<s>[INST] hi, my father is suffering from Double Pnemonia with plural effusion. He was hospitalized from 10-12 days. Now hes recover from pnemonia and when hes hospitalized Approx 250 ML Fluid remove from his lungs. Now again hes suffering from Plural effusion. Please suggest what to do now? [/INST] Hi thanks for contacting Chat Doctor .... Because of pneumonia you had oxidative pleural effusion...250 ml fluid is very much high amount... Now again you have pleural effusion.... For that first sputum is sent for microscopic examination... Sputum culture also need to be done....ADA estimation also done along with sputum for Tuberculosis detection. If TB present AKT need to be given... If TB not presents again pneumonia has to be treated according to culture report.... If therapeutic pleural effusion fluid removed then send it for cytological examination.... Consult pulmonologist or physician for your condition... Take care. Chat Doctor.  </s>
