A Comparison of Spinal Anesthesia Ropivacaine with Bupivacaine Used for Lower Abdominal Surgery

Objective To compare the clinical efficacy of spinal 0.75% ropivacaine with 0.75% bupivacaine in patients with lower abdominal surgery.Methods 40 ASA Ⅰ/Ⅱ patients were randomly divided into 2 groups (n=20 each):group R (the Ropivacaine group) and group B(the Bupivacaine group).Spinal anesthesia was performed at L2-3 interspace.The onset time of sensory block and motor block,duration of analgesia and motor block were recorded.Hemodynamic,side-effects were also recorded.Results There was no significant difference in sensory block between the two groups (P0.05).The onset time of motor block was significantly longer in group R than that in group B.The duration of motor block was significantly shorter in group R than that in group B.Conclusion 0.75% ropivacaine can give a satisfactory clinical effective(P0.01).The duration of motor block was shorter in group R than that in group B.It is beneficial for patients to recovery quickly.
