Pediatric PICC navigation
Abstract:
Background: Peripherally Inserted Central Catheters (PICC) are widely used for long-term intravenous therapy in pediatric patients and are effective in preventing catheter displacement.
Objective: This study aimed to investigate the effect of magnetic navigation technology compared with ultrasound imaging and manual control of the catheter path.
Methods: The control group underwent PICC placement using the Seldinger technique under ultrasound guidance (n = 86), while the magnetic navigation group received magnet-assisted PICC placement (n = 80). Both groups used chest X-ray (CXR) after catheter placement to confirm the tip position. Insertion time, first-attempt success rate, complication rate, post-procedural pain, post-procedural anxiety, and family satisfaction were compared.
Results: Compared to the control group, magnetic navigation significantly reduced catheter insertion time (28.2 ± 3.67 min vs. 34.85 ± 2.94 min, P < 0.001), improved first-attempt success rate (91.25% vs. 41.86%, P < 0.001), and lowered the complication rate (21.25% vs. 66.28%, P < 0.001). In addition, magnetic navigation alleviated post-procedural pain and anxiety (P < 0.01), and improved family satisfaction (P < 0.01).
Conclusion: Compared to traditional ultrasound-guided methods, magnetic navigation offers superior efficiency in pediatric PICC placement, highlighting its promising potential for clinical application and broader implementation.
