High-Resolution Three-Dimensional Imaging of the Footpad Vasculature in a Murine Hindlimb Gangrene Model
Published on: March 16, 2022
Abstract:
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.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
