Background/purpose: Peritoneal dialysis (PD) is a common method of renal replacement therapy for children. However, placement of PD catheters has risk, and some are never used.
Methods: We conducted a retrospective chart review of children with a PD catheter placed between 2000 and 2014. Logistic regression analyses were used to identify covariates associated with complications.
Results: We identified 175 children with PD catheters. 110 complications developed in 80 children (45.7%). Complications including unexpected return to the operating room and peritonitis increased as the length of time a catheter was in place increased. Children who weighed <12.4 kg had 3.2 times greater odds of developing a leak (95% CI 1.21-8.63, p=0.02). Twelve children never used their PD catheters, 9 with acute kidney injury (AKI) who recovered from their disease more quickly than expected. No covariate was associated with nonuse.
Conclusions: Complications with PD catheters are common and increase the longer catheters are in place. Lower weight children are at greater risk of PD catheter leak. Decreased initial volumes of dialysate in smaller children may mitigate this risk. Nonuse may be reduced if dialysis is permitted the day of placement for children with AKI.
