Overview
Brief Summary
The investigators compared the postoperative analgesia of nerve stimulator-guided and ultrasound-guided infraclavicular block for upper extremity surgery.
Detailed Description
Ultrasound (US)-guided peripheral nerve block has increased in popularity. It has many advantages such as improved success rate, faster onset time, fewer needle passes, shorter performance time, and reduced procedural pain and vascular puncture. However, there is no information about postoperative analgesia. Therefore, the investigators tested whether ultrasound-guided peripheral nerve block enhanced the postoperative analgesia for upper extremity surgery compared with nerve stimulator (NS) guidance.
