SECONDARY, DISEASES, ACUTE LIVER FAILURE, CRITICALLY ILL
Critically ill patients with primary brain injury or with cerebral damage secondary to extra-cerebral diseases (i.e. acute liver failure, drug intoxication) are at risk of developing intracranial hypertension (IHT) [Because of the invasive nature of ICP measurement techniques, many other non-invasive methods have emerged in recent years as surrogates or “triage” tools for ICP estimation, such as transcranial Doppler [In this setting, a well-studied but under valuated phenomenon in clinical practice is the ICP waveform (ICPW) [
