研究设计:

随机平行对照 

Study design:

研究目的:

采用偏倚硬币序贯分配法,确定不同容积的局麻药注射液在剖宫产腰麻中罗哌卡因的ED50和ED90值,并比较不同容积的局麻药注射液在剖宫产腰麻中罗哌卡因的ED50和ED90是否存在统计学上的差异。  

Objectives of Study:

Objective to determine the ED50 and ED90 values of ropivacaine in spinal anesthesia of cesarean section with different volumes of local anesthetic injection by using the biased coin sequential distribution method, and to compare whether there are statistical differences in the ED50 and ED90 of ropivacaine in spinal anesthesia of cesarean section with different volumes of local anesthetic injection.
