Efficacy of Cervical Erector Spina Plane Block and Superficial Cervical Plexus Block in Anterior Cervical Disc and Fusion Surgery

This study includes ASA I-II patients aged 18-65 years who will undergo Anterior Cervical Disc and Fusion Surgery at C5 or C6 level under general anesthesia under elective conditions. In the preoperative period, the participant groups will be divided into two separate groups, Group cESP and Group sCPB, according to the type of block applied.

Groups will be compared according to demographic data, duration of surgery, perioperative drug consumption, postoperative pain scores, additional analgesic requirement and presence of shoulder pain. The blocks will be applied with the help of an 8-12 mHz linear probe after the patients are determined by the closed envelope method. In group cESP, block will be applied using in-plane technique at the level of C6 or C7 transverse vertebral corpus in the fascia between the semispinalis capitis muscle and the posterior scalene muscle. During the block, a total of 20 mL volume of 0.25% bupivacaine concentration will be given bilaterally to all patients. Group sCPB will be administered using 10 mL of 0.25% bupivacaine by entering from the C4 level from the right side of the neck from the posterior side of the sternocleidomastoid muscle. It was planned to routinely administer 10 mg/kg paracetamol and 2x10 mg tenoxicam iv to all patients for postoperative pain control. Patients will be taken to the recovery unit in the postoperative period, where their analgesic needs, frequency of nausea-vomiting, VAS scores, and additional problems will be followed up by the nurse who was included in the study blindly. After 1 hour of follow-up in the Recovery Unit, the participants will be directed to the service. The participants' VAS scores and additional analgesic needs will be recorded at 6, 12, and 24 hours postoperatively.
