Comparison of intrathecal bupivacaine and levobupivacaine combined with opioids for Caesarean section.

Objective: To date, racemic bupivacaine is the most popular local anaesthetic for spinal anaesthesia in parturients undergoing elective Caesarean delivery. However, data suggests that S-enantiomers like levobupivacaine may produce differential sensory and motor blockade. The aim of the present study was to compare fixed doses of intrathecal hypertonic levobupivacaine 0.
