Vasoconstrictor

Vasoactive Drugs for Shock

Phase 4
Recruiting
Led By John P Kress, MD
Research Sponsored by University of Chicago
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Requirement for vasoactive drugs via a central venous catheter for the treatment of shock. Shock will be defined as mean arterial pressure less than 70 mmHg or systolic blood pressure less than 100 mmHg despite administration of at least 1000 mL of crystalloid or 500 mL of colloid, unless there is an elevation in the central venous pressure to > 12 mmHg or in the pulmonary artery occlusion pressure to > 14 mmHg coupled with signs of tissue hypoperfusion (e.g. altered mental state, mottled skin, urine output < 0.5 mL/kg body weight for one hour, or a serum lactate level of > 2 mmol per liter)
Age greater than or equal to 18 years old
Must not have
Severe right heart failure
Cardiopulmonary arrest
Timeline
Screening 3 weeks
Treatment Varies
Follow Up one month, three months, six months, and twelve months after discharge
Awards & highlights

Summary

This trial is testing whether two drugs are better than two other drugs at reducing heart rhythm problems in people with shock who haven't responded to IV fluids.

Who is the study for?
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.Check my eligibility
What is being tested?
The study tests if phenylephrine and vasopressin can better reduce heart rhythm problems than norepinephrine and epinephrine in ICU patients with shock. It's a randomized double-blind trial where treatments are assigned by chance without patient or doctor knowing which one is given.See study design
What are the potential side effects?
Vasoactive drugs like those tested may cause irregular heartbeat, changes in blood pressure, headache, chest pain, weakness and potential complications at the injection site.

Trial Design

2Treatment groups
Active Control
Group I: Norepinephrine and epinephrineActive Control2 Interventions
Patients will receive norepinephrine infusion per standard protocol. Dose range will be 0.03-0.3 mcg/kg/minute. Norepinephrine concentration will be 16 mg/250 mL. If a second vasopressor is required, epinephrine will be added. Dose range of epinephrine will be 0.03-0.3 mcg/kg/minute. Epinephrine concentration will be 16 mg/250 mL. The drugs norepinephrine and epinephrine will be mixed and blinded by the research pharmacy. The research pharmacist will list the dose ranges in mL/hr; this will allow the bedside nurse to program the medication per standard protocol. If the patient's shock is not adequately treated with the highest doses of both norepinephrine and epinephrine, additional, open-label norepinephrine will be added, and titrated to achieve target blood pressure. If the patient's shock is not adequately treated with three vasopressors, additional open-label epinephrine will be added, and titrated to achieve target blood pressure.
Group II: Phenylephrine and vasopressinActive Control2 Interventions
Patients will receive phenylephrine infusion per standard protocol. Dose range will be 0.3 to 3.0 mcg/kg/minute. Phenylephrine concentration will be 160 mg/250 mL. If a second vasopressor is required, vasopressin will be added. Dose range of vasopressin will be 0.1 to 0.6 milliunits/kg/minute. Vasopressin concentration will be 40 units/250 mL. The drugs phenylephrine and vasopressin will be mixed and blinded by the research pharmacy. The research pharmacist will list the dose ranges in mL/hr; this will allow the bedside nurse to program the medication per standard protocol. If the patient's shock is not adequately treated with the highest doses of both phenylephrine and vasopressin, additional, open-label norepinephrine will be added, and titrated to achieve target blood pressure. If the patient's shock is not adequately treated with three vasopressors, additional open-label epinephrine will be added, and titrated to achieve target blood pressure.
