Effects of Different Tunnel Methods in PICC Catheterization

18. maj 2026 opdateret af: Zeyin Hu, Sun Yat-sen University

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.

Intervention / Behandling
Aktiv komparator: cancer patients who undergo PICC placement using 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 sheath inserted over guide wire, catheter trimmed to length, advanced through sheath after guide wire removal;
  7. Vascular sheath peeled off, catheter adjusted to proper position;
  8. Catheter tip position confirmed;
  9. Puncture site closed with suture-free tape, both sites covered with sterile dressings, catheter secured.

Eksperimentel: cancer patients who undergo PICC placement using one-needle tunnel technique

Ultrasound guidance is used for vascular puncture and assisted subcutaneous tunnel creation:

  1. Local anesthesia is administered at the puncture site,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, and the catheter is secured.
