Disease relevance of Cervical Plexus

• A double-blind, randomised, controlled trial of forty patients was carried out to determine if oral atenolol pretreatment would reduce the incidence of tachycardia during carotid endarterectomy performed under cervical plexus block [1].

High impact information on Cervical Plexus

• METHODS: Forty patients undergoing carotid endarterectomy were randomized to receive either a superficial or a deep cervical plexus block with 20 ml bupivacaine, 0.375% [2].
• All patients received a deep cervical plexus block with 30 ml ropivacaine 0.75% and were randomized to receive either remifentanil 3 micro g kg(-1) h(-1) or propofol 1 mg kg(-1) h(-1) [3].
• CONCLUSION: As a result of the higher incidence of adverse respiratory effects with remifentanil and similar sedative effects, propofol is preferable for sedation during cervical plexus block in elderly patients with comorbid disease at the dosage used [3].
• Deep cervical plexus block was performed with a single injection (8 mL) at the C3 level [4].
• Plasma concentrations of lidocaine and bupivacaine after cervical plexus block for carotid surgery [5].

Biological context of Cervical Plexus

• STUDY OBJECTIVE: To investigate the efficacy and kinetics of bupivacaine when used for deep cervical plexus block (CPB), using either a single-injection or multiple-injections technique [6].

Anatomical context of Cervical Plexus

• On both sides it was replaced by a vagocervical plexus formed by the vagus nerve and C1 and C2 ventral rami from the cervical plexus [7].

Associations of Cervical Plexus with chemical compounds

• We compared bupivacaine 0.5% and ropivacaine 0.75% for cervical plexus block (CB) [8].
• Twenty-one carotid endarterectomies were performed on 18 patients anaesthetised during droperidol, fentanyl and a cervical plexus block [9].
• PURPOSE: To evaluate the effectiveness of cervical plexus block performed with ropivacaine 0.75% or 1%, or mepivacaine 2% [10].
• Plasma bupivacaine concentrations and effects of epinephrine after superficial cervical plexus blockade in patients undergoing carotid endarterectomy [11].
• Four segmental nerves, C2 to C5, gave rise to all the cutaneous nerves and branches of the cervical plexus described [12].

Gene context of Cervical Plexus

• We describe a new technique for achieving a deep cervical plexus block using a portable vascular access ultrasound scanner (Site-Rite II, Bard Access Systems, Pittsburgh, PA) [13].

Analytical, diagnostic and therapeutic context of Cervical Plexus

• During this period, from 1977 to 1986, our administration of regional anesthesia has evolved from bilateral deep and superficial cervical plexus blocks to bilateral superficial blocks alone using bupivacaine with epinephrine, 1:200,000 [14].
• The objective of this study was to assess the analgesic efficacy in the first 36 postoperative hours after total thyroidectomy of bilateral superficial cervical plexus block with 0.75% ropivacaine administered before the incision or on completion of the surgical procedure [15].
• METHODS: In a prospective, randomized, double-blind study, 60 patients received deep cervical plexus block with 0.2 ml x kg(-1) divided among C2-C4 injections using ropivacaine 0.75% and 1% or mepivacaine 2% [10].
• In 28 patients, diaphragmatic motion was evaluated by fluoroscopy 20 min after cervical plexus block with 1% mepivacaine [16].
• After general anesthesia induction, bilateral superficial cervical plexus block with 0.25% bupivacaine 15 mL in each side was performed in Group I, and local anesthetic wound infiltration with 0.25% bupivacaine 20 mL was performed in Group II [17].
