Summary
The electromagnetic catheter locating system (EMCLS) for central venous access device (CVAD) placement significantly reduces radiation exposure and cost compared to fluoroscopy. Accuracy of placement is maintained, offering a safer and more economical alternative for patients requiring CVADs.
Area of Science:
- Medical Devices
- Interventional Radiology
- Patient Safety
Background:
- Chronic venous access devices (CVADs) are essential for medication and nutrition delivery.
- Fluoroscopy is typically used to confirm correct CVAD placement.
- Minimizing radiation exposure and cost are key considerations in medical procedures.
Purpose of the Study:
- To compare the electromagnetic catheter locating system (EMCLS) with fluoroscopy for CVAD placement.
- To evaluate differences in radiation exposure, cost, and accuracy between the two methods.
Main Methods:
- A retrospective chart review of patients undergoing CVAD placement at UNM Hospital and UNM Cancer Center.
- Inclusion criteria: age >20 years, central CVAD placement via fluoroscopy or EMCLS.
- Data collected included radiation exposure, complications, cost, and placement accuracy.
Main Results:
- No significant differences in patient demographics, complications, or operating room times between groups.
- Both fluoroscopy and EMCLS demonstrated equal accuracy in catheter tip placement.
- EMCLS resulted in significantly lower mean patient radiation exposure (30 mRem vs. 771 mRem) and reduced costs.
Conclusions:
- EMCLS is a viable alternative to fluoroscopy for CVAD placement.
- Utilizing EMCLS reduces patient radiation exposure and healthcare costs.
- The accuracy of CVAD placement is not compromised when using EMCLS.
