Surfactants have been routinely used since 1990 for the treatment of respiratory distress syndrome (RDS). The use of surfactant has coincided with a decrease in mortality in infants due to RDS. This review focuses on clinical aspects of surfactant use. New information, particularly effects of ventilatory styles on surfactant function, is presented.

Clinics in Perinatology, 2001 Surfactant is a metabolically active assembly of phospholipids and surfactant-specific proteins that is essential for normal lung mechanics. The surfactant proteins SP-A and SP-D also have important innate host defense functions. Surfactant metabolism in the developing lung differs from the adult lung by having slower kinetics of secretion with a ...

Coacervation with surfactants: From single-chain surfactants to gemini surfactants
Advances in Colloid and Interface Science, 2017Coacervation is a spontaneous process during which a colloidal dispersion separates into two immiscible liquid phases: a colloid-rich liquid phase in equilibrium with a diluted phase. Coacervation is usually divided into simple coacervation and complex coacervation according to the number of components.

Based on these metabolic studies of surfactant lipids in term lambs, in preterm lambs not treated with surfactant, and in preterm lambs that have been surfactant-treated, the following is a synthesis of the overall metabolism of surfactant. Preterm surfactant-deficient lungs seem to have all the synthetic and secretory pathways for surfactant ...

Paediatric Respiratory Reviews, 2002
An intact and well-functioning pulmonary surfactant system is critical for normal respiration and protection from lung infection. Surfactant is comprised of phospholipids that reduce surface tension and greatly reduce the work of breathing. The other major component consists of surfactant-associated proteins, which optimise the biophysical function of ...

Polymer–surfactant and protein–surfactant interactions
Journal of Colloid and Interface Science, 2005The phase behavior and some physicochemical properties of homopolymers (HP) and hydrophobically modified (HMP) polymers, as well as of polyelectrolytes (PE) and proteins (PR), in the presence of aqueous surfactants, or their mixtures, are discussed.

Many industrial applications that rely on emulsions would benefit from an efficient, rapid method of breaking these emulsions at a specific desired stage. We report that long-chain alkyl amidine compounds can be reversibly transformed into charged surfactants by exposure to an atmosphere of carbon dioxide, thereby stabilizing water/alkane emulsions or,

Surfactants and the environment
International Journal of Cosmetic Science, 1984SynopsisAs a result of their use in detergents and personal products and their subsequent disposal, anionic surfactants may achieve a wide distribution in the environment. It is therefore important to assess the hazard that this use might present to the environment.In order to do this it is necessary to estimate the highest concentrations which are ...

The observed changes in surfactant, the surface-active material which lines the alveoli of mammalian lungs, suggest a secondary effect rather than causation, which is no less important to pulmonary function. In the complex interdependency of many factors permitting adequate gas exchange, it appears that pulmonary surfactant has a significant yet ...
