  1. Nursing Care & Priorities for Those in Shock Keith Rischer RN, MA, CEN

  2. Todays Objectives • Compare and contrast pathophysiology & manifestations of the various shock states and the physiologic compensatory mechanisms. • Identify nursing priorities with the various shock states. • Compare & interpret abnormal laboratory test indicators involved with septic, hypovolemic, and cardiogenic shock. • Analyze assessment data to determine nursing diagnoses and formulate a plan of care for clients with the various shock states. • Describe the medical management and mechanism of action, side effects and nursing interventions of pharmological management with shock states. • Compare & contrast pathophysiology, manifestations, nursing priorities seen with sepsis vs. Multiple Organ Dysfunction Syndrome (MODS).

  3. Shock Defined Any problem that impairs oxygenation delivery to tissues & organs CV system is where it begins Table 40-3 p.826 Hypovolemic Cardiogenic Distributive Neurogenic Anaphylactic Septic-SIRS Multiple Organ Dysfunction Syndrome (MODS)

  4. Processes of Shock Table 40-2 p.825 Initial stage…early shock MAP decrease 5-10mm/Hg Mild vasoconstriction Tachycardic…Why??? Nonprogressive stage…compensatory stage MAP decrease 10-15 mm/Hg Mod. Vasoconstriction Physiologic compensations Renin, aldosterone, ADH Decreased u/o Mild acidosis Mild hyperkalemia

  5. Processes of Shock Table 40-2 p.825 Progressive stage…intermediate stage MAP decrease >20mm/Hg Overall metabolism-anaerobic Moderate acidosis Moderate hyperkalemia Tissue ischemia lactic acidosis-Lactate Refractory stage…irreversible stage

  6. Hypovolemic Shock:Physical Assessment Cardiovascular changes Pulse Blood pressure Skin changes Respiratory changes Oxygen saturation RR Renal and urinary changes Central nervous system changes

  7. Hypovolemic Shock:Nursing Priorities • Impaired gas exchange • Nursing interventions • Deficient fluid volume • Nursing interventions • Decreased cardiac output • Nursing interventions • Risk for ineffective tissue perfusion • Body systems impacted??? • Nursing interventions

  8. Sepsis • Patho • Progressive • Infection • Bacteremia • Systemic Inflammatory Response Syndrome (SIRS) • Sepsis • Severe sepsis • Septic shock • Multiple Organ Dysfunction Syndrome (MODS)

  9. Sepsis:Hyperdynamic (early) Cardiovascular changes Skin changes Respiratory changes Renal and urinary changes Central nervous system changes

  10. Sepsis:Hypodynamic (late) Cardiovascular changes Skin changes Respiratory changes Renal and urinary changes Central nervous system changes

  11. Shock-Laboratory FindingsChart 40-3 p.831 General ABG’s pH CO2 O2 HCO3 Lactate Hct Hgb Potassium Septic Shock Blood cultures WBC Neutrophils Bands C Reactive Protein (CRP) D-Dimer Fibrinogen INR Platelets

  13. General Shock: Nursing Interventions Remember A,B,C,D Reverse the shock Administer O2 Establish IV access Restore fluid volume Colloid Crystalloid Vasoactive gtts Administer blood products as ordered Nursing assessment Pulse/rhythm BP-CVP RR-O2 sats Urine output Skin color Monitor labs

  14. Shock Case Study • 83yr male • Admitted from ED to tele for abd pain and recent lower GI bleeding. Colonoscopy later in day. • PMH: AFib-on Coumadin daily, HTN • Hgb 11.2, INR 2.8, creat .90 • ED VS: T-98.8 P-76 R-16 BP-108/64 sats 98% 2l n/c • Enter room to perform initial assessment: • Pale-diaphoretic, lethargic. Can answer simple questions and oriented x3 • Smell suspicious ?GI bleeding • Note large pool of dark, red blood on pad • VS: P-110 R-24 BP-78/34 sats 90% 2l n/c

  15. Shock Case Study • Nursing priorities… • Rapid Response paged • SBAR to primary MD • Medical/Nursing management: • 2 large bore IV’s • NS 1000cc FF • Prepare for transfer to ICU • Stat Hgb • Obtain 2u PRBC from blood bank

  16. 15” later… • VS: P-100 R-20 BP-92/46 sats 98% 6l n/c • Hgb 8.2 • First unit of blood initiated • Prepare for transfer to ICU…unable to take at this time • Foley catheter placed • VS just before transfer: P-88 R-18 BP-102/64 sats 100% 4l n/c

  17. Septic Shock: Nursing Interventions All the same as previous slide and… Obtain blood, urine cultures as ordered Administer IV abx Administer anti-arrythmics Aggressive IV fluid resuscitation Assess closely for signs of bleeding…DIC Strict aseptic technique Fever reduction as needed Client-family education

  18. Mechanism of Action: Abx

  19. Vasoactive Gtts chart 40-6 p.833 Dopamine Renal Beta effect Alpha effect Levophed (norepinephrine) Phenylephrine (neo-synephrine)

  20. Multiple Organ Dysfunction Syndrome • Patho • Uncontrolled inflammation • Progressive dysfunction of 2 or more systems • Risk factors • Causes • Trauma • Pancreatitis • ARDS • Major surgery

  21. Multiple Organ Dysfunction Syndrome • Four major organ systems involvement • Pulmonary • Renal • Cardiovascular • Coagulation

  22. Physical Assessment Pulmonary CV Renal GI Neuro Coagulation

  23. Diagnostic-Lab Findings Creatinine K+ GFR Troponin BNP Liver Enzymes ALT-AST Alk Phos Total bili Ammonia albumin • ABG • pH • CO2 • O2 • HCO3 • O2 sats • WBC • Platelets • Fibrinogen • PT-INR • Hgb

  24. Therapeutic Management Support tissue oxygenation Fluid resuscitation Blood and blood products Dialysis or CRRT Nutritional support Antibiotic therapy Priority Nursing Diagnoses…
