Subarachnoid haemorrhage

Also known as Aneurysmal SAH · Subarachnoid bleed · Thunderclap headache

Subarachnoid haemorrhage — the non-traumatic bleeding into the subarachnoid space, usually from a ruptured intracranial aneurysm; the thunderclap headache (the worst headache of my life, the maximal intensity within seconds to minutes); the CT sensitivity (98 per cent within 6 hours), the lumbar puncture for the xanthochromia if the CT is negative or the presentation is delayed; the nimodipine 60 mg every 4 hours for the vasospasm prophylaxis; the BP control; the aneurysm securing by the endovascular coiling or the surgical clipping; and the complications (the rebleeding, the vasospasm at day 4 to 14, the hydrocephalus, the hyponatraemia).
