Postoperative Analgesic Efficacy of SPSIPB in Anterior Cervical Discectomy

February 23, 2026 updated by: Oguz Gundogdu, Cumhuriyet University

Effects of the Serratus Posterior Superior Intercostal Plane Block on Postoperative Pain Levels and Analgesic Requirement in Patients Undergoing Cervical Disc Herniation Surgery

Anterior cervical discectomy is an operation performed for complaints of pain, numbness or loss of strength due to cervical disc disease. With this operation, pressure due to herniation on the upper neck area, spinal cord or nerve roots is relieved. It is performed by microscopic method from the front of the neck.

Nerve blocks reduces opioid consumption in the postoperative period by providing better pain control and therefore has advantages such as fewer side effects and less risk of pulmonary and cardiac complications.

In this study; it was aimed to compare the analgesic effectiveness of serratus posterior superior intercostal plane block and erector spinae plane block, and with the control group in the postoperative period in patients who underwent anterior cervical discectomy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Group without peripheral nerve block
After the patients are monitored, they will be operated under general anesthesia without peripheral nerve block and intraoperative intravenous analgesics (dexketoprofen 50 mg, paracetamol) will be given.
Procedure: The group treated with intravenous analgesics
In the postoperative period a ibuprofen dose of 400 mg every 8 hours were administered iv for multimodal analgesia
Active Comparator: Serratus posterior superior intercostal plane block

In this study, the intervention will be the SPSIPB. The block will be performed with the patient in the lateral decubitus position.A high-frequency (7-12 MHz) linear transducer will be placed in the transverse plane at the level of the spina scapulae, and the superior medial border of the scapula, the trapezius muscle, the rhomboid muscle, the serratus posterior superior muscle (SPSM), and the second and third ribs will be visualized.

Subsequently, a sonovisible needle will be advanced just medial to the scapula, targeting the area between the second and third ribs to reach the fascial plane between the SPSM and the intercostal muscles. After the needle makes gentle contact with the rib, 1-2 mL of saline will be used to confirm the correct plane. A total of 30 mL of 0.25% bupivacaine will then be administered into this fascial plane between the SPSM and the intercostal muscle.In the intraoperative period, intravenous analgesics (dexketoprofen 50 mg, paracetamol 1000 mg) will be given.
Procedure: Serratus posterior superior intercostal plane block
Serratus posterior superior intercostal plane block will be performed on the patients using 30 ml of 0.25% bupivacaine under ultrasound guidance.Additionally, in the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Numeric Rating Scale (NRS) Scores
Time Frame: Postoperative 24 hours
Numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.
Postoperative 24 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Quality of Recovery scores
Time Frame: Postoperative 24 hours
Quality of recovery-15 (QoR15) scale was used for the assessment of patients satisfaction. The scores of QoR15 changes between 0 to 150 points. 0 point means "there is no satisfaction." Higher scores mean indicating a good quality of recovery and better outcome.
Postoperative 24 hours
Total tramadol consumption
Time Frame: Postoperative 24 hours
Postoperative total analgesic need was recorded as "milligram" in unit.
Postoperative 24 hours
