Overview
- An interscalene nerve block is a regional anesthesia technique, usually performed under ultrasound guidance to provide anesthesia to the shoulder and the upper arm.[1]
Indications
- Post operative analgesia for shoulder surgery
- Humerus fracture
- Lacerations or abscesses of upper arm and deltoid
Contraindications
- Severe lung disease
- Due to risk of unilateral pneumothorax
- Overlying infection
- Allergy to anesthetics
- Phrenic nerve dysfunction
- Specifically contralateral phrenic nerve dysfunction, due to the risk of unilateral paralysis
Equipment Needed
- Linear Probe
- 25 g needle
- 5-10cc local anesthetic
Procedure
- Always check for the transverse cervical artery using color Doppler.
- Keep needle tip as far from the nerve roots as possible.
- Assume phrenic paralysis and avoid in patients with tenuous respiratory status.
Complications
- Phrenic nerve dysfunction[2]
- Causing unilateral diaphragmatic paralysis and respiratory distress.
- Pneumothorax[3]
- On the side of the nerve block
