Levobupivacaine or ropivacaine: A randomised double blind controlled trial using equipotent doses in spinal anaesthesia

Conclusion Levobupivacaine produces significantly longer duration of analgesia than ropivacaine when used in a ratio of 0.6:1. Efficacy, toxicity and haemodynamic profile make ropivacaine suitable agent for surgeries with low threshold for hypotension.
