A powerful local anaesthetic, used in epidural anaesthesia.
A potent local anesthetic, used mainly for regional ‘nerve block. It is significantly longer-acting than many other local anesthetics. It has been used in childbirth, but may cause slowing of the baby’s heart, with a risk of death.
A local anaesthetic, about four times as potent as lidocaine. It has a slow onset of action (up to 30 minutes for full effect), but its effect lasts up to eight hours, making it particularly suitable for continuous epidural analgesia in labour. It is commonly used for spinal anaesthesia, particularly lumbar epidural blockade. It is contraindicated in intravenous regional anaesthesia.
A prolonged-acting regional anesthetic frequently employed as a nerve blockade during labor and in the administration of epidural anesthesia and spinal anesthesia. Adverse reactions are infrequent, although elevated doses may induce a decline in blood pressure.
