After a brain injury, there is a serious concern for secondary damage caused by intracranial hypertension and pressure. This hypertension is usually monitored using surgical means, which can be invasive and dangerous when conditions are critical.
Recently, a study on severe pediatric brain injury found that the non-invasive Transcranial Doppler is as effective at detecting dangerous signs of intracranial hypertension as traditional surgical methods. Additionally, the Transcranial Doppler can be used within minutes of the injury, which may provide an opportunity to treat more quickly and avoid further damage.
