permissive hypotension
Controlled resuscitation strategy allowing lower blood pressure to minimize bleeding in trauma patients.
Full Definition
Permissive hypotension is a resuscitation strategy in trauma care where blood pressure is deliberately maintained at lower than normal levels to minimize ongoing hemorrhage while preserving adequate organ perfusion. This approach aims to prevent disruption of initial hemostatic clots that may occur with aggressive fluid resuscitation. Target systolic pressures typically range from 80-90 mmHg in the absence of traumatic brain injury. The strategy is contraindicated in patients with head trauma where cerebral perfusion pressure must be maintained. Documentation should specify target pressures and rationale for this approach.
Usage
Usage note: Always document target pressure parameters and contraindications when implementing this strategy.
