Early studies suggested that Ropivacaine had clinical advantages over Bupivacaine with respect to cardio toxicity and motor block, and that it was suitable for epidural caesarean section. This study was set up to compare epidural 0.75% Ropivacaine with a popular 0.5% Bupivacaine for elective caesarean section.
60 women having elective caesarean section under epidural anaesthesia were randomly allocated to receive 18- 20 mL of either 0.75% Ropivacaine or 0.5% Bupivacaine.. Times were recorded for onset of sensory block, density and duration of motor block, and the need for supplementation.
The mean time taken to achieve sensory block at T10 was 9.33+/-2.54 min in group B and 11.33+/-2.60minutes in group R. In group B 93.33% patients had achieved T10 level with in 10 min as against 76.67%in group R. In group B 6.67% patients had achieved T10 level after 10 min as against 23.33% patients in group R. However, Ropivacaine produced a motor block that was denser time to achieve modified bromage score 3 was10 to 25 minutes in group and 10–30 minutes in group R. The mean time taken to achieve modified bromage score 3 was 15.83+/-2.96 minutes in group Band 16.33+/- 3.7 min in group R
This study suggests that epidural 0.75% Ropivacaine may be used as an alternative to Bupivacaine 0.5% for elective caesarean section, with a denser and prolonged motor block. With the onset time of anaesthesia
