Nursing management

Definition

Reference

Is occurring when the heart has been damaged to the point where it is unable to pump enough blood to the organs as body need. As a result of that, blood pressure begins to fall and organs may begin to fail.

Is a serious condition of a full-body inflammatory response as a complication of an infection where toxins can leads to life-threatening low blood pressure.

  • Pharmacologic therapy
  • Monitoring hemodynamic status
  • Administering medications and IV fluids
  • Maintaining Intra-Aortic balloon counter pulsation
  • Enhancing safety and comfort

Medical management

Causes

  • Treatment of the underlying cause
  • Fluid and blood replacement
  • Redistribution of fluid
  • Pharmacologic therapy

Gram-negative and gram-positive bacteria.

Collaborative care

  • Drug therapy

Signs & symptoms

Medical management

  • Oxygen
  • Nutritional therapy
  • Sedatives
  • Surgery if needed

  • Increased CO in ABG and decreased SVR
  • Low BP
  • Low urine output

Nursing management

  • Hemodynamic monitoring
  • Physiotherapy should be used if there are clinical signs of a chest infection
  • Nutritional support.
  • Oxygen therapy
  • Fluid/electrolyte management

Collaborative care

  • Drug therapy
  • Vasopressor (e.g., dopamine)
  • Inotropes (e.g., dobutamine)
  • Anticoagulation (e.g, low-molecular-weight heparin)
  • Antibiotic as ordered

Objectives

Signs & symptoms

Nursing management

  • consider as one of life threating condition
  • The care providers must appreciate the physiologic and pathologic effects and management of the shock
  • And understanding of some vasoactive medication that is essential for a proper management.

  • Administering blood and fluid safely
  • Hemodynamic monitoring
  • Monitor intake and output.
  • Assess color and amount of urine.
  • Medication administration
  • Monitor serum electrolytes
  • Nutritional support

  • Tachycardia
  • Hypotension
  • a narrowed pulse pressure

Causes

Medical management

Collaborative care

Types of Shock and their classification

  • Drug therapy:
  • Vasopressor (e.g., dopamine)

  • MI
  • Cardiomyopathies
  • blunt cardiac injury

  • Correction of underlying causes
  • Initiation of first-line treatment:
  • Oxygenation
  • Pain control
  • Hemodynamic monitoring
  • Laboratory marker monitoring
  • Fluid therapy

The participants will be able to:

  • Describe the organ damage that may occur with shock
  • Compare hypovolemic, cardiogenic and distributive shock in terms of causes, pathophysiologic effects and describe the medical and nursing management
  • Identify the vasoactive medications used in treating shock and describe the nursing implication associated with their use

Definition of shock

  • Low Blood Flow
  • Maldistribution of Blood Flow

"Shock, is a life-threatening medical condition that in which widespread perfusion to the cells is inadequate to deliver oxygen and nutrients to support vital organs and cellular function."

( VonRueden, Bolton & Vary 2008, p313)

Definition

Is an acute and life-threating hypersensitivity (allergic) reaction to a sensitizing substance

Low Blood Flow

Compensatory stage

Maldistribution of Blood Flow

In the compensatory stage, the body activates neural, hormonal, and biochemical compensatory mechanisms in an attempt to overcome the increasing consequences of anaerobic metabolism and to maintain homeostasis.

(Renee Gagliardi,2010)

  • Cardiogenic
  • Hypovolemic
  • Absolute Hypovolemic
  • Relative Hypovolemic

  • Neurogenic
  • Anaphylactic
  • Septic

Definition

Causes

Causes

Nursing management

Is a hemodynamic phenomenon that can occur within 30 minutes of a spinal cord injury at the fifth thoracic (T5) vertebra or above and last up to 6 weeks.

  • Spinal cord injury
  • Spinal anesthesia
  • Or other nervous system damage

Severe allergic reaction when patient who have already produced antibodies to foreign substance (antigen) develop a systematic antigen-antibody reaction.

Stages of Shock

  • The nurse must be knowledgeable about the clinical signs of anaphylaxis
  • Must be prepared to begin CPR if cardiorespiratory arrest occurs

Signs & symptoms

Anaphylactic Shock

Collaborative care

  • Drug therapy
  • Antihistamines (e.g., diphenhydramine)
  • Epinephrine
  • Bronchodilators nebulized
  • Corticosteroids (if hypotension persists)
  • hydrocortisone (after initial resuscitation)

  • Hypotension
  • Bradycardia
  • an inability to regulate temperature
  • massive vasodilation

  • Compensatory stage
  • Progressive stage
  • Irreversible stage

  • Definition

  • Signs & symptoms
  • Medical management
  • Nursing management
  • Collaborative care :
  • (Oxygenation, Circulation ,Drug therapy , Supportive therapies )

Medical management

  • Stabilizing of spinal cord injury
  • Specific treatment depend on the cause of shock
  • If hypoglycemia is the cause, glucose is rapidly administered

Progressive stage

Irreversible stage

The progressive stage of shock begins as compensatory mechanisms fail. In this stage, aggressive interventions are necessary to prevent development of multi organ dysfunction syndrome.

(Renee Gagliardi,2010)

Collaborative care

The irreversible (or refractory) stage of shock represents that point along the shock continuum at which organ damage is so severe that the patient does not respond to treatment and cannot survive.

(Renee Gagliardi,2010)

  • Drug therapy :
  • Vasopressors (e.g., phenylephrine)
  • Atropine (for bradycardia)

Nursing management

Medical management

Signs & symptoms

  • Positioning the patient properly
  • Supporting cardiovascular and neurologenic function until the usually transient episode of neurogenic shock resolve.

  • Removing the causative antigen
  • Administering medication that restore vascular tone
  • Providing emergency support of basic life function

  • Dizziness
  • Tachycardia
  • chest pain
  • Shortness of breath
  • Incontinence
  • swelling of the lips and tongue
  • wheezing and stridor.
