ICU "news":

Have you heard about the Doraya catheter? It is percutaneously deployed in the IVC below the level of the renal veins & works as a temporary iv flow regulator -> partially obstructing the venous flow -> ⬇️ cardiac preload & venous congestion

In a very small preliminary study, the catheter was placed in 9 patients (LVEF 24±12%) for a mean duration of 8.5 hours. The catheter deployment led to significant pressure ⬇️ above the device 12.4±4.7 mmHg, when compared to unchanged pressure below the catheter 18.5±6.2 mmHg

Diuresis was 77.1±25 ml/h at baseline, and 200.8±93 ml/h during device deployment with average peak urine output of 294 ± 139 ml/h... Spot urine Na increased from 35 to 101 mmol/l

Obviously, I have no COI... But I will dare to say that it's quite possible that intravascular procedures/interventions will be the next big thing in Critical Care. Just think about ECPR/Impella/REBOA/Doraya/Flowtriever etc.

Let's see what the future holds... I hope that we will not be disappointed once again!

Thanks for reading!
