Successful use of methylene blue following out of hospital cardiac arrest: a case report

While already established in vasopressor resistant septic shock and post-cardiopulmonary bypass vasoplegia, this case highlights the potential role of methylene blue as an adjunct therapy in post out of hospital cardiac arrest vasoplegia, particularly when conventional therapies fail. The dose of methylene blue used was substantially lower than that reported in prior studies of sepsis and cardiac surgery. Further studies are warranted to define the timing, dosing, and clinical impact of methylene blue in this setting.
