A new review summarized published adverse effects when IV lipid emulsion is used along with venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with cardiotoxic drug poisoning.
Not surprisingly, running fat through the ECMO circuit can cause some issues. Here's what's been published:
cracking of stopcocks
fat emulsion agglutination
clogging and associated malfunction of the membrane oxygenator
increased blood clot formation in the circuit
It's unclear how these findings should change management if using both treatment modalities, but at the very least, be aware that fat depostion in the VA-ECMO circuits and increased blood clot formation can occur.
