Abstract
Respiratory Distress Management with Pulmonary Recruitment in Preterm Newborns, Preliminary Report
Highlights
At birth, the amniotic fluid found in the alveoli must be reabsorbed to allow the exchange of gases
This work aims to determine if the intermittent application of continuous distending pressure in premature infants with moderate respiratory difficulty, at the onset of respiratory difficulty, reduces the need for mechanical ventilation, use of surfactant and the duration of hospitalization
The patients were treated diferently according to the criteria of the attending physician: Group 1: received treatment according to respiratory distress severity, including oxygen, continuous positive nasal airway pressure (CPAP), surfactant and mechanical ventilation
Summary
The amniotic fluid found in the alveoli must be reabsorbed to allow the exchange of gases. In a structurally immature lung that is partially occupied by liquid, with increased alveolar wall thickness due to immaturity, the diffusion of gas is lower These children often have consumption of surfactant, which causes alveolar collapse and ventilatory problems [3,4,5]. Ventilating premature infants with continuous positive pressure prevents the collapse of the airway at the end of exhalation and helps to increase the re absorption of liquid in the airway This improves ventilation, oxygenation, increases pulmonary volume and elasticity, which increases the pressure at the end of exhalation and decreases the resistance of the airways. A randomized controlled study application of 10 seconds of continuous ventilation continuous positive nasal airway pressure (CPAP) versus bag-mask ventilation in premature babies showed reduction in the need for intubation in the first 72 hours, lower duration of respiratory assistance, less use of surfactant and decreased risk of bronchopulmonary dysplasia [8].
