Using Random Allocation Software, random permuted blocks of different sizes 4 or 6, each block containing an equal number of subjects from each group, are designed and a unique identification code is assigned to each block. In this manner, after completion of a block, an equal number of subjects will be enrolled in each group. While referring to the doctor, one of the envelopes is randomly selected and according to the order of its contents, each patient is assigned to one of the groups, Blinding description: The data analyst will not know which group is A or B. 3 Turactomy and pulmonary resections or lung decoration (For empyema treatment). Intervention 1: In the intervention group, 50 cc's of blood will be taken from the patients two days before the surgery and about 5 cc's of autologous fibrin glue will be processed and sprayed on the damaged surfaces of the lung parenchyma in the final stage of the surgery. Intervention 2: Control group: Surgery is performed routinely. No - There is not a plan to make this available Justification or reason for not sharing IPD is There is no further information
