The first thing to do before a puncture biopsy is to understand the purpose of this puncture and the risks that may be involved, and to eliminate any nervousness you may have.
Before doing the puncture biopsy the patient should keep an empty stomach, because the content of fat in the substance drawn out on an empty stomach is lower, which can make the test results more accurate. Before the operation, you need to do a good job of disinfection, anesthesia, and choose a good angle of the puncture needle. At the same time, it is important to pay attention to the appearance of the shape and color of the extracted material.
When doing puncture biopsy, it is necessary to avoid the patient’s large blood vessels and superficial veins, because it can effectively prevent the puncture needle from stabbing the blood vessels and causing local bleeding. For patients with supraclavicular lymph node puncture, it is important to avoid puncturing too deeply to prevent puncturing the pleura of the apical lungs leading to pneumothorax.
After the puncture biopsy, the patient should be compressed for about half an hour to prevent bleeding from the wound site. In addition, patients with inflammation can be treated with anti-inflammatory drugs such as amoxicillin capsules under the guidance of the doctor to prevent postoperative wound infection.
