Question: what drugs are used for regional anesthesia?
Answer: Either heavy bupivacaine 0.5% or plain bupivacaine 0.5% is the commonly used. Fentanyl 15 to 25 micrograms is commonly added to improve the quality of block. Epidural anaesthesia is produced by injecting a large volume (10-20ml) of local anaesthetic drug in the epidural space.
