What is anesthesia and when would you want to get it? There is a difference between anesthesia and analgesia.
Anesthesia means that you will experience a loss of sensation wherever it was injected by a needle into your body. Analgesia means that you will experience a loss of pain wherever it is injected into your body.
Regional anesthesia will affect only a large part of the body. There are two different techniques that they use when inserting it into the areas in your body called central and peripheral techniques.
Central techniques are done by having neuroaxial blocks like epidurals and spinal anesthesia. While the peripheral techniques are divided into both plexus blocks (like brachial plexus blocks) and single nerve blocks.
There are two different ways that it can be given. The first it can be administered is through one single shot.
The second way it can be given is with a catheter. The medicine can be continuously dripped through the tube and it can be altered to come faster and heavier or slower and lighter depending on how much medicine you want coming into your body.
Regional differs from local anesthetics because it blocks nerve to an entire portion of your body while the local drugs just block a specific nerve supply to a much smaller area of your body. Conduction drugs encompass both local and regional techniques.
Where exactly are epidurals inserted and what parts of your body can it affect? There is a spot in your back between the bony spinal canal called the epidural space.
There are two membranes called the dura mater and the arachnoid mater that include the cerebrospinal fluid around the spinal cord. So the spinal anesthesia is injected into the cerebrospinal fluid while the epidural is injected into the other space.
Sometimes these two techniques are confused with each other because they are so similar. A spinal is located just below where you would insert the catheter which is on your lower back.
When you get this medicine injected into your body, then it can affect the lower half of your body and can cause you to be pretty numb in your legs. Depending on how much medicine is injected into your body, you may still have some feeling in your legs and be able to use your muscles down there.
Usually you cannot walk with a catheter inserted into your body because you are too numb. You are able to still feel pressure down there but all of the pain should be gone.
Pregnant women who are giving birth often opt to get one of these types of anesthesias and all women who have to deliver by cesarean section will get an epidural or a spinal. If you get a spinal, then it will only last for a couple of hours whereas an epidural is a continuous drip and can last for an indefinite amount of time.
It is generally used for pain relief and can be used in conjunction with local drugs. A catheter is put into the space where the needle was to keep a continuous drip going but you will almost always have a catheter to help drain your body of all the liquid it is taking in.
This is done because you do not have any feeling and cannot walk to use the bathroom. After you give birth, you are usually not released from the hospital until you have had a bowel movement and are able to show that you can use the bathroom by yourself.
These drugs also help with back pain, chronic pain, and palliation of symptoms in terminal care. Usually when you hear the word epidural, you only think of pregnant women giving birth that get them, but they are a lot more widely used for various other reasons as well.
Since epidurals have been used, the risk of side effects have gone down drastically and it has become a lot safer to use this technique. This drug is used to help you control the pain and can be a safe way to get you through surgeries and births.
