Effects of Different PICC Catheterization Methods: A Multicenter Randomized Controlled Trial

2026년 8월 25일 업데이트: Zeyin Hu, Sun Yat-sen University
This study aims to compare the clinical effectiveness of three PICC (Peripherally Inserted Central Catheter) insertion methods: conventional non-tunneled PICC, one-needle tunneled PICC, and two-needle tunneled PICC. This is a multicenter randomized controlled trial involving 11 hospitals in China, with a total of 801 patients scheduled to undergo PICC insertion for the first time. Patients will be randomly assigned in a 1:1:1 ratio to the three groups. The primary outcome is the incidence of post-insertion complications (including oozing, infection, thrombosis, catheter dislodgement, etc.) within 90 days. Secondary outcomes include one-time puncture success rate, pain level (NRS), bleeding volume, catheterization time, and unplanned catheter removal rate. The results will provide evidence for selecting the optimal PICC insertion method in clinical practice.

상세 설명

This study adopts a prospective, multicenter, three-arm, parallel-group randomized controlled design. A total of 801 patients will be recruited from 11 hospitals and randomly assigned in a 1:1:1 ratio to the three groups. The control group receives conventional non-tunneled PICC insertion. Experimental group 1 receives one-needle tunneled insertion (the needle travels subcutaneously for 4 cm before entering the vessel). Experimental group 2 receives two-needle tunneled insertion (with a 4 cm subcutaneous tunnel created using a tunneling tool). All insertions are performed by certified PICC nurses with over 5 years of experience who have received standardized training. The primary outcome is the overall incidence of catheter-related complications within 90 days post-insertion. Secondary outcomes include one-time puncture success rate, NRS pain score, intraoperative bleeding volume, catheterization time, and unplanned catheter removal rate. Outcome assessors and data analysts are blinded to group allocation. The study has been approved by the Ethics Committee of Sun Yat-sen University Cancer Center (Approval No. B2026-467-01, dated August 10, 2026).

활성 비교기: Conventional Non-Tunneled PICC catheterization
Patients receive conventional non-tunneled PICC insertion. The procedure involves ultrasound-guided vein puncture, guidewire insertion, local anesthesia and skin dilation, followed by sheath and catheter advancement. The catheter exit site is at the puncture site.
절차: Conventional Non-Tunneled PICC catheterization
Ultrasound-guided vein puncture, followed by guidewire insertion, local anesthesia, skin dilation, sheath advancement, and catheter delivery. The catheter exit site is at the puncture site with no subcutaneous tunnel created.
실험적: One-Needle Tunneled PICC catheterization
Patients receive one-needle tunneled PICC insertion. The puncture needle travels subcutaneously for 4 cm before entering the vessel, creating a subcutaneous tunnel. The skin puncture and catheter exit sites are the same. This technique requires only one needle pass for both tunneling and vessel puncture.
절차: One-Needle Tunneled PICC catheterization
The puncture needle travels subcutaneously for 4 cm before entering the vessel, creating a subcutaneous tunnel with a single needle pass. The puncture site and catheter exit site are the same. This technique combines tunneling and vessel puncture in one step.
실험적: Two-Needle Tunneled PICC catheterization
Patients receive two-needle tunneled PICC insertion. Ultrasound-guided vein puncture is performed first, followed by creation of a 4 cm subcutaneous tunnel using a tunneling tool. The puncture site and catheter exit site are separate, with a subcutaneous tunnel connecting them.
절차: Two-Needle Tunneled PICC catheterization
A two-step procedure: first, ultrasound-guided vein puncture is performed; then, a separate subcutaneous tunnel of 4 cm is created using a tunneling tool. The puncture site and catheter exit site are separate, connected by a subcutaneous tunnel. The catheter is pulled through the tunnel from the exit site to the puncture site.
