Bloqueio do plexo braquial por via infraclavicular: abordagem ântero-posterior

Abstract

RESUMO

Bases anatômicas para o bloqueio anestésico do plexo braquial por via infraclavicular

“…Arterial puncture is reported in 50% of cases. Imbelloni et al 15 (1991) have determined that a site should be marked 1.5 cm below the point where the lateral third and two medial thirds of the clavicle meet, and this point should be 1.5 to 2 cm medial to the crycoid process. Using a neurostimulator, 50 ml lidocaine with 1.6% epinephrine are injected.…”

“…Relata punção arterial em 50% dos casos. Imbelloni e col. 15 (2001) determinam que seja marcado um ponto 1,5 cm abaixo do ponto de união entre o terço lateral e os dois terços mediais da clavícula, sendo este ponto 1,5 a 2 cm medial ao processo coracóide. Utiliza o neuroestimulador e faz a injeção de 50 ml de lidocaína com epinefrina à 1,6%.…”

Infraclavicular Topography of the Brachial Plexus Fascicles in Different Upper Limb Positions

“…According to Imbelloni et al (2001), infraclavicular block of the brachial plexus provides adequate anesthesia in cases of upper limb surgery and knowledge of the local anatomy is essential to prevent errors such as vascular punctures or complications due to pneumothorax.…”

Evaluation of brachial plexus fascicles involvement on infraclavicular block: unfixed cadaver study

“…1 The infraclavicular brachial plexus block was initially advocated by Hirschel 2 in 1913. In 1917, Bazy 3 introduced a needle below the clavicle, in a ''anesthetic line'' drawn between the anterior tubercle of the sixth cervical vertebra and the coracoid process.…”

“…In 2001, Imbelloni et al 1 determine that the injection should be at a point 1.5 cm below the site of union between the lateral third and the medial two-thirds of the clavicle, succeeding in 94% of cases.…”
