laboratory findings. The authors are from the Royal Infirmary in Edinburgh.
Patient selection: major hepatic resection
Parameters:
(1) grade of hepatic encephalopathy
(2) serum lactate in mmol/L
(3) serum total bilirubin in µmol/L
(4) prothrombin time in seconds above normal (prothrombin time minus “normal”)

where:
• The “normal” value for the prothrombin time could be pegged to the upper limit of the normal reference range or to the mean value.
total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 8
• The higher the score the more severe the hepatic dysfunction.
