Objective:
To compare the standard method of combined (superficial and deep) cervical plexus block (SDCPB) with a medial cervical plexus block (MCPB).

Design:
A prospective, randomized, single blind study.


Setting:
Department of Anaesthesiology and Intesive Care Medicine, Tertiary Hospital.

Material and methods:
One hundred consecutive patients undergoing elective carotid endarterectomy (CEA) were randomized into two groups. The quality of the block, time to perform the block, nature and rate of complications and patient's as well as surgeon's satisfaction were assessed. Data was statistically analyzed using Pearson's χ2- and Mann-Whitney tests.

Results:
The groups did not differ in the quality of the block and there was no difference in the need for additional sedation or topical anesthesia applied by the surgeon. Time to perform the SDCPB was 5.48 min compared with 2.28 min for MCPB. Puncture of adjacent blood vessels occurred in 7 cases of SDCPB and none in MCPB. Satisfaction with both methods of nerve block was excellent and both among patients and surgeons. The total dose of local anesthetic was significantly reduced in the MCPB group (12.5 mg bupivacaine and 15 mg trimecain vs 6 mg of bupivacaine).

Conclusion:
The effectiveness of the medial cervical plexus block is comparable to the combined superficial and deep cervical plexus block. The risk of complications, dose of local anesthetic and procedural time favor the MCPB over SDCPB.
