Monitoring of the Bone Free Flaps With Microdialysis
Sponsor: Centre Hospitalier Universitaire, Amiens
Summary
Microdialysis is admitted to be reliable by numerous surgeons to monitor flaps. Nevertheless, a few authors reported follow up with microdialysis in bone free flaps, and they all describe the position of the catheter in the surrounding soft tissue muscle which is not the accurate reflect of bone vascularisation. The aim of this study is to determine the lactate/pyruvate ratio mean value in bone free flaps with a microdialysis catheter directly positioned in the bone tissue.
