The idea of percutaneous laser disc decompression (hereinafter referred to as PLDD) for the treatment of disc herniation was first proposed by Choy in 1984 in the United States, and the experimental and clinical application of non-endoscopic percutaneous laser lumbar disc decompression was first reported by Choy and Ascher in 1987. In 1989, they reported 420 cases of lumbar disc decompression “resection” using ND:YAG laser, with 3.5 years of follow-up, none of which had serious complications and good results. So what is PLDD? PLDD is the use of laser segmental thermal effect to reduce the compression of the intervertebral disc on the nerve by thermal destruction and vaporization of the disc tissue and then retraction. PLDD has the following characteristics compared with surgery: 1, local anesthesia, small trauma, almost no bleeding. 2.Short operation time. 3, easy to operate, safe and effective, accurate positioning. 4.Easy to operate, safe and effective, accurate positioning. 5.The puncture needle is thin, with little damage and no surgical scar. 6.No scar formation around the vertebral canal after the operation, and the intervention can be repeated several times. 7.No serious complications. 8.Fast postoperative recovery. 9.Multiple vertebrae and intervertebral discs can be treated in the same period. And attaching great importance to the perioperative care of PLDD is an important guarantee for the smooth operation, the reduction of postoperative complications and the improvement of the success rate of the operation. Now the nursing experience is as follows: 1, preoperative 1, psychological care: most patients do PLDD before by a variety of conservative treatment effect is not good, so the lack of confidence in the recovery of the disease and pessimism; coupled with PLDD surgery is a new technology, patients know very little about it, worried about the safety of surgery and the prognosis. (1) health education according to the patient’s literacy and understanding ability, introduce the method, efficacy and safety of PLDD surgery to the patient, introduce the technical level of the attending surgeon, so that the patient will have a sense of trust and security, and eliminate the fear; (2) introduce the patient to each other and communicate with patients with good results in the same disease. (2) Introduce the patients to each other and communicate with patients with good results in the same disease. Because the patients’ personal stories are more convincing to enhance their confidence in overcoming the disease. (3) Appropriate sedation can be given in the evening before the operation to facilitate the patient’s rest and make the patient accept the operation in the best condition. 2. Preoperative preparation: (1) Pain score (VAS) (2) Make sure to ask the patient in detail what kind of disease and treatment he/she has had before surgery. (3) Check the relevant blood test sheets, such as routine blood, bleeding time, clotting time, liver function, etc. (4) Advise the patient to abstain from food and water for 2 h before surgery to avoid aspiration or asphyxia due to intraoperative or postoperative vomiting. (5) Prepare items, semiconductor laser therapy instrument, C-arm X-ray machine or CT, optical fiber, sterile puncture needle, disinfectant solution, dressing kit, cardiac monitor, etc. 2.Intraoperative 1.Observation: mental, vital signs, heat 2.Cooperation 3.Recording: (1) needle (side opening, depth, angle) (2) vital signs (3) laser indices (4) pain score (VAS) 4.Escorting 3.Postoperative 1.Observation of condition Observe whether there is redness, swelling, exudation and other inflammatory reactions at the puncture site; sensory, motor and muscle strength changes in the limbs and trunk, respiration and blood pressure. The situation, pay attention to the occurrence of adverse reactions and complications. 2.Posture care After resting for 1~2h after PLDD, no other discomfort before getting up to walk to the toilet. When getting up for the first time, we must pay attention to the posture and get up slowly, especially for patients with cervical vertigo, and when getting up, we must lie on the side first, then slowly move both lower limbs at the bedside, and then get up and move. When getting up for the first time, the nurse should be at the bedside to guide the patient to the floor. 3. Day 1 after surgery Minimize activities after lumbar spine surgery, rest in bed and wear a lumbar collar for 4 weeks. Wear a collar for 3 weeks after cervical spine surgery, in a supine position with a low pillow as much as possible. Neither cervical nor lumbar spine postoperative diet is restricted, and walking to the bathroom is allowed.
