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 participants will be divided into two separate groups, the control group, Group C, and the block-applied patients, Group E. 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. After the patients to be blocked are determined by the closed envelope method, transverse protrusions will be determined from the C6 and C7 vertebral corpus levels with the help of an 8-12 mHz linear probe. With the in-plane method, the fascia placement of the needle directed between the semispinalis capitis muscle and the posterior scalene muscle in the posterior region of the transverse process will be provided and the block will be applied. During the block, a total of 20 mL volume of 0.25% bupivacaine concentration will be given bilaterally to all patients. 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.
Erector Spina Plane (ESP) block has been widely used in recent years, and it is also used in the control of postoperative analgesia in many types of surgery due to its proximity to the central area and its wide spread feature. In this study, the investigators aimed to demonstrate the effectiveness of ESP block on postoperative pain management in anterior cervical disc and fusion surgeries.
