What is intrathecal analgesia (IA)?
IA is a type of pain control. It is also called spinal anesthesia. Pain medicine is injected around your spinal cord to control pain from surgery or labor and delivery. IA can also be used to control long-term pain from illnesses, such as cancer.
How will happen during an IA injection?
Your healthcare provider may give you a single injection of IA if you need pain relief for a short period of time. He or she will use a needle and insert medicine into the area around your spine. He or she may insert a catheter (tube) that will remain in place if you need pain controlled over a longer period of time. This will allow you to have pain relief as you need it.
What should I expect after an IA injection?
A headache is common after IA. The following can help you manage the pain:
- Rest as needed. Lie down until your headache is better.
- Drink more liquids. You may need to drink more liquids for the first 12 to 24 hours following your procedure. This may help decrease your risk for a headache. Liquids containing caffeine may also decrease the pain. Do not drink alcohol. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
What are the risks of spinal anesthesia?
Your blood pressure or breathing may become too slow. You may have nausea or itching skin. You might have trouble urinating. You could have bleeding, swelling, or a leakage of spinal fluid around the catheter or shot area. Rarely, you could get an infection in your head or spine.
