Study shows Pfat software with Sorin XTRA autotransfusion system removes fat particles during autotransfusion- LivaNova

LivaNova PLC has announced the publication of study results showing that the new “Pfat” software protocol developed for the XTRA autotransfusion system effectively eliminates lipid particles. In addition to reducing inflammatory risks by collecting, processing and re-infusing the patient's own blood shed perioperatively, Livanova’s Sorin XTRA autotransfusion system now features the new “Pfat” protocol, designed to remove fat particles from intraoperative and postoperative shed blood.

In the study titled “Fat removal during cell salvage: an optimized program for a discontinuous autotransfusion device” published on Transfusion, Seyfried et al. reported that the XTRA system incorporating the new “Pfat” protocol averaged fat removal rates higher than 99 percent using a 225 ml bowl on 10% and 25% inlet haematocrit.

In addition to XTRA’s fat removal capability, the study results confirmed that the “Pfat” protocol maintains high values for red blood cell recovery rate and supernatant elimination rate. Study researchers also found that the high fat removal rate experienced with Pfat is independent of bowl size or blood haematocrit and therefore applies to different clinical situations, including pediatric, cardiac and orthopaedic surgery.
