    This study establishes normal hemorrhagometry values in children aged 4-14. Cold exposure significantly prolongs bleeding time and increases blood loss, unlike Ivy

    Area of Science:

    • Pediatric Hematology
    • Hemostasis and Thrombosis Research
    • Clinical Physiology

    Context:

    • Establishing normal reference ranges for hemostasis parameters is crucial for pediatric diagnostics.
    • Hemorrhagometry is a method used to assess bleeding characteristics.
    • Understanding the impact of environmental factors like temperature on bleeding is clinically relevant.

    Purpose:

    • To determine normal hemorrhagometry values in a pediatric cohort (ages 4-14).
    • To evaluate the effect of cold exposure (17°C) on bleeding parameters.
    • To compare hemorrhagometry results with the Ivy bleeding time method.

    Summary:

    • Normal ranges for bleeding time, hemoglobin loss, and bleeding intensity were established in 43 children.
    • Cold exposure (17°C) significantly prolonged bleeding time, increased bleeding intensity, and elevated hemoglobin loss compared to room temperature measurements.

  • Hemorrhagometry at room temperature yielded longer bleeding times than the Ivy method. No correlation was found between hemorrhagometry parameters and age, sex, or thrombocyte count (above 100,000/mm³).

    • Impact:

    • Provides essential reference data for pediatric bleeding disorder assessment.
    • Highlights the significant influence of cold stress on bleeding dynamics in children.
    • Offers comparative insights into different bleeding time measurement techniques.
