Summary

This is a prospective, single arm, open, single centre clinical investigation designed to examine the feasibility and safety of the IscAlert™ device in patients scheduled for limb (arm/leg) surgery with tourniquet. IscAlert is measuring carbon dioxide in muscular and subcutaneous tissue. IscAlert is inserted into normal muscle and subcutaneous tissue in ischemic (operated limb with a tourniquet) and non-ischemic limb (non-operated limb).After the tourniquet is inflated, ischemia develops in the muscles and subcutaneous tissue. This will result in an increase in carbon dioxide, which will be detected by the sensor on the operated extremity, while the sensor on the non-operated will show normal values. After releasing the tourniquet cuff, the muscle will be reperfused and the carbon dioxide level is expected to decrease into normal levels. 50 number of patients will be enrolled to undergo the procedures. The IscAlert will be removed from the patient before the patient is discharged from the operating room, but in 25 of the patients, IscAlert™ will be inserted for 72 hours in the operated extremity after the end of surgery. After this, the sensors are removed.250 Devices is planned to be used in this clinical study.
