A nurse is assisting an anesthesiologist with performing dural puncture epidural (DPE) anesthesia for a client in labor.
What is the purpose of intentionally puncturing the dura mater with a needle in this technique?
To create a pathway for local anesthetics to reach the spinal cord
To allow cerebrospinal fluid to leak into the epidural space and enhance the spread of local anesthetics
To reduce the pressure in the subarachnoid space and prevent spinal headache
To stimulate the production of endorphins and provide natural pain relief.
The Correct Answer is B
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.
