Assessment of ischaemic feet in diabetes.
Transcutaneous oximetry, laser Doppler flowmetry and ankle brachial systolic pressure indices were used to investigate blood flow to the feet in 26 subjects with diabetes mellitus and peripheral arterial disease. A total of 21 critically ischaemic feet and 15 non-critically ischaemic feet were investigated. Using laser Doppler flowmetry, non-critically ischaemic feet demonstrated a significant increase in maximum blood flow, and percentage increase in flow following local heating (p = 0.038, p = 0.012) in comparison with critically ischaemic feet. These statistically significant differences reflect an increased hyperaemic response in non-critically ischaemic feet.
