About

Posterior cervical spine surgery often requires a large posterior midline incision, resulting in poorly controlled postoperative pain, which arises from iatrogenic mechanical damage, intraoperative retraction, and resection to structures such as bone, ligaments, muscles, intervertebral discs, and zygapophysial joints.

Full description

Ultrasound-guided Inter-semispinal plane (ISP) block, was proposed as a novel technique for analgesia in posterior cervical spine surgeries. The ISP block involves an injection of local anesthetic into the fascial plane between the semispinalis cervicis and semispinal capitis muscles and results in blocking the dorsal rami of the cervical spinal nerves. ISP block can provide effective analgesia in posterior cervical spine surgery

52 participants in 2 patient groups, including a placebo group

The block group (ISP)

Active Comparator group

Description:

After aseptic preparation of the injection area, the needle will be introduced in-plane through the skin and advanced into the fascial plane between the semispinalis cervicis and semispinalis capitis muscles. After negative aspiration for blood, 20 ml of 0.25% bupivacaine on each side will be injected for each block.

Treatment:

Procedure: Inter-semispinal plane block

Placebo Comparator group

Description:

No block will be performed
