Plasmapheresis - first done at the hospital through temporary catheter, then installed a permanent one later for outpatient transfusions.
Make sure they administer calcium during procedure not before through Iv. My nurse made a mistake at first treatment, put the iv at night. I was shaking and couldnt relax all procedure, they had to give me some medicine to put me to sleep. It was a mistake on the hospitals behalf that could have caused complications. After that it was done correctly and i didnt feel anything at all.
