Group:

group 1

Sample size:

干预措施:

每位患者右美的剂量均为3ug,第一位患者采用的罗哌卡因的剂量为10mg。有效定义为在注射鞘内给药后10分钟内通过针刺达到双侧T6或以上感觉阻滞水平,术中无需追加额外硬膜外麻醉或静脉镇痛。确定有效或无效反应,然后使用上下顺序法,下一位产妇鞘内罗哌卡因剂量增加或减少0.5mg。采用probit法和Dxion法计算ED50。

干预措施代码:

Intervention:

Each patient received a dose of 3ug of dexamethasone, and the first patient received a dose of 10mg of ropivacaine. Effectively defined as achieving bilateral T6 or above sensory blockade level through acupuncture within 10 minutes after intrathecal administration, without the need for additional epidural anesthesia or intravenous analgesia during surgery. Determine the effective or ineffective response, and then use the up and down order method to increase or decrease the intrathecal dose of ropivacaine by 0.5mg for the next mother. Calculate ED50 using probit and Dxion methods.
