Abstract

Objectives: To compare the effect of epidural analgesia in labor with ropivacaine 0.125% - fentanyl and bupivacaine 0.125% - fentanyl. Subjects and methods: a comparative clinical intervention study. 60 pregnant women divided into 2 groups received analgesia to relieve pain during labor, group R used ropivacaine 0.125% and group B used bupivacaine 0.125%. Both groups were evaluated for the effectiveness of analgesia, the effect on the ability to push, the duration of labor and the undesirable effects. Results: The analgesia in labor of both groups was good. The mean VAS score after anesthesia of both groups was below 4 points. The time in stage 1b of group R was 166.8±133.1 minutes longer than that of group B 129.0±95.0 minutes. p>0.05. The time of phase 2 of group R was 21.54±16.1 minutes longer than that of group B of 19.0±14.4 minutes. p>0.05. Group B has 1 pregnant woman (accounting for 3.3%) with reduced feeling of tenacity. Group R has 100% of pregnant women with good pushing ability, while group B has 1 woman with reduced ability to push. Conclusion: Both groups had good analgesia in labor. The duration of stage 1b and stage 2 of group R was longer than that of group B. Group R had less influence on the sensation of straining and the ability to push to give birth than group B.
