Insights

Wheezing is common in preterm infants. This review covers its causes, prevalence, and management in children born prematurely, with or without a history of bronchopulmonary dysplasia.

Area of Science:

  • Pediatric Pulmonology
  • Neonatology
  • Respiratory Medicine

Background:

  • Wheezing is a frequent respiratory symptom in infants and children.
  • Preterm birth is a significant risk factor for developing wheezing phenotypes.
  • Bronchopulmonary dysplasia (BPD) is a chronic lung disease that often complicates the course of preterm infants, increasing the risk of wheezing.

Purpose of the Study:

  • To provide a comprehensive review of wheezing in preterm children.
  • To elucidate the underlying mechanisms contributing to wheezing in this population.
  • To discuss the epidemiology and current treatment strategies for wheezing in preterm children, considering those with and without a history of BPD.

Main Methods:

  • Literature review of relevant studies on wheezing in preterm infants and children.
  • Synthesis of information regarding the pathophysiology of wheezing.
  • Analysis of epidemiological data and treatment outcomes.

Main Results:

  • Wheezing in preterm children results from complex interactions between airway inflammation, structural abnormalities, and altered immune responses.
  • Epidemiological data indicate a higher prevalence of persistent wheezing in preterm survivors, particularly those with BPD.
  • Treatment approaches are often tailored to the underlying mechanisms and may include bronchodilators, anti-inflammatory agents, and supportive care.

Conclusions:

  • Wheezing represents a significant burden of disease in preterm-born children.
  • Understanding the mechanisms and epidemiology is crucial for effective management.
  • Multifaceted treatment strategies are necessary to improve respiratory outcomes in preterm children experiencing wheezing, especially those with BPD.

Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

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...

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

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...
