Heparin therapy: a randomized prospective study

J R Wilson, J Lampman

    American Heart Journal
    |February 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Continuous and intermittent heparin therapy showed similar major bleeding complication rates. However, soft-tissue trauma and prolonged Lee-White Clotting Times (LWCT) increased bleeding risk, suggesting LWCT monitoring can help reduce complications.

    Area of Science:

    • Medical research
    • Clinical trials
    • Pharmacology

    Background:

    • Heparin therapy is widely used for anticoagulation.
    • Understanding bleeding risk factors associated with different heparin administration methods is crucial for patient safety.

    Purpose of the Study:

    • To compare the incidence of bleeding complications between continuous and intermittent heparin therapy.
    • To identify specific patient factors and procedural risks associated with heparin-induced bleeding.

    Main Methods:

    • Randomized controlled trial involving eighty patients.
    • Assignment to either continuous or intermittent heparin therapy.
    • Monitoring of anticoagulation using the Lee-White Clotting Time (LWCT).

    Main Results:

    Related Experiment Videos

    • Overall major bleeding complications occurred in 7.5% of patients.
    • No significant difference in major bleeding rates between continuous (5%) and intermittent (10%) heparin groups.
    • Bleeding complications were significantly higher in patients with soft-tissue trauma (e.g., thoracenteses, cut-downs) and LWCTs > 35 minutes for two consecutive days.

    Conclusions:

    • Heparin administration method (continuous vs. intermittent) does not significantly impact major bleeding risk.
    • Soft-tissue trauma and prolonged anticoagulation monitoring (LWCT > 35 minutes) are significant risk factors for bleeding complications.
    • Laboratory monitoring with LWCT may aid in reducing heparin-related bleeding complications.
