Epidural 0.2% ropivacaine for labour analgesia: Parturient-controlled or continuous infusion?

In this randomized open study we compared the incidence of lower limb motor block associated with epidural labour analgesia provided by parturient-controlled method (PCEA) with continuous infusion (CIEA) using 0.2% ropivacaine. The PCEA group (n=20) received a demand-only regimen (bolus 5 ml, lockout 15 minutes). The rate of infusion of the CIEA group (n=20) was 8 ml/h. We Sound that pain relief was not significantly different between the two groups, although the PCEA group had a higher satisfaction score (P<0.05). Fewer-parturients in the PCEA group had lower limb motor block (6 vs 14, P<0.05). The total volume of ropivacaine used per hour was also lower in the PCEA group (median 8.75 vs 10.5 ml P<0.05). No difference in the maternal or fetal outcome was detected We conclude that PCEA with ropivacaine is an effective mode of analgesia which is dose-sparing and produces less motor block in comparison with CIEA.
