Brief Summary:

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.


Condition or disease Intervention/treatment Phase
Human Volunteers Device: Tourniquet Device: INVOS assessment Device: EMG assessment Phase 1

Detailed Description:
After inflation of a tourniquet (pressure equal to the mean arterial pressure, we will obtain a model of slight venous congestion and arterial hypoperfusion. A comparison will be made between INVOS monitoring, sensory deficits, pain, electromyography and invasive pressure.

Arm Intervention/treatment
Experimental: Tourniquet
Inflation of a tourniquet

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Comparison Between INVOS Monitoring and Electromyography [ Time Frame: 45 minutes ]

    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.

    Measures were:

    [mean (SD)] INVOS (in %) value at baseline and at the time of the block


  2. Intracompartmental Pressure (ICP) [ Time Frame: 45 minutes ]
    [mean (SD)] ICP (in mmHg), value at baseline and at the time of the block
