Overview

Brief 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.

Outcomes

Primary Outcomes

Number of Patients With Complete Sensory Block

Time Frame: 30 minutes after block completion

Complete sensory block is defined by anesthesia to cold sensation in the ulnar, radial, median and musculocutaneous nerves territories.

Secondary Outcomes

Number of Patients With Complete Motor Blocks(30 minutes after block completion)
Time to Complete Sensory Block.(5, 10, 15, 20, 25 and 30 minutes after block completion)
Time to Complete Motor Block(5, 10, 15, 20, 25 and 30 minutes after block completion)
Surgical Block Success Rate(End of surgery)
Performance Time of the Nerve Block(During the performance of the block)
Duration of Surgery(The end of surgery)
Tourniquet Use(The end of surgery)
Duration of Tourniquet(The end of surgery)
