Vasopressors are critical for treating shock, with norepinephrine as the first choice. Future research may identify biomarkers for personalized vasopressor selection and develop new agents.
Area of Science:
- Critical care medicine
- Pharmacology
- Cardiovascular physiology
Background:
- Vasopressors are used for vasodilatory shock unresponsive to fluids.
- They are also used less frequently in cardiogenic and hypovolemic shock.
Purpose of the Study:
- Review vasopressor safety and efficacy.
- Explore pathophysiology, dose-reducing agents, biomarkers, and future research directions.
Main Methods:
- Evidence quality assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE).
Main Results:
- Vasopressors act on various receptors (adrenergic, vasopressin, angiotensin, dopamine).
- Adverse effects include ischemia, hyperglycemia, and arrhythmias.
- Norepinephrine is the first-line agent for vasodilatory shock; vasopressin or epinephrine may be added if refractory.
- Corticosteroids showed mortality benefit in some trials.
- Angiotensin II is useful in profound hypotension; dopamine is reserved for bradycardic patients.
Conclusions:
- Norepinephrine is the primary vasopressor, with vasopressin or epinephrine as alternatives.
- Angiotensin II and dopamine have specific, limited indications.
- Future directions include predictive biomarkers and novel vasopressor development.

Blood Pressure Imbalances and Circulatory Shock
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
