Prophylactic Antibiotics Useful With Antibiotic Impregnated External Ventricular Drains (EVDs)?
What this study is about
The principal objective of this study is to compare the incidence of ventriculostomy related infections (VRIs) in patients who receive twenty-four hours of antibiotics, beginning no more than sixty minutes prior to EVD placement, to the incidence of VRIs in patients who also receive a pre-procedural dose of antibiotics with continued dosing of antibiotics for the duration of the external ventricular drain (EVD). At this time, the duration of prophylactic antibiotic use with antibiotic impregnated EVDs is unknown.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- patients over the age of 18 years
- patients diagnosed with a subarachnoid hemorrhage, intracerebral hemorrhage, or acute ischemic stroke who require an EVD for management of their underlying condition. In certain cases (a small minority), an EVD must be replaced due to failure (i.e., blood clot interrupting flow). In such cases, patients will be re-dosed with antibiotics prior to catheter exchange in typical fashion and continue in their previously randomized treatment group
Exclusion criteria
- patients who were on antibiotics within the week prior to admission
- patients with leukopenia (\<5000) at baseline
- patients with signs of meningitis, ventriculitis or any other infection at presentation
- patients who are pregnant or prisoners
- patients aged \< 18 years old
Where
- The Bronx, New York
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
