Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Are there variations in the practice between clinicians, hospitals or countries? If yes, are they associated with clinical outcome?
* What are the health economic impacts associated with receiving vasopressors?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
By contrast to septic shock, there is no uniform definition of postoperative vasoplegia. Receipt of any amount of vasopressor would provide an objective dichotomous definition but a limitation would be the inability to differentiate degrees of vasodilation. Use of a threshold dose of infused vasopressor to determine a definition is uncomfortably arbitrary. There have been trials of different vasopressors to treat postoperative vasoplegia in cardiac surgical patients and we intend to gather data to inform future design in noncardiac surgery.
In addition, there is evidence of substantial variation in the management of postoperative hypotension between centres, countries and continents. The variation is in assessment (cardiac output and invasive monitoring) and environment (post-operative care units, high-dependency units, ICUs) and management (use and choice of fluids and vasopressors/inotropes). We hypothesise that there is also variation in the incidence of organ dysfunction and the use of organ support, and in clinical outcomes including duration of stay and mortality.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* No plans for return home on the day of surgery, for medical reasons
* Age ≥ 18 on day of surgery
Exclusion Criteria
