Spinal foraminal stenosis and disc herniation, occurring often around C5-C7 levels, are the most popular underlying pathologies of the cervical spine.\n\nOne 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.\n\nSeveral 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.\n\nMultifidus 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.\n\nThe 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.\n\nThis 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.",[36,42,48],{"label":37,"type":38,"description":39,"interventionNames":40},"control group","PLACEBO_COMPARATOR","patients will be operated under general anesthesia",[41],"Procedure: control group",{"label":43,"type":44,"description":45,"interventionNames":46},"MCP group","ACTIVE_COMPARATOR","patients will receive MCP block followed by general anesthesia",[47],"Procedure: MCP group",{"label":49,"type":44,"description":50,"interventionNames":51},"ISP group","patients will receive ISP block followed by general anesthesia",[52],"Procedure: ISP group",[54,57,60],{"type":55,"name":37,"description":39,"armGroupLabels":56,"otherNames":21},"PROCEDURE",[37],{"type":55,"name":43,"description":58,"armGroupLabels":59,"otherNames":21},"patients will receive ultrasound-guided MCP block with 15 ml of bupivacaine 0.25% on each side followed by general anesthesia.",[43],{"type":55,"name":49,"description":61,"armGroupLabels":62,"otherNames":21},"patients will receive ultrasound-guided ISP block with 15 ml of bupivacaine 0.25% on each side followed by general anesthesia.",[49],[64],{"name":65,"affiliation":66,"role":67},"Shereen E Abd Ellatif, MD","Faculty of medicine, zagazig university","PRINCIPAL_INVESTIGATOR",[69],{"name":65,"role":70,"phone":71,"phoneExt":72,"email":73},"CONTACT","+20552336654","002","shosh.again@gmail.com",[75],{"facility":66,"status":76,"city":77,"state":78,"zip":79,"country":80,"countryCode":81,"cosmosGeoPoint":82,"geoPoint":87,"contacts":88},"RECRUITING","Zagazig","Alsharqia","4115","Egypt","EG",{"type":83,"coordinates":84},"Point",[85,86],31.502,30.58768,{"lat":86,"lon":85},[89,90],{"name":65,"role":70,"phone":71,"phoneExt":72,"email":73},{"name":65,"role":67,"phone":21,"phoneExt":21,"email":21},{"type":67,"investigatorFullName":92,"investigatorTitle":93,"investigatorAffiliation":5,"oldNameTitle":21,"oldOrganization":21},"Shereen Elsayed Abd Ellatif","associate professor of anesthesia and surgical intensive care","100522490",false,"NCT06083298","Multifidus Cervicis and Inter-Semispinal Plane Blocks in Analgesia After Cervical Spine Surgery","Comparison Between Multifidus Cervicis and Inter-semispinal Plane Blocks in Analgesia After Cervical Spine Surgery: A Randomized Controlled Trial","Inclusion Criteria:\n\n* Patient acceptance.\n\n  * Age 21-60 years old.\n  * BMI ≤ 30 kg\u002Fm2\n  * ASA I - II.\n  * Elective posterior cervical spine surgery under general anesthesia.\n\nExclusion Criteria:\n\n* History of allergy to the LA agents used in this study\n\n  * Skin lesion at the needle insertion site,\n  * Those with bleeding disorders, sepsis, liver disease, and psychiatric disorders\n  * History of chronic pain and taking analgesics\n  * History of cognitive dysfunction or mental illness","ALL","21 Years","60 Years",{"count":104,"type":105},105,"ESTIMATED","INTERVENTIONAL",[108],"NA","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.

Moreover, early intervention in rehabilitation aiming at a better postoperative recovery may reduce the length of hospital stay and return to daily activity.
