enkephalin--leucine-2-alanine and Postoperative-Complications

To study influence parapancreatic microirrigation on morphological and functional condition of a pancreas and transformations of enzymatic activity of blood serum and enzymatic activity of lymph of a chest lymphatic channel after an operative trauma of a duodenum.. Research is executed on 140 not purebred dogs which have been divided into six groups and united in two series. In the first series (30 dogs) were studied changes pancreatic exosecretion in the postoperative period of resection of duodenum (group 1.1), in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 1.2) and after resection of duodenum with application parapancreatic microirrigation (group 1.3). In the second series (110 dogs) were studied frequency of development of acute pancreatitis, enzymatic activity of blood serum and enzymatic activity of lymph of thoracal lymphatic duct after resection of duodenum (group 2.1) and in the postoperative period of resection of duodenum with preliminary infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain (group 2.2) and after resection of duodenum with application parapancreatic microirrigation (group 2.3).. Application parapancreatic microirrigation does not lead to oppression pancreatic exosecretion at the first o'clock after duodenotomy, and substantially reduces the pancreatic hypersecretion observed in the postoperative period of resection of a duodenum. In addition, application parapancreatic microirrigation reduces frequency of development of acute pancreatitis and promotes less expressed increase enzymatic activity of blood serum and enzymatic activity of lymph thoracal lymphatic duct at development of the given complication after operational trauma of duodenum in comparison with resection of duodenum and after a resection of a duodenum executed against infiltration of a parapancreatic tissue of 0.5% by a solution of Novocain.

The paper analyzes whether the national synthetic leukenkephalin analogue dalargin can be used in the prevention and treatment of postoperative polyorgan deficiency. Dalargin has been experimentally demonstrated to be effective in preventing impairments in transcapillary fluid exchange, by stopping the development of pulmonary edema. The use of the drug in the intra- and postoperative period in patients undergone cardiac surgery during general assisted circulation reduced the incidence substantially and decreased the severity of respiratory distress syndrome. The experimental and clinical findings suggest that dalargin has pulmono-, hepato-, and pancreatoprotective properties. Thus, dalargin should be used in the multimodality intensive care of postoperative polyorgan deficiency.

In the experiment on 200 rats with acute pancreatitis, it was revealed that in administration of dalargin at a dose of 10 mg/kg of the mass, the activity of xanthinoxidase and lipid peroxidation in the pancreas was suppressed, at the same time, the activity of trypsin, amylase and transamidinase in the blood serum decreased. In 48 patients, who underwent the intravenous administration of dalargin at a dose of 50 mg/kg at operation on the pancreas and after it, the incidence of acute postoperative pancreatitis development decreased 4.16-fold when compared to the use of protease inhibitors, and 2.4-fold when compared to the use of fluorouracil.
