In most cases, puncture of lymph nodes does not require hospitalization, but before puncture, it is usually necessary to check the routine blood count and the four coagulation items, and the puncture should be performed under the guidance of color ultrasound to prevent accidental injury to other organs, blood vessels and nerves. After the puncture, it is usually necessary to compress the area for about half an hour and not to drink and eat for a short period of time, and then go home when there is no obvious discomfort and no obvious local pain. In the case of kidney puncture or thoracentesis, hospitalization may be required. Because the kidney puncture may cause bleeding inside the kidney, it is necessary to stay in the hospital for observation to prevent a large hematoma in the perinephric area, which may affect life safety. In contrast, thoracic puncture is due to the tendency to cause hemothorax or pneumothorax after puncture, which requires hospitalization for 1-2 days for observation to see if there are other injuries. In conclusion, the specific hospitalization requirements for punctured lymph nodes require consultation with the treating primary care physician.
