KEY POINTS: Evidence at whole animal, organ-system, and cellular and molecular levels suggests that afferent volume feedback is critical for establishment of adequate ventilation at birth. Due to the irreversible nature of vagal ablation studies to date, it was difficult to quantify the roles of afferent volume input, arousal and changes in blood gas tensions on neonatal respiratory control. During reversible perineural vagal block, profound apneas, and hypoxemia and hypercarbia were observed necessitating termination of perineural blockade...

A preterm neonate born at 27 weeks, with a birth weight of 555 g, was on continuous positive airway pressure (CPAP) for apnoea of prematurity and initially received total parenteral nutrition (TPN) through the umbilical venous catheter. Peripherally inserted central catheter (PICC) was inserted in the left basilica vein on day 8 to continue TPN. The baby developed respiratory distress with persistent hypoxia after TPN was initiated through the PICC line. The baby required mechanical ventilation due to worsening of respiratory distress, and chest X-ray, as well as ultrasound conducted 12 hours, postinfusion of TPN revealed right-sided pleural effusion...

Retinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD) are diseases that occur only in preterm infants. The etiology of these disorders is multifactorial; however, it is believed that some of the factors in children presenting with BPD affect both the initiation and severity of ROP. The aim of the study was to evaluate the degree of clinical severity of ROP in infants with BPD compared to those without BPD. Methodology: Infants were divided into two groups: the BPD+ study group and BPD- control group...

Early prediction of bronchopulmonary dysplasia (BPD) may facilitate tailored management for neonates at risk. We investigated whether easily accessible flow data from a mechanical ventilator can predict BPD in neonates born extremely premature (EP). In a prospective population-based study of EP-born neonates, flow data were obtained from the ventilator during the first 48 h of life. Data were logged for >10 min and then converted to flow-volume loops using custom-made software. Tidal breathing parameters were calculated and averaged from ≥200 breath cycles, and data were compared between those who later developed moderate/severe and no/mild BPD...
