Some experts suggest a combination use of different vasopressors with different mechanism of action (e.g. norepinephrine, vasopressin and angiotensin ii) to reduce the dose of each drug, limit side effects, and individualise vasopressor therapy, in similar way to broad spectrum antibiotic therapy. whether this concept will translate into. Vasopressors are a powerful class of drugs that induce vasoconstriction and thereby elevate mean arterial pressure (map). vasopressors differ from inotropes, which increase cardiac contractility; however, many drugs have both vasopressor and inotropic effects. although many vasopressors have been used since the 1940s, few controlled clinical.

Vasopressors and inotropes are medications used to create vasoconstriction or increase cardiac contractility, respectively, in patients with shock. the hallmark of shock is decreased perfusion to vital organs, resulting in multiorgan dysfunction and eventually death. vasopressors increase vasoconstriction, which leads to increased systemic vascular resistance (svr). increasing the svr leads to. In conclusion, inotropes and vasopressors play an essential role in the supportive care of a number of important cardiovascular disease processes. to date, prospective examination of their impact on clinical outcomes in randomized trials has been minimal, despite their widespread use in cardiovascular illness. Vasoactive agents can be categorized by their activity and are often divided into two types: vasopressors and inotropes. the term vasopressor refers to a class of drugs that cause vasoconstriction. typically, increasing vasoconstriction leads to an increase in systemic vascular resistance (svr), which leads to an increase in blood pressure. the.

Continuous vasopressor inotropic infusions must be administered via infusion pump to prevent interrupted flow, unexpected changes in flow rates, and undesired boluses. vasopressors have a short half life and duration of action, so they require continuous infusion and rapid titration, usually every 5 to 15 minutes. Shock complicates one third of intensive care unit (icu) admissions and is a strong risk factor for icu mortality, with progressive circulatory failure accounting for approximately 20% of all icu deaths and more than 40% of deaths in patients with shock. 3–5 vasopressor dependent shock carries an average 28 day mortality of approximately 35%.
