Abstract:
Objective: To investigate a moderate dose of levobupivacaine in spinal anesthesia for caesarean section.Methods: Eighty parturients undergoing caesarean section were randomly divided into 4 groups: GroupⅠ(0.75% levobupivacaine 1.00ml+10% glucose 1.00ml+cerebrospinal fluid 1.00ml),GroupⅡ(0.75% levobupivacaine 1.33ml+10% glucose 1.00ml+ cerebrospinal fluid 0.67ml),Group Ⅲ(0.75% levobupivacaine 1.67ml+10% glucose 1.00ml+ cerebrospinal fluid 0.33ml) and Group Ⅳ(0.75% levobupivacaine 2.00ml+10% glucose 1.00ml).The spinal puncture sites were all located at L_2,3.The onset time of sensation block,the highest plane of analgesia,the time to reach the highest plane of analgesia,the time of regression to the L_1 segment,the degree of motor block,VAS scores,the degree of muscle relaxation,the rate of hypotension incidents and neonatal Apgar scores were recorded. Results: There were no statistically significant differences in the onset time of sensation block,the time to reach the highest plane of analgesia and the highest plane of analgesia among the 4 groups.But the durations of regression to the L_1 segment were dramatically shorter in GroupⅠand Ⅱthan in Group Ⅲ and Ⅳ(P
