Comparative Study
Dose-response comparisons of five lung surfactant factor (LSF) preparations in an animal model of adult respiratory distress syndrome (ARDS).
1. We have examined the effects of five different lung surfactant factor (LSF) preparations in the rat lung lavage model. In this model repetitive lung lavage leads to lung injury with some similarities to adult respiratory distress syndrome with poor gas exchange and protein leakage into the alveolar spaces. ⋯ The bovine and the Recombinant LSF are superior to both synthetic LSFpreparations.5. In this animal model and under the described specific ventilatory settings, even between bovine LSFpreparations there are detectable differences that are pronounced when compared to synthetic LSFwithout any surfactant proteins. We conclude that the difference between bovine and synthetic LSFpreparations can be overcome by addition of the surfactant protein C.

Pulmonary blastoma is a very rare malignant primary lung neoplasm, especially in the pediatric population. No more than 50 cases have been described in children, with none if these children diagnosed before the age of 1 month. Speculation regarding its congenital nature has been made. Although is has a uniformly poor prognosis, the case presented is that of congenital pulmonary blastoma as a unique cause of fatal respiratory distress in a neonate.

There are a number of important pulmonary complications of acute pancreatitis which make a significant contribution to the morbidity and mortality of the condition. The pathophysiology and management guidelines are given for each and approaches towards better treatment in the future are discussed.

The clinical usefulness of quantitative plasma polymorphonuclear elastase (PMN-elastase) determinations as prognostic markers of adult respiratory distress syndrome (ARDS) in polytraumatized patients was analyzed. PMN-elastase and C-reactive protein (CRP) levels were determined in 55 polytraumatized patients admitted into the Intensive Care Unit. Eight patients developed ARDS and 47 patients did not. ⋯ PMN-elastase levels in ARDS cases reached significantly higher values than in patients who did not develop this syndrome (P < 0.01). We conclude that the increase in plasma PMN-elastase levels can be useful in predicting the development of ARDS in polytraumatized patients, in instituting prophylactic actions and monitoring the course of the disease in these high risk patients. This test is easily adaptable to the routine of any hospital laboratory.

Case Reports[Nitrogen oxide inhalation in acute pulmonary failure].
Two cases of adult respiratory distress syndrome (ARDS) treated successfully with nitric oxide (NO) inhalation are described. One patient had severe sepsis and the other had trauma induced ARDS. The slow entry criteria for extracorporeal membrane oxygenation (ECMO) was fulfilled in both cases. ⋯ Treatment with NO inhalation was without side effects and easy to administer through the ventilator. Both patients survived without sequelae. We suggest that inhalation with NO should be tried before ECMO treatment is considered in severe ARDS.
