What should the mean arterial blood pressure (SBP) be maintained at in TBI patients?

In the management of traumatic brain injury (TBI) patients, maintaining an adequate mean arterial blood pressure (MAP) is crucial for ensuring sufficient cerebral perfusion. The correct answer indicates that the ideal target for systemic blood pressure in these scenarios is above 110 mmHg.

Maintaining blood pressure above this threshold helps to prevent secondary brain injury caused by inadequate cerebral perfusion. When the MAP is too low, the brain may not receive enough oxygen and nutrients, exacerbating the effects of the initial injury and potentially leading to worse outcomes. Elevating blood pressure to this level supports cerebral autoregulation and helps to ensure that the brain is adequately perfused, especially in the presence of conditions that may lead to increased intracranial pressure.

The focus on keeping blood pressure above the critical level of 110 mmHg reflects evidence-based guidelines that emphasize the importance of aggressive management of blood pressure to improve outcomes in TBI patients. Monitoring and interventions are often required to achieve this target, which might involve fluid resuscitation and sometimes the use of vasopressors.

Conversely, targets that are too low can lead to insufficient blood flow to the brain, while excessively high targets can increase the risk of hypertension-related complications. Therefore, a careful balance is essential in
