MEV to Block the Posterior and Lateral Cords of the Infraclavicular Brachial Plexus — LSIB  

Anesthesia Clinical Trial

Official title:
Minimum Effective Volume (MEV95%) of Ropivacaine 7.5 mg/ml to Block the Posterior and Lateral Cords of the Infraclavicular Brachial Plexus

Clinical Trial Summary

The investigators have recently shown that LSIB in combination with a suprascapular and a cervical plexus block is a very good alternative for arthroscopic shoulder surgery. However, the investigators believe the total volume of local anesthetic for LSIB may be reduced. For shoulder surgery there is no need to block the medial cord and the investigators therefore hypothesize a significantly lower MEV95% by applying a selective lateral and posterior cord block

Clinical Trial Description

The MEV for a successful block in 50% of the participants will be determined by using the staircase up-and-down method introduced by Dixon and Massey. Logistic regression and probit transformation will be applied to estimate the MEV for a successful block in 95% of the participants. ;
