Evaluation of Superior Mesenteric Artery Diameter and Flow in Aneurysmal Subarachnoid Hemorrhage Patients Undergoing Hypertensive Therapy for Cerebral Artery Vasospasm

The purpose of this research study is to determine if the diameter and flow of the superior
mesenteric artery in patients with aneurysmal subarachnoid hemorrhage undergoing hypertensive
therapy for cerebral artery vasospasm are effected enough to justify withholding enteral
nutrition.

Study measurements of the diameter and Doppler flow velocity of the superior mesenteric
artery (SMA) using abdominal ultrasound in order to evaluate the potential additional risk of
non-occlusive mesenteric ischemia (NOMI) and non occlusive bowel necrosis (NOBN) in patients
undergoing hypertensive therapy for cerebral vasospasm in Aneurysmal Subarachnoid Hemorrhage
(aSAH), to justify the withholding of enteral nutrition.

Inclusion Criteria:

- Patient diagnosed with aSAH

Exclusion Criteria:

- Hemodynamic instability

- Already receiving vasopressor therapy

- Non-aneurysmal SAH

- Intracranial hemorrhage of other cause

- Not anticipated to receive hypertensive therapy with vasoactive medications for
cerebral vasospasm from SAH or suspected aSAH

- Unable to visualize SMA using ultrasound

- Pregnancy
