The Blakemore Tube

As emergency physicians, we pride ourselves on our ability to remain unfazed by a frighteningly unstable patient (a skill that most other specialties do not possess, I'll mind you), but admittedly there is that set of presentations that give even us the chills.  I'm talking about the nightmare super-necky angioedema patient that needs a cric, the peri-arrest pregnant woman who's headed toward a crash section, and the spontaneously delivered 24-week preemie who requires an umbilical artery catheter.

How's about we throw a cirrhotic with a massively-massive variceal bleed into the mix? That's a sphincter flexing sight if there has ever been one.  Let's make the scenario a bit spookier by also having no endoscopist available (unlike our tertiary teaching institution). 

Enter the Sengstaken-Blakemore Tube, basically a last ditch effort for balloon tamponade.  This procedure is not a common one given the prevalence and efficacy of endoscopy (I honestly don't even know where I'd find one in our ED), but when you're all out of options it's either this or a body bag.

First, a little clarification. There are two kinds of tubes: the Sengstaken-Blakemore Tube, and The Minnesota Tube.  For the longest time I had assumed they were one in the same but they are not.  The Blakemore Tube has 3 ports: one for gastric aspiration, one for the gastric balloon, and one for the esophageal balloon.  The Minnesota Tube is essentially the same except it has a fourth port for esophageal aspiration.

Before you even begin to insert one of these you almost certainly have to take the airway first--and with a massive bleed this alone will be far from easy.  Also, you'll need to make sure both balloons are intact per usual, and then make sure they are completely decompressed before insertion.

When it's time to pass the tube, you can do it either orally or nasally, but orally is generally preferred. Pass the tube in as far as it can go, and then hook up your aspiration port(s) to suction.  You'll need to confirm the placement with a CXR, and some have said that it makes it easier to visualize if you put 50 mL of air into the gastric balloon. Then, hook up the gastric port to a manometer (doing it with syringes will take too long), and incrementally pump it up to the total volume, which is usually about 450 mL of air (it's a freaking huge balloon, and always use air, not liquid).  After this, you'll need to clamp it, pull back until you feel resistance of the diaphragm, and secure with traction.

Start lavaging with the gastric port.  If it doesn't clear, inflate the esophageal port as well (which requires much less air, usually only 45 mL).  Clamp this one too and monitor the aspiration.  If it continues you may need more traction on your gastric port.  

Here's Scott Weingart running through the drill with the Blakemore Tube (note his patient is already tubed!).

And here's another helpful video from Yale-New Haven Hospital:

Again, this procedure is almost always a last resort, especially as it is fraught with potential complications, including esophageal rupture (why it's so important to confirm placement of that gigantic gastric balloon), mediastinitis, and aspiration pneumonia to name a few.
