Aneurysm caused SAH. Nimodipine is a calcium channel blocker but more to prevent vasospasm, which is narrowing of the blood vessel, which is an complication of SAH. During vasospasm, not enough blood is supplied to the brain and a stroke may result. So midodrine, a vasopressor, an alpha agonist was given to elevated the BP. Am I right? i was thinking, patien has past medical history of hypertension. Her BP was high or it was her baseline, her BP was around the 130/90 mmHg for the past few days. So is it ok to give midodrine, will it go higher? Appreciate questions from lovinglife.
