Summary

Radiation doses from common venous access procedures are generally low. Even in outlier cases, doses are unlikely to cause skin effects when performed by experienced professionals with calibrated equipment.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Patient Safety

Background:

  • Venous access procedures are common in clinical practice.
  • Radiation exposure is a concern during fluoroscopically guided interventions.
  • Understanding radiation dose is crucial for patient safety and quality assurance.

Purpose of the Study:

  • To retrospectively analyze radiation dose data for six common venous access procedures.
  • To evaluate radiation exposure levels associated with different venous access techniques.
  • To identify procedures with potentially higher radiation doses.

Main Methods:

  • Retrospective analysis of radiation dose data from 1010 venous access procedures.
  • Data collected from a quality assurance database between 1998 and 2004.

  • Statistical analysis including descriptive statistics, logarithmic transformation, ANOVA, and Tukey's HSD test.

    • Main Results:

    • No procedure exceeded 950 mGy cumulative dose or 760 mGy peak skin dose.
    • Tunneled dialysis catheter placements showed the highest mean doses (cumulative, dose-area product, and peak skin).
    • Significant dose differences were found between tunneled and nontunneled catheter placements.

    Conclusions:

    • Radiation doses from venous access procedures are typically low.
    • Skin effects from radiation are unlikely, even in outlier cases.
    • Operator expertise and equipment calibration are important factors in minimizing radiation exposure.
