[General proteolytic activity of the blood in patients after an operation].

Changes in the level of general proteolytic activity of blood (GPAB) were studied in 32 patients after operations on lungs and organs of the abdominal cavity. The GPAB was found to elevate in 50% of patients in the postoperative period. Different pulmonary-pleural complications were detected only in this group of patients. In patients who had no elevation of the GPAB after operation no postoperative complications were found. The elevation of the general proteolytic activity of blood in patients creates favourable conditions for the development of postoperative complications. So, being aware of possible elevation of GPAB in patients it is possible to decrease the amount of postoperative complications by means of inactivators of enzymes.
