Peritoneal Dialysis in NICU
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
Duration Of Dialysis
OUTCOME 15/25(60%) Infants survived to
come off dialysis No bleeding complications 2/15 catheters blocked - day 3 & 4

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

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

Thank you to all my colleagues @ RXH
Acute Kidney Injury:The Future is now
The past of acute kidney injury was observation,
and the present is intervention with renal replacement therapy,
but perhaps the future is the use of biomarkers to identify AKI sooner and intervene early.Bunchman TE. Oct 2009. Nephrology Times 15-16.
