Summary
Infraclavicular brachial plexus block has been used more frequently with the development of
high-resolution ultrasound. Compared with peripheral nerve block using landmark technique or
nerve stimulator technique, ultrasound-guided peripheral nerve block decreases the required
dose of local anesthetics. As the dose of the drug used decreases, the systemic toxic effects
of local anesthetics are reduced. However, the decreased dose of the drugs might have
influence on the onset time of local anesthetics. Thus, the investigator aimed to evaluated
the onset time of the two equipotent local anesthetics, 0.375% ropivacaine and 0.25%
levobupivacaine.
