[Seizures associated with acute subarachnoid hemorrhage. Emergency diagnosis and treatment].

Seizures and convulsive status in patients with subarachnoid haemorrhage are an emergency. They are not only known to increase cerebral metabolic rate but also cerebral blood flow and intracranial pressure and rebleeding can occur in patients with an unclipped aneurysm. The goal of therapy is to stop the seizures minimizing the risk of secondary brain damage (hypoxia, hypotension, hypercarbia, hyperthermia). Several active drugs are available for treating seizures, it is important to identify the cause, prompt administration, monitoring the patients and choosing the one with less side effects.
