    Study Notes

    External Bleeding Control

    • External bleeding from a femoral artery laceration is challenging to control, especially with good blood pressure.
    • A response to abdominal assault involves immediate transport due to signs of internal bleeding.
    • Dizziness in nontrauma patients often signals internal bleeding.

    Body Systems and Blood Flow

    • The spleen is the least critical component for maintaining adequate blood flow.
    • Skeletal muscle can withstand inadequate perfusion for two to three hours.
    • Hypoperfusion, also known as shock, occurs with low fluid volume and inadequate perfusion.

    Bleeding Management Techniques

    • Direct pressure is the first line of action for bleeding control.
    • A tourniquet is applied when direct pressure fails, specifically above the injury.
    • If bleeding saturates a pressure dressing, additional dressings should be placed on top rather than replacing the one already in use.

    Internal Bleeding Indicators

    • Pale, diaphoretic skin and a rapid pulse indicate shock, particularly in pelvic fractures.
    • Signs of intra-abdominal bleeding include abdominal pain and distension.
    • Hematemesis suggests gastrointestinal bleeding.

    Safety and Assessment Considerations

    • High blood pressure and certain medications can aggravate bleeding and complicate treatment.
    • Use of a compression device is essential for stabilizing pelvic fractures.
    • A patient on anticoagulants like rivaroxaban poses higher bleeding risks.

    Pediatric Considerations

    • Infants with a total blood volume of 800 mL show shock symptoms after losing 100 mL of blood.

    Tourniquet Application

    • The tourniquet is only to be removed in a hospital setting, as it may lead to renewed bleeding if released prematurely.

    Vital Signs and Shock

    • Vital sign instability, particularly hypotension, typically surfaces after a significant blood volume loss (over 20%).
    • Elderly patients may first show weakness or dizziness as an indicator of nontraumatic internal bleeding.

    Cardiovascular Compensation

    • The cardiovascular system's ability to handle blood loss correlates with the rate of bleeding rather than baseline metrics.
    • Capillary bed functions as a link between arterioles and venules, facilitating nutrient exchange.

    Hemostasis and Blood Clotting

    • Platelets aggregate at injury sites to promote clotting after tissue injury, critical for stopping bleeding.
    • Hemophilia causes spontaneous bleeding events due to a deficiency in blood clotting factors.

    Measurement and Treatment Techniques

    • External bleeding from veins tends to be easier to control due to lower pressure.
    • A larger radius bleed typically requires special management strategies, including the use of hemostatic agents.
    • For treating severe nosebleeds, having patients lean forward and pinch their nostrils is recommended.

    Overall Management

    • Focus remains on managing bleeding via techniques emphasizing direct pressure, tourniquet use, and rapid patient assessment for timely transport or further intervention.
