Vasoplegic syndrome is characterized clinically by reduced systemic vascular resistance and
normal or increased cardiac output. It is principally observed in cardiovascular and
orthopedic interventions and is characterized by a systemic inflammatory response with the
inability of the vascular endothelial muscles to contract and a resistance to the action of
vasoactive drugs. This event extends the length of stay in the critical care area due to the
need of vasoactive drugs.
The investigators aim to assess the standardized application of midodrine in postoperative
patients without sepsis and need of vasoactive drugs in order to reduce the length of stay in
critical care area and for extension in hospital.
