MEV 90 of 0.5% Ropivacaine In Infraclavicular Blocks

• Status: Unknown status
• Trial end date: 2020-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Nerve blocks are routinely performed perioperatively to provide anesthesia and analgesia for various surgical procedures on the upper limb. These blocks are performed with the aid of an ultrasound machine to improve the success rate. Below the clavicle approach to these nerves is used for surgeries below the elbow, forearm and hand efficiently.

Ultrasound guidance for such blocks allows direct visualisation of the needle and the spread of the freezing medication (local anesthetic) in real-time therefore reducing complications and improving success rates of blocks. It may be possible that a smaller volume of local anesthetic in this setting may allow effective anesthesia while lowering the adverse effects. The aim of this study is to find out the lowest volume of the local anesthetic that will be effective in blocking the nerves adequately.
