Nimodipine is a calcium channel blocker that is used to prevent or treat cerebral vasospasm after subarachnoid hemorrhage. It works by relaxing the smooth muscle of the cerebral arteries and improving blood flow to the brain. Nimodipine is the only FDA-approved agent for vasospasm and has been shown to reduce the risk of ischemic complications and improve neurological outcomes12. Lorazepam, propranolol, and pentobarbital are not effective for treating cerebral vasospasm and may have adverse effects on the patient’s blood pressure, heart rate, and level of consciousness.

Epidural hematoma

An epidural hematoma is a collection of blood that forms between the skull and the dura mater, the outermost layer of the meninges that cover the brain. The most common cause of an epidural hematoma is a head injury that fractures the temporal bone and tears the middle meningeal artery, which runs along the inner surface of the skull. Arterial bleeding is under high pressure and can rapidly expand the hematoma, compressing the brain and causing neurological deterioration. A typical symptom of an epidural hematoma is a brief loss of consciousness followed by a lucid interval and then a rapid decline in consciousness and brain function. This condition requires urgent surgical evacuation of the hematoma to prevent brain damage or death12. Venous bleeding, clot formation, and intracranial aneurysm are not the main factors associated with the deterioration of the patient’s condition in this case.
