Hemorrhagic Stroke
Conditions
Brief summary
Because of its pharmacokinetic characteristics, such as short half-life and its safety profile, esmolol hydrochloride is a beta blocker suitable for venous use in the form of continuous infusion. Strategies that improve the blood pressure control of patients with hemorrhagic stroke during the first hours of hospitalization are determinant in controlling the hematoma expansion and determining factor in its prognosis. This study was designed with the objective of evaluating the beneficial effects of combining esmolol hydrochloride with sodium nitroprusside for the blood pressure control of participants with hemorrhagic stroke.
Detailed description
Participants with parenchymal intracranial hemorrhage (diagnosis confirmed by computed tomography or magnetic resonance imaging), and: * with systolic pressure \> 150 mmHg, * not contraindicated for treatment with beta-blockers, * who can start the drug treatment within 6 hours of the stroke, * having a target of ≤ 140 mmHg of systolic pressure within 1 hour after initiation of treatment.
