Severe (Grade III) acute cholangitis is a critical presentation defined by failure of one or more organ systems. This level of severity warrants urgent escalation beyond standard cholangitis management.

Clinical Scenario

Grade III acute cholangitis is diagnosed when onset of dysfunction is present in at least one of the following organs or systems:

Cardiovascular — hypotension requiring dopamine ≥5 µg/kg/min or any dose of norepinephrine
Neurological — disturbance of consciousness
Respiratory — PaO₂/FiO₂ ratio <300
Renal — oliguria, serum creatinine >2.0 mg/dl
Hepatic — PT-INR >1.5
Hematological — platelet count <100,000/mm³

Management Approach

Management of Grade III acute cholangitis involves urgent biliary drainage, organ support, and antibiotic therapy — the specific combination, sequence, and selection depend on the clinical picture.

The complete structured regimen, including agent selection, timing, and decision pathway, is available in the full protocol.
