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

Zagazig University58 enrolled

Overview

• 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

Outcomes

Primary Outcomes

The time to first call to rescue analgesia

The time to first call to rescue analgesia (nalbuphine) the time between the end of surgery to first report of postoperative pain. will be recorded.

Time frame: 24 hour postoperative

Secondary Outcomes

The total amount of nalbuphine

The total amount of nalbuphine given to each patient during the first 24h of postoperative period will be recorded

Time frame: 24 hour postoperative

Pain intensity

2\. Pain intensity using Visual Analouge Scale (VAS) (11). A commonly used visual analog scale is a 10-cm line labeled with "worst pain imaginable" on the right border and "no pain" on the left border. The patient is instructed to make a mark along the line to represent the intensity of pain currently being experienced. VAS score will be assessed at 30 minutes, 2hs, 4hs, 6hs, 12hs, and 24hs postoperative and IV increment of 15mg nalbuphine (rescue analgesic) will be given if VAS≥4.

Time frame: up to 24hs postoperative

Total intra-operative fentanyl consumption

Total intra-operative fentanyl consumption by ug excluding induction dose.

Time frame: intra-operative
