Use of ultrasound guidance for peripheral intravenous placement in difficult-to-access patients: advancing practice with evidence.

Placement of peripheral intravenous (PIV) lines in difficult-to-access patients can be daunting. Multiple unsuccessful peripheral sticks, numerous PIV restarts, and potentially excess use of peripherally inserted central catheters can result. The goals of this project were to decrease the number of peripherally inserted central catheter referrals and lower the number of PIV restarts by having clinical nurses employ ultrasound guidance when initiating deep PIVs. After 10 months of nurses using the ultrasound as needed to insert a PIV line, the number of total peripherally inserted central catheter referrals decreased by 20%.
