Summary

Ultrasound real-time guidance technology has great advantages over traditional blind exploration technology in terms of accuracy, success rate, and reduction of puncture damage in intervertebral space positioning through operational visualization, greatly improving the effectiveness and safety of spinal block. At present, Doppler ultrasound is rarely used for spinal block, especially for real-time ultrasound guidance technology, which has not been widely applied in clinical practice due to its high equipment requirements, lack of mature puncture plans, complex operation, and high learning curve. If a comprehensive diagnosis and treatment plan can be developed, it will greatly improve the delivery experience of mothers.

Detailed description

Traditional blind exploration of spinal canal puncture has many limitations, often forcing changes in anesthesia methods due to multiple puncture failures. However, the application of real-time ultrasound guidance technology in spinal canal puncture can completely solve this clinical difficulty. The ultrasound-guided real-time paramedian approach epidural puncture for labor analgesia is a new type of labor analgesia technology, and its specific operating standards and diagnostic and treatment routines have not yet been established, including the selection of puncture path, puncture needle model, distance between puncture hole and epidural injection point, drug type, dosage, solubility, volume and other parameters, all of which have great research space.

Interventions

Type	Name	Description
DEVICE	Ultrasound Real-time Guidance combined with Dural Puncture Epidural Labor Analgesia	Ultrasound real-time guidance technology has great advantages over traditional blind exploration technology in terms of accuracy, success rate, and reduction of puncture damage in intervertebral space positioning through operational visualization, greatly improving the effectiveness and safety of spinal block.
DEVICE	Dural Puncture Epidural Labor Analgesia	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.
