today we had a pt who is a hardstick, and the nurse just used ultrasound and microintroducer kit to do the PIV. She first idetified the vein with ultrasound and set up the sterile field just like start a PICC line, sheÂ used cholraprp to prep the arm, and then she used OR towels to circle the area, and then she used lidocaine to numb the pt and used the IR needle to get the vein puncture and then she inserted the dialator, but to my surprise, she just kept the dialator in pt's vein and then sent pt to CT scan. So basically she used dialator as PIV for the pt. Pt had CT scan and IV contrast went in no problem. But I was wondering can she do that. because technically, it is a midline placement and I think we need a doctor's order for that, plus microintroducer kit is expensive. the charge to the pt is different than normal PIV. Can anybody share your thoughts about this?????
