hypovolemic shock
Học thuậtThân thiện
Definition
Noun: A life-threatening medical condition characterized by a state of inadequate tissue perfusion and cellular oxygen delivery, resulting from a significant and rapid decrease in circulating blood volume. This is caused by severe hemorrhage (blood loss) or substantial loss of other body fluids.
Usage
This term is used exclusively in medical and emergency contexts to describe a specific type of shock. It is a clinical diagnosis. - The primary cause of hypovolemic shock is acute volume loss. - Treatment for hypovolemic shock focuses on rapid fluid resuscitation and controlling the source of loss.
Examples
- The patient was admitted to the emergency department in hypovolemic shock following a major car accident.
- Severe dehydration from cholera can lead to hypovolemic shock.
- The surgical team worked quickly to replace fluids and blood, aiming to reverse the hypovolemic shock.
Advanced Usage
- Stages of Hypovolemic Shock: The condition is often described in stages (e.g., compensated, decompensated, irreversible) based on the percentage of volume lost and the body's physiological response.
- Distributive vs. Hypovolemic Shock: In medical differential diagnosis, hypovolemic shock (from loss of volume) is contrasted with distributive shock (from abnormal blood vessel dilation, as in sepsis).
Variants and Related Words
- Hypovolemia (noun): The state of decreased blood volume, which is the precursor to hypovolemic shock. Not all hypovolemia leads to shock.
- Hemorrhagic Shock (noun): A specific subtype of hypovolemic shock caused explicitly by blood loss.
Synonyms
- Volume Depletion Shock: A less common but descriptive synonym.
- Oligemic Shock: A technical synonym emphasizing the deficient blood volume.
