Case Discussion

The technique in this procedure was: 

  1. obtain a localising scan with some way of demarcating the skin (this case radio-opaque 'grid')
  2. chose location that gives as vertical as possible route to epidural space
  3. local anesthetic along proximal tract (optional)
  4. advance needle to until slight resistance (often gritty) is felt (ligamentum flavum)
  5. check location
  6. attach empty syringe with 3 - 4 ml of room air, and ballote plunger while advancing remaining distance
  7. epidural space has low / negative pressure and air is easily injected. 
  8. confirm the extra-thecal location
  9. inject steroid and local anesthetic
