Summary
Systemic LA toxicity is an important complication of regional anesthesia. Lowering the LA
dose is one of the strategies to reduce this risk. For upper limb blocks it is well
documented that ultrasound guidance allows a significant lower dose of LA for interscalene
and axillary blocks than with guidance by peripheral nerve stimulation. However, a
corresponding difference has not yet been found for supraclavicular and infraclavicular
blocks. The aim of the present study is to define the minimum effective volume of ropivacaine
7.5 mg/ml when using the LSIB method.
