Is general anesthesia good or half anesthesia good for medical epidural puncture anesthesia needle?

"Local anesthesia doesn't matter", this is completely wrong!

Local anesthesia refers to the use of local anesthetics to temporarily block the conduction function of certain peripheral nerves, so that the corresponding areas innervated by these nerves produce anesthetic effects.

Local anesthesia can be divided into broad sense and narrow sense. The broad sense includes intraspinal anesthesia. This is what we call epidural anesthesia and lumbar anesthesia (subarachnoid anesthesia) or both.

Commonly used local anesthesia are: surface anesthesia, local infiltration anesthesia, regional block anesthesia, nerve block anesthesia.
