Overview

Stroke-associated pneumonia (SAP) is a grave complication of stroke and one of the most important predictors for patients' poor outcomes. Stroke associated pneumoniaSAP and other infections limited the overall efficacy of stroke management. Increasing evidence suggests that sympathetic nervous system activity contributes to post post-stroke immunosuppression and emergence of infections. This study is designed to test the safety and efficacy of an adrenergic β receptor blocker propranolol in reducing SAP in hemorrhagic stroke patients, in a multi-center, randomized, open-labeled, end point-blinded, trial.

Description

This study will enroll 168 intracerebral hemorrhage patients who meet the inclusion criteria.

ICH patients meet the inclusion criteria will be randomly assigned at a 1:1 ratio into groups of standard treatment (blank-controlled), or propranolol hydrochloride injection .

Patients allocated to experimented group will be intravenously given initial dose at 5mg propranolol hydrochloride daily over a course of 7 consecutive days, The primary purpose of this study is to compare propranolol hydrochloride with standard treatment on reducing the 7-day risk of pneumonia when initiated within 24 hours of symptom onset in intracerebral hemorrhage.

Both intent analysis (ITT) and per-protocol (PP) were used for analysis.

Eligibility

Inclusion Criteria:

  1. Age 18 years older and less than 80 years.
  2. Onset of new neurological deficits within≤24 hours at the time of randomization
  3. CT scan demonstrates supratentorial parenchymal hemorrhage and volume of hematoma≥10ml .
  4. Initial NIHSS score of 11 or greater and less than 25 scores.
  5. Initial GCS score (aggregate of verbal, eye, and motor response scores) of 8 or greater at time of enrollment.
  6. Admission without infection signs.
  7. Signed and dated informed consent by the subject, legally authorized representative, or surrogate obtained.

Exclusion Criteria:

  1. Subjects is considered a candidate for immediate surgical intervention by the neurosurgery service, including surgical evacuation of hematoma, decompressive craniectomy, minimally invasive aspiration of hematoma, and ventricular shunt or external ventricular drainage for intracerebral hemorrhage into the ventricle.

  3. Previous stroke or pre-onset motor disability (mRS≥1)
  4. Pregnancy or parturition within previous 30 days or active lactation.
  5. Use of beta blockers (propranolol, metoprolol, sotalol, carvedilol, bisoprolol, atenolol, esmolol, etc.) or reserpine within the last 30 days.
  6. Bronchial asthma or chronic obstructive pulmonary disease
  7. Cardiogenic shock or severe or acute heart failure.
  8. Degree II-III atrioventricular block or sinus bradycardia or heart rate ≤65/min.
  9. Known sensitivity to propranolol.
  10. Severe hepatic or renal insufficiency
  11. History of Malignancy
  12. Currently participating in other interventional clinical trials.
  13. Immunosuppressant therapy or known immunosuppression.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
