- Brief Summary
Major spine surgery with multilevel instrumentation is followed by a large amount of opioid consumption, significant pain, and difficult mobilization Pain is one of the main factors limiting ambulation, increasing the risk of thromboembolism by immobility, and causing metabolic changes that affect other systems. Therefore, individualized pain management with the use of appropriate analgesic techniques is of paramount importance. Moreover, early intervention in rehabilitation aiming at a better postoperative recovery may reduce the length of hospital stay and return to daily activity. Effective pain management is one of the crucial components in enhanced recovery after surgery (ERAS).
Numerous regional anesthetic techniques have been used to provide analgesia following cervical spine surgery, including patient-controlled epidural analgesia, cervical paravertebral block, cervical plexus block, cervical erector spinae plane blocks, and local infiltration analgesia, however, each of these techniques has specific limitations that prevent them from being the analgesic technique of choice for such surgeries.
Up to the author's knowledge, there is no study done to compare multifidus cervicis plane block versus inter-semispinal plane block in a randomized controlled clinical trial as preemptive analgesia in patients undergoing cervical spine surgery.
- Detailed Description
Spine surgeries are commonly associated with severe postoperative pain, particularly complex procedures such as laminectomy on more than two disc levels, or scoliosis surgery, especially on the first postoperative day. Spinal foraminal stenosis and disc herniation, occurring often around C5-C7 levels, are the most popular underlying pathologies of the cervical spine.
One of the keys to a patient's recovery following cervical spine surgery is effective postoperative pain management. Nowadays, the concept of pain management with multimodal analgesia and regional anesthesia plays a crucial role in postoperative analgesia reducing opioid consumption and improving early mobilization. Numerous regional anesthetic techniques have been used, including patient-controlled epidural analgesia, cervical paravertebral block, cervical plexus block, cervical erector spinae plane blocks, and local infiltration analgesia. However, some of these techniques have specific limitations that prevent them from being the analgesic technique of choice for cervical spine surgery, and the others are still under research for its effectiveness.
Several new paraspinal blocks have been described in the thoracic and lumbar regions in which the dorsal rami of cervical nerves can be blocked without the block needle entering the paravertebral space. Moreover, novel cervical region blocks, including cervical interfascial plane (CIP) block, multifidus cervicis plane block (MCP), inter-semispinal plane (ISP) block, and retrolaminar cervical block have been developed. All these interfascial plane blocks are considered as promising alternatives to neuraxial blockade for various surgeries.
Multifidus cervicis plane (MCP) block First described by Ohgoshi et al. as a case report for analgesia after cervical laminoplasty, where the local anesthetic was injected between the multifidus cervicis and semispinalis cervicis muscles fascial planes at C5 level. Furthermore, MCP block was effective in another study as a treatment for cervicogenic headaches.
The inter-semispinal plane (ISP) block is also described by Ohgoshi et al., by injecting local anesthetic into the fascial plane between the semispinalis cervicis and capitis muscles and it effectively blocked multiple dorsal rami of the cervical spinal nerves in healthy volunteers.
This study will be designed for evaluation and comparison between Multifidus cervicis and inter-semispinal plane blocks as pre-emptive analgesia for patients undergoing cervical spine surgery under general anesthesia.
