Abstract:
A vasoplegic syndrome is a state of hypotension that develops due to low systemic vascular resistance and is associated with a high mortality rate. Methylene blue is known to improve hypotension and reduce vasopressor requirements by increasing resistance in vasoplegia by inhibiting nitric oxide synthase. Here, we aimed to report on the use and effectiveness of methylene blue to treat severely hypotensive five vasoplegic syndrome cases despite extracorporeal membrane oxygenation. We concluded that Methylene blue can be used as a lifesaving treatment for vasoplegic syndrome refractory to standard supportive treatments, including ECMO.
