A 50 year old female is found down and brought by paramedics to the emergency departement. GCS is 7, and the patient is intubated for airway protection. The patient withdraws all extremities to painful stimuli. A stat head CT reveals the above abnormalities.
An angiogram is performed, and the source of the bleeding is found and secured. The patient is admitted to the neurological intensive care unit.
This patient still remains at risk for mortality from which of the following causes (choose the one best answer)?

ANSWERS AND EXPLANATIONS
A) Anemia
This answer is incorrect.
This patient has suffered a subarachnoid hemorrhage. If a patient survives the initial event, the two most feared complications are rebleeding and vasospasm. In this patient, the risk of rebleed has been reduced by intravascular coiling of the causative aneurysm. The patient remains at risk for vasospasm, which can result in infarction and death.
This patient is at increased risk for anemia, but the concern for vasospasm is greater.

B) Hypertension
This answer is incorrect.
This patient has suffered a subarachnoid hemorrhage. If a patient survives the initial event, the two most feared complications are rebleeding and vasospasm. In this patient, the risk of rebleed has been reduced by intravascular coiling of the causative aneurysm. The patient remains at risk for vasospasm, which can result in infarction and death.
This patient may have increased blood pressure after a subarachnoid hemorrhage, and may require nitroprusside or another antihypertensive. However, the central venous pressure should be kept supranormal to help prevent vasospasm and infarction.
