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.
