Podcast 528: Decompensated Liver Failure

Contributor: Michael Hunt, MD

Educational Pearls:

• Cirrhosis is the end stage of chronic structural damage to the liver. This is most commonly due to alcohol but other causes viral hepatitis and hepatotoxic drugs
• Cirrhotic patients are very prone to GI bleeding and infections, partially due to the role the liver plays in producing immune and clotting factors
• These patients can easily become "sick". Use the shock index (heart rate / systolic blood pressure) as a rapid assessment of hemodynamic status. >0.7 is worrisome, >1 should prompt resuscitation.
• Because cirrhotic patients are immunocompromised, do not rely on the presence of fever and peritonitis to diagnose spontaneous bacterial peritonitis (SBP), and have a low threshold to perform a diagnostic paracentesis
• Polymorphonuclear (PMN) count > 250 in the ascitic fluid suggests SBP
• With GI bleeding in cirrhotics, antibiotics have a mortality benefit, while PPIs and octreotide have limited benefit
