Balloon Tamponade Tubes

Balloon Tamponade Tubes

A balloon tamponade tube is a specialised tube which is inserted into the oesophagus to compress swollen blood vessels called ‘varices’. Other names for this tube include Sengstaken-Blakemore tube, a SB Tube or a Minnesota Tube.

How Does It Work?

A balloon tamponade tube is a tube similar to a nasogastric tube except it is larger, has three channels to aspirate fluid and blood through and has two balloons on the outside. When in position the tamponade tube has a long balloon (oesophageal balloon) that is positioned in the oesophagus and a round balloon (gastric balloon) at the end which is in the stomach.

A balloon tamponade tube is used when the bleeding from oesophageal varices is dangerous and the tube is usually inserted during an endoscopy.  Once in position usually only the gastric balloon is inflated to control the bleeding at the opening between the oesophagus and stomach.  You may see that the end of the tube coming out of the patient’s nose or mouth is tied to the bed or to a bag containing fluid or to some other weight. This is to keep gentle traction on the tube. This helps to keep it in the correct position and to keep the right amount of pressure on the varices.

Patients will be intubated during this period as the tube and bleeding may interfere with breathing and it is uncomfortable. Whilst the tube is in position the intensive care staff will check for bleeding by attaching large syringes to the tube.

When the gastroenterologist or surgeon feels the bleeding is under control the balloons will be deflated however the tube may stay in place for several days. 

Are There Any Complications?
