What are the possible causes of Hemolysis? Appreciate your discussion.


Make the impossible POSSIBLE. I know we all can and it is the wisdom to distinguish one from the other.

You don't say why you need this information. Is it because you have a problem? Have you contacted the NKF? Other than that, common causes are poor water quality, over occlusion of the BP, excessive pressures (both +ve and -ve), insufficient rinse out of chemicals to name but a few.

A nurse called me just now telling me that a patient has suffered from Hemolysis and she has suspected it to be associated with the RO System. Am investigating the situation.

If it is the water system I would check the chlorine levels, although if it is a central water plant it would be unusual for this to affect only one patient.

Hi Roger,
As techman has highlighted the presence of Chrlorine Dioxide in the water can cause hemolysis. Where is your water from this treatment taken being supplied from? Is it possible that the Estates Dept have added Chlorine Dioxide to the supply and not advised the Renal Unit?

What does your suppy system consist of, Charcoal Filters, Central RO?

Can the supply be tested using a DPD kit? (Between Carbon Filters) This wll detect Chlorine and Chloramine.

Has this occured with just the one patient, is it possible the machone has not been rinsed properlly post bleaching?

Our RO is a standalone Type.

Apparently the RO has not been working well. We have since sideline the RO and is awaiting the replacement of the membrane.

Thanks to all who have responded.
