Exogenous lung surfactants significantly reduce respiratory distress syndrome (RDS) in infants. Natural surfactants show better outcomes than synthetic ones, though synthetic options offer supply advantages.

Area of Science:

  • Neonatal Medicine
  • Pulmonology
  • Pharmacology

Background:

  • Respiratory distress syndrome (RDS) is a major concern in premature infants.
  • Exogenous lung surfactants are crucial for managing neonatal RDS.

Purpose of the Study:

  • To review the pharmacology, clinical efficacy, and cost of exogenous lung surfactants.
  • To compare the effectiveness of natural and synthetic surfactant preparations.

Main Methods:

  • Review of existing literature on exogenous lung surfactants.
  • Analysis of clinical trial data comparing different surfactant types.

Main Results:

  • Exogenous surfactants, particularly natural ones, reduce RDS incidence and complications.
  • Natural surfactants demonstrate superior outcomes in reducing ventilator support, pneumothorax, bronchopulmonary dysplasia, and mortality compared to synthetic surfactants.
  • Rescue therapy within two hours of birth is as effective as prophylaxis for most premature infants.

Conclusions:

  • Exogenous pulmonary surfactants are vital in neonatal care, significantly improving outcomes for infants with RDS.
  • Natural surfactants generally outperform synthetic options in clinical efficacy, despite synthetic agents offering advantages in supply and consistency.
  • Advancements in surfactant therapy and ventilatory care have dramatically improved infant survival rates.

Surface Active Agents01:27

Surface Active Agents

Surfactants, named for their behavior at interfaces, positively adsorb at the interfaces of two phases, reducing interfacial tension. Their versatility as emulsifiers, detergents, and foaming agents stems from this ability. Surfactants, often termed amphiphiles, share the property of amphipathy, with molecules having both hydrophilic and hydrophobic portions. The hydrophilic part is called the head, and the hydrophobic part, including an elongated alkyl substituent, forms the tail.Surfactants...
Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Micelles

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...

Drugs Affecting GI Tract Motility: Other Laxatives

Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...
Surface Tension of Fluid01:22

Surface Tension of Fluid

Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.
Surface tension varies with...
Colloids03:22

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
