Təsvir
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).

| Active Comparator: Intervention group Midodrine will be administered every 8 hours, increasing the dose gradually until a maximum of 30 mg a day is reached. It will be given orally in the following sequence: 2.5 mg - 5 mg - 7.5 mg - 10 mg. The target standard perfusion pressure for all the patients will be a mean arterial pressure (MAP) > 65 mmHg, with unchanged dose of midodrine after target pressure is reached. If the pressure continues to increase, the same sequence will be followed for dose de-escalation. | Drug: Intervention group 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 Comparator: Control group By placebo group will be followed the same strategy.The target standard perfusion pressure for all the patients will be a mean arterial pressure (MAP) > 65 mmHg, with unchanged dose of placebo after target pressure is reached. If the pressure continues to increase, the same sequence will be followed for dose de-escalation. | Drug: Control group 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. |
