Aims/Background Neonatal respiratory distress syndrome (NRDS) is characterized by progressive aggravation and rapid progression of respiratory distress, with a high incidence rate among premature infants. If left untreated, NRDS results in a poor prognosis. In recent years, various respiratory support modalities have received extensive attention in clinical practice. ⋯ Additionally, both groups demonstrated no significant difference in the incidence of complications such as intraventricular hemorrhage, apnea, necrotizing enterocolitis, and feeding intolerance (p > 0.05). The incidence rates of ventilator-associated lung injury and neonatal bronchopulmonary dysplasia in the nBiPAP group were lower than those in the nSIMV group, with a significant difference (p < 0.05). Conclusion Both nBiPAP and nSIMV have shown good effects in treating NRDS, with nBiPAP showing a significant advantage in reducing the incidence rates of complications such as ventilator-associated lung injury and neonatal bronchopulmonary dysplasia.

This study aimed to compare the effectiveness and safety of neuromuscular blockers, mesenchymal stem cells (MSC), and inhaled pulmonary vasodilators (IV) for acute respiratory distress syndrome through a network meta-analysis of randomized controlled trials (RCTs). ⋯ Neuromuscular blockers significantly reduced the 28-day mortality rate in acute respiratory distress syndrome patients. However, in terms of 90-day mortality, ventilator-free days, oxygenation improvement, IV, MSC, and neuromuscular blockers did not significantly improve.

Determining which patients with ARDS are most likely to benefit from lung recruitment maneuvers is challenging for physicians. The aim of this study was to assess whether the single-breath simplified decremental PEEP maneuver, which evaluates potential lung recruitment, may predict a subject's response to lung recruitment maneuvers, followed by PEEP titration. ⋯ The single-breath maneuver for evaluating lung recruitability predicted, with poor accuracy, the subjects who responded to the lung recruitment maneuver based on [Formula: see text]/[Formula: see text] improvement. Nevertheless, the lung recruitment maneuver, followed by PEEP titration, improved ventilator settings and respiratory mechanics in a majority of subjects.

Role of Alveolar-Arterial Difference in Estimation of Extravascular Lung Water in COVID-19-Related ARDS.
The dominant feature of COVID-19-associated ARDS is gas exchange impairment. Extravascular lung water index is a surrogate for lung edema and reflects the level of alveolocapillary disruption. The primary aim was the prediction of extravascular lung water index by the alveolar-arterial oxygen difference. The secondary aims were in determining the relationship between the extravascular lung water index and other oxygenation parameters, the [Formula: see text], end-tidal oxygen concentration, pulmonary oxygen gradient ([Formula: see text] minus end-tidal oxygen concentration), and [Formula: see text]. ⋯ The alveolar-arterial oxygen difference does not reliably correlate with the extravascular lung water index and the degree of lung edema in COVID-19-associated ARDS.
