Abstract

Abstract Background Dialysis is lifesaving for acute kidney injury (AKI), but access is poor in less resourced settings. A “peritoneal dialysis (PD) first” policy for paediatric AKI is more feasible than haemodialysis in low-resource settings. Methods Retrospective review of modalities and outcomes of children dialysed acutely at Red Cross War Memorial Children’s Hospital between 1998 and 2020. Results Of the 593 children with AKI who received dialysis, 463 (78.1%) received PD first. Median age was 9.0 (range 0.03–219.3; IQR 13.0–69.6) months; 57.6% were < 1 year old. Weights ranged from 0.9 to 2.0 kg (median 7.0 kg, IQR 3.0–16.0 kg); 38.6% were < 5 kg. PD was used more in younger children compared to extracorporeal dialysis (ECD), with median ages 6.4 (IQR 0.9–30.4) vs. 73.9 (IQR 17.5–113.9) months, respectively (p = 0.001). PD was performed with Seldinger soft catheters (n = 480/578, 83%), predominantly inserted by paediatricians at the bedside (n = 412/490, 84.1%). Complications occurred in 127/560 (22.7%) children receiving PD. Overall, 314/542 (57.8%) children survived. Survival was significantly lower in neonates (< 1 month old, 47.5%) and infants (1–12 months old, 49.2%) compared with older children (> 1 year old, 70.4%, p < 0.0001). Survival was superior in the ECD (75.4%) than in the PD group (55.6%, p = 0.002). Conclusions “PD First for Paediatric AKI” is a valuable therapeutic approach for children with AKI. It is feasible in low-resourced settings where bedside PD catheter insertion can be safely taught and is an acceptable dialysis modality, especially in settings where children with AKI would otherwise not survive.
