Insights

The severity of bronchopulmonary dysplasia (BPD) significantly impacts preterm infants feeding abilities. Severe BPD correlates with poorer suck-swallow-respiration coordination, reduced sucking endurance, and overall impaired feeding performance.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pulmonology
  • Developmental Pediatrics

Background:

  • Preterm infants with bronchopulmonary dysplasia (BPD) frequently experience feeding challenges.
  • Sucking difficulties are a common concern in infants diagnosed with BPD.

Purpose of the Study:

  • To investigate the relationship between the severity of bronchopulmonary dysplasia (BPD) and feeding capabilities in preterm infants.
  • To assess how BPD severity influences suck-swallow-respiration coordination, sucking endurance, and feeding performance.

Main Methods:

  • Twenty very low birth weight infants were evaluated at 40 weeks' postmenstrual age.
  • Infants were categorized into three groups based on BPD severity: none, BPD without home oxygen, and BPD with home oxygen.
  • Feeding parameters including sucking pressure, frequency, duration, swallows, deglutition apnea, and respiratory rate were measured during bottle-feeding.

Main Results:

  • Infants with severe BPD exhibited the lowest sucking pressure, frequency, and burst duration.
  • Severe BPD was associated with reduced feeding efficiency, fewer swallows per feeding burst, and prolonged deglutition apnea.
  • These infants also showed the highest respiratory rates and the most significant decrease in oxygen saturation during feeding.

Conclusions:

  • Feeding difficulties in preterm infants are directly related to the severity of bronchopulmonary dysplasia.
  • Infants with BPD demonstrate impaired feeding coordination, reduced endurance, and diminished overall feeding performance.

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...
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...

Mechanical Ventilation III: Noninvasive Ventilation

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Mechanical Ventilation I: Indication and Settings

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
