In Vivo Optical Spectroscopy Monitoring in a New Model of Muscular Compartment Syndrome
Muscular compartment syndrome (MCS) is consecutive to an increase in intramuscular compartment pressures, and is a rare but serious postoperative complication.
The INVOS (In Vivo Optical Spectroscopy) monitors tissular oxygenation continuously and non-invasively.
The objective is to develop a model mimicking the physiopathology of MCS to assess the interest of the INVOS in this case.

- Comparison Between INVOS Monitoring and Electromyography [ Time Frame: 45 minutes ] [ Designated as safety issue: Yes ]
A comparison will be made between the INVOS monitoring and non invasive (transcutaneous) EMG monitoring (AP Block), to determine the accuracy of the INVOS monitoring to predict AP block.
