The Role of Near Infrared Spectroscopy in Diagnosing Stump Ischaemia in Patients with Below Knee Amputation: Case Reports

Functional near infrared spectroscopy (fNIRS) can be used to quantify stump oxygen saturation (SaO2) as one of many possible causes of pain following major amputation. Although commonly used for cerebral perfusion monitoring during carotid or cardiac surgery, it can also be used to monitor tissue perfusion in the lower limb and predict healing post below knee amputation (BKA). The aim of this study was to measure the SaO2 trend as there is no validated oxygen threshold to diagnose insufficient flow into the arterial collateral network currently.
