Minimum effective concentration of bupivacaine for axillary brachial plexus block guided by ultrasound

Abstract

This study demonstrated that ultrasound guided axillary brachial plexus block can be performed with the use of low concentration of local anesthetics, increasing the safety of the procedure. Further studies should be conducted to assess blockade duration at low concentrations.

Ultrasound-Guided Block of Selective Branches of the Brachial Plexus for Vascular Access Surgery in the Forearm: A Preliminary Report

“…Because these surgeries are typically finished within a few hours (at most), and because patients usually do not experience severe pain or require long-acting postoperative analgesia, we have focused on elements of patient satisfaction including quicker onset and sufficient intraoperative effect of anesthesia as well as rapid postoperative resolution of the nerve block. Perineural injection of local anesthetic during US-guided axillary BPB has resulted in more rapid onset than perivascular injection (20), and the effective volume and concentration of local anesthetic can be reduced by perineural injection (21, 22).…”

“…In addition, the combination of two local anaesthetics (lignocaine and bupivacaine) has been found to have no added safety concerns. 7,8 Use of adjuvants has been shown to increase the duration and quality of block. The duration of blockade, extending well into the postoperative period has been frequently reported, leading to frequent addition of dexamethasone for the same purpose.…”

The Retrospective Comparison of the Effects of Low and High Volume Practices in Ultrasonography Guided Axillary Brachial Plexus Block

“…el cerrahisi yapılan hastalarda USG eşliğinde uyguladıkları aksiller blok tekniğinde %0,35'ten %0,05'e azaltmaları sonucunda konsantrasyon azaltılma-sının teknikte güvenilirliği artıracağını öngör-müşlerdir. 12 Tek ya da çok-merkezli yapılan çalışmalarda USG eşliğinde gerçekleştirilen aksiller blok uygulamalarının lokal anestetik toksisitesi ile ilişkisi saptanamamıştır. Randomize kontrollü çalışmalar USG sayesinde lokal anestezik dozunda ciddi azalma sağlanabileceğini göstermiştir.…”
