If no pus drains out of the drainage tube and the flushing fluid becomes clear and the abscess cavity is significantly reduced, the liver abscess has drained cleanly. Liver abscesses can be drained by percutaneous hepatic puncture and flushed under ultrasound or CT guidance, or not flushed, just tube drainage. From the second day or several days after tube drainage, the abscess cavity can be slowly flushed with isotonic saline and antimicrobial drugs can be injected. If there is no pus from the drainage tube, the patient’s general condition improves, the flushing fluid becomes clear, and the pus cavity is significantly reduced, the tube can be removed. With active treatment, good results can often be achieved, and infection is generally less likely to occur after the original disease is dealt with. After drainage of liver abscess, the wound site should be well cleaned and sanitized, and the wound should be disinfected and medication changed regularly as prescribed by the doctor. You should also follow the doctor’s instructions to go to the hospital for regular checkups, and pay attention to observe the condition, and go to the hospital at any time if you feel unwell.
