Nursing Care & Priorities for Those in Shock

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

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
