CRRT question

We also recently initiated CRRT at our institution and were not inserviced very extensively prior to starting it. My biggest debate with my co-workers is about how to calculate your next hours pt fluid removal rate. Here is a hypothetical, please let me know what each of you would program in as your next removal rate for the following previous hour:
Net Goal Removal 50cc/hr
Current Pt Fluid Removal Rate 100cc/hr
This hours total Intake 350cc
Non Prisma total Output 100cc
Actual pt fluid removed for this hour 150CC
What do you program the next hour Removal Rate as? Across the board in my unit we are calculating this quite differently and it's very frustrating.

I think Dinith is right-on with the math and explanation. These volumes aren't REALLY going into the pt or coming out of them. Make sure your net is correct.

I think most institutions should require all volumes on CRRT to be documented (dialysate, replacement, effluent). These are usually high volumes, and will show mathematical errors very easily, thank God! !

Thanks everyone for your input. Just to clarify we do not record hourly set prisma volumes (i.e. replacement, dialysate, etc.). But unfortunately we also do not have a standardized formula for calculating hourly fluid removal rates. I think most of the concern is that many people do not believe you need to take into account your current removal rate to calculate the next hours rate (at the top of the hour), while others, like myself, think it has to be a factor in your calculations in order to obtain a cumulative shift targetted removal rate. Unfortunately we are still the blind leading the blind and our physicians are Trauma Surgeons not Nephrologist when this therapy is implemented which adds to the confusion (seems wiser to consult an expert in the field but that's a whole other thread!!)
