Summary

Dural Puncture Epidural is a clinical improvement of Combined Spinal-Epidural and is widely used in Maternal.Dural Puncture Epidural Technique improves Labor Analgesia Quality And Safety By Increasing Drug Permeation.This study combines ultrasound real-time guidance technology. This technology ensures the accuracy of intervertebral space positioning and puncture success rate through operational visualization, and reduces the impact of operator proficiency on research results.

Detailed description

Dural Puncture Epidural is a clinical improvement of Combined Spinal-Epidural and is widely used in Maternal. The implementation step is to complete the epidural puncture, temporarily do not place a tube, puncture the dura mater with a subarachnoid anesthesia needle, but do not directly inject drugs into the subarachnoid space, and then leave an epidural catheter for administration according to epidural block. The theoretical basis is that anesthetic drugs can originally penetrate into the subarachnoid space from the epidural space through a complete spinal dura, and the puncture hole formed by spinal dura puncture facilitates this process.After injecting high volume anesthetic drugs into the epidural space, the pressure increases, and the drug penetrates from the epidural space through the puncture hole along a pressure gradient to the subarachnoid space, thereby enhancing the effect of labor analgesia.Dural Puncture Epidural also has the advantage of verifying that the epidural needle is in the middle of the epidural space again, thereby reducing the incidence of epidural catheter insertion failure or deviation to one side.This study combines ultrasound real-time guidance technology. This technology ensures the accuracy of intervertebral space positioning and puncture success rate through operational visualization, and reduces the impact of operator proficiency on research results.
