Sonographically guided infraclavicular brachial plexus block in adults: a retrospective analysis of 1146 cases.

Objective: The aim of this study was to analyze our experience in 1146 cases of sonographically guided infraclavicular brachial plexus block (ICBPB) performed over 32 months.

Methods: Anesthetic records of 1146 cases of sonographically guided ICBPB performed by our staff were studied retrospectively with the use of a database created by an automated anesthesia record-keeping system. The rates of successful blocks, failed blocks necessitating conversion to general anesthesia or requiring supplementation with local anesthetics, those requiring larger-than-usual doses of sedation, and complications were determined.
