Precautions For Puncture Biopsy Needle

Before performing puncture biopsy needle, it is best to maintain an empty stomach to avoid the high fat content in the extracted substance, which may affect the examination results. In the extracted material, we should pay attention to the appearance, shape, color, etc., the darker the color, the more serious the condition. If the material cannot be removed at the first time, repeat the puncture at the original point of penetration and extract several times in all directions. If bleeding occurs, the operation should be stopped immediately. It should also be noted that the site of puncture should be selected to be relatively easy to fix, and the location of large blood vessels should be avoided.
