Peritonitis

Peritonitis

The peritoneal fluid (PDF) on the left is clear. You can see through the bag. The PDF on the right is turbid. The most common cause of turbid PDF is peritonitis. Patients usually present with a triad of fever, abdominal pain and turbid PDF. It is important not to miss peritonitis secondary to a surgical abdomen (e.g. appendicitis, incarcerated hernia). One should look carefully for any localized tenderness in the abdomen and the inguinal regions. The exit site and tunnel tract of the catheter should also be examined. Peritonitis is defined by PDF white cell count more than 100/mm3, with at least 50% polymorphonuclear neutrophilic cells.
