Abstract
|
|
|
|
Vasoplegic syndrome occurs in 8∼10% of patients following cardiac surgery, and this happens in part because of inducing the inflammatory response. Nitric oxide and guanylate cyclase play an important role in this response, and this is associated with increased morbidity and mortality. For our case, we administered methylene blue (MB), an inhibitor of guanylate cyclase, early after performing cardiopulmonary bypass in a patient with vasoplegic syndrome. The patient recovered immediately after MB administration and maintained an optimal blood pressure without the aid help of any vasopressors.
