Abstract

Objective: To evaluate the analgesic effects on labor of patient controlled epidural analgesia (PCEA) with ropivacaine at concentrations of 0.075%; 0.1% and 0.125% combined with fentanyl 2mcg/ml. Subject and method: A randomized clinical trial comparing 90 women who received PCEA, divided into three groups, using a ropivacaine concentration of 0.075%; 0.1% and 0.125% combined with fentanyl 2mcg/ml. Result: During the Ib stage of labor, three concentrations of ropivacaine showed adequate pain relief with > 90% of women with VAS < 4. During the second stage of labor, 26.7% patients in the ropivacaine 0.075% group did not have adequate pain relief with VAS > 4. Conclusion: Patient controlled epidural anesthesia - PCEA (initial bolus dose of 10ml, bolus dose per 5ml, 5 minutes interval) with ropivacaine at 0.125% in combination with fentanyl 2mcg/ml is suitable for pain management during labor.
