Randomized Controlled Trial Comparative Study
Comparing the Effects of Two Different Levels of Hyperoxygenation on Gas Exchange During Open Endotracheal Suctioning: A Randomized Crossover Study.
Endotracheal suctioning is required for mechanically ventilated patients to maintain a patent airway. Studies show that open endotracheal suctioning affects respiratory mechanics and gas exchange. The aim of this study was to compare the effectiveness of hyperoxygenation with FIO2 + 0.20 above baseline and hyperoxygenation with FIO2 1.0 in preventing hypoxemia, and to determine the impact of open endotracheal suctioning on the pulmonary ventilation of critical subjects receiving mechanical ventilatory support. ⋯ In mechanically ventilated adult subjects, hyperoxygenation with FIO2 + 0.20 above baseline prevents hypoxemia. Also, transient changes in pulmonary ventilation with open circuit suctioning were confirmed by volumetric capnography analysis. (Trial registration: ClinicalTrials.gov NCT02440919).

Comparative Study
Economics of Home Monitoring for Apnea in Late Preterm Infants.
Apnea of prematurity affects a small proportion but large absolute number of late preterm infants, with out-patient management variably utilized despite relative clinical equipoise and potential for improved cost-effectiveness. ⋯ Out-patient management of discharge-delaying ABD events in a late preterm and term population was a cost-effective alternative to prolonged in-patient observation.

Volume-targeted ventilation is increasingly used in low birthweight infants because of the potential for reducing volutrauma and avoiding hypocapnea. However, it is not known what level of air leak is acceptable during neonatal volume-targeted ventilation when leak compensation is activated concurrently. ⋯ The PB980 and V500 were the only ventilators to acclimate to all leak scenarios and achieve targeted VT. Further clinical investigation is needed to validate the use of leak compensation during neonatal volume-targeted ventilation.

The population of children receiving long-term mechanical ventilation is growing worldwide, but only limited data exist in Asian regions. The objective of the study was to review the management of these children in Hong Kong over the past 2 decades. ⋯ Our study showed a steady growth in the number of children receiving long-term mechanical ventilation, similar to that in western countries, yet these children have distinct demographic characteristics, underlying diseases, comorbidities, and outcomes. Home care is feasible in the majority of these children despite a lack of in-home nursing care provision. Prolonged survival of these subjects necessitates the enhancement of transitional care to adult service.
