Frequently asked questions

How long will bupivacaine numbness last?

It is long-acting, so numbness can last several hours, which is why it is used for long operations and pain relief afterwards.

Is an epidural with bupivacaine safe in labour?

Yes, it is widely used. Staff monitor blood pressure and the baby throughout.

Why is it not used for IV regional anaesthesia?

Bupivacaine is especially toxic to the heart if large amounts enter the blood, so it is avoided there.
