In Patients Under Extracorporeal Co2 Removal Therapy (ECCO2R) For Ards Can We Do Prone Position? Efficiency, Stability and Safety of the Maneuver

Methods In our intensive care unit of 15 beds with a large experience of PP, we have retrospectively included all sessions of PP (at least 16 hours of PP) performed on patients under ECCO2R therapy between august 2014 and march.2015. We used ILA ACTIVVE device (NOVALUNG) with MINILUNG membrane and a double line femoral catheter (NOVAPORT TWIN 24F). The gas flow was 10l/ min. For each session we compared PaO2/FiO2 and the PaCO2 before and after 1H of PP. For each session, we did the mean of blood flow and drainage pressure (P1) during a length of one hour : during the last hour before PP, the first hour after PP and the last hour before stopping PP. We compared with a Friedman’s test, the mean and the coefficient of variation of each parameter to evaluate the stability of the device. We noted all the side effects of the PP (bleeding, decanulation, etc.).
