Only mucosal membranes or exposed organ regions can be treated intraoperatively with these techniques. Promising is the suggested non-contact technique for measuring the microvasculature, which is based on evaluating the local myogenic response of venules and arterioles to a cold substance. Aim of the study. Assessing the microvasculature and investigating local reserves of temperature regulation of microcirculatory in volunteers aged 20-45, stratified by gender, age, ethnicity, and existence of negative habits, using a non-contact sensor. Materials and methods. Microcirculation was assessed with a non-contact sensor at a distance of 3-5 cm from the skin on the foot, lower leg and the back of the brush. The technique consisted of continuously alternately assessing the base temperature, the temperature at the moment of supply of the refrigerant (within 30 seconds) and monitoring the rate of recovery of the base temperature. The duration of the technique (no more than 1 minute per measurement), is universal for any part of the body and is safe, because the device does not require invasive monitoring. Results. With normal blood supply, temperature recovery occurred within 2 minutes. Such data were obtained from people who did not have vascular pathology or smoke burden. A slower reaction was observed in smokers. In patients in the traumatology department, after undergoing spinal anesthesia, the line was fluctuating, and recovery of the microvasculature took longer (3 or more minutes). Conclusions. The technique of non-contact monitoring of the microvasculature response is a promising method for assessing ischemia during emergency surgery, determining the boundaries of resection of an ischemic organ, addressing the issue of tissue viability, and identifying the type of tissue based on blood supply levels in the context of cancer vigilance.</p>microcirculationmicrovasculatureischemianon-contact measurementrestoration of microcirculationмикроциркуляцияМЦРишемиябесконтактная оценкавосстановление микроциркуляции1.Козлов В.И.
