permissive hypotension
Controlled resuscitation strategy maintaining lower-than-normal blood pressure to minimize bleeding in trauma patients.
Full Definition
A damage control resuscitation strategy that deliberately maintains systolic blood pressure at 80-90 mmHg in trauma patients with uncontrolled hemorrhage until definitive hemostasis is achieved. This approach minimizes clot disruption and reduces additional blood loss that can occur with aggressive fluid resuscitation to normal pressures. Permissive hypotension is contraindicated in patients with traumatic brain injury due to the need for adequate cerebral perfusion pressure. The strategy requires careful monitoring and immediate transition to normotensive goals once bleeding is controlled surgically.
