In general, indwelling needles have the potential to run. In current clinical practice, indwelling needles are mainly left in the body to facilitate the establishment of venous channels for the input of drugs into the body. Generally speaking, the needle will not run after it is fixed, but there are times when it is not fixed properly due to laxity in operation, which may cause the needle to run. After placing the needle, if the local movement is too much, it will cause the needle and the body to shift relatively, which will lead to the needle running, so do not make excessive movements on the site where the needle is placed. When a needle run occurs, it is recommended to inform the nurse or doctor who will take care of it.
