percutaneous lung puncture needle injection chemotherapy

Percutaneous lung puncture injection can accurately inject the drug into the cavity, thereby directly killing Mycobacterium tuberculosis in the cavity wall; in addition, due to the erosion effect of the drug solution on the cavity wall, it can promote the softening of the cheese lesions and the necrosis and discharge. . Of course, repeated puncture can also weaken the barrier function of the cavity wall, which is beneficial to the proliferation of granulation tissue and the purification of the cavity.

The following points should be paid attention to in percutaneous lung puncture chemotherapy:

1. The positioning must be accurate, and the puncture needle can be injected only when the puncture needle is in the cavity.

2. A small amount of lidocaine can be injected into the cavity before injection to prevent severe coughing after injection.

3. When injecting the medicine, tell the patient to hold their breath as much as possible.

4. After the injection, it is necessary to confirm again whether there is any medicine in the cavity, and to observe whether there is any pneumothorax.
