In an attempt to control massive upper gastrointestinal tract hemorrhage, levarterenol (8 mg in 100 ml saline) was instilled into the stomachs of 12 massively and actively bleeding patients on 13 separate occasions. The hemorrhage was controlled in seven instances (54%). This mode of therapy can be instituted simply, promptly, and safely, and its use as the initial therapeutic attempt to stop upper gastrointestinal tract hemorrhage is warranted.
