How PD peritonitis is managed after obtaining effluent culture?

• A. Wait for culture results before starting antibiotics.
• B. Initiate empiric intraperitoneal antibiotics promptly, send effluent for culture, and tailor antibiotics to culture results, typically continuing treatment for about 14 days if uncomplicated.
• C. Use oral antibiotics only.
• D. Stop PD and convert to hemodialysis.

Answer: (B)

Initiate empiric intraperitoneal antibiotics right away after obtaining the effluent culture, rather than waiting for results. PD peritonitis is treated as a time-sensitive infection, and delivering antibiotics directly into the peritoneal cavity achieves high local drug levels quickly, which improves outcomes. At the same time, send the effluent for culture so you can identify the organism and its sensitivities and tailor therapy accordingly. If the infection is uncomplicated, a typical course is about 14 days, with longer or different regimens if the organism is resistant, if there is poor response, or if complications arise. Oral antibiotics aren’t sufficient because they don’t reliably achieve adequate peritoneal concentrations, and stopping PD to convert to hemodialysis is reserved for cases where the infection cannot be controlled or catheter salvage is not possible.
