Thoracentesis
A patient with advanced colorectal cancer had dyspnoea. Left-sided pleural effusion was diagnosed by X-ray. After preparation of the needle and closed tubing, ultrasonography is used for determining the optimal site of puncture in the lower part of the pleural space. The structures of the mediastinum are visible behind the fluid collection. The rib is palpated, and the puncture site is anaesthetized. The needle is inserted into the pleural space just above the rib, and the fluid is repeatedly aspirated and injected into a plastic bag through the closed tubing. The valve of the tubing is turned to direct the fluid. A total of 2 liters of fluid was removed. Removal of a larger volume is not recommended at a time.
