穿刺引流术（Puncture and drainage） The third chapter is puncture drainage I. overview Puncture drainage called percutaneous drainage (percutaneous puncture drainage technique), namely in the imaging equipment under the guidance and catheter drainage by puncture needle and other equipment, pipelines, on the human body cavity or tissues for pathological effusion, hematoma, abscess, pancreatic juice, bile or urine fluid deposition of aspiration in order to decompression and drainage, and the purpose of treatment. Percutaneous puncture drainage is usually used in all parts of the body of abscess, cyst, serous cavity effusion, bile duct or urinary tract obstruction, intracranial hematoma puncture and drainage. In cytology, to extract bacteriological and biochemical detection, make differential diagnosis and guide treatment at the same time, can also through the drainage catheter drainage in the treatment of local inflammation, and achieve decompression, anti-inflammatory and other effects. Two, equipment and drugs (I) puncture needle Each type of puncture needle and trocar for 17~ and 23G are used. The puncture needle of 20~ 23G is mainly used to puncture the lumen, such as the bile duct or the renal pelvis. After entering the lumen, the 0.018 inch fine guide wire is introduced, then gradually extended the puncture path and finally placed into the drain tube. The fine needle can be punctured repeatedly when it is difficult to penetrate the small lumen and important organs because of its slight trauma. Thick needle repeated puncture, especially to liver, kidney and other organs that can move with the breath, may cause severe cutting injury. For larger lesions, easy positioning and superficial lesions such as empyema, giant renal cyst, urinary retention, urinary bladder is available huge thick needle (Figure 10-1) through one-time in place, and then directly into the catheter or the 0.035 -0.038 inch guide wire into the drainage tube.
