Insights

Bronchopulmonary dysplasia (BPD) affects nearly half of very low-birthweight infants despite improved perinatal care. Key risk factors include early gestational age, maternal chorioamnionitis, pneumonia, and multiple blood transfusions.

Area of Science:

  • Neonatology
  • Perinatal Medicine
  • Pediatric Pulmonology

Background:

  • Despite advances in perinatal care, the incidence of bronchopulmonary dysplasia (BPD) remains high in very low-birthweight (VLBW) infants.
  • Improving survival rates for VLBW infants necessitates understanding and mitigating BPD risk factors.

Purpose of the Study:

  • To identify perinatal risk factors associated with the development of BPD in neonates weighing ≤ 1500 grams.

Main Methods:

  • A retrospective analysis was conducted on data from neonates born at ≤ 1500 g between 1999 and 2009.
  • Data were collected from the neonatal intensive care unit (NICU) of the Second Affiliated Hospital of Sun Yat-Sen University in Guangzhou, China.

Main Results:

  • The study included 149 preterm infants born at ≤ 1500 g, with a 48.3% incidence of BPD and a 77.8% survival rate at 28 days.
  • Logistic regression identified gestational age ≤ 30 weeks, maternal chorioamnionitis, ventilation-associated pneumonia, and more than three blood transfusions as significant risk factors for BPD.

Conclusions:

  • The study provides clinical evidence for significant perinatal risk factors contributing to BPD in VLBW neonates.
  • Identifying these risk factors can inform further research and clinical strategies to reduce BPD incidence and improve VLBW infant outcomes.

Chronic Obstructive Pulmonary Disease I: Introduction

Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
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...
Factors Affecting Pulmonary Ventilation01:19

Factors Affecting Pulmonary Ventilation

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
