creating a pathway for local anesthetics to reach the spinal cord is not the main goal of this technique. Local anesthetics are injected into the epidural space, not the subarachnoid space.

The purpose of intentionally puncturing the dura mater with a needle in this technique is to allow cerebrospinal fluid to leak into the epidural space and enhance the spread of local anesthetics. This technique is a modification of the combined spinal epidural technique, which involves injecting medication into both the epidural and the subarachnoid spaces. The dural puncture epidural technique aims to avoid the side effects of the combined spinal epidural technique, such as hypotension, pruritus, and urinary retention.

reducing the pressure in the subarachnoid space and preventing spinal headache is not the purpose of this technique. In fact, dural puncture epidural technique may increase the risk of spinal headache compared to conventional epidural technique.

stimulating the production of endorphins and providing natural pain relief is not related to this technique.

Endorphins are endogenous opioids that are released by the central nervous system in response to stress or pain. They are not affected by dural puncture or local anesthetics.
