What are the risks of an epidural?

An epidural is a regional anesthetic whereby a large gauge needle is placed in the epidural space, which is just outside of the spinal canal. When placing the epidural, local anaesthetic is used to limit the amount of pain during the procedure. When placing an epidural, sometimes you have to walk off the bone or the lamina of the vertebrae. The needle can bruise that bone and there can be some post-operative discomfort in the site. Once the epidural is activated and the local anesthetic is placed in the epidural space, it's possible that the vasodilatation from the sympathectomy that the patient receives will cause a drop in the blood pressure. That will have to be treated with fluids. When the blood pressure drops after an epidural, which it rarely does, but it does, the patient may become nauseous and may become dizzy. That has to be treated with vasopressures to bring the blood pressure back to eliminate those symptoms.
