ABSTRACT

Background: Brachial plexus infraclavicular approaches have gained popularity in recent years. Medium and coracoid infraclavicular are the one most used approaches. The placement of a catheter into the brachial plexus is not easy so the technique must ensure its correct placement. Methodology: Comparative randomized controlled clinical assay. Two groups was used: Group M: medium infraclavicular approach, and Group C: coracoid approach. The time of catheter placement, number of attempts, needle depth, anesthetic quality, and ease of installation were evaluated. Also, the placement of catheters was confirmed by plexography. Statistical method: Comparison of means, standard deviation. Results: 34 patients: 18 in Group C and 16 in Group M. The catheter was placed successfully in 72% of cases in Group C, and 2% in Group M. Installation time was 5.1 ± 1.28 minutes. Difficulty of insertion: Group C: no difficulty (27%), medium difficulty (50%), very difficult (22%), Group M, very difficult (3), impossible (13). The placement of 18 of the catheters in Group C and in 3 patients in Group M was corroborated by plexography. Conclusion: Coracoid infraclavicular is more appropriate than the medial infraclavicular approach for the placement of catheters in the brachial plexus.
