Study Notes
Shock Management
- Apply a tourniquet proximal to a lacerated area for severe bleeding control.
- Septic shock results from poor vessel function and substantial volume loss.
- Assist ventilation, thermal management, and elevating lower extremities are critical for spinal injury patients with low blood pressure.
Trauma and Shock Types
- Rapid transport to a trauma center is vital for patients with signs of shock from intrathoracic bleeding.
- Psychogenic shock involves temporary vasodilation and syncope due to sudden nervous system reactions.
- Blood pressure may be the last measurable change in patients showing signs of shock.
Signs and Symptoms
- A post-operative elderly female with tachycardia and low blood pressure is likely experiencing septic shock.
- Conditions commonly misidentified as shock include severe infection and anaphylaxis, but ischemic stroke does not typically present as shock.
- Capillary sphincters regulate blood flow through capillaries and are essential for perfusion adjustments.
Causes and Types of Shock
- Cardiogenic shock can arise from increased afterload or heart attack but not increased preload.
- Clinical signs of compensated shock do not include absent peripheral pulses.
- Distributive shock stems from widespread vasodilation, causing blood pooling in vascular beds.
Fluid Loss and Shock Types
- Hypovolemic shock from burns results in plasma loss, affecting fluid balance.
- Neurogenic shock often accompanies hypothermia due to spinal injuries.
- Both pulmonary edema and impaired ventilation occur in cardiogenic shock.
Body Responses and Metabolism
- Shock signifies a state of hypoperfusion to body cells, necessitating immediate attention.
- Carbon dioxide, a waste product of cellular metabolism, must be expelled by the lungs.
- In the event of shock, blood flow is redirected away from less essential organs, such as the skin.
Emergency Interventions
- Cardiac tamponade most likely causes obstructive shock among various injuries.
- Wheezing is a clinical sign unique to anaphylactic shock.
- Decompression of the chest is essential for preventing death from tension pneumothorax.
Shock Evaluation
- A patient with absent radial pulses and dilated pupils is in decompensated shock.
- Anaphylactic shock reactions worsen upon subsequent exposure to an allergen due to sensitization.
- Hemorrhagic shock is most likely caused by a severe liver laceration.
