Ropivacaine 7.5 mg/ml for elective Caesarean section. A clinical and pharmacokinetic comparison of 150 mg and 187.5 mg

Abstract

20-25 ml ropivacaine 7.5 mg/ml produced very satisfactory conditions for elective Caesarean section under epidural anaesthesia. In this small population, 150 mg ropivacaine seemed optimal, while 187.5 mg produced unnecessarily extended block height in 50% of the women.
