The methods for eliminating pericardial effusion and ascites mainly include the following aspects: First, etiological treatment, which involves treating the underlying causes of pericardial effusion and ascites. For instance, if tuberculosis is the cause, standard anti-tuberculosis treatment should be administered. Once tuberculosis is under control, the ascites and pericardial effusion will naturally resolve. Second, symptomatic treatment, such as the use of diuretic drugs, can reduce the phenomenon of pericardial effusion and ascites in some patients. If there is hypoproteinemia, appropriate supplementation with albumin can effectively improve the effusion. Third, fluid drainage treatment, if the amount of pericardial effusion and ascites is large, puncture and fluid drainage can be performed to alleviate the pericardial effusion and ascites, and at the same time, further investigate the cause of the effusion.
