West Haven Criteria (Hepatic Encephalopathy Grading)
The West Haven Criteria grade hepatic encephalopathy from Grade 0 (minimal/none) to Grade IV (coma). Grade I: mild confusion, sleepy; Grade II: lethargy, disorientation, asterixis; Grade III: somnolent, gross disorientation; Grade IV: unrousable coma. Anaesthesia trainees use this to guide airway management, drug selection, and postoperative ICU planning in patients with liver disease.
