MORA-ORDONEZ, J.M. et al. Use of methylene blue in the treatment of vasoplegic syndrome of post-operative heart surgery. Med. Intensiva [online]. 2006, vol.30, n.6, pp.293-296. ISSN 0210-5691.

Vasoplegia is a frequent complication in post-operative heart surgery and determines a significant increase in morbidity-mortality. When vasoplegia persists in spite of optimized fluid therapy with the use of Swan-Ganz catheter, we have a safe, effective and economical alternative, methylene blue. We present the case of a patient who developed vasoplegia refractory to treatment and shock in the scheduled post-operative period of myocardial revascularization. The use of a single dose of methylene blue resolved the hemodynamic instability and allowed for total discontinuation of vasoactive drugs. Thus, we present this new indication of methylene blue, still not approved by the corresponding bodies, for which no national publications have been found and its clinical management and the absence of adverse effects after its use.
