When dealing with a traumatic brain injury, what sign is indicative of increased intracranial pressure?

In the context of traumatic brain injury, Cushing's triad is a classic sign indicative of increased intracranial pressure. This triad consists of three key clinical findings: hypertension (elevated blood pressure), bradycardia (decreased heart rate), and irregular respirations. The presence of Cushing's triad suggests that the body is responding to increased pressure within the skull, often due to swelling, bleeding, or other complications that can compromise circulation and oxygenation to the brain.

While slurred speech, pupil dilation, and seizures may be associated with brain injuries and can indicate neurological impairment, they do not specifically point to increased intracranial pressure as reliably as Cushing's triad. Slurred speech may indicate brain damage or concussion, pupil dilation can arise from various factors including drug effects or nervous system issues, and seizures may occur in response to brain injuries but can occur independently of intracranial pressure changes. Therefore, recognizing Cushing's triad is crucial in the prehospital setting as it guides immediate intervention and prioritization of care for the patient with a traumatic brain injury.
