Podcast 721: Blakemore & Minnesota Tubes: Part II

Contributor: Dylan Luyten, MD

Educational Pearls:

  • To place a Blakemore/Minnesota Tube:
    • Insert into esophagus under visualization
    • Inflate gastric port with 60 cc of air and obtain a chest xray to ensure the balloon below the diaphragm
    • Once confirmed, place a total of 500cc of air into the gastric balloon via the gastric port
    • Tie a liter saline bad to the tube using Kerlix and hang it off an IV pole or other object to provide about 2 lbs of traction
    • Now the the tube is in place under traction, attach a manometer to the esophageal balloon port
    • Provide low pressure to tamponade a variceal bleed, which is about 33 mmHg
  • This is a temporizing measure and often patients need to get a Transjugular Intrahepatic Portosystemic Shunt (TIPS) from interventional radiology for more definitive treatment
