Insights

Preterm birth complications like chronic lung disease and feeding difficulties impact many infants. Early feeding strategies can improve oral feeding achievement and shorten hospital stays for vulnerable newborns.

Area of Science:

  • Neonatal-Perinatal Medicine
  • Pediatric Pulmonology
  • Developmental Pediatrics

Background:

  • Preterm birth rates are rising in the US.
  • Very low-birth-weight infants frequently develop chronic lung disease (CLD) and feeding difficulties.
  • Achieving full oral feeds is challenging for preterm infants, especially those with respiratory support or CLD.

Purpose of the Study:

  • To review strategies for minimizing aerodigestive disorders in preterm infants.
  • To highlight the importance of early oral feeding interventions.

Main Methods:

  • Literature review of current neonatal-perinatal care practices.
  • Analysis of strategies to support feeding in high-risk preterm infants.

Main Results:

  • Over 40% of very low-birth-weight infants develop CLD.
  • Nearly 25% experience feeding difficulties, delaying oral feeds and hospital discharge.
  • Specific interventions can mitigate these challenges.

Conclusions:

  • Supporting nonnutritive sucking is crucial.
  • Infant-directed feeding protocols and sensory-motor stimulation aid oral feeding.
  • Early introduction of oral feeds is a key strategy for improving outcomes in preterm infants.

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...

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...

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...

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:

Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
