概要	The West Haven Criteria are the standard for grading hepatic encephalopathy (HE) severity, ranging from subclinical (Grade 0) to deep coma (Grade 4). Developed by Trey and Davidson in the 1960s and refined by the West Haven group, these criteria integrate mental status changes (confusion, asterixis, disorientation) and consciousness level to stage HE. The West Haven grade is a strong predictor of short-term prognosis in cirrhosis and guides urgency of intervention (lactulose, rifaxomicin, mannitol, intubation).	The Child-Pugh Score (originally Child-Turcotte, modified by Pugh in 1973) is a clinical scoring system that stratifies the severity of liver cirrhosis and predicts surgical mortality and prognosis. The score integrates five readily available clinical and laboratory parameters: bilirubin, albumin, prothrombin time (INR), ascites, and hepatic encephalopathy. With a total range of 5–15 points, the Child-Pugh Score is stratified into Class A (mild, 5–6 points), Class B (moderate, 7–9 points), and Class C (severe, 10–15 points), each with distinct mortality predictions.
