MEV for Retroclavicular Approach to Infraclavicular Block

Status Terminated

Clinical Trial Summary

In this study, the primary objective was to estimate the minimum effective volume of bupivacaine 0.5% resulting in successful block in 90% of patients (MEV90) for ultrasound-guided retroclavicular approach to infraclavicular brachial plexus block.

Clinical Trial Description

A "biased coin up-and-down sequential design" will be applied to assess the minimum effective volume in 90% of patients for the retroclavicular brachial plexus block. The first subject received 25 ml 0.5% bupivacaine . Each subsequent patient received a dose that depended on the response of the previous one. If the previous block is successful, the block will be performed either by a reduction of the volume by 2.5 ml with a probability ß = 0.11 or by a same dose of the previous one with a probability 1-ß = 0.89 in the next patient. ;
