An epidural is a nerve block to block pain signals
- Patient Positioning
- Most common
- Sit on edge of bed
- Dangle legs
- Chin to chest and curl to arch back
- Hold very still
- Prone positioning is used for catheter insertion for chronic pain nerve block
- Lateral decubitus position can also be used
- Most common
- Increased intracranial pressure
- Platelets <100,000
- Spinal deformities
- Combative/uncooperative patient
- Remove tape
- Pull–> if any resistance is felt STOP
- Inspect that the catheter tip is intact
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.

Today we’re going to be talking about epidurals.
In this lesson, we will talk about what they are used for, how they are placed, removed, and contraindications
Epidurals are used for blocks. This would be in labor, which is probably the first thought for most people. But they also have other uses. They can be used for aggressive manipulation in physical therapy too. They can also be used for injection purposes. This would be for localized pain relief to a painful area. These injections contain local anesthetic and or steroids. This helps with pain relief for things like chronic back pain. Long term pain control is done with an indwelling epidural catheter. This would help give pain relief to people with cancer and other chronic pain management
The administration will occur by someone speciality trained and with great knowledge of the spine. This will be an anesthesiologist or a trained physician. A nurse would only do this if they become a CNA. But you will help with positioning for administration. The epidural is Injected into the epidural space. Easy to remember, right? You can see in this image the epidural space, here. Supplies will include a kit with the epidural catheter, long needle, syringes, sterile gloves, mask, and gown and a lot of tape! Lidocaine is usually injected to help numb the space before they do the full procedure and then of course the analgesia that is used in the epidural so this is like Duramorf.
Ok guys you can see in this picture they have the catheter in place and all the iodine around it. Patient Positioning is so important. We have to make sure they are still and in a good position for insertion. The most common position is going to be having them sit on edge of bed and have them dangle legs. Have them put their chin to chest and curl to really arch the back. We say like an angry cat arching it’s back. This will allow for the spine to be pushed towards anesthesia and just in good positioning. They MUST hold very still. Positionng could also be in lateral so on their side or prone. Prone would be used more so for those that are getting a more permanent block. So those chronic back pain patients.
Contraindications will be hypovolemia, Increased intracranial pressure, low platelets <100,000, spinal deformities, and combative/uncooperative patient. So low volume because the medicine injected can cause low bp so if our volume is already low that will be a problem. These patients are typically given a fluid bolus prophylactically before the epidural. If platelets are low this can cause bleeding into that space so we need over 100,000 platelets, now this is not a hard rule but anesthesia will want to know a current platelet level. Spinal deformities because well the spinal anatomy will be off and damage could occur. And an uncooperative patient just isn’t going to hold still and remember that’s important!
For removable you will remove tape. There is a lot of tape. Next, pull so if any resistance is felt STOP. Then you will inspect that the catheter tip is intact. This is important. You want to ensure the whole thing came out. You will document that it is removed and the catheter tip is intact. This is also helpful to show the patient.
So to summarize. Epidurals treat pain. The patient needs to arch their back and remember to have them hold still. Anesthesia or medically trained doctor will perform this sterile procedure. And ALWAYS make sure the cath tip is intact on removal.
We love you guys! Go out and be your best self today! And as always, Happy Nursing!
