摘要

目的:在剖宫产手术中，稳定血流动力学、充分的镇静、镇痛对于产妇和新生儿是非常重要的，需要降低术中疼痛反应，避免血压波动过大，保证良好的镇静镇痛，降低母婴术后并发症的发生。硬膜外麻醉镇痛效果确切、麻醉平面较易控制、对产妇呼吸循环影响小，而全身麻醉药物有不明确的胎儿毒性作用，因此硬膜外麻醉成为剖宫产术的首选麻醉方式。硬膜外麻醉通常应用局部麻醉药物，右美托咪定（dexmedetomidine，DEX）作为一种辅助麻醉药物，与局部麻醉药有协同作用，与局麻药联合应用于硬膜外麻醉可延长脊髓镇痛时间。但是，对于剖宫产术中罗哌卡因硬膜外麻醉应用 DEX 作为佐剂的剂量，还没有具体的参考标准，尚需进一步探寻剖宫产硬膜外麻醉药物及佐剂的配方，本文就右美托咪定在硬膜外麻醉中应用最新研究作一综述。
