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. conditions: Labor Analgesia studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL primaryPurpose: TREATMENT masking: TRIPLE whoMasked: PARTICIPANT whoMasked: CARE_PROVIDER whoMasked: OUTCOMES_ASSESSOR count: 80 type: ESTIMATED name: Ultrasound Real-time Guidance combined with Dural Puncture Epidural Labor Analgesia name: Dural Puncture Epidural Labor Analgesia measure: Analgesic effect（onset time） measure: Analgesic effect（block level） measure: Analgesic effect（block effect） measure: Analgesic effect（Visual Analogue Scale） measure: Analgesic effect（number of Patient controlled analgesia） measure: Analgesic effect（time of Patient controlled analgesia） measure: Uterine contraction indicators（Frequency） measure: Uterine contraction indicators（duration） measure: Uterine contraction indicators（Number of pregnant women with Tachysystole） measure: Uterine contraction indicators（Number of pregnant women with hypertonus） measure: Fetal heart indicators（Fetal heart rate） measure: Fetal heart indicators（NICHD classification） measure: Fetal heart indicators（Fetal Heart Rate decelerations） measure: Fetal heart indicators（Fetal Heart Rate Variability） measure: Apgar score measure: Sacral sensory block of pregnant women measure: modified bromage score measure: Operation evaluation（Time） measure: Operation evaluation（number of times） measure: Operation evaluation（side effects and Complications） measure: Delivery mode measure: Concentration of Interleukin 6 measure: Concentration of hypersensitive C-reactive protein measure: Concentration of cortisol measure: Maternal rehabilitation indicators（Postpartum hospital stay） measure: Maternal rehabilitation indicators（Edinburgh Postnatal Depression Scale） measure: Maternal rehabilitation indicators（Postoperative Recovery Quality Scale（QOR-40）） measure: Number of pregnant women with adjust the treatment plan and adjustment method measure: Drug consumption measure: Effect of stages of labor（time） measure: body temperature changes measure: Number of pregnant women with Infection during labor measure: Side effects and complications of labor analgesia measure: The reasons and number of pregnant women with conversion of natural labor to Caesarean section measure: Self-Rating Anxiety Scale measure: Delivery fear score（numerical rating scale） measure: Delivery satisfaction survey sex: FEMALE minimumAge: 20 Years maximumAge: 45 Years stdAges: ADULT facility: Fujian Provincial Hospital status: RECRUITING city: Fuzhou state: Fujian zip: 350001 country: China name: Zongxun Lin, Master role: CONTACT phone: +8613763820916 email: 13763820916@189.cn lat: 26.06139 lon: 119.30611 hasResults: False
