TYPES OF SHOCKS !! Flashcards
Hypovolemic Shock
Causes: Dehydrations, bleeding, burns
S/s: increased HR, decreased BP, restless, anxious
Decreased- CO/CVP/PAWP/HgB w/ bleed
Increased- SVR (compensatory)/ Lactate/ NA (hypernatermia)
Treatment: NS fluids ( 3 for 1), blood products
Nursing Care: Hemodynamic monitoring, monitor lung sounds, monitor UO
Cardiogenic Shock
Causes: L ventricular MI, Trauma
S/S: similar to HF, crackles, JVD, increased HR, decreased BP, weak pulses (abrupt !)
Increased- CVP/ PAWP/ SVR
Decreased- CO/SV
Treatment: ionotropics, vasopressors, diuretics, antidysrhythmics, IABP, VAD, ECHMO
Distributive shock: vessel prob: lack tone
Anaphylactic Shock
Causes: antigen/ aggressor
S/S: massive vasodilations + bronchcontriction, rash, laryngeal edema, stridor, wheezing, decreased LOC, N/V/D, decreased BP/CO/CVP/PAWP/SVR, increased HR
Treatment: Remove antigen, Epi, benadryl, corticosteroids, fluids, ionotropes, vasopressor, tylenol
Nursing Care: Monitor BG
Distributive shock: vessel prob: lack tone
Neurogenic Shock
Causes: T6 increases injury, drugs, improper spinal anesthesia
* Parasympathetic system runs unopposed -> loss of sympathetic tone -> inability to tighten up
S/s: bradycardia, hypoTN, hypothermia
Decreased CO/CVP/PAWP/SVR
Treatment: DVT prophylaxis, fluids ( SBP < 90, UO < 30) , vasopressors, atropine, pacemakers, pt warming
Distributive shock: vessel prob: lack tone
Septic Shock
Sepsis: Tachycardia, Tachypnea, PaCO2 < 32, temp > 38 < 36
* interventions, successful
Septic Shock: Sepsis w/ hypoTN despite fluid (3rd spacing) resuscitation
* no response to interventions
**Microorganism -> SIRS -> activation of coagulation cascade -> organ death
**
Diagnostics: Left shift leukocytosis (bandemia), blood cultures ( -> broad spectrum), increased CRP, coag abnormalities, increased Lactase
S/S: increase HF, TEMP, PaCo2 ( first a decrease), decrease BP,LOC, UO, RR (late), SVR, CVP, PAWP
widened pulse pressure, bounding pulse, warm skin, crackles w/ lung infections
Treatment: trend lactate, blood cultures x2, pan cultures, broad anx -> narrow NS fluids, vasopressors (epi drip), maintain CO+ BG
- measure serum lactate
- blood cultures
- broad spectrum ABX
- crystalloid for decrease BP + lactate > 4
- Vasopressors
- Persistent arterial hypotension
* target CVP > 8, CV O2 > 70
- low dose steriods
- glucose control
- resp. management
Obstructive Shock
cancer/tumor blocking organ blood flow
