Hello, thanks for the answer. Let me clarify. In my environment we prepare the replacement solution in this way, we have 20% albumin for 50 ml, for example, if we perform a plasmapheresis total volume of 2800 ml; We took 14 jars to take it to 5% and the rest with a crystalloid solution, in my practice I use saline solution, others use even 1.5% dianeal solutions, but I have never read to bring the total volume with ringer lactate. This last one is my doubt, Thanks in advance any help, and if you can explain to me in your practice how they make the preparation of the replacement solution.
