Muscular compartment syndrome and in vivo optical spectroscopy monitoring: a new model
KeywordsMean Arterial Pressure Optical Spectroscopy Compartment Syndrome Conduction Block Sensory Deficit
The muscular compartment syndrome (MCS) is consecutive to an increase in intramuscular compartment pressures .This is a rare but serious postoperative complication. In vivo optical spectroscopy (INVOS) monitors tissular oxygenation continuously and non-invasively. Our objective was to develop a model mimicking the physiopathology of MCS and to assess the interest of the INVOS in this case [1, 2, 3].
After approval of the ethics committee, we inflated a tourniquet in nine healthy volunteers at a pressure equal to the mean arterial pressure (MAP), obtaining a model of slight venous congestion and arterial hypoperfusion. The INVOS monitoring was compared with sensory deficits, pain, motor activity, electromyography and invasive pressure.
