Clinical Trial Summary

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.


Description:

Midodrine is an alpha 1 receptor agonist used usually in cases of hypotension helping to increase blood pressure. The main indication is orthostatic hypotension but there are other clinical conditions where this medicament is often used like hypotension by dialysis, hepatorenal syndrome and after carotid artery stenting.

Vasoplegic syndrome coul be interpreted as a variant of orthostatic hypotension that happens usually after surgical interventions. It produces a loss of systemic vascular resistance due to inflammatory reaction without any signs of infection.

The investigators aim to conduct a randomized, double-blind, single-center, placebo-controlled study of midodrine in patients who present postoperative vasoplegia with no active signs of sepsis but need of vasoactive drugs (Noradrenalin).

Intervention

Drug:
Midodrine Hydrochloride
All patients become standard care resuscitation treatment using liquids and vasoactive drugs in order to get a median arterial pressure = 65 mmHg. Midodrine will be administered according to the evolution of the patient's mean pressure.
Placebo
All patients become standard care resuscitation treatment using liquids and vasoactive drugs in order to get a median arterial pressure = 65 mmHg. Placebo will be administered according to the evolution of the patient's mean pressure.
