Puncture, a commonly used medical operating term, is a diagnostic technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, gas or contrast agents are injected into the body cavity to perform contrast examination, or medicines are injected into the body cavity. The purpose of puncture is to take blood for examination, blood transfusion, fluid infusion and to put in a catheter for angiography.

Puncture drainage is a very common treatment means in clinic, and particularly puncture tube drainage under B ultrasonic guidance or CT guidance is adopted at present. The use of puncture drainage in the clinic is most common in the following 3 conditions or diseases: 1. mainly seen in the infection of pleural effusion or the dyspnea symptom caused by a large amount of pleural effusion, the puncture of the postcostal space is adopted for drainage. 2. In case of liver cirrhosis after hepatitis and increased intra-abdominal pressure caused by a large amount of ascites, abdominal puncture is used to release the ascites so as to relieve the intra-abdominal hypertension symptoms of the patient. 3. The abdominal cavity residual effusion after the abdominal operation such as hepatobiliary, gastrointestinal or appendiceal suppuration and even secondary bacterial infection are mainly seen, and abscess is formed to cause symptoms of chilliness, fever and even blood toxicity. The puncture drainage under the guidance of B-ultrasonic is adopted to drain the pus completely, thereby achieving the purpose of healing and avoiding secondary operation.
