Description
Oesophageal varices commonly develop in the setting of portal hypertension. A Sengstaken-Blakemore (SB) tube is sometimes emergently required to control oesophageal bleeding.12
The normal portal pressure varies from 5 to 10 mm Hg. Portal hypertension occurs when the portal pressure rises above 10 mm Hg. Pressures can rise up to 30 mm Hg, so the pressure exerted and maintained on the oesophageal balloon to tamponade the varices will need to be above 30 mm Hg.
The current practice is to attach a 1 L bag of saline to the tube to maintain traction. However, there are risks associated with this method of traction. These risks include pharyngeal ulcers and mouth ulcers from the local pressure effect. We describe an alternative method of maintaining traction on the SB tube.
We describe the practice of securing the tube with a pair of wooden tongue depressors and padding as shown in figure...
