研究目的:

我们假设, DPE或EP技术相比,用于分娩镇痛的DPE技术在镇痛作用开始、镇痛评分、局麻药消耗、副作用和母亲满意度方面可能提供更大的好处,同时联合硬膜外给予适量的右美托咪定,通过穿透的硬脊膜及蛛网膜孔进入蛛网膜下腔,能够快速抑制并达到较好的镇痛效果,减少爆发痛带来的母婴不良反应。因此,我们设计进行一项前瞻性、随机、对照研究,以评估DPE技术联合右美托咪定用于分娩镇痛的有效性和安全性,以期为分娩镇痛中爆发痛的发生带来快速有效的抑制方法,为产妇提供更安全有效的分娩镇痛方式。  

Objectives of Study:

We assume that compared to DPE or EP technology, DPE technology used for labor analgesia may provide greater benefits in terms of analgesic onset, analgesic score, local anesthetic consumption, side effects, and maternal satisfaction. At the same time, when combined with epidural administration of appropriate amounts of dexmedetomidine, it can quickly inhibit and achieve better analgesic effects by penetrating the dura mater and arachnoid foramen into the subarachnoid space, reducing maternal and infant adverse reactions caused by burst pain. Therefore, we designed a prospective, randomized, controlled study to evaluate the effectiveness and safety of DPE technology combined with dexmedetomidine for labor analgesia, with the aim of providing a rapid and effective method for inhibiting the occurrence of burst pain in labor analgesia and offering a safer and more effective way of labor analgesia for mothers.

Intervention:

Group A parturients underwent routine L2-L3 epidural puncture, and after successful puncture, an external dura mater tube was routinely performed.

干预措施代码:

Intervention:

Group B parturients underwent routine L2-L3 epidural puncture. After successful puncture, Group B used a 25G puncture needle for subarachnoid puncture. After successful puncture, no medication was administered to the subarachnoid space, and the 25G puncture needle was directly withdrawn. Subsequently, routine epidural catheterization was performed. Group B received an initial dose of 7ml of 0.1% ropivacaine+0.5 μ g/ml dexmedetomidine mixture in the epidural space, followed by maintenance with the same mixture. The maintenance dose was set at 8ml, with an additional 6ml added and locked for 20 minutes.

Group C parturients underwent routine L2-L3 epidural puncture. After successful puncture, Group C used a 25G puncture needle for subarachnoid puncture. After successful puncture, no medication was administered to the subarachnoid space, and the 25G puncture needle was directly withdrawn. Subsequently, all parturients underwent routine epidural catheterization. Group C received an initial dose of 7ml of 0.1% ropivacaine+0.5 μ g/ml sufentanil mixture in the epidural space, followed by maintenance with the same mixture.
