What happens if the needle core is not inserted when the puncture needle is finally removed during lumbar puncture

The needle core should be inserted when the needle is inserted or withdrawn because:

A. A puncture needle without a core may bring small epidermal emboli into the subarachnoid space during puncture;

B. When the coreless puncture needle is withdrawn, some nerve root fibers may be inhaled, causing pain.

From: Lumbar Puncture Operation Specification

Here are my own views:

Complications are unlikely, but "final removal of the needle without the core" carries the potential risk of damaging some of the tiny nerve fibers. If you think about it, on the other hand, I personally think that reinserting the needle core when it is pulled out has the risk of bringing external infectious substances into the subarachnoid space, so the aseptic operation during the puncture process is very important. .
