Nerve Block: Supraorbital: Difference between revisions

Revision as of 11:02, 9 August 2015

Indications

Supraorbital block provides facial anesthesia to the upper eyelid, forehead, anterior 1/3 of scalp for procedures (closure of lacerations, debridement) without distorting the soft tissues as seen with local infiltration

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 epi, 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

Place patient in supine position or seated
Obtain informed consent
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
