Spinal and Epidural Anesthesia
(Spinal Block; Epidural Block)
These 2 types of anesthesia numb your body from the chest down to the legs. The medication is placed directly into the spine area.
Reasons for Procedure
Spinal and epidural anesthesia is frequently given for:
Advantages of these types of anesthesia include:
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Severe headache or back pain
- Drop in blood pressure
- Nerve damage
- Allergic reaction to the anesthetic used
- Longer labor during childbirth with an epidural anesthesia
Some factors that may increase the risk of complications include:
- Bleeding disorders
- Prior allergic reactions to anesthetics
- Immune system disorders
What to Expect
Prior to Procedure
Make sure that your doctor is aware of:
- Any drug allergies
- Medications you are taking
- Any heart or lung conditions you have
- Any previous reactions that you or other family members have had to anesthesia
- Any bleeding problems you have had in the past
Description of the Procedure
You will be connected to various monitors to keep track of your:
- Blood pressure
- Oxygen content of your blood
You may also have:
- An IV to deliver fluids
- A tube in your bladder to keep urine drained
An area on your back above the spinal cord will be cleaned. A local anesthetic will be injected into the skin to numb the area. This is to decrease pain from the larger needle that will be put in your back. If you are getting spinal anesthesia, the doctor will give you one injection. The medication will be sent directly into the sac of fluid that surrounds the spinal cord.
If you are getting epidural anesthesia, it may be delivered the same way. But, if you need more than one dose, you will have a tiny, flexible tube in place just outside of the fluid sac. This allows the doctor to give you more medication if you need it. After the surgery, a bandage will be placed over the injection spot.

Immediately After Procedure
You will stay in bed until your legs are no longer numb.
How Long Will It Take?
Giving spinal or epidural anesthesia usually takes about 15 minutes.
- Spinal anesthesia—begins working right after the injection is given
- Epidural anesthesia—takes about 10-20 minutes to begin working
How Much Will It Hurt?
You will feel some pain when the needle is inserted.
Average Hospital Stay
Your hospital stay depends on the type of surgery being done.

If you received epidural anesthesia, the tube may be left in place to give you more medication. When you no longer need pain control, the tube will be removed.
For the first 24 hours:
- Do not drive or operate machinery
