53b: Resuscitationist Inserted Distal Perfusion Catheter with Chris Couch

 

In this episode, we again explore the world of the distal perfusion catheter.  You heard from Joe Dubose the vascular surgeons point of view; now let's see how non-surgeon resuscitationists are dealing with this problem.  You will hear from Chris Couch, a critical care trained emergency physician from Dallas Texas and his colleague Omar Hernandez who have some novel thoughts and experiences related to when and how we insert these catheters.  You will hear about checking compartment pressures, poor man's way to “fluoro” your catheter, and much more.

53: Distal Perfusion Catheter with Joe Dubose

Episode 53 is all about the distal perfusion catheter12.  We are inserting a 15-19 Fr catheter into the femoral artery.  This limits the flow of blood to the affected extremity.  Many institutions have gone to mandatory distal perfusion catheters.  This episode is all about those catheters – when, how, which, and where.  Joe Dubose, the world reknown vascular and trauma surgeon, joins us to discuss the details of this important piece of post pump initiation.

Take Homes –

  • Common Femoral -> Superficial Femoral Artery or Posterior Tibial/Dorsalis Pedis
  • Check distal perfusion frequently
  • 5-7 Fr Catheters
  • Doppler/Temperature/Color of distal extremity
  • Remember side port of arterial ECMO catheter significantly limits the flow dynamics through the catheter
