Unilateral spinal block formation by Tachyphylaxis method

Abstract

The article presents the theoretical justification and comparative experience in the formation of a unilateral spinal block by tachyphylaxis in urgent surgery during operations on the lower extremities. The possibility of influencing the duration and severity of motor blockade on the operated side was established using the tachyphylaxis method for administering the anesthetic without decreasing the quality of anesthesia as a whole and without increasing the amount of anesthetic administered. The possibility of reducing the development time of full anesthesia to a minimum fixation time of anesthetic on nerve tissue (10 minutes) due to preliminary «sensitization» to nerve fiber anesthetics was established. The possibility of reducing the need for postoperative analgesia by increasing the duration of the postoperative painless period has been established. Keywords: unilateral spinal anesthesia, frequency-dependent blockade, motor block.
