Insights

Three surfactant preparations, beractant, calfactant, and poractant alfa, showed similar effectiveness in preventing air leak syndromes, death, and bronchopulmonary dysplasia or death in premature infants. Site variations may explain previously observed differences in mortality.

Area of Science:

  • Neonatology
  • Pulmonology
  • Pharmacology

Background:

  • Premature infants often require surfactant replacement therapy to manage respiratory distress syndrome.
  • Different surfactant preparations, including beractant, calfactant, and poractant alfa, are available, with varying clinical use and reported outcomes.
  • Comparative effectiveness data are crucial for guiding therapeutic choices in neonatal intensive care.

Purpose of the Study:

  • To compare the effectiveness of beractant, calfactant, and poractant alfa in premature infants.
  • To evaluate the prevention of air leak syndromes, death, and a composite of bronchopulmonary dysplasia (BPD) or death.
  • To identify potential differences in outcomes among these surfactant preparations.

Main Methods:

  • A comparative effectiveness study involving premature infants from 322 US neonatal intensive care units (2005-2010).
  • Treatment groups included beractant, calfactant, and poractant alfa.
  • Outcomes (air leak syndromes, death, BPD or death) were compared using adjusted analyses considering gestational age, antenatal steroids, discharge year, and small for gestational age status.

Main Results:

  • A total of 51,282 infants received surfactant: 40% beractant, 30% calfactant, 30% poractant alfa.
  • Adjusted analyses revealed similar risks for air leak syndromes across all three surfactant groups.
  • No significant differences were observed in the risk of death or the composite outcome of BPD or death among the surfactant preparations.

Conclusions:

  • Beractant, calfactant, and poractant alfa demonstrate comparable effectiveness in preventing key adverse outcomes in premature infants.
  • Observed differences in mortality between surfactants may be attributed to variations in clinical practice or site-specific factors rather than inherent effectiveness.
  • These findings support the use of any of these three surfactant preparations with similar expectations for preventing major respiratory complications.

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...
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...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...

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...
