Main sonographic parameters of regional anesthesia conduction in the lower extremities under ultrasound guidance

: The purpose of this research is to study the main sonographic parameters of nerve and needles, as well as some methodological aspects of regional anesthesia under ultrasound control, comparing the results of different methods, approaches to the performance of lower limbs regional anesthesia under ultrasound guidance, the formulation of general principles for optimization of visual identification of the needle, catheter during anesthesia with the definition of localization, structure and distribution of entered anesthetic. The ultrasound is an effective method of control of the lower extremities regional anesthesia. The further study and improvement of methodological aspects is required. With the proposed method is possible to conduct qualitative sonographic navigation with high efficiency in all patients.
