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.

| Sherlock 3CG Tip Confirmation System | Other | 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, it assists in determining the tip position via characteristic waveform changes in intracardiac ECG signals (e.g., changes in P-wave amplitude) derived from the catheter tip electrode as the tip approaches the target location, serving as a conventional positioning method. |
