Effect of Superficial Cervical Plexus Block on the Postoperative Quality of Recovery (QoR)

Pain and discomfort after anterior cervical spine surgery is difficult to quantify and quoted as moderate in severity, often needing oral opioid analgesics. In addition, these patients are more prone for postoperative respiratory complication due to airway edema secondary to surgical retraction or wound hematoma. Opioid analgesics provide good pain control but postoperative nausea and vomiting and respiratory depression are undesirable in these patients who are at risk for postoperative wound hematoma and airway edema The use of multimodal analgesia is rapidly becoming the 'standard of care' for preventing pain after ambulatory procedures at most surgery centers throughout the world . The purpose of this study is to determine whether superficial cervical plexus block will improve the postoperative quality of recovery as measured by Quality of Recovery 40 questionnaire (QoR-40) in patients undergoing elective anterior cervical discectomy and fusion.

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:
  • The primary outcome measure is the global QoR-40 aggregate score after ACDF surgery. [ Time Frame: 24 hours ]

Secondary Outcome Measures:
  • post operative pain score assessment [ Time Frame: 24 hours ]
  • Post operative analgesic consumption [ Time Frame: 24 hours ]
  • time for the first dose of opioid consumption [ Time Frame: 24 hrs ]
  • post operative nausea and vomiting [ Time Frame: 24 hrs ]
  • post operative sedation score [ Time Frame: 24 hrs ]

Enrollment: 46
Study Start Date: August 2012
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: superficial cervical plexus block
superficial cervical plexus block for experimental group
Other: Superficial cervical plexus block for experimental group
15 ml of 0.25% Bupivacaine will be given for superficial cervical plexus block
No Intervention: No Block
no superficial cervical plexus block for the no intervention group

Detailed Description:

Anterior cervical discectomy and fusion is increasingly being done as a day surgery or short stay surgery. Postoperative pain is the leading cause of unplanned hospital admissions following day surgery, a major source of dissatisfaction and often impairs the quality of recovery. Opioid analgesics alone are not always effective and may also worsen the postoperative nausea and vomiting and in turn the postoperative recovery. This study is designed to find out if an injection of freezing on the side of neck around the nerves (superficial cervical plexus block) improves the quality of recovery from anesthesia and surgery by reducing the pain, analgesic consumption after anterior cervical spine surgery.

Primary Outcome Measure The primary outcome measure is the global QoR-40 aggregate score at 24 hours after surgery.

Secondary Outcome Measures

  • Postoperative pain scores (first 24 hours)
  • Total analgesic consumption (first 24 hours)
  • Time for first opioid administration
  • Postop Nausea and vomiting (first 24 hours)
  • Post operative sedation (first 24 hours)
