研究目的: |
本研究拟通过偏硬币设计序贯法采用EPL+PIEB+PCEA模式确定硬膜外低浓度罗哌卡因复合阿芬太尼用于产妇分娩镇痛时程序性间歇硬膜外推注的最佳间隔时间,为临床实践提供更优化的分娩镇痛方案。 |

|
Objectives of Study: |
This study aims to determine the optimal interval time for programmed intermittent epidural infusion of ropivacaine combined with alfentanil for labor analgesia in patients by using the sequential method based on biased coin design, in the EPL + PIEB + PCEA mode. This will provide a more optimized labor analgesia plan for clinical practice. |
