What is the initial step if a PD effluent becomes cloudy?

• A. Observe for 24 hours.
• B. Suspect peritonitis, obtain effluent for Gram stain and culture, and start empiric intraperitoneal antibiotics after sample collection.
• C. Start antibiotics immediately without sampling.
• D. Switch to hemodialysis.

Answer: (B)

Cloudy PD effluent suggests peritonitis; the priority is to evaluate and treat promptly. The initial step is to collect diagnostic samples by obtaining the effluent for Gram stain and culture before starting antibiotics, then initiate empiric intraperitoneal antibiotics after the samples are taken. This order preserves the chance to identify the causative organism and its sensitivities while not delaying treatment, which is crucial to prevent complications. Intraperitoneal antibiotics are preferred in PD because they achieve higher peritoneal concentrations at the infection site. Start broad coverage that includes both common Gram-positive organisms (like Staphylococcus species) and Gram-negative bacteria, and adjust once culture results return. Do not delay sampling or switch to hemodialysis unless the patient is unstable or not responding to therapy.
