PTRHello, what's happening?Man with moustacheHi, this woman is having plasmapheresis and she's reported some peri-oral tingling. Her ionised calcium before we started was 1.3 so I started with the standard citrate flow, but since she's gotten these symptoms I've turned it down 40% because I'm worried that she might be getting a citrate induced hypocalcaemia.PTRMmmmmmmm.[to patient]How are you feeling now?PatientA bit better I suppose.PTR[to man with moustache]So what do you think?Man with moustacheWell we're nearly finished and her symptoms have resolved somewhat. I think we might as well continue on as we are. She's due for another run tomorrow, so what I might do is leave a note for the home team asking them to give some calcium prior and start off the citrate at a lower flow rate as well.PTROk then, that sounds good. Anything else I can help you with?Man with moustacheNo, that's all thanks.PTRIt was nothing.
