Summary
Superficial cervical block offers similar efficacy to combined cervical block for carotid endarterectomy. Superficial block also shows a lower incidence of anesthetic complications, without impacting patient outcomes.
Area of Science:
- Anesthesiology
- Vascular Surgery
Background:
- Carotid endarterectomy (CEA) is a surgical procedure to remove plaque from carotid arteries.
- Cervical plexus blocks are used for anesthesia during CEA.
Purpose of the Study:
- To compare combined (superficial plus deep) and superficial cervical plexus blocks for CEA.
- To evaluate anesthetic efficacy, patient/surgeon satisfaction, complications, and outcomes.
Main Methods:
- 125 patients undergoing elective CEA were randomized into two groups.
- Group 1 received superficial cervical block; Group 2 received combined cervical block.
Main Results:
- No significant difference in anesthetic quality or surgical conditions between the two block types.
- Complications were slightly higher in the combined block group (7.4%) versus superficial block (1.6%).
- Anesthetic supplementation was required in 81.96% of patients, with no significant difference between groups.
Conclusions:
- Superficial cervical block is as effective as combined block for CEA.
- Combined block has a higher incidence of anesthetic-related complications.
- The type of cervical block does not influence the final patient outcome.
