RESEARCH OVERVIEW

Abstract

The article reviews the development and modern features of ultrasound techniques in the performance of peripheral regional blocks. As requirements steadily mount for effectiveness and safety in perioperative analgesia, this study finds relevance in efforts directed toward optimizing views of both neural structures and the needle, with lowered risks for complications to occur. The purpose is to enumerate the main physico-technical characteristics of ultrasound systems, together with improved transducer manipulation techniques, that play a role in increasing the level of accuracy and informativeness regarding peripheral blocks. The novelty of the research lies in the comprehensive comparison of linear and convex probes according to penetration depth and resolution criteria, the systematic analysis of basic transducer movements (slide, tilt, rotate, fan) and the optimal sequence of settings (depth, overall gain, TGC, dynamic range), as well as in the discussion of modern needle‑visibility enhancement technologies—from echogenic needles and beam‑steering to passive magnetic tracking and deep‑learning algorithms. Additionally, the integration of triple monitoring—ultrasound, nerve stimulator, and manometric pressure control—is proposed as a rational safety standard. The main conclusions demonstrate that selecting a probe based on nerve depth, sequentially optimizing image parameters, and employing additional technological solutions significantly enhance the nerve/fascial-plane contrast, improve needle-tip tracking, and reduce the incidence of intraneural and vascular injections. A multilevel control system ensures the timely detection of hazardous situations without prolonging procedure time, and the implementation of computer technologies opens prospects for further improvement of precision and operator training. This article will be useful to regional anesthesiologists, educators, and researchers engaged in the development and implementation of ultrasound methods in peripheral regional anesthesia.
