Official title
Magnetic Tracking and Electrocardiography-Guided Tip Confirmation System for Placement of Peripherally Inserted Central Catheters
Overview
This prospective study enrolled cancer patients who underwent peripherally inserted central catheter (PICC) placement at a tertiary care oncology hospital in Guangzhou between January 1st and May 30th, 2026. Data on catheterization outcomes and complications were collected to compare two tip positioning techniques: electromagnetic navigation tip positioning and traditional electrocardiogram (ECG)-guided positioning. The outcomes assessed included first-attempt catheterization success rate, tip positioning accuracy, catheterization procedure time, post-procedural catheter adjustment time, and the incidence of complications (thrombosis, infection, and catheter dysfunction) within 4 weeks post-catheterization.
Interventions
- Other Sherlock 3CG Tip Confirmation System
Sherlock 3CG Tip Confirmation System: An integrated system combining magnetic navigation tracking and ECG guidance. It dynamically confirms the tip's position relative to the target anatomical location (e.g., superior vena cava-right atrial junction) by real-time tracking of the catheter tip's spatial position via magnetic navigation and synchronously monitoring ECG signals (e.g., P-wave changes). Traditional ECG-Guided Tip Positioning Technology: Relying solely on ECG monitoring for guidance,
Primary outcome measures
- one time catheterization rate [Time frame: data will be collected on Day 1]
Secondary outcome measures (4)
- time for catheter tip positioning during catheterization [Time frame: on Day 1]
- time for catheter tip adjustment after catheterization [Time frame: on Day 1]
- rate of correct catheter tip positioning [Time frame: on Day 1]
- rate of PICC-related complications [Time frame: within 4 weeks after catheterization]
