Conditions
Summary
Perpheral nerve blocks are known to induce many changes in the local circulation such as vasodilation. We use the ultrasound-doppler to show and quantify the variations of the regional hemodynamics of the upper arm after an infraclavicular brachial plexus block.

Exclusion Criteria5
- Patient refusal
- Allergy to local anesthetics
- Existing neurological disorders, neuropathy of the operative extremity
- Infection at site of needle puncture
- Coagulation disorders
