The application of ropivacaine subarachnoid block in Cesarean section

Objective To compare the anesthesia efficiency and safety of different concentrations of ropivacaine with bupivacain spinal anesthesia.Methods Sixty full-tern gravitas undergoing Cesarean section were divided into three groups with twenty cases each:0.5% ropivacaine group(L1), 0.75% ropivacaine group(L2),and 0.5% bupivacaine group(C). The onset and duration of sensory and motor block, adversre reactions, HR,BP,SpO2 during operation and Apgar score of neonates at 1 min and 5 min were recorded and compared. Results There was no significant difference in the three groups for the common conditions of pregnant women and the apart score of neon ales and tie incidence of adverse reactions. The onset and duration tine of sensory block and modifier bromide score(MBS)of motor block were different in three groups. The evaluation of intensity of pain and muscle relaxation was significant doffing. Conclusion The aesthesia efficiency of 0.75% ropivacaine is litter than 0.5% ropiacaine,but stronger than 0.5% bupivacaine.Three have the good safety.
