[Methylene blue in the therapy of vasoplegic syndrome after cardiac surgery procedure]

Vasoplegic syndrome after cardiac surgery with cardiopulmonary bypass is severe complication with high morbidity and mortality. Without appropriate therapy the syndrome advances to the shock state with subsequent multiorgan failure. Basic haemodynamic parameters of vasoplegic syndrome include low systemic vascular resistance with severe hypotension, tachycardia, and normal or increased cardiac output and low filling pressures. In therapy norepinephrine and vasopressin or its analogues are used. Methylene blue is other therapeutic option. The case of successful application of methylene blue for the treatment of vasoplegic syndrome is presented.
