Vasoactive Drugs for Shock
What You Need to Know Before You Apply
What is the purpose of this trial?
The investigators hypothesis is that for ICU patients with shock, the use of the vasoactive drugs phenylephrine and vasopressin will reduce tachydysrhythmias when compared to norepinephrine and epinephrine. To investigate this hypothesis, the investigators are conducting a randomized double blind controlled trial comparing phenylephrine and vasopressin vs. norepinephrine and epinephrine in ICU patients with shock that is not responsive to IV fluids. All patients admitted to the adult intensive care units at the University of Chicago will be screened for eligibility.
Do I need to stop my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
How is the drug combination of Phenylephrine and Vasopressin unique for treating shock?
The combination of Phenylephrine and Vasopressin is unique for treating shock because they are both pure vasoconstrictors, meaning they work by narrowing blood vessels to increase blood pressure, unlike other treatments that may also affect heart function. This makes them particularly useful in cases where increasing vascular tone is the primary goal.12345
What data supports the effectiveness of the drug for treating shock?
Research shows that norepinephrine is recommended as a first-line treatment for septic shock, and vasopressin can be effective when other drugs are not working. Combining norepinephrine with other drugs like phenylephrine or vasopressin has been studied in critically ill patients, suggesting potential benefits in managing shock.56789

Are You a Good Fit for This Trial?
This trial is for adults in the ICU with shock not improved by IV fluids, needing drugs through a central vein to manage blood pressure. It's not for those with severe right heart failure, cardiopulmonary arrest, or pregnant women.Inclusion Criteria
