No experience at all using it here, but I know its an old inhibitor of nitric oxide used in refractory vasoplegia.

I have no experience with this drug. I attach one letter to editor (is in spanish but you can get some references from it).

Yes; I'm familiar with its use in this context from a cardiac unit I used to work in and I know it has been used in PICU for refractory hypotension with at least case reports of success, but I have not seen any data for use in neonates.  When I have proposed its use in extreme cases in my current NICU, everyone is concerned that the nitric oxide inhibition will precipitate pulmonary hypertensive crisis.
