简要总结
The investigator will compare Costoclavicular approach of infraclavicular block and supraclavicular block. Especially, the incidence of phrenic nerve palsy and the quality of block.
详细描述
Costoclavicular brachial plexus block is a recently developed approach of infraclavicular brachial plexus block. Using ultrasound, all of 3 cords are well visible in single plane. Compared to conventional infraclavicular block, it needs smaller amount of local anesthetics.
Supraclavicular brachial plexus block is known as spinal anesthesia of upper extremities. It provides fast and good quality of anesthesia and analgesia. But some studies showed that there are over 50% of phrenic nerve palsy in supraclavicular block.
In this study, the investigator will compare phrenic nerve palsy incidence and block quality between Costoclavicular block and supraclavicular block using ultrasound.
