- Two symptoms common to all types of shock?
- Causes of neurogenic shock?
- a mental confusion and oliguria
- b the 'pushing force', pushing the fluid out of the capillaries. It's the result of the actual pressure of the fluid on the capillary walls.
- c Spinal cord injury, Spinal anesthesia, depressant action of medications, lack of glucose (insulin reaction or shock), Severe pain.
- d Adequate cardiac pump
Sufficient blood volume
- e vital signs, electrolyte imbalance, I&O, correct acidosis
5 Multiple choice questions
- monitor HR, BP, LOC, urine output. Recognize early and manage to reduce chance of end-stage organ damage. Provide pt teaching regarding drug therapy.
- Treat underlying cause (may need surgery),
Fluid and blood replacement (colloids-albumin; crystalloids (NS and LR)
Redistribution of fluid - modified Trendelenburg
Medications - dopamin (Intropine) & dobutamine (Dobutrex) (only if adequate intravascular fluid)
- MI, arrhythmias, valvular disease, cardiac surgery, cardiomyopathy.
- MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
- also called 'colloid osmotic pressure', is the 'pulling force', pulling fluids from the surrounding tissue into the capillaries. It's the result of a difference in the concentration of solutes in the fluid inside the capillaries as opposed to outside them
5 True/False questions
What is anaphylactic shock characterized by? → Vasodilation, Capillary permeability, Bronchospasm
hypovolemic shock → absolute volume loss or relative volume loss as with ascites (3rd spacing) - 10-31% mortality rate.
Shock → vasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.
Sequence of events for hypovolemic shock → previous exposure to allergen with resulting antibody formation - exposure again to substance - develops a systemic antigen-antibody reaction - mast cells are provoked to release potent vasoactive substances, ie histamine or bradykinin - widespread vasoD and cap perm - Decreased venous return to heart - Decreased stroke volume - Decreased CO - Decreased BP - Decreased tissue perfusion - Respiratory arrest - Cardiac arrest - Death
what is the universal blood type → MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
