Using low-dose vasopressors through peripheral catheters in ICU patients
Official title: The PULSE Study - The Peripheral Use of Low-dose Vasopressors for Safety and Efficacy in the Intensive Care Unit: a Pilot Feasibility Study
Run by Queen's University · NCT06920173 · Data updated 2026-11-12
This study is testing if giving low-dose vasopressors through regular IVs can safely help critically ill patients in the ICU instead of using more invasive central lines.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults aged 18 or older experiencing shock who do not have a central line or PICC line already placed.
✕Probably not a fit
Patients who require urgent dialysis or those needing more than two vasopressors to maintain blood pressure may not benefit from this study.

What this trial studies
This study investigates the safety and efficacy of administering low-dose vasopressors through peripheral venous catheters (PVCs) in critically ill patients in the intensive care unit (ICU). Traditionally, vasopressors are delivered via central venous catheters (CVCs), which can lead to complications such as infections and thrombosis. The study aims to determine if PVCs can be a viable alternative, potentially expediting treatment and reducing the risks associated with CVC placement. By conducting a randomized control trial, the researchers hope to provide high-quality data to support the use of peripheral vasopressors in managing shock.
Why it matters
Potential benefit: If successful, this approach could improve patient outcomes by allowing faster and safer administration of vasopressors in critically ill patients.
How similar studies have gone: While previous observational studies have suggested the safety of peripheral vasopressor use, this randomized control trial represents a novel approach to validate these findings.
