Effects of Different Tunnel Methods in PICC Catheterization: A Randomized Controlled Trial

This prospective randomized controlled trial compares the effectiveness and safety of one-needle and two-needle tunneling techniques for peripherally inserted central catheter (PICC) placement, aiming to identify the optimal tunneling method to reduce catheter-related complications.
