Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
Pulmonary surfactant is used as a medication to treat and prevent respiratory distress syndrome in newborn babies. [1] Prevention is generally done in babies born at a gestational age of less than 32 weeks. [1] It is given by the endotracheal tube. [1] Onset of effects is rapid. [2] A number of doses may be needed. [2]
It is characterized by symmetric fine granular opacities, air bronchograms. It does not have pleural effusions because the lung dysfunction is not due to excess fluid (as can occur with a non-compressive Cesaerean section), but decreased surfactant, causing the lungs to be inelastic and crumpled. [6]
Surfactant therapy is the medical administration of pulmonary surfactant that is derived from outside of the body. Pulmonary surfactant is a soap-like chemical synthesized by type II alveolar pneumocytes and is of various lipids (80% phospholipids, 5-10% cholesterol, and ∼10% surfactant-associated proteins).
Eat certain foods Certain foods have also been shown to help clear congestion, says Dr. Mercola. “Raw garlic, when chopped or crushed to release its beneficial compounds, can help fight ...
The U.S. Food and Drug Administration is for the first time setting guidelines for levels of lead in processed baby foods such as jarred fruits and vegetables. Part of an effort to reduce exposure ...
The surface increases during inspiration, which consequently opens space for new surfactant molecules to be recruited to the interface. Meanwhile, during expiration the surface area decreases at a rate which is always in excess of the rate at which the surfactant molecules are driven from the interface into the water film.
