Hello everyone
Here are some questions I have about spinal anaesthesia
1. I know it is usually done below L3 because that is where spinal cord ends and not done above that because spinal cord can get damaged. But can't a really skilled person give it above L3, because subarachnoid space ends before spinal cord? So if he stops at the right time wouldn't it work giving anaesthesia from a higher level.
2. Why does the spinal anaesthetic agent only act below the point it was administered. Can't it diffuse up and affect the whole spinal cord?
3. Why can you achieve higher level anaestheisa (Meaning from chest to toe) from epidural anaesthesia?
4. What is the difference between paraesthesia and numbness. Don't they both mean lack of senastion?
Thanks
