Need to withdraw after dural puncture?

The epidural catheter must be withdrawn immediately after insertion to check for cerebrospinal fluid and blood. After lying down, the local anesthetic should also be withdrawn before injection to ensure that the local anesthetic is not injected into the blood vessel or subarachnoid space as much as possible.

Although combined spinal-epidural anesthesia seems simple, we should be careful in every aspect of it. I hope everyone can share and communicate, provide some valuable experiences and opinions, and learn from each other! thank you all!
