II. Indications
- Anesthesia to anterolateral neck from clavicle to inferior and lateral ear
- Catheterization of Internal Jugular Vein
- Clavicle Fracture
- Laceration Repair
III. Anatomy
- Superficial Cervical Plexus (C2-4) supplies four superficial periopheral nerves
- Lesser Occipital Nerve
- Greater Auricular Nerve
- Transverse Cervical Nerve
- Suprclavicular Nerve
- Risk of adverse effects on nearby structures
- Carotid Artery and Internal Jugular Vein are medial to injection site
- Brachial Plexus is inferior to injection site
- Cervical plexus is deep to injection site
IV. Preparation
- Identify and mark landmarks
- Lateral neck (posterior aspect of sternocleidomastoid)
- Level of superior aspect Thyroid cartilage
- Skin Preparation (e.g. Chlorhexidine)
- Drape region
- Sterile covering over Ultrasound high frequency linear probe (sterile gel inside and outside)
- Medication
- Confirm maximum dose for Ropivacaine (or Bupivacaine ) to prevent LAST Reaction
- Ropivacaine 0.5% (preferred over Bupivacaine 0.25% to 0.5%) 10-15 ml
- Syringe 10-20 ml
- Needle 25-27 gauge, 1.25 to 1.5 inch
V. Technique
- Ultrasound in transverse plane over lateral neck
- Injection Plane
- Images
VI. Adverse Effects
- Recurrent laryngeal nerve transient paralysis (hoarse voice)
- Brachial Plexus Block (resulting arm motor and sensory effects)
- Horner's Syndrome
- LAST Reaction (as with any Nerve Block)
