Comparing Local Anesthetic Techniques for Clavicular Surgeries

The patient will receive selective supraclavicular nerve block, then will undergo blockage of superior trunk "the fifth and sixth cervical nerves" of the brachial plexus. The operator will scan the supraclavicular nerve on the lateral border of the sternomastoid muscle. Local anesthetics mixture"3 cc" will be injected in 0.5 cc aliquots after negative aspiration to encircle the supraclavicular nerve. Then ultrasound probe will be moved to scan the superior trunk "the fifth and sixth cervical nerves" in the scalene groove.15 cc of local anesthetics mixture will be injected in 0.5 cc aliquots to encircle the fifth \& sixth cervical nerve roots.

The patient will receive selective supraclavicular nerve block, then will undergo clavipectoral fascial plane block. The operator will scan the supraclavicular nerve on the lateral border of the sternomastoid muscle. Local anesthetics mixture"3 cc" will be injected in 0.5 cc aliquots after negative aspiration to encircle the supraclavicular nerve. The ultrasound probe will scan both the medial \& lateral ends of the clavicle. Then Local anesthetics mixture"15 cc" will be injected in 0.5 cc aliquots after negative aspiration between the periosteum of the clavicle and the clavipectoral fascia. The same technique will be conducted on both the lateral and medial ends of the affected clavicle.
