Peritoneal dialysis (PD) is a commonly used form of dialysis for pediatric patients with end-stage renal disease, particularly in children less than five years of age.
One well known complication to this mode of dialysis is PD-associated peritonitis.
Children may present with fever, abdominal pain and a cloudy dialysate.
If peritonitis is suspected, obtain sample of dialysate fluid and send for cell count, Gram’s stain and culture.
Cell count in PD-associated peritonitis is usually WBC >100 with >50% neutrophils.
Both gram-positive and gram-negative organisms are involved with PD-associated peritonitis . Keep both MRSA and Pseudomonas in mind.
In the ED, empiric therapy should cover both gram-positive and gram-negative organisms. Initiate antibiotic therapy with vancomycin and either a third-generation cephalosporin (ceftazidime) or aminoglycoside, respectively.
For PD-associated peritonitis, intraperitoneal (IP) administration of antibiotics is preferred over IV.
