METHOD OF INTERSCALENE BLOCKADE OF BRACHIAL PLEXUS IN SECONDARY LYMPHOSTASIS OF UPPER EXTREMITY AFTER RADICAL MASTECTOMY Russian patent published in 2020 - IPC A61M19/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to anesthesiology, and can be used for interscalene blockade of brachial plexus in secondary lymphostasis of upper extremity following radical mastectomy. That is ensured by ultrasonic visualization of brachial plexus with a high-frequency sensor and introduction of a neurostimulation needle lateral to an ultrasonic sensor in its scanning plane. For accurate positioning of the needle, electric stimulation of the nerve bundle with an initial current intensity of 1 mA, frequency of 1 Hz and duration of 0.1 ms is used. After positive response to stimulation, current intensity is reduced to minimum threshold of response to stimulation of 0.7 mA. A neuropesticular needle is introduced with 0.75% ropivacaine solution 5 ml to each of the imaged plexus trunks.

EFFECT: invention enables reducing manipulation injuries and providing higher postoperative analgesia efficiency.
