How to perform a haemodialysis using the arterial and venous lines of an extracorporeal life support

Résumé fourni par la source

Continuous renal replacement therapy is particularly suited in the setting of acute renal failure, occurring after cardiac surgery, in patients requiring extracorporeal life support (ECLS) or membrane oxygenation. In such patients, temporary catheters are not necessary since the circuit of haemodialysis or haemofiltration may be connected on the ECLS cannulae. We report how to modify a classical ECLS circuit to connect directly the haemodialysis (Prismaflex device, Gambro-Hospal, Lyon, France) to the ECLS. We also detail parameters used to initiate the haemodialysis. Actually, we modify all our ECLS circuits as described here, at implantation time, allowing rapid haemodialysis initiations. Since 2004, 21 patients have been treated, as described here, without supplemental mortality or related complication.
