- Medical management of neurogenic shock
- Causes of hypovolemic shock
- Sequence of events for anaphylactic shock
- Use of norephinephrine (Levophed) in cardiogenic shock
- Body's compensatory mechanisms for shock
- a Increased HR, vasoconstriction, activates renin angiotensin mechanisms, ADH increases, increase secretion of epinephrine and norepinephrine to increase BP and HR.
- b Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.
- c 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
- d hemorrhage, severe burns, dehydration (vomiting, diarrhea, diuresis), ascites, GI bleed, ruptured aneurysms, third spacing.
- e Vasoconstriction alpha 1 stimulator
5 Multiple choice questions
- Invasive procedures, Drug therapy, Fluid therapy, Surgical and traumatic wounds, Immunosuppressive therapy.
- vasodilation d/t ALLERGIC REACTION causing release of HISTAMINE.
- 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)
- Loss of sympathetic tone (disruption of SNS)
Skin warm and dry, decreasd BP, Decreased HR, Decreased Temperature.
- vasodilation d/t nerve injury and suppression of SNS.
5 True/False questions
3 organs most concerned about with shock → brain, heart, kidneys (cells with high metabolic rates
What are the INTRINSIC precipitating factors for septic shock → Extremes of age, Immunosuppression, Chronic illness, Malnutrition.
Nursing considerations during cardiogenic shock → I&O, VS, ECG, CNS checks, electrolytes, clotting times, respiratory status, hemodynamic monitoring, and family needs.
Nursing concerns for neurogenic shock → vital signs, electrolyte imbalance, I&O, correct acidosis
distributive shock → MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
