Ultrasound-guided Clavipectoral Fascial Plane Block Versus Ultrasound-guided Superficial Cervical Plexus Block in Patients Undergoing Fracture Clavicle Operation

This group includes (40) patients. The patient will be placed in a supine position with the head turned to the contralateral side for adequate exposure of the neck and the upper chest. A linear high-frequency ultrasound probe (6-13 MHz, Sonosite) will be placed at the lateral side of the neck over the midpoint of the sterno-cleido-mastoid muscle at the level of the cricoid cartilage, which corresponds with the C6 transverse process. Once the muscle is identified, the probe will then be moved posteriorly until the posterior tapering edge of the muscle is identified where the interscalene groove between the anterior and middle scalene muscles is identified. Then, the superficial cervical plexus (SCP) will be visualized. A five-cm block needle will then be introduced from lateral to medial using the posterior-in-plane technique until its tip is placed near the SCP above the prevertebral fascia.10 mL of 0.5% Bupivacaine will be deposited.

This group includes (40) patients will have medial and lateral clavipectoral (CPB) block ultrasound guided using 20 ml Bupivacaine 0.5% for medial and lateral block equally after induction of general anesthesia.

The patient will be placed in a supine position with the head turned to the contralateral side, and the shoulder will be padded with a small pillow. a 6- to 13-MHz linear array probe will be used for regional anesthesia. During CPB, an ultrasound probe will be placed on both the inner and outer one-third of the anterior surface of the clavicle. Using the in-plane technique, a 22-gauge needle will be inserted and advanced into the space between the periosteum of the clavicle and clavipectoral fascia in a caudal to cephalad direction, and a total of 20 mL of 0.5% Bupivacaine will be equally injected medially and laterally
