AKI: Treatment Modality Selection Ashita Tolwani, M.D., M.Sc. University of Alabama at Birmingham Critical Care Nephrology – Vicenza June 2015
Use of Peritoneal Dialysis in AKI: A Systematic Review AshitaTolwani • 24 studies identified • 19/24 from Asia, Africa, and South America • 13 studies with PD only • 11 studies with PD and EBP • 7 observational • 4 randomized Chionh CY et al. Clin J Am Soc Nephrol 8: 1649–1660, 2013
PD as CRRT • Alternative to Extracorporeal systems • Difficult Venous access • Small infants • “Challenged” resources • No equipment • No surgical back-up appropriate • Not about Chronic PD

Red Cross Children’s Hospital(RXH)University of Cape Town Experience • Increasing incidence in association with multi-organ failure in paediatric ICU’s • 1 200 – 1 400 admissions per year • Acute medical cases 600/yr • Cardiac cases 250/yr • Burns 50/yr • Head injuries 50/yr • Other Rest • Mortality 6% predicted 10-12% • Dialysis 3.5%
Practicalities of PD • Quick – really quick – 20 mins K+ 9! • Bed-side insertion by Paeds Nephrologist/Intensivist/Surgeons • (Surgeons as backup) • Cook/Peel Away Tenckhoff/Formal Tenckhoff • Empty Bladder • Sedation + Local Anaesthetic
Practicalities of PD • Prescription • 10-20ml/kg increase as tolerated to 50ml/kg • Dialysis fluid • 1.5%/2.5%/4.25% • Dianeal(Lactate buffered) or Bicarb based • Cycles: Fill/Dwell/Drain • 10/30-90/20mins • Manual or Cycling Home choice > 3kg • Adapted to ventilatory requirements

Peritoneal Dialysis as a Form of CRRT for Infants in a Developing Country
Specific Paeds Management IssuesVery Low Birth Weight InfantsKoralkar R et al. Ped Research 2011;69:4:354-8 • AKI reduces survival in infants <1500g • Independent risk factor • Very low glomerular filtration rate • Mild exposure – high degree of injury • High rates of infection • Nephrotoxic drugs • Premature infants <1000g • Increase SCr of 1.0mg/dL(88.5umol/l) • Doubles the odds of death
OUTCOME • 15/25(60%) Infants survived to come off dialysis • No bleeding complications • 2/15 catheters blocked - day 3 & 4 on dialysis • Nil required long term dialysis

CFPD • Performed with two bedside placed catheters: • the first conventionally placed in the midline below the umbilicus • the second one placed midway between the superior iliac crest and the umbilicus
Continuous Flow Peritoneal Dialysis Clin J Am Soc Nephrol. 2011 Feb;6(2):311-8 • CFPD useful for ARF Ronco C Perit Dial Int 27:251-3, 2007 • Especially in children • Especially if small haemodynamically infant • Developing and Developed countries • Future • Larger studies in Paeds • Higher flow volumes • Improved catheter technology

Overall recommendations: Critically ill patient with AKI • Early fluid resuscitation in acute hypovolaemia + septic shock states • Early consultation and assessment of %FO • Early initiation of CRRT + Inotropes over fluid administration to maintain BP • Appropriate expertise in management of RRT • DO what you are good at! • Do not delay • Call a friend
Take Home Message • PD is available in resource poor environment • PD is appropriate in acute setting in PICU • Not dependant on large nos and well trained staff members • Certain patient groups more suitable for PD • Practical for small infants – access + stability • Even in ‘resource rich’ hospital settings, there is a role for acute PD
