Nontraumatic Intracerebral Hemorrhage, Multiple Localized Clinical Trial
Official title:
Clevidipine (Cleviprex®) Compared With Urapidil (Ebrantil®) for Blood Pressure Reduction in Patients With Primary Intracerebral Hemorrhage: A Randomized Controlled Trial
Intracerebral hemorrhage (ICH) is responsible for 10-15% of primary strokes. ICH is a dynamic process with three phases: initial hemorrhage, followed by hematoma expansion and perihematoma edema formation. Hematoma volume is correlated with disease progression and outcome. Contemporary evidence proposes that elevated blood pressure is associated with hematoma expansion while more than 90% of patients with ICH present with acute hypertension. Uncontrolled blood pressure is a leading cause of ICH and it seems also to be a factor of poorer outcomes. Therefore, rapid reduction and control of blood pressure might ease disease progression and improve the outcome. Clevidipine (Cleviprex®), an ultrashort-acting dihydropyridine calcium channel antagonist, with its rapid onset and short duration might be more effective than conventional antihypertensives to achieve rapid blood pressure control in patients with acute ICH.
After admission to the ICU the patients presenting with primary intracerebral hemorrhage (ICH) are evaluated for enrollment. If systolic blood pressure (SBP) is higher than 160 mmHg or SBP <160 mmHg under intravenous antihypertensive drug (e.g. Urapidil), started less than 3 h before randomization, the patient will be randomized in one of the two study groups and intravenous therapy with Clevidipine (Cleviprex®) or Urapidil (Ebrantil®) will start immediately. Data of systemic haemodynamics will be collected continuously by online monitoring, starting at baseline and ending after 24h (study data measurements). In particular, all blood pressure measurements are extracted via an arterial line, which is placed as standard of care in these patients. If the target values are not attained within 30 minutes, the investigators can add or switch to alternative antihypertensive drugs of their choice. 24h after initiation of Clevidipine (Cleviprex®) or Urapidil (Ebrantil®), all patients receive Nicardipine (Cardene®) (standard care in daily clinical routine) for another 24h followed by orally administered antihypertensive medication. Intracerebral hematoma volume will be determined by readings of noncontrast brain computed tomography (CT) scans using the ABC/2 rule to calculate the volume. As a standard in these patients a CT scan is performed 6 hours after admission to the ICU. ;
