I was trained with using needle guides and our team of 5 still practices this way. For those of you who also use needle guides do you have any special tips when you have punctured the vein have a great blood return and now need to insert the guide wire. Do you remove probe pulling needle away from guide on probe and gently hold the needle or do you let it "free fall" then insert your wire or do you start inserting the wire and then gently remove probe/guide from needle. I have tried it different ways and have yet to find the bests practice. There are still times I feel that my angle changes and then can't advance guidewire. It would be great to hear what others are doing.
