Risk profiles of common brachial plexus block sites: results from the net-ra registry
Main finding · Block failureResult — go to the resultAdjusted odds ratio 2.3 95% CI 1.02–5.1Authors' conclusion
The axillary approach to the brachial plexus had the highest odds for block failure and neurological dysfunction after catheter placement, as well as a significant risk for catheter failure.
