The technique in this procedure was:
- obtain a localising scan with some way of demarcating the skin (in this case, a
radio-opaqueradiopaque 'grid') - choose a location that gives as vertical as possible route to the epidural space
- local
anestheticanaesthetic along proximaltracttrack (optional) - advance needle until slight resistance (often gritty) is felt
(ligamentum(ligamentum flavum) - check location
- attach empty syringe with 3-4 ml of room air and keep plunger pulled while advancing remaining distance
- epidural space has low / negative pressure and air is easily injected
- confirm the extrathecal location
- inject steroid and local
anestheticanaesthetic
