Do you use Dialysis en extrem preterm less than 500 gr.?  In context of anuria  (but not after cardiac surgery).

Is There  an age limit, or a weight limit?. 

 

I remember a Former 25+2 weeks premie without severe complications who suffered (from insensible water loss because of cutan barrier disturbance) prerenal acute kidney insuffiency und later severe damage at age of 2 and a half weeks.  1150 g. The neonatal/ nephrological Team of an great south german University Hospital tried peritoneal dialysis (with Lot of improvising work on catheters, solutions, leaks, infection) and have succeeed in the end. Respect.

So I think there are two issues here:

1) Why do you think the child is anuric and what mode of kidney support therapy are you proposing to address the issue? (as an ancillary - what is the end point?)

2) Given the size, is your proposed plan even technically feasible?

Assuming you mean PD and not CRRT/iHD, https://bmcnephrol.biomedcentral.com/articles/10.1186/s12882-020-02092-1 provides some experience and suggests that it may at least be technically feasible. Beyond that, I think you'd need to provide more details on the actual circumstances that led you to want to pursue PD for anyone to sensibly answer your question.
