ABSTRACT
<p><b>OBJECTIVE</b>To investigate of the value of monitoring of saturation of blood oxygen of the injured extremity on prevention of osteofascial compartmental syndrome.</p><p><b>METHODS</b>Twenty patients of osteofascial compartmental syndrome included 13 male and 7 female with an average age of 32 years ranging from 13 to 60. There were 13 cases of tibial and fibual fractures, 3 cases of tibial plateau fractures, 4 cases of femoral shaft fractures. SpO2 on the end of injured extremities were dynamic monitored and osteofascial compartmental pressure was measured by modified Whiteside method. The data of two group were compared.</p><p><b>RESULTS</b>Among 20 cases, it's negative correlation between the data of pulse blood oxygen saturation and osteofascial compartmental pressure.</p><p><b>CONCLUSION</b>The method of dynamic monitor extremity SpO2 can reflect indirectly the ischemia in muscle and nerve and report the early diagnosis and management of osteofascial compartmental syndrome.</p>
