Nerve Block: Occipital
(Redirected from Greater occipital nerve block)
- Therapeutic and diagnostic for occipital neuralgia
- Nerve is between ~8-18 mm deep
- Suspected or confirmed occipital neuralgia
- Migraine refractory to conservative treatment
- Post-lumbar puncture headache refractory to conservative treatment
- Cluster headache, occipital neuralgia, cervicogenic headache, or migraine with occipital nerve irritation or tenderness 
- Infection overlying injection site
- Syringe and 27-30ga needle
- Betadine or chlorhexidine
- Local anesthetic
- 40mg of methylprednisolone or triamcinolone may be mixed with the local anesthetic, but efficacy has not been proven.
- Patient in position of comfort allowing access to posterior head and neck. (laying prone or sitting with head down in arms)
- Identify Greater Occipital Nerve (GON).
- Cleanse skin with betadine or chlorhexidine and allow to dry
- Insert needle over nerve at 90 degrees to skin until hit bone, then withdraw slightly
- If using ultrasound, insert needle at 45 degrees to skin and advance toward nerve under direct ultrasound guidance
- Aspirate to ensure not in vessel.
- Inject ~1-3 mL of local anesthetic. (may inject small amount medial and lateral to nerve to ensure adequate block)
- Repeat on contralateral side, if indicated.
Maximum Doses of Anesthetic Agents
|Agent||Without Epinephrine||With Epinephrine||Duration||Notes|
|Lidocaine||5 mg/kg (max 300mg)||7 mg/kg (max 500mg)||30-90 min||
|Mepivicaine||7 mg/kg||8 mg/kg|
|Bupivicaine||2.5 mg/kg (max 175mg)||3 mg/kg (max 225mg)||6-8 hr||
|Tetracaine||1 mg/kg||1.5 mg/kg||3hrs (10hrs with epi)|
|Procaine||7 mg/kg||10 mg/kg||30min (90min with epi)|
Complications are rare due to superficial location and lack of major surrounding structures.
- Damage to surrounding structures
- Follow up with appropriate specialist for the indication for nerve block.
