Background
- Supraorbital nerve innervates the ipsilateral upper eyelid, forehead, and anterior 1/3 of scalp
- Nerve block provides regional anesthesia without distortion of soft tissue seen in local infiltration
Indications
- Trauma or need to perform painful procedure on area innervated by supraorbital nerve
Contraindications
- Infection overlying injection site
- Previous allergic reaction to local anesthetic
- Uncooperative patient
- Distortion of anatomical landmarks
Equipment Needed
- local anesthesia
- lidocaine 1% (lasts 30-60 minutes or longer if given with epinephrine, rapid onset of 4-6 minutes)
- Bupivacaine 0.5% (lasts 2-4 hours, slowest in onset)
- 18 gauge needle to draw up anesthetic
- 1.5 inch 25 or 27 gauge needle
- 6cc syringe
- gauze pads
- gloves
- betadine/chlorhexidine
Procedure
- Obtain informed consent
- Place patient in supine position or seated
- Draw up 2-5cc of anesthetic into syringe
- Palpate the supraorbital foramen over the medial aspect of the supraorbital ridge
- Prep area
- Advance the needle towards foramen (5-10mm)
- Aspirate, and if no blood, inject 1-3 cc of anesthetic slowly
- Massage area for 10-15 seconds
Complications
- Bleeding/hematoma
- Infection
- Pain
- Swelling of face/eyelid
- Allergic reaction to anesthetic
- Damage to nerves/vessels
