[Lung surfactant changes in acute destructive pancreatitis].
Severe acute pancreatitis (SAP), with mortality rate ranging from 15 to 40 per cent, continues to be a serious challenge to emergency surgeons. Not infrequently, in such cases lesions to the respiratory system develop, with the changes in pulmonary surfactant (PS) occurring during SAP considered as one of the major factors implicated. Alterations in structural phospholipids of PS (lecithin and sphyngomyelin) are assessed under experimental conditions in 26 dogs with modulated SAP at 1, 3, 6, 12 and 24 hours, and the obtained results compared to the ones prior to pancreatitis triggering. The animals are divided up into two groups--untreated and given Sandostatin treatment. In either group a reduction of PS fractions is documented, with a statistically significant lesser reduction of the indicators under study being established in the Sandostatin-treated group by comparison with the untreated one. Modulated SAP in dogs accounts for a significant reduction of the surfactant phospholipid values--lecithin and sphyngomyelin--in bronchoalveolar lavage (BAL).
