What is the nerve block technique
Nerve block technology is the specialty of pain doctors from the department of anesthesiology. Through precise puncture of the corresponding damaged nerve roots, a small amount of anti-inflammatory analgesic liquid is injected into the place closest to the nerve roots, so as to repair the damaged nerve to the maximum extent and avoid drug toxicity and side effects.
Nerve blocks, the goal is to repair, to cure pain, not to destroy the nerve as some people think; It has many advantages, such as high efficiency, little damage and good analgesic effect. Just as precision-guided bombs used in modern warfare are compared to conventional bombs.
Nerve block technology has been developed in foreign countries as early as ten years ago. It is a treatment method for disc herniation with diagnosis and treatment technology.
Diagnostic techniques: When multiple disc lesions are present, the mixed signals may interfere with accurate localization. At this time, the nerve block technology can be used to deliver drugs (local anesthetics and anti-inflammatory drugs) directly to the target nerve under the guidance of imaging through a long syringe needle, which can achieve the effect of blocking a certain nerve with high accuracy, and at the same time, the improvement of the patient's symptoms can be seen. It can also help narrow the scope of later surgical treatment and achieve a higher precision of surgical positioning.
Treatment technique: For some patients whose clinical symptoms are not relieved after conservative treatment and whose disc herniation is not too serious after imaging examination, nerve block technique is an ideal treatment method at this stage.
Generally, after nerve block, patients' symptoms can be improved in a short time. After improving local inflammation and scientific functional exercise, the intervertebral disc can be restored to the original position, and the possibility of later surgical treatment can be avoided.
In addition to being a combination of diagnostic and therapeutic techniques, nerve blocks have unique advantages: high precision injection and rapid onset of action. It's not a systemic drug like a shot or a pill, and it's slow to work.
