Intermediate Cervical Block Under Ultrasound for Thyroid Surgery: Impact on Per and Postoperative Opioid Consumption

Bilateral Intermediate Cervical Plexus Block Under Ultrasound for Thyroid Surgery: Impact on Perioperative Opioid Consumption

The investigators included prospectively 35 patients undergoing an intermediate cervical block under ultrasound (GP1) before a thyroidectomy ,compared to a group of 35 patients without a block (GP2).

The investigators performed prospective trial with 70 patients randomized in two groups each of 35:

• Group 1 (GP1): bilateral echo-guided intermediate cervical plexus bloc (ICB) by 10 ml of isobaric Bupivacaine (0.25%).
• Group 2 (GP2): control.

Ten minutes after ICB, general anesthesia was realised. Total dose of Remifentanil is calculated upon awakening, the postoperative pain is determined by visual analog scale from 0 to 10 (VAS) statements to H0, H2, H4, H6, H12 and H24. Whenever VAS is greater than or equal to 4, a morphine titration was administered.

Total dose consumption, side effects and satisfaction are noted at the end of protocol.
