This anaesthetic involves blocking the nerves that supply the area where the surgeon will be operating. This reduces the number of anaesthetic drugs we need to give which in turn reduces the side effects - feeling sick for example.
The cervical plexus block is predominantly used for surgery on the carotid artery. It involves having local anaesthetic injected into the neck to numb the nerve supply to the artery and its surrounding structures. The surgery is then quite often performed without the need for a general anaesthetic, although your anaesthetist may offer you some sedation.
The risks of this block are minimal, but include:
- A temporary change in the quality of your voice or hoarseness
- Change in your breathing sensation
- A temporary numbness and drooping of one side of your face
