Answer
1)Minnesota tube or modified Sengstenken Blackmore tube.
** Original Sengstenken Blackmore tube only has three lumen (no esophageal aspiration)
2)To control esophageal variceal bleeding.
3)Ischemic necrosis of esophageal mucosa, aspiration pneumonia.
4)How to inflate the balloon
Esophageal balloon: Connect to the BP set and inflate with pressure 30-40mmHg
Gastric balloon: Inflate with 200 ml water for injection (give approximately 60 mmHg pressure)
Notes
-Deflate esophageal balloon 8 minutes every 5 hours (reduce risk for esophageal necrosis)
-Reduce pressure in esophageal balloon to 25mmHg by 12 hours
-Do not left the tube for more than 24 hours.
Where to find the tube?
Usually it is being kept in refrigerator so that it will become more rigid and easily to introduced.
Function of each lumen
Esophageal balloon: inflate esophageal balloon
Esophageal aspiration: aspirate saliva and prevent aspiration pneumonia
Gastric balloon: inflate gastric balloon
Gastric aspiration: decompress the stomach content
