Insights

Respiratory events in preterm infants before hospital discharge impact later development. Increased time with respiratory events at term predicted lower language and motor scores at 6 months corrected age.

Area of Science:

  • Neonatal development
  • Respiratory physiology in infants

Background:

  • Preterm infants often experience respiratory events.
  • Understanding the long-term impact of these events is crucial for developmental outcomes.

Purpose of the Study:

  • To investigate the association between respiratory events and developmental outcomes in preterm infants.
  • To identify predictors of developmental outcomes at 6 months corrected age.

Main Methods:

  • Studied preterm infants (28-32 weeks gestational age) at multiple time points.
  • Calculated percentage total sleep time (%TST) with respiratory events (apneas, periodic breathing).
  • Used stepwise multiple linear regression to identify significant predictors.

Main Results:

  • %TST with respiratory events at term was a significant predictor of language and motor scores.
  • A higher %TST with respiratory events correlated with lower composite scores on the Bayley Scales of Infant Development.
  • These findings were independent of gestational age, birth weight, and sex.

Conclusions:

  • In stable very preterm infants, time spent with respiratory events at term equivalent age is linked to reduced language and motor outcomes at 6 months corrected age.
  • Early respiratory event management may be important for optimizing neurodevelopmental trajectories.

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...

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...

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...

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...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

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...
