Summary
A new computer-assisted navigation system aids pediatric central venous access. This pilot study shows the system is feasible and safe for ultrasound-guided procedures, improving success rates.
Area of Science:
- Pediatric Interventional Radiology
- Medical Device Technology
- Ultrasound-Guided Procedures
Background:
- Central venous catheter placement in children is challenging.
- Ultrasound guidance is recommended but difficult to master.
- A novel navigation system offers visual guidance for needle trajectory.
Purpose of the Study:
- To assess the feasibility and preliminary safety of a computer-assisted needle navigation system for pediatric central venous access.
- To evaluate the usability and effectiveness of the novel system in a pediatric population.
Main Methods:
- Prospective feasibility study involving 10 pediatric patients.
- Procedures performed by expert interventional radiologists using ultrasound and the navigation system.
- Feasibility assessed via user feedback, number of needle passes, and procedure time.
Main Results:
- Successful central venous access achieved in all 10 patients.
- The navigation system was confirmed as feasible by users in all cases.
- 90% of procedures required only a single needle pass, with no complications.
Conclusions:
- The computer-assisted needle navigation system is feasible and safe for pediatric central venous access.
- This technology shows promise for improving ultrasound-guided vascular access in children.

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

442
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
