How do you treat a GI bleed without endoscopy?

The following question comes from an overseas EMCast listener who asks:

"...speaking of UGI bleeds, it's a diagnosis with which we are essentially helpless (i.e., definitive therapy) because we have no Gastroenterologist. I was just curious what you considered effective modalities and drugs for GI bleed without endoscopy."

What are your thoughts on the non-endoscopic management of GI bleeds?
