Overview
- Injection of local anesthetic around the thoracic intercostal nerves to provide regional anesthesia to the anterolateral chest wall
Indications
- Rib fractures [1]
- Rib contusions
Contraindications
- Overlying soft tissue infection
- Allergy to local anesthetic
Equipment Needed
- Ultrasound (linear transducer) w/ sterile probe cover
- Sterile gloves
- Chlorhexidine or betadine solution
- 1% lidocaine with epinephrine in syringe with 27-gauge needle (for skin wheel)
- 0.5% or 0.25% bupivacaine in 30 ml syringe.
- 18 gauge blunt needle
- 22-25 gauge peripheral nerve block needle with extension tubing
- Alternatively, 22g spinal needle with IV extension tubing
Procedure
- Position patient in supine or lateral decubitus position (injured side up)[2]
- Sterilize skin w/ antiseptic solution
- Inject wheal of lidocaine into injection site
- Place ultrasound probe lateral to the nipple in transverse orientation
- Find the serratus anterior muscle overlying the ribs in the lateral chest wall
- Using the in-plane technique, advance needle with dominant hand
- Identify the pleural line prior to inserting the needle
- Advance the needle toward the rib (you will feel a pop once through the fascia)
- Connect tubing to needle and syringe.
- Push 2-3 cc to confirm placement between the serratus anterior and latissimus dorsi. The two should separate freely.
- Inject the remaining anesthetic
Complications
- Nerve injury
- Vascular injury
- Rebound pain
