vasopressor
Medication that constricts blood vessels to increase blood pressure and improve circulation.
Full Definition
A class of medications that cause vasoconstriction, thereby increasing vascular resistance and blood pressure. Vasopressors are critical in pediatric intensive care for managing distributive shock, severe hypotension, and cardiovascular collapse when fluid resuscitation alone is insufficient. Common pediatric vasopressors include dopamine, epinephrine, and norepinephrine, each with specific indications and requiring careful titration based on hemodynamic response and potential side effects.
Usage
Usage note: Often used in plural when referring to multiple agents simultaneously.
