Study Notes
Shock
- Shock is a life-threatening condition where the body's circulatory system fails to deliver enough oxygen and nutrients to tissues and organs.
- It's characterized by inadequate tissue perfusion, which can lead to cellular damage and organ dysfunction.
- Several types of shock exist, each with distinct causes and characteristics.
- Hypovolemic shock results from a significant loss of blood volume, often due to hemorrhage or dehydration.
- Cardiogenic shock arises from the heart's inability to pump blood effectively, often caused by a myocardial infarction or heart failure.
- Distributive shock involves a dilation of the blood vessels, leading to reduced blood pressure and inadequate tissue perfusion; this can be caused by sepsis, anaphylaxis, or neurogenic shock.
- Obstructive shock is caused by a blockage in the blood flow to the heart or great vessels, e.g. a tension pneumothorax.
- Common symptoms of shock include rapid, weak pulse, low blood pressure, cool, clammy skin, altered mental status, and decreased urine output.
Sepsis
- Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.
- It's a serious complication of infection, often progressing from a local infection to a systemic inflammatory response.
- The initial infection can originate from anywhere in the body, such as the lungs (pneumonia), urinary tract, or abdomen.
- A key feature of sepsis is the dysregulation of the immune system. The body's response to the infection becomes harmful, causing widespread inflammation and damage.
- The inflammatory response can lead to organ dysfunction, and if untreated, shock and death.
- Common signs and symptoms of sepsis can be non-specific, including fever, chills, rapid heart rate, rapid breathing, altered mental status, and decreased urine output.
- Sepsis is diagnosed based on clinical criteria, considering the patient's infection, presence of systemic inflammatory response (SIRS), and evidence of organ dysfunction.
Sepsis and Shock
- Sepsis is a frequent cause of distributive shock.
- The inflammatory response in sepsis leads to widespread vasodilation, resulting in decreased blood pressure and reduced tissue perfusion.
- Untreated sepsis can progress rapidly to septic shock, further compromising the circulatory system and causing irreversible organ damage.
- Early recognition and prompt treatment of sepsis are crucial to improve patient outcomes.
- Early intervention includes measures to optimize fluid resuscitation, control infection, and support organ function.
