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
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
