Insights

Thoracic musculoskeletal alterations are common in premature infants. These changes are linked to lung conditions like respiratory distress syndrome and bronchopulmonary dysplasia, as well as a low length-to-age ratio.

Area of Science:

  • Pediatrics
  • Musculoskeletal Health
  • Neonatology

Background:

  • Premature infants often experience developmental challenges.
  • Thoracic musculoskeletal alterations can impact respiratory function and overall growth.

Purpose of the Study:

  • To determine the prevalence of thoracic musculoskeletal alterations in premature infants.
  • To identify factors associated with these alterations in the first year of life.

Main Methods:

  • Cross-sectional study of infants born prematurely (birth weight < 2,000 g).
  • Physical examinations by two independent physiotherapists assessed thoracic retractions and shoulder elevation.
  • Univariate and multiple logistic regression analyses identified associated factors.

Main Results:

  • High prevalence of thoracic alterations: 66.9% and 68.6% detected by two physiotherapists (kappa = 0.77).
  • Associated factors included respiratory distress syndrome (OR=3.25), bronchopulmonary dysplasia (OR=11.14), and low length/age ratio (OR=4.57).

Conclusions:

  • Thoracic musculoskeletal alterations are highly prevalent in premature infants.
  • Pulmonary disease and a low length/age ratio are significantly associated with these alterations.

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...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Physical Assessment of the Respiratory Tract II: Inspection

Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.
Chest Configuration
The chest configuration can...

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
