Abstract

Objective – to assess the information content of the use of the FORE-SIGHT® MS–2000 (CASMED) tissue oximetry apparatus for measuring tissue oxygenation in various loci of the foot in normal conditions and analyzing the dynamics of the results during an occlusion test.

Material and methods. In 20 volunteers, during the occlusive vascular test, the oxygenation of the tissues of the lower extremities was assessed using the FORE-SIGHT® MS–2000 tissue oximeter, complete with pediatric and neonatal sensors. The values obtained from each sensor were recorded at all stages of the test: initial data, ischemia and reperfusion.

Results. During the use of the neonatal sensor at all stages of the test, the StO2 values were significantly higher on the dorsum of the foot, plantar surface and calf. A strong positive correlation was also found between the initial values of StO2 at the dorsum of the foot and lower leg during the use of this sensor with the age of volunteers (Spearman's coefficient R = 0.76 and 0.83, respectively, p < 0.001) and their body mass index (Spearman's coefficient R = 0.86 and 0.76, respectively, p < 0.001). However, the dynamics of changes in oxygenation values at each of the stages was higher during the use of the pediatric sensor.

Conclusion. The large dynamics of changes in StO2 values during the occlusion test and the possibility of fixing values from the deep structures of the lower extremities indicate the advisability of using a pediatric sensor in this area.
