Ultrasound-Guided Intermediate Cervical Plexus or Cervical Erector Spinae Block for Anterior Cervical Spine Surgery

Regional Analgesia Using Ultrasound-Guided Intermediate Cervical Plexus Block or Cervical Erector Spinae Block for Anterior Cervical Spine Surgery: A Randomized Trial

• Neck pain and stiffness or sore throat, are common after anterior cervical spine surgery. Complications are rare but can be serious and even potentially life-threatening if they do occur. Rapid recovery and emergence from general anesthesia are important in cases of anterior cervical spine surgery.

• Null hypothesis (H0): No difference between the regional analgesia effects of bilateral ultrasound-guided superficial cervical plexus block and bilateral cervical erector spinae block in patients undergoing anterior cervical spine surgery under general anesthesia.
• Alternative hypothesis (H1): There are differences between the regional analgesia effects of bilateral ultrasound-guided superficial cervical plexus block and bilateral cervical erector spinae block in
