Free radicals may be the cause of many neonatal complications, such as chronic lung disease and brain injury. Treatment options for these complications using antioxidants are being evaluated through research. This article begins with a review of the basic science of free radicals. It then discusses neonatal complications potentially caused by free radicals. A brief description of research into potential treatment options is also included.
Pressure-limited, time-cycled ventilation has been the primary mode of ventilation for neonates for several decades. But the realization that volume rather than pressure causes ventilator-induced lung injury has led to the development of new strategies for ventilation. Volume guarantee is a mode of ventilation that automatically adjusts the inspiratory pressure to achieve a set tidal volume according to changes in lung compliance or resistance or the patient's respiratory drive. Volume-guaranteed ventilation delivers a specific, preset volume of gas, and inspiration ends when it has been delivered. This mode of ventilation requires careful attention to the infant and to ventilator settings.
