- oncotic pressure
- hypovolemic shock
- Use of dopamine (Intropin) in cardiogenic shock
- What is anaphylactic shock characterized by?
- What is cardiogenic shock characterized by?
- a 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
- b DECREASED: CO, stroke volume, UO, ventricular emptying, tissue perfusion, blood pressure, LOC.
- c to reverse low BP effect of nitroglycerin and morphine (MS) by elevating BP to perfuse vital organs. Causes peripheral vasoconstriction (alpha 1) and increases the force of contraction (beta 1 w/ IV fusion only). Potential to cause tachycardia.
- d Vasodilation, Capillary permeability, Bronchospasm
- e absolute volume loss or relative volume loss as with ascites (3rd spacing) - 10-31% mortality rate.
5 Multiple Choice Questions
- intra-aortic ballon pump (IABP)
- bleeding out
- Spinal cord injury, Spinal anesthesia, depressant action of medications, lack of glucose (insulin reaction or shock), Severe pain.
- vasodilation (lowers BP) and increased capillary permeability/leakage d/t cellular injury from bacterial toxins- lose fluid out of vasculature.
5 True/False Questions
Sequence of events for hypovolemic shock → 1. Decreased circulating volume 2. decreased venous return 3. decreased stroke volume, 4. decreased CO, 5. decreased cellular oxygen supply, 6. impaired tissue perfusion,
7. impaired cellular metabolism.
Medical management of neurogenic shock → O2, control chest pain, selective fluid support, medications (dopamine, dobutamine, isoproterenol, norepinephrine, IV nitro)
Medical management of hypovolemic shock → 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)
Nursing considerations during cardiogenic shock → vital signs, electrolyte imbalance, I&O, correct acidosis
Medical management of septic shock → Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.
