研究目的:

通过临床观察静脉注射不同剂量右美托咪定对分娩镇痛产妇及新生儿的影响,以期从MAPK/ERK信号通路揭示其在分娩镇痛中的分子生物学机制;并通过动物实验进一步揭示不同剂量右美托咪定在分娩镇痛中的作用,并从MAPK/ERK信号通路分析其在分娩镇痛中作用的可能机制。为探索一种对母婴安全有效的分娩镇痛药物配伍方法,为该药物在分娩镇痛中的广泛应用提供科学依据。  

Objectives of Study:

Through clinical observation of the effects of intravenous injection of dexmedetomidine of different doses on labor analgesia in puerpera and neonates, the molecular biological mechanism of labor analgesia was revealed from the MAPK/ERK signaling pathway.The effect of dexmedetomidine in labor analgesia was further verified by animal experiments, and the possible mechanism of its effect in labor analgesia was analyzed from the MAPK/ERK signaling pathway, so as to explore a safe and effective method for the combination of labor analgesia drugs for mothers and infants, and to provide scientific basis for the widespread application of dexmedetomidine in labor analgesia
