hemodynamically unstable
Clinical state where blood pressure and perfusion parameters are inadequate to maintain organ function.
Full Definition
A critical clinical condition characterized by inadequate circulatory function with compromised tissue perfusion, typically manifesting as hypotension, tachycardia, altered mental status, and decreased urine output. In emergency surgery contexts, hemodynamic instability often indicates ongoing blood loss, sepsis, or cardiovascular compromise requiring immediate intervention. The condition necessitates aggressive resuscitation and may preclude detailed diagnostic workup in favor of immediate operative management.
Usage
Usage note: Specify vital sign parameters and response to interventions when documenting instability.
In Context
- "The patient remained hemodynamically unstable despite aggressive fluid resuscitation and required immediate surgery." — Emergency surgery consultation
- "Hemodynamically unstable trauma patients bypass CT imaging and proceed directly to the operating room." — Trauma protocol documentation
