Insights

Sleep-disordered breathing (SDB) symptoms are common in preterm infants and linked to lower weight. Early identification of risk factors and treatments is crucial for these vulnerable infants.

Area of Science:

  • Pediatric Sleep Medicine
  • Neonatology
  • Developmental Pediatrics

Background:

  • Infants born prematurely face increased risks for sleep-disordered breathing (SDB) compared to full-term infants.
  • SDB can have significant impacts on infant health and development.

Purpose of the Study:

  • To determine the frequency of SDB symptoms in preterm infants.
  • To evaluate the effects of SDB on infant growth.
  • To identify risk factors for SDB in this population to guide prevention and early intervention.

Main Methods:

  • The Louisville pediatric SDB risk survey was used.
  • Primary caretakers of preterm infants at a Neonatal Follow-Up Clinic participated.
  • 173 infants were assessed at a corrected age of 9.13 months.

Main Results:

  • 8.1% of preterm infants snored ≥3 days/week, indicating SDB.
  • Higher SDB symptom scores correlated with lower weight-for-age percentiles (r=-.18, p=.028).
  • Birth weight and size for gestational age did not correlate with SDB risk.

Conclusions:

  • SDB symptoms are present in infants born preterm.
  • SDB in preterm infants is associated with impaired growth.
  • Further research on SDB natural history, risk factors, and treatments is essential.

Respiratory Volumes and Capacities I

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

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...
Alterations in Respiration II01:30

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

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...

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
