Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Area of Science:

Anesthesiology
Vascular Surgery
Neurosurgery

Background:

Traditional superficial and deep cervical plexus blocks for carotid endarterectomy carry risks of cardiovascular, respiratory, and neurologic complications.
There is a need for safer and simpler anesthesia techniques for this procedure.

Purpose of the Study:

To evaluate the feasibility, effectiveness, and safety of an intermediate cervical plexus block combined with subcutaneous infiltration for carotid endarterectomy.

Main Methods:

183 patients undergoing primary carotid endarterectomy received an intermediate cervical plexus block using 0.75% ropivacaine, combined with subcutaneous infiltration of the incision line.
Intraoperative topical lidocaine or intravenous sedation/analgesia was used as needed.
Needle insertion was perpendicular to the skin along the sternocleidomastoid muscle's posterior border.

Main Results:

The technique was feasible and effective, with only 1.1% of procedures converted to general anesthesia.
Low complication rates were observed: 1.6% experienced postoperative stroke or myocardial infarction.
No perioperative deaths or major complications occurred.

Conclusions:

The intermediate cervical plexus block is a safe, feasible, and effective anesthesia method for carotid endarterectomy.
This technique offers a reduced risk profile compared to traditional combined superficial and deep cervical plexus blocks.
Further research can explore optimizing this anesthesia approach for carotid endarterectomy.
