What this Trial Is About
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.
