Study Notes
Capillaries and Venules
- Capillaries connect arterioles to venules, facilitating the exchange of oxygen and nutrients with tissues.
Early Signs of Intra-Abdominal Bleeding
- Initial indicators include abdominal pain and distention; significant hypotension and ecchymosis appear later.
Primary Assessment Focus
- During a primary assessment, severe hemorrhage, airway obstruction, and breathing patterns are prioritized. Capillary bleeding typically receives less immediate attention.
Geriatric Patient Indicators
- In older adults, weakness or dizziness may signal nontraumatic internal bleeding without a history of trauma.
Understanding Hypoperfusion
- Hypoperfusion, also termed shock, indicates inadequate blood flow to tissues, leading to cellular death if untreated.
Hemophilia Characteristics
- Patients with hemophilia may experience spontaneous bleeding; it does not enhance clotting with aspirin.
Management of External Bleeding
- Direct pressure on the wound is the first action for controlling severe external bleeding from extremities.
Gastrointestinal Bleeding Symptoms
- Hematemesis (vomiting blood) is a primary symptom indicating potential gastrointestinal bleeding.
Definition of Perfusion
- Perfusion refers to the circulation of blood within an organ in sufficient amounts to meet the metabolic needs of the body.
Blood Volume and Vital Signs
- Significant changes in vital signs can occur after losing more than 20% of total blood volume.
Severity of Bleeding Assessment
- Assessing bleeding severity includes considering clinical signs and symptoms, general appearance, and mechanism of injury; systolic blood pressure alone is insufficient.
Managing Severe Bleeding in Specific Cases
- In cases of external abdominal bleeding, assisting in patient ventilations is crucial while managing external hemorrhage.
Importance of Organ Tolerance
- Skeletal muscle can endure inadequate perfusion for up to 2 hours, unlike other vital organs that may sustain damage more quickly.
Actions After Direct Pressure Failure
- If direct pressure doesn't stabilize severe extremity bleeding, a tourniquet should be applied proximally to the injury site.
