There is tentative evidence of benefit for tranexamic acid which inhibits clot breakdown. Somatostatin and octreotide, while recommended for varicial bleeding, have not been found to be of general use for non variceal bleeds. After treatment of a high risk bleeding ulcer endoscopically giving a PPI once or a day rather than as an infusion appears to work just as well and is less expensive (the method may be either by mouth or intravenously). Variceal bleeding
For initial fluid replacement, colloids or albumin is preferred in people with cirrhosis. Medications typically include octreotide or, if not available, vasopressin and nitroglycerin to reduce portal venous pressures. Terlipressin appears to be more effective than octreotide, but it is not available in many areas of the world. It is the only medication that has been shown to reduce mortality in acute variceal bleeding. This is in addition to endoscopic banding or sclerotherapy for the varices. If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. If bleeding continues, balloon tamponade with a Sengstaken-Blakemore tube or Minnesota tube may be used in an attempt to mechanically compress the varices. This may then be followed by a transjugular intrahepatic portosystemic shunt. In those with cirrhosis, antibiotics decrease the chance of bleeding again, shorten the length of time spent in hospital, and decrease mortality. Octreotide reduces the need for blood transfusions and may decrease mortality. No trials of vitamin K have been conducted.
Gastrointestinal bleeding (GI bleed), also called gastrointestinal hemorrhage (GIB), is all forms of bleeding in the gastrointestinal tract, from the mouth to the rectum. When there is significant blood loss over a short time, symptoms may include vomiting red blood, vomiting black blood, bloody stool, or black stool. Small amounts of bleeding over a long time may cause iron-deficiency anemia resulting in feeling tired or heart-related chest pain. Other symptoms may include abdominal pain, shortness of breath, pale skin, or passing out. Sometimes in those with small amounts of bleeding no symptoms may be present.Bleeding is typically divided into two main types: upper gastrointestinal bleeding and lower gastrointestinal bleeding. Causes of upper GI bleeds include: peptic ulcer disease, esophageal varices due to liver cirrhosis and cancer, among others. Causes of lower GI bleeds include: hemorrhoids, cancer, and inflammatory bowel disease among others. Diagnosis typically begins with a medical history and physical examination, along with blood tests. Small amounts of bleeding may be detected by fecal occult blood test. Endoscopy of the lower and upper gastrointestinal tract may locate the area of bleeding. Medical imaging may be useful in cases that are not clear.Initial treatment focuses on resuscitation which may include intravenous fluids and blood transfusions. Often blood transfusions are not recommended unless the hemoglobin is less than 70 or 80 g/L. Treatment with proton pump inhibitors, octreotide, and antibiotics may be considered in certain cases. If other measures are not effective, an esophageal balloon may be attempted in those with presumed esophageal varices.
