(1) Group D: cervical plexus blocking.

(2) Objective To observe the clinical effect of superficial cervical plexus blocking anesthesia with local anesthesia plus dexamethasone in surgical treatment of patients with thyroid adenoma.

(3) Conclusion The functional neck dissection preserving cervical plexus can improve the survival quality of patients, and can′t increase the recurrence rate of lymph node of neck.

(4) Tramadol can improve the analgesic efficacy of cervical plexus block and attenuates the cardiovascular responses.

(5) Purpose:To discuss the functional neck dissection preserving cervical plexus in the treatment of differentiated thyroid cancer.

(6) Objective: To summarize the experience for treatment of shoulder and neck pain caused by cervical plexus compression with regional block.

(7) Objective To explore clinical application of the functional neck dissection preserving cervical plexus in thyroid cancer.

(8) The density of lymphatic tubes around the internal jugular vein, accessory nerve and sternocleidomastoid muscles was much higher than that around the external jugular vein and cervical plexus.

(9) We found that effects of bupivacaine was better than other local anesthetics in cervical plexus block.

(10) Conclusion Neostigmine can safely and effectively treats cardiovascular response during cervical plexus block anesthesia of thyroid surgery, but the patients must be elected.

(11) Methods:15 cases of papillary thyroid cancer underwent functional neck dissection while preserving the cervical plexus.

(12) Objective To evaluate effects on sub - thyroidectomy with anesthesia of ameliorated cervical plexus block.

(13) AIM: To introduce the clinical experience of the use of cervical plexus block in behind-the-ear incision mastoidectomy.

(14) Objective: To observe the rami communicans between the spinal accessory nerve and the cervical plexus by dissection in order to provide a reliable anatomical basis for clinical application.

(15) Objective: To explore the clinical application of neck dissection preserving cervical plexus nerve in thyroid cancer.

(16) Conclusion Nicardipine can safely and effectively control the presence of hypertension responses during thyroidectomy under cervical plexus nerve block.

(17) Objective To observe the influence of the mix of fentanyl, lidocaine and bupivacaine on heart rate and blood pressure in cervical plexus block anaesthesia.

(18) Objective To explore the effect of inhalation-intravenous general anesthesia combined with cervical plexus block in the thyroid surgery.

(19) Objective To observe the analgesic effects and adverse effects, and safety of cervical plexus combined with epidural block on thyro-operation.

(20) Objective:To investigate the effect of low-dose ketamine in prevent neurotonic reaction in thyroidotomy with cervical plexus blockade.
