Insights

Preterm infants undergoing intubation may face long-term voice problems, known as dysphonia. Female gender, low birth weight, and multiple intubations are associated with increased risk.

Area of Science:

  • Neonatal care
  • Pediatric audiology
  • Laryngology

Background:

  • Endotracheal intubation is crucial for very preterm infants but poses a risk for dysphonia.
  • Preterm children may experience voice disorders later in life due to intubation.

Purpose of the Study:

  • To review existing evidence on long-term voice outcomes in preterm children.
  • To identify risk factors associated with dysphonia in this population.

Main Methods:

  • Systematic review of studies on preterm infants and voice outcomes.
  • Analysis of factors linked to dysphonia in published case studies and series.

Main Results:

  • Limited studies exist, with three larger ones reporting on dysphonia in preterm children.
  • Risk factors for poor voice outcomes include female gender, low birth weight (<1,000 g), and early gestation (<27 weeks).
  • Surgical interventions, emergency/multiple intubations, laryngeal pathology, and supraglottic compression are linked to adverse voice outcomes.

Conclusions:

  • Dysphonia is an emerging long-term complication of preterm birth.
  • More research is needed to confirm risk factors and guide future voice treatment studies.

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

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 IV: Auscultation

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through...

Language Development01:22

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
