A Sengstaken–Blakemore tube is a medical device inserted through the nose or mouth and used occasionally in the management of upper gastrointestinal hemorrhage due to esophageal varices (distended and fragile veins in the esophageal wall, usually a result of cirrhosis).
Sengstaken–Blakemore tube, with three lumens (two balloons and a gastric aspiration port). Pressure can be applied to gastric and esophageal varices by balloon inflation and traction. [1] Linton tube, with a large gastric balloon, and gastric and esophageal aspirates
An open (differential) mercury pressure gauge. A mercury pressure gauge is a type of manometer using mercury as the working fluid. The most basic form of this instrument is a U-shaped glass tube filled with mercury. More complex versions deal with very high pressure or have better means of filling with mercury.
In cases of refractory bleeding, balloon tamponade with a Sengstaken–Blakemore tube may be necessary, or the use of a fully-covered esophageal self-expandable metallic stent, usually as a bridge to further endoscopy or treatment of the underlying cause of bleeding (i.e.: portal hypertension).
Anorectal manometry (ARM) is a medical test used to measure pressures in the anus and rectum and to assess their function. [1] [2] The test is performed by inserting a catheter, that contains a probe embedded with pressure sensors, through the anus and into the rectum. [3]
A Sengstaken-Blakemore tube will not be able to stop bleeding as here the bleeding is arterial and the pressure in the balloon is not sufficient to overcome the arterial pressure. After patient receives appropriate intervention, bleeding must be observed for at least 48 hours as a follow-up. [10]
1. Plan Ahead. Start by mapping out your meals for the week. A helpful way to do this is to look at your calendar. This tells you what you have going on, whether it’s evening business meetings ...
High-resolution manometry (HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors. For a manometry system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most 1 ...
