Epidural needle operation method

1. The patient takes a lateral decubitus position.

2. The median puncture method (straight entry method) is to penetrate the skin and the supraspinous ligament with a skin needle after the selected puncture of the intervertebral space is locally infiltrated and anesthetized. Insert the epidural needle into the skin, supraspinal ligament and interspinous ligament along the needle hole, and then slowly and continuously advance. When the needle tip passes through the ligamentum flavum, resistance suddenly disappears or negative pressure appears, indicating that the needle tip has entered the dura mater External cavity: No cerebrospinal fluid flow out with syringe withdrawal, and a little saline injection without resistance, which proves that the epidural puncture is successful.

3. The paracentre puncture method takes 1.5cm laterally to the selected intervertebral space as the needle entry point. After local anesthesia, the skin is penetrated with a skin guide needle. The puncture needle is advanced along the guide needle hole to the midline at an angle of 30°~45°, and then slowly and continuously advances. When passing through the interspinous ligament and ligamentum flavum, the resistance suddenly disappears or negative pressure appears Phenomenon, there is no cerebrospinal fluid outflow with the syringe, and a little saline is injected without resistance, which proves that the epidural puncture is successful.

4. Before inserting the catheter, check whether the catheter is unobstructed, whether there are cracks or defects. Insert the catheter into the epidural space through the puncture needle. When the catheter is 3~5cm through the needle port, while inserting the catheter with one hand, withdraw the puncture needle with the other hand. After the tip of the catheter has crossed the bevel of the puncture needle, it should be pulled out together with the puncture needle if it needs to be pulled out. The indwelling length of the epidural catheter should be 2~4cm, and it should not be too long to avoid knotting.
