What type of anesthesia will I have?
There are two main types:
Our surgeons strongly prefer that you have regional anesthesia if you can.
Regional uses a shot of medicine to numb part of your body. Hip replacement is often done this way. You could have a spinal or an epidural or combined spinal-epidural.
Spinal: We inject numbing medicine into the fluid around your spinal cord.
Epidural: We inject numbing medicine through a small tube close to your nerves.
Both work in the same way as numbing medicines that the dentist uses. You will feel numb below the waist from the spinal for 2-4 hours. An epidural can be used if you will need numbing medicine for more than 2-4 hours.
General anesthesia is used if regional is not the best option for you. You will be fully asleep and have a breathing tube. At the end of surgery, we take the breathing tube out and wake you up.
On the day of surgery, after you check into the preop area, your anesthesia doctor will talk with you about the pros and cons of both types. You and your doctor decide on the best option for you.
What is the regional anesthesia process?
The spinal or epidural is done while you sit up or lay on your side. You may get medicine to help you relax when it is being placed. The process is:
Your back is cleaned with germ-free soap.
We place a numbing medicine in your skin where the needle will go.
We insert the needle gently into your back. With a spinal, we inject the numbing medicine and all equipment is removed. With an epidural, a small, plastic catheter is placed (this catheter is about the width of a guitar string). You should feel very little pain during this step.
Will I still be asleep for surgery?It is normal with regional anesthesia for you to be sedated during surgery. You should not feel any pain because you will be numb. Most patients remember very little with sedation. They wake up faster and feel less groggy than with general anesthesia.
What are the risks?
Although very safe, there is a small risk of problems.
A drop in blood pressure
Numbness to only one side of your body
A “spinal” headache (1 out of 100 patients). This type of headache gets worse when you sit up and better when lying flat. These headaches can be severe, but we can treat them. They have few long-term side effects.
Infection or bleeding around the spinal cord (rare)
Nerve injury/numbness/weakness (rare)
The epidural can be placed into blood vessel (rare) which can have serious effects on heart rate, rhythm and breathing
Who should not get regional anesthesia?
Patients with bleeding problems
Patients with severe infections
Patients who have had nerve injuries
