Group:

group 1

Sample size:

干预措施:

第一位患者采用的罗哌卡因的剂量为0.1%。有效定义为硬膜外注射负荷量30 min内的视觉模拟评分(VSA)≤3。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浓度增加或减少0.01%。采用probit法和Dxion法计算EC50。

干预措施代码:

Intervention:

The dose of ropivacaine used by the first patient was 0.1%. The effective definition is a visual analogue score (VSA) ≤ 3 within 30 minutes of epidural injection load. Determine the effective or ineffective response, and then use the up and down order method to increase or decrease the concentration of ropivacaine in the next mother's sheath by 0.01%. Calculate EC50 using probit and Dxion methods.

组别:

组2

样本量:

30

Group:

group 2

Sample size:

干预措施:

每位患者右美托咪定的剂量均为0.4ug/ml,第一位患者采用的罗哌卡因的剂量为0.1%。有效定义为硬膜外注射负荷量30 min内的视觉模拟评分(VSA)≤3。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浓度增加或减少0.01%。采用probit法和Dxion法计算EC50。

干预措施代码:

Intervention:

The dose of dexmedetomidine for each patient is 0.4ug/ml, and the dose of ropivacaine used for the first patient is 0.1%. The effective definition is a visual analogue score (VSA) ≤ 3 within 30 minutes of epidural injection load. Determine the effective or ineffective response, and then use the up and down order method to increase or decrease the concentration of ropivacaine in the next mother's sheath by 0.01%. Calculate EC50 using probit and Dxion methods.

随机方法(请说明由何人用什么方法产生随机序列):

使用计算机生成的随机列表,将同意的产妇根据纳入标准共60名,随机分为两组:C组(单纯罗哌卡因组)和Dex组(罗哌卡因+右美托咪定0.4μg/ml组)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Using a computer-generated random list, a total of 60 eligible parturients were randomly divided into two groups based on inclusion criteria: Group C (ropivacaine alone group) and Dex group (ropivacaine+dexmedetomidine 0.4 μ g/ml group).
