About this study

Official title: Manipulation of Arterial Pressure Early in Non Thrombolysed Acute Ischemic Stroke: Effects on Death and Neurological Disability

This is a controlled clinical trial among non thrombolysed acute ischemic stroke patients to determine the effects of three levels of arterial pressure on death and neurological disability. After the admission in the vascular unit of the Emergency Department the patients are randomized to maintain during the first 24h the Systolic Arterial Pressure in tree levels of pressure: 140 to 160 mmHg; 161 to 180 mmHg and 181 to 200 mmHg. The end point of the study is the Modified Rankin score and mortality in three month after the discharge.

Read the detailed description

To maintain the tree levels of systolic arterial pressure during de first 24h we will use one of the two strategies:1) infusion of 500 to 1000ml of saline solution and/or norepinephrine solution to increase de systolic pressure or 2) infusion of esmolol or nitroprussiate solution to decrease de pressure. Every patient will have a transcranial doppler study in the first 24h to measure the mean velocity of cerebral arteries.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Esmolol, Sodium Nitroprussiate (NPS) or Norepinephrine (NOR)Drug

    Also called Esmolol, NPS or NOR

    Esmolol(2,5g /10ml + SG5% 240ml = 10mg/ml). Start with a bolus of 500mcg/kg in 1 min (ou 0,5mg/kg)and maintain the dose of 50mcg/kg/min (or 0,05mg/kg/min). Increase de infusion in 25mcg/kg/min after each 5 min until the randomized SAP or if the heart beat is lower than 60. The maximum dose is 200ug/kg/min (ou 0,2 mg/kg/min). If the randomized SAP do not reach the goal pressure with the maximum dose of esmolol, start a infusion of sodium nitroprussiate (NPS).

    NPS (50mg + SG5% 250ml= 200mcg/ml). No bolus. Start the infusion with 0,2 mcg/kg/min and maintain 0,5 a 5mcg/kg/min. Increase de dose each 15 min to a maximum of 10mcg/kg/min.

    NOR: (8mg/8ml + SG5% 242ml=32mcg/ml)No bolus. Start 1 to 5 mcg/min to a maximum dose of 20mcg/min.

  • Esmolol, NPS or NORDrug

    We use one of the three drug to manipulate the systolic arterial pressure

Questions about this trial

What is this clinical trial studying?

A study testing Esmolol, Sodium Nitroprussiate (NPS) or Norepinephrine (NOR), Esmolol, NPS or NOR and manipulation of SAP in people with Stroke, Acute, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 31 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Luiz A Nasi, Physician (55 51 9982 18 44, lnasi@terra.com.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ranking score and mortality (time frame: Three month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00848770, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Dec 2009.
