Official title
Effects of Different Tunnel Methods in PICC Catheterization: A Randomized Controlled Trial
Overview
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.
Interventions
- Other One-needle tunnel technique
1. Local anesthesia is administered at the puncture site,Ultrasound guidance is used for vascular puncture and assisted subcutaneous tunnel creation,the puncture needle travels 4 cm through the subcutaneous tissue before entering the blood vessel; 2. The guide wire is inserted along the puncture needle; 3. skin dilation; 4. The vascular sheath is advanced into the blood vessel via the guide wire, and the catheter is inserted through the vascular sheath; 5. The catheter tip position is confirmed, - Other two-needle tunnel technique
Two-needle tunnel PICC procedure: 1. Local anesthesia at puncture and catheter exit sites; 2. Ultrasound-guided vascular puncture at puncture site, guide wire inserted via puncture needle; 3. Skin dilation at both puncture and exit sites; 4. 4cm saline tunnel created with 0.9% NaCl: 10mL syringe advanced along tunnel path while injecting solution; 5. Subcutaneous tunnel formed from exit site to puncture site with tunneling tool, catheter pulled through tunnel to puncture site; 6. Vascular sheat
Primary outcome measures
- overall PICC-related complications after catheter placement [Time frame: 4 weeks after PICC placement]
Secondary outcome measures (4)
- first-puncture success rate of PICC catheterization [Time frame: day 1 during PICC catheterization]
- pain score [Time frame: Day 1 during PICC placement]
- Bleeding during PICC placement [Time frame: Day 1 during PICC placement]
- unplanned catheter removal rate of PICC [Time frame: 4 weeks after PICC placement]
