Podcast 676: Spontaneous Bacterial Peritonitis

Contributor: Sam Killian, MD

Educational Pearls:

• Patients with cirrhosis and ascites are frequently evaluated for spontaneous bacterial peritonitis, an infection of the ascites fluid that is not from a surgically treated source
• Fever, abdominal pain, and altered mental status should all raise clinical suspicion in a patient with ascites
• Fluid from paracentesis may show increased WBCS (polys and neutrophils), high LDH, high amylase, and decreased glucose
• Outcomes are very poor in these patients with 30-40% of these patients continue to renal failure with 60-80% in-hospital mortality
• Typically treat with a third generation cephalosporin or ampicillin+gentamicin
