Umbilical vascular catheters: localization by two-dimensional echocardio/aortography

L George, J D Waldman, M L Cohen

    Pediatric Cardiology
    |January 1, 1982
    PubMed
    Summary

    Echocardiography accurately and safely positions umbilical vascular catheters in neonates. This imaging method is superior to X-rays for venous catheters and equally effective for arterial catheters, avoiding radiation exposure.

    Area of Science:

    • Neonatal critical care
    • Pediatric cardiology
    • Medical imaging

    Background:

    • Umbilical vascular catheters are essential for critically ill neonates.
    • Accurate catheter tip placement is crucial for patient safety and treatment efficacy.
    • Traditional methods like roentgenography carry risks such as radiation exposure.

    Purpose of the Study:

    • To evaluate the accuracy of 2-dimensional echocardio/aortography for umbilical vascular catheter tip localization.
    • To compare the efficacy of echocardiography versus roentgenography in determining catheter position.
    • To assess the advantages of echocardiography in neonatal catheter placement.

    Main Methods:

    • Prospective study involving 55 consecutive infants requiring umbilical vascular catheters.

  • Catheter tip position determined using 2-dimensional echocardio/aortography.
  • Comparison with traditional thoraco-abdominal roentgenography for localization accuracy.

    • Main Results:

    • Echocardio/aortography showed high correlation (sr = .90) with roentgenography for umbilical arterial catheters (N=50).
    • Echocardiography proved more accurate than roentgenography for umbilical venous catheter tip localization.
    • Contrast echocardiography confirmed cardiac chamber position for venous catheter assessment.

    Conclusions:

    • Two-dimensional echocardio/aortography is a reliable method for umbilical vascular catheter tip localization.
    • Echocardiography offers superior accuracy for venous catheter placement compared to X-ray.
    • Advantages include avoidance of ionizing radiation, no need for patient repositioning, and direct visualization of catheter-cardiovascular relationships.
