Epidural catheterisation technique
1. Open pack using sterile technique.
2. Remove plastic tip protector and examine needle body and tip in order to confirm its integrity.
3. Remove stylet of epidural needle then place it again to confirm smooth movement.
4. Prepare puncture area for the procedure according to standard aseptic technique and apply local anesthesia.
5. Determine a puncture area (point) according to accepted procedure. When determining distance between puncture area and epidural space, you can use cm markings on the epidural needle. These markings can be in the form of a single thin line or 1cm long heavy lines.
6. Start the puncture with the epidural needle. Continue the procedure with standard Loss of Resistance technique or hanging drop technique and confirm reaching to the epidural space.
7. If the use of Epidural Catheter is intended, advance catheter through epidural needle to the extent that the procedure indicates. During this process pay attention to the cm markings on the catheter. After placement of the catheter at desired length, pull back epidural needle while maintaining catheter position within epidural space.
IMPORTANT: Do not pull back catheter for any reason during the process of passing it through Epidural Needle. In cases when pulling back epidural catheter is inevitable then withdraw epidural needle first, then remove the catheter. Otherwise there is a risk of cutting the epidural catheter by the epidural needle bevel.
8. Complete Epidural application.
9. Dispose Epidural needle according to medical waste regulations.
