Chatter causes IVC Trauma!

As we mentioned in our recent podcast Episode 8: “Prime Time!”, and as Weingart mentioned in his recent episode of the EMCRIT podcast:  Podcast 123 – Selective Aortic Arch Perfusion (SAAP) with Jim Manning, Zack and I were at UNC Chapel Hill in Jim Manning's lab doing several experiments in a pig animal model.

During one of the experiments we did a thoracotomy and what we saw was really impressive.  We all know that the ECMO lines will “chatter” when the RPM's were cranked up too high…caused by turbulence in the venous intake line when the negative pressure of the pump requests more volume than the IVC can deliver.  But I don't think any of us appreciated exactly what was happening at the IVC.

Bottom line: Chatter beats up the IVC and should really be avoided!  This video will raise your eyebrows!:

Very Cool. But who’s not wearing gloves?!? That’s old school.

i don’t mean the gloves… i mean the chatter, the flapping against the venous wall.
