Straight entry method: can choose to puncture in the thoracic 8, 9, 10, 11 or lumbar 3, 4 intervertebral space. The method is the same as that of lumbar puncture. When the needle tip reaches the ligamentum flavum, remove the needle core and attach a 5ml syringe, which sucks 3 to 4ml of saline and 0.5ml of air bubbles. Push the puncture needle a little bit and squeeze the needle plug. Once the ligamentum flavum enters the dural cavity, there is no resistance, and the air bubbles in the syringe can push the saline into the dural cavity without being compressed. Adjust the direction of the bevel of the puncture needle tip tube toward the head, and insert the epidural catheter into the needle.
