“…Many infants on noninvasive support are placed in the prone position as previous studies have demonstrated that this reduces thoraco-abdominal asynchrony, improves oxygenation and increases functional residual capacity (5,7,24). Our study also shows an increase in EELV when switching from supine to prone position but adds important information on its regional distributions.…”

“…To make these transitions successful, infants should be able to maintain an optimal EELV and normal ventilation during nCPAP. Placing infants in prone position might facilitate this transition to nCPAP as this posture seems to increase EELV and improve respiratory mechanics (5)(6)(7)(8).…”

“…To minimize the invasiveness of this study, pulmonary function measurements were made in the body position also determined by the clinical care provider. As previous data in preterm infants prior to discharge have shown that respiratory mechanics are not affected by body position, 25 it is unlikely that this is a contributing confounder.…”

Objective: Bronchopulmonary dysplasia (BPD) in preterm infants is associated with impaired alveolar growth, inflammation and airway hyperreactivity. In animal models of BPD, inhaled nitric oxide (NO) improves alveolar growth and inhibits airway smooth muscle proliferation. This study was designed to assess the effect of inhaled NO on resistance and compliance in ventilated preterm infants with evolving BPD.Study Design: Expiratory resistance and compliance of the respiratory system were measured in 71 ventilated preterm infants, p32 weeks gestation, randomized to NO (n ¼ 34) versus placebo (n ¼ 37) for X24 days at 7 to 21 days of life.Result: At baseline expiratory resistance (231±71 versus 215±76 cm H 2 O l À1 s À1) and compliance (0.49±0.14 versus 0.53±0.13 ml cm H 2 O À1 kg À1 ) were comparable between placebo and NO groups, respectively. There was no effect of NO on expiratory resistance or compliance at 1 h, 1 week or 2 weeks of study gas administration.Conclusion: NO had no short-or medium-term effect on expiratory resistance or compliance in ventilated preterm infants.

“…In other studies, the indicator that most improved oxygenation and oxygen saturation and reduced hypoxia was the prone position, thus promoting its use in newborns 6,[18][19][20][21] . Our results show that the elastic chest band had a strong influence on oxygen saturation.…”

| Background: Preterm newborns have higher thoracic compliance, providing less stability to the different forces of distortion imposed on the rib cage, leading to instability of the chest. Adequate body position may reduce this instability and facilitate respiratory work. Objective: To assess the oxygen saturation response of preterm newborns receiving rib cage stabilization with an elastic band in two body positions. Method: A clinical, prospective, randomized crossover study was conducted, including sixteen newborns with a gestational age of 31 to 35 weeks (mean 32.8 weeks) at a tertiary care facility, who did not receive supplemental oxygen. The infants were placed in a sequence of prone and supine positions with and without chest stabilization with an elastic band. Respiratory rate, heart rate, and oxygen saturation were measured at 10-minute intervals, corresponding to 7 samplings of 60 minutes. Data collection was interrupted when oxygen saturation was less than 90%. Results: The mean gestational age of the infants was 32.8±1.5 weeks and the mean birth weight was 1,789±255g. Better values for the variables studied were observed in the supine position with an elastic chest band compared to the supine position without the band. The positions using an elastic band resulted in lower mean respiratory rate and heart rate and higher oxygen saturation. Conclusion: The use of an elastic chest band improves respiratory indicators such as oxygen saturation.Keywords: respiratory mechanics; preterm newborn; supine position; prone position; movement.

Effect of Posture on Oxygenation, Lung Volume, and Respiratory Mechanics in Premature Infants Studied Before Discharge

Abstract: Superior oxygenation in the prone posture in oxygen-dependent premature infants studied before discharge could be explained by higher lung volumes.
