II. Definitions

  1. Shock
    1. Impaired tissue oxygenation and perfusion
    2. Imbalance in delivery and consumption of oxygen and metabolic substrates
    3. Numerous causes and mechanisms, but 4 general types: Hypovolemic, Distributive, Cardiogenic, Obstructive

III. Pathophysiology: Shock

  1. Circulatory insufficiency resulting in inadequate oxygen supply for given demand
  2. Triggers a cascading metabolic spiral culminating in cell injury and cell death
    1. Intracellular Calcium overload
      1. Free radical oxidative damage
      2. Impaired mitochondrial ATP synthesis
      3. Impaired Muscle relaxation and myocardial contractility
    2. Metabolic Acidosis
      1. Results from anaerobic metabolism, Lactic Acidosis, and Renal Failure
      2. Increases Calcium overload
      3. Decreases myocardial and other Muscle contractility
      4. Decreased Catecholamine response
      5. Increased Interstitial Edema
    3. Pro-inflammatory Cytokines (e.g. Interleukins, Tumor Necrosis Factor)
      1. Limited to specific shock types (e.g. Septic Shock, Anaphylaxis)
      2. Systemic vasodilation secondary to endothelial cell activation and nitric oxide release
  3. Compensatory mechanisms (Blood Pressure may be normal when compensation is adequate)
    1. Cardiac Output increase
      1. Responds to Catecholamine and Cortisol release
    2. Arterial Vasoconstriction
      1. Selective shunting of Blood Flow from the skin, skeletal Muscle, Kidney and Gastrointestinal Tract
    3. Venous constriction
      1. Increases Preload and return of blood to heart and brain
    4. Increased Sodium and water reabsorption
      1. Antidiuretic Hormone
      2. Renin-Angiotensin System
  4. Failed compensation
    1. Metabolic Acidosis
    2. Coagulopathy (including Disseminated Intravascular Coagulation)
    3. Inflammatory mediator release
    4. Multiorgan dysfunction and death
    5. Hypotension

IV. Types

  1. Precautions: Undifferentiated Shock
    1. Many shock presentations are combinations of more than one shock type
    2. Septic Shock is primarily Distributive Shock, but also associated with third spacing and Hypovolemic Shock
    3. A massive tension pneumo-Hemothorax may cause both obstructive shock and Hypovolemic Shock
  2. Hypovolemic Shock
    1. Defined as intravascular fluid volume that is insufficient for adequate end-organ perfusion
    2. Hemorrhagic Shock (acute blood loss)
      1. Examples: Trauma (most common), Ruptured Abdominal Aortic Aneurysm, GI Bleed
    3. Dehydration
      1. Examples: Acute Gastroenteritis with Vomiting, Diarrhea, Diabetic Ketoacidosis
    4. Third-Spacing
      1. Examples: Burn Injury, Pancreatitis
  3. Distributive Shock
    1. Defined as systemic vasodilation that renders an otherwise sufficient circulating volume to be inadequate
      1. Hemodynamic parameters are paradoxically opposite other forms of shock
      2. SVR decreases (primary) and Cardiac Output, Pulse Pressure, SvO2 and ScvO2 increases
    2. Adrenal crisis
      1. Fever may be present (as in Septic Shock)
    3. Septic Shock
      1. Systemic inflammatory response with diffuse, peripheral vasodilation and decreased Cardiac Output
    4. Neurogenic Shock (esp. cervical and upper thoracic spinal cord injury above T6)
      1. Loss of sympathetic nervous function
      2. Results in decreased vascular tone, Hypotension with paradoxical Bradycardia
      3. Neurogenic Shock does not cause a narrowed Pulse Pressure (sympathetic reflex)
      4. Contrast with Spinal Shock (below T6 Level), which results in Flaccid Paralysis below the lesion
    5. Anaphylaxis
      1. Mast Cell degranulation
      2. Cytokine-induced vasodilation
  4. Cardiogenic Shock
    1. Defined as cardiac pump failure (decreased Cardiac Index <1.8, increased left heart filling pressures)
    2. Congestive Heart Failure
    3. Cardiomyopathy (e.g. Viral Myocarditis, cardiotoxic agents)
    4. Trauma (e.g. Cardiac Contusion)
    5. Supraventricular Tachycardia or other Arrhythmias
    6. Structural heart defects (e.g. valvular rupture, left to right shunt)
  5. Obstructive Shock
    1. Defined as heart or Great Vessel obstruction to flow with decreased Preload or increased Afterload
    2. Tension Pneumothorax
    3. Pericardial Tamponade
    4. Massive Pulmonary Embolism (increased RV Afterload, RV bowing limits LV filling)

V. Causes (Mnemonic: SHRIMP CAN)

  1. Septic Shock
  2. Hypovolemic Shock (e.g. Hemorrhagic Shock, severe Dehydration)
  3. Respiratory Compromise (e.g. Tension Pneumothorax, massive Pulmonary Embolism)
  4. Ingestion (toxin, Overdose)
  5. Metabolic (e.g. DKA, Adrenal Insufficiency, Hypothyroidism)
  6. Psychiatric (Water Intoxication)
  7. Cardiogenic Shock (MI, CHF, Cardiac Tamponade)
  8. Anaphylactic shock

Ontology: Dehydration (C0011175)

Definition (MEDLINEPLUS)

When you're dehydrated, your body doesn't have enough fluid to work properly. An average person on an average day needs about 3 quarts of water. But if you're out in the hot sun, you'll need a lot more than that. Most healthy bodies are very good at regulating water. Elderly people, young children and some special cases - like people taking certain medications - need to be a little more careful.

Signs of dehydration in adults include

  • Being thirsty
  • Urinating less often than usual
  • Dark-colored urine
  • Dry skin
  • Feeling tired
  • Dizziness and fainting

Signs of dehydration in babies and young children include a dry mouth and tongue, crying without tears, no wet diapers for 3 hours or more, a high fever and being unusually sleepy or drowsy.

If you think you're dehydrated, drink small amounts of water over a period of time. Taking too much all at once can overload your stomach and make you throw up. For people exercising in the heat and losing a lot of minerals in sweat, sports drinks can be helpful. Avoid any drinks that have caffeine.

Definition (NCI_CTCAE) A disorder characterized by excessive loss of water from the body. It is usually caused by severe diarrhea, vomiting or diaphoresis.
Definition (NCI) A condition resulting from the excessive loss of water from the body. It is usually caused by severe diarrhea, vomiting or diaphoresis.
Definition (NCI_NCI-GLOSS) A condition caused by the loss of too much water from the body. Severe diarrhea or vomiting can cause dehydration.
Definition (NAN) Decreased intravascular, interstitial, and/or intracellular fluid. This refers to dehydration, water loss alone without change in sodium.
Definition (MSH) The condition that results from excessive loss of water from a living organism.
Definition (PSY) State of excessively reduced body water or water deficit.
Definition (CSP) condition that results from excessive loss of water from a living organism.

Ontology: Shock (C0036974)

Definition (MSH) A pathological condition manifested by failure to perfuse or oxygenate vital organs.
Definition (MEDLINEPLUS)

Shock happens when your blood pressure is too low and not enough blood and oxygen can get to your organs and tissues. Causes of shock include internal or external bleeding, dehydration, burns, or severe vomiting and/or diarrhea. All of these involve the loss of large amounts of body fluids. Shock often accompanies injury.

Specific types of shock include

  • Hypovolemic shock, caused by internal or external bleeding
  • Septic shock, caused by infections in the bloodstream
  • Anaphylactic shock, caused by a severe allergic reaction
  • Cardiogenic shock, caused by the inability of the heart to pump blood effectively
  • Neurogenic shock, caused by damage to the nervous system

Symptoms of shock include cold and sweaty skin, weak but rapid pulse, irregular breathing, dry mouth, dilated pupils and reduced urine flow. Shock is life threatening and it is important to get help right away. Treatment of shock depends on the cause.

National Institute of General Medical Sciences

Definition (NCI) A life-threatening condition that requires immediate medical intervention. It is characterized by reduced blood flow that may result in damage of multiple organs. Types of shock include cardiogenic, hemorrhagic, septic, anaphylactic, and traumatic shock.
Definition (CSP) a profound hemodynamic and metabolic disturbance characterized by the failure of the circulatory system to maintain adequate perfusion of vital organs; causes inadequate delivery of nutrients and insufficient removal of cellular waste products to and from the tissues.
