Precautions for thick needle biopsy

Thick needle biopsy is a combination of imaging and pathology. The precautions include the following four points. The first point is that the patient should eat lightly, rest and relax before the biopsy. The second point is that the biopsy is performed under local anesthesia, so the patient should be immobilized, which is conducive to the smooth progress of anesthesia and puncture. The third point, after anesthesia, the patient’s breathing, blood pressure, heart rate, and pulse should be observed to understand the changes in vital signs and determine the possibility of damage to blood vessels and nerves in advance. Fourth, after the puncture, apply local pressure and bandage to find out whether there is any subcutaneous bleeding or exudation.
