Ans:B. Sengstaken-Blakemore tube.
Sengstaken-Blakemore tube.
- It is an oro- or nasogastric tube used in the management of upper gastrointestinal haemorrhage due to bleeding from oesophageal varices.
- The gastric balloon is inflated in the stomach with 150 mls of dilute contrast for radiological confirmation of position. The inflated balloon is gently pulled up against the gastro-oesophageal junction. The oesophageal balloon is then inflated. Markings on the tubing indicate the distance from the distal end of the oesophageal balloon.
- Prolonged deployment of the balloon will lead to pressure necrosis or the rupture of the oesophagus. Releasing the oesophageal balloon at intervals should be done.
