Spinal canal decompression

Spinal canal decompression precautions: 1. If the lesion area is severely narrowed and the path is difficult, laminectomy can be performed from the unstenosed segment, and the spinal sac is exposed, and then the operation is gradually extended to the lesion area. 2. If there is bleeding from spinal venous plexus during operation, don't panic, don't blindly block the compression to stop bleeding, so as not to cause damage to the cauda equina and nerve roots. At this time, the bleeding site needs to be attracted with an aspirator. The operator and the assistant cooperate well. The dura mater and the nerve root are pulled away by the dura mater or the nerve root hook to reveal the blood spots. Use double electrocoagulation to stop bleeding or use hemostatic fibers. Or gelatin sponge to squeeze the bleeding point to stop bleeding. 3. Spinal canal enlargement, especially root canal enlargement, requires the surgeon to have proficient skills and precise and correct operation. It is necessary to achieve the purpose of expanding the spinal canal and decompressing the root canal.
