Routinely check three major routine, clotting time, preoperative three, ECG. Preoperatively, ceftriaxone 2.0 + saline 100 ml was given intravenously to ensure intraoperative antibiotic concentration in the body and prevent infection. The patient was given an open upper limb vein, walked into the operating room in a prone position with a soft pillow under the abdomen. x-ray surveillance was used to locate the inner edge of the left small joint of L4/5 and marked as the puncture point. Until the tip of the needle reaches the posterior edge of the intervertebral space, inject 0.5 ml of iodophoresis, showing that the contrast agent is evenly distributed within the intervertebral disc, confirming that the tip of the needle is located within the herniation. RF needle core to advance 5 mm, test impedance of 250 ohms, high-frequency test sensation, the patient no discomfort, low-frequency test movement, no muscle bundle beating, the start of radiofrequency thermal coagulation, the process is as follows: RF finished slowly inject 10ml 40ug/ml O3, pushing the injection felt little resistance within the disc, the patient no significant discomfort. Slowly retreat the needle to the lateral saphenous fossa, retract without blood and cerebrospinal fluid, inject 5ml of anti-inflammatory and analgesic solution (formula: Micropol 1mg, 2% lidocaine 2ml, Depo-Provera 7mg), exit the needle, aseptic dressing cover the puncture point, observe for 15 minutes, the patient has no discomfort, flat car sent back to the ward. Postoperative routine dehydration and anti-infection treatment for 3 days.
