Monitoring of the Bone Free Flaps With Microdialysis

Glucose values will be recorded during 5 days as following : every hour at day 0, every 2 hours at day 1, every 3 hours at days 2 to 5.

Lactate values will be recorded during 5 days as following : every hour at day 0, every 2 hours at day 1, every 3 hours at days 2 to 5.

pyruvate values will be recorded during 5 days as following : every hour at day 0, every 2 hours at day 1, every 3 hours at days 2 to 5.

glycerol values will be recorded during 5 days as following : every hour at day 0, every 2 hours at day 1, every 3 hours at days 2 to 5.

Bone free flaps will be monitored with a microdialysis catheter directly positioned in bone tissue.
