The use of metaraminol as a vasopressor in critically unwell patients: a narrative review and a survey of UK practice

Abstract

Major international guidelines state that norepinephrine should be used as the first-line vasopressor to achieve adequate blood pressure in patients with hypotension or shock. However, recent observational studies report that in the United Kingdom and Australia, metaraminol is often used as second line medication for cardiovascular support.
