Why would an ICU patient be on Viagra BID (off label use?)

[Roland]

A client that my wife cared for in an ICU environment had Viagra prescribed BID. This was a post-op CABG scenario. Is there an off label use for the drug not in Davis where this would be appropriate?

tried to look at your link but it said it required a subscription. I would love to read the article though. I am a cardiology nurse and would love to learn more about this if anyone has similar documentation.
