1, small needle knife treatment is quasi-surgery, is invasive treatment, and the physiological location of the neck is important, blood vessels, nerves are also extremely rich. Therefore, the neck needle knife operation is more dangerous, and the patient’s reaction is also stronger. The operator should be familiar with the anatomy of the neck and the implementation of various knife techniques, clarify the lesion site and level, have a correct estimate of the patient’s condition and systemic condition, operate skillfully, master the depth and level of needle stripping, and not too much extensive stripping. Treatment to closely observe the patient’s response, and be prepared to resuscitate in case of accidents. 2.Require strict aseptic operation. Due to the important physiological location of the neck, small needle knife treatment site is sometimes deeper or adjacent to the joint, coupled with some treatment is often supplemented with hormone closure, prone to infection, once the consequences of infection will be very serious. There have been clinical reports of deep abscesses at the site of surgery due to poor sterilization or improper operation of small needle knife. Therefore, in addition to strict aseptic operation, we should control the dose of hormone use, pay attention to more observation after treatment, and deal with the signs of infection as soon as they appear. 3, requires a clear diagnosis, correct grasp of the indications. If it is appropriate to do adjuvant treatment with small needle therapy, do not do the main treatment. In addition, the treatment of acute patients is not good, the number of treatments for chronic injury patients should not be too much too often, the second interval of at least one week to two weeks or more. 4, the operation should be gentle, fast, accurate. Do not use excessive force or strong rotation of the needle body, so as not to enter the needle too deep or knife needle fracture body. The quality of the knife body should be carefully checked before the operation, and replaced regularly.
