Minnesota four-lumen tube, with esophageal and gastric balloons, and esophageal and gastric aspirates. Balloon tamponade is considered a bridge to more definitive treatment modalities, and is usually administered in the emergency department or in the intensive-care unit setting, due to the illness of patients and the complications of the procedure.
Gastric aspiration and or lavage, where a tube is inserted into the stomach via the nose in an attempt to determine if there is blood in the stomach, if negative does not rule out an upper GI bleed [20] but if positive is useful for ruling one in. [14] Clots in the stool indicate a lower GI source while melana stools an upper one.

A nasogastric aspirate can help determine the location (source) of bleeding and help understand the best initial diagnostic and treatment plan. Nasogastric aspirate has a sensitivity of 42%, specificity 91%, negative predictive value 64%, positive predictive value 92% and overall accuracy of 66% in differentiating upper gastrointestinal ...
This avails for aspiration in one lumen, and venting in the other to reduce negative pressure and prevent gastric mucosa from being drawn into the catheter. [5] Dobhoff tube, which is a small bore NG tube with a weight at the end intended to pull it by gravity during insertion. The name "Dobhoff" refers to its inventors, surgeons Dr. Robert ...
Gastritis is the inflammation of the lining of the stomach. [1] It may occur as a short episode or may be of a long duration. [1] There may be no symptoms but, when symptoms are present, the most common is upper abdominal pain (see dyspepsia). [1]
A prime example of this is pepsin, which is secreted in the stomach by chief cells. Pepsin in its secreted form is inactive . However, once it reaches the gastric lumen it becomes activated into pepsin by the high H+ concentration, becoming an enzyme vital to digestion. The release of the enzymes is regulated by neural, hormonal, or paracrine ...
