What Are The Four Major Punctures in Medicine?

The four major punctures in medicine are: bone puncture, lumbar puncture, abdominal puncture, and thoracic puncture.

Puncture is a commonly used surgical term in medicine. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion and catheter placement for angiography.

No matter what kind of "piercing" it is, it must pierce the skin and the corresponding tissues in the deep surface, which is "injury". That is, puncture is a "destructive inspection" item. If the doctor believes that for the purpose of inspection, it is necessary to directly examine the deep tissue in the body through puncture, so as to obtain an intuitive understanding of the disease and facilitate the diagnosis and treatment of the disease, then the puncture examination is "needed".
