Study Notes
Anaphylactic Shock
- Symptoms include swelling, difficulty breathing, and rapid blood loss due to severe allergic reactions.
- Immediate treatment includes administering high-flow oxygen and an intramuscular injection of epinephrine.
- If no improvement is observed, a second epinephrine dose may be required after consulting medical control.
Cardiogenic Shock
- Most common cause is acute myocardial infarction.
- Signs include rapid, irregular pulse; low blood pressure; and potential signs of prior symptoms like arm pain and nausea.
Compensated Shock
- Clinical signs include restlessness, rapid shallow breathing, and cool clammy skin; absent peripheral pulses is NOT a sign.
- If circulatory compensation is adequate, blood flow to non-vital organs is reduced.
Neurogenic Shock
- Occurs due to spinal cord injuries leading to vasodilation, causing blood to pool in the vascular system.
- Often presents with hypothermia.
Septic Shock
- Characterized by bacterial damage to blood vessel walls, leading to leaking and vasodilation.
- Severe infections are the primary cause.
Assessment and Management in Trauma
- Fainting may require checking for injuries even if the patient seems fine.
- Continuous monitoring of the patient's condition and vital signs is necessary during transport.
- Control of bleeding is the first priority in trauma scenarios.
Obstructive Shock
- Can occur due to conditions like cardiac tamponade which prevents the heart from pumping effectively.
- Decompression of the chest may be necessary to prevent fatal consequences in tension pneumothorax cases.
Physiological Responses
- Inadequate circulation is directly referred to as shock.
- Skin pallor in a shock patient is often due to peripheral vasoconstriction as the body attempts to protect vital organs.
Importance of Rapid Transport
- For severe injuries, especially with signs of intrathoracic bleeding, rapid transport to a trauma center is critical for patient survival.
Key Components of Perfusion Triangle
- Perfusion is influenced by the heart, blood vessels, and blood volume.
- Maintaining these components is essential to prevent shock states.
Special Considerations for Older Adults
- Aging can influence the body’s compensatory mechanisms, particularly with gastric emptying, which may increase vomiting risks in shock scenarios.
Definitions
- Compensated shock: Body's mechanism to maintain circulation despite shock.
- Cardiogenic shock: Reduced output and contractility of the heart leading to inadequate perfusion.
- Septic shock: Shock resulting from severe infection leading to systemic inflammation and vasodilation.
