Riki does "push saline" mean that is how the test the line??? make sure you are on good??? I ill make sure they push slowly!!!
If they mess up on one stick you can have dialysis using only the good one.The single needle method does mean that they have to replace all the tubing and the dialyser, so it costs 'em. I've had that twice when they failed on my venal. If they dig around for too long it can develop a clot.
Gothic — what do you mean by you only let them try twice? What's a try? If they stick the needle fully in and it misses the vein, is that a try? Or is it only a try when it penetrates the vein?
