Episode notes
Target Deep To The Erector Spinae Fascia
- Aim deep to be under the erector spinae muscle fascia, not just superficial between muscle layers.
- Pop through to the corner of the transverse process to ensure spread under the muscle sheath.
ESP Works Despite Limited Ventral Dye Spread
- Cadaver studies often show dye staying posterior to the transverse process yet clinicians still observe analgesia.
- This suggests mechanisms beyond simple ventral spread explain ESP clinical effects.
Host's Personal ESP Test
- Amit had an ESP performed on himself with 30 mL of 1.5% prilocaine and gained a numb patch only on his back.
- He felt systemic jitteriness but did not develop LAST; the block lacked anterior trunk sensory change.
