Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cervical plexus blocks are regional methods used in carotid endarterectomy. Cervical plexus blocks consist of three blocks: superficial, intermediate and deep. These three blocks can be used alone or combined. The aim of this study is to evaluate the effectiveness of ultrasound-guided intermediate and deed cervical plexus block in patients undergoing carotid endarterectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Carotid endarterectomy is a surgical method used to treat occlusive lesions of the carotid. Regional anesthesia is preferred because it allows for consciousness control and neurological examination during the operation. Cervical plexus blocks are regional methods used in carotid endarterectomy. It is a regional technique in which the cervical spinal nerves (C2-C3-C4) are blocked with a local anesthetic agent from different regions. Cervical plexus blocks consist of three blocks: superficial, intermediate and deep, depending on the depth at which the local anesthetic agent is infiltrated. According to the preference of the clinician for the purpose of anesthesia, these three blocks can be used separately or combined. It is mentioned that all three blocks provide sufficient anesthesia for carotid endarterectomy surgery to be performed.

In the study, investigators planned to evaluate the effectiveness of ultrasound-guided intermediate and deep cervical plexus blocks in patients undergoing carotid endarterectomy by comparing the number of patients who need additional local anesthetics.
