Transcutaneous oxymetry as a useful diagnostics method of microcirculation in diabetic patients

Abstract

BACKGROUND. The aim of this study was to compare transcutaneous parcial oxygenation (tcpO₂) and tcpCO₂ between diabetic patients type 2 and healthy patients by using transcutaneous oxymetry. The aim was also to asses this diagnostic method in shorttime diabetic patients.
MATERIAL AND METHODS. There were examined 61 patients in which ankle-brachial index were normal: 0.9 > ABI < 1.3. The diabetic group consisted of 31 patients. The control group consisted of 30 healthy patients without cardiovascular disorders, age and gender - matched to diabetic group. The average duration of diabetes was 2.9 years ± 1.8 SD. There were examined both foot; left then right, using oxymetry’s electrode, which it was ever calibrated and term to 43°C. TcpO₂ and tcpCO2 was assessed after stabilization of the curves.
RESULTS. We do not observed significantly differences between left and right lower limb in both examined groups. We observed decrease tcpO₂ (55.4 ± 7.94) in diabetic patients compared with control group (58.9 ± 7.74). There were marked also high correlation between lower limbs over tcpO₂ and tcpCO₂ parameters.
CONCLUSIONS. Oxymetry research was shown decreased tcpO₂, what can preced appear later structural disorder of microcirculation. Transcutaneous oxymetry is valuable attachment vascular diagnostic apply to tcpO₂.
