Primary outcomePrimary: Number of Patients With Complete Sensory Block — 91; 79 percentage of participants — p=<0.01
Summary
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.
