Details and patient eligibility

About

The purpose of this study is to compare the rate of complete sensory block at 30 minutes following ultrasound-guided single injection infraclavicular block and ultrasound-guided double injection axillary block. The investigators research hypothesis is that both blocks will show comparable rates of complete sensory block at 30 minutes.
