There are two prices for pleural effusion drainage depending on the material used. One is the ordinary pleural effusion drainage tube with 26-30 gauge, the thickness is about as thick as the pinky finger, and the pleural drainage is about 500 yuan. Because the cost of this closed drainage procedure is 340 yuan, the price of a water seal bottle to strengthen the drainage tube, plus the cost of anesthesia is about 500 yuan. The advantage is that it is less invasive and easier to operate, but the disadvantage is that the puncture kit is disposable and costs 420 yuan and is not covered by medical insurance. Probably the whole closed chest drainage procedure will cost about 1000 RMB.
