Randomized Controlled Trial Multicenter Study Comparative Study
Platelets for neonatal transfusion - study 2: a randomised controlled trial to compare two different platelet count thresholds for prophylactic platelet transfusion to preterm neonates.
Neonatal thrombocytopenia is a common and important clinical problem in preterm neonates. A trial assessing clinically relevant outcomes in relation to the different platelet count thresholds used to trigger transfusion has never been undertaken in preterm neonates with severe thrombocytopenia. ⋯ This trial will help define optimal platelet transfusion support for severely thrombocytopenic preterm neonates by evaluating the risks and benefits of two different prophylactic neonatal platelet transfusion thresholds.

The brain is vulnerable to injury and dysfunction during transition after birth in neonates. Clinical assessment of the neurological status immediately following birth is difficult, especially during resuscitation. ⋯ Monitoring the brain provides additional information during immediate transition and may help to guide resuscitation. Doppler sonography is technically challenging during resuscitation and is therefore of limited value. NIRS provides continuous monitoring and is feasible even in very-low-birth-weight infants. In the future, an amplitude-integrated encephalogram might give further information on the status of the brain, but before any of these modalities can routinely be recommended during neonatal resuscitation, clinical trials targeting stable brain function parameters are needed.

Drug therapy is a powerful tool for improving neonatal outcome. Despite this, neonatologists still routinely prescribe off-label compounds developed for adults and extrapolate doses from those used for children or adults. Knowledge integration through pharmacokinetic modeling is a method that could improve the current situation. ⋯ In the meanwhile, the fields of clinical pharmacology (e.g. pharmacokinetic/pharmacodynamic modeling and pharmacogenetics) and neonatology (e.g. whole-body cooling and the lower limit of viability) have both matured, resulting in new research topics. However, in order for the modeling and the newly emerging topics to become effective tools, they need to be tailored to the specific characteristics of neonates. Consequently, the field of neonatal pharmacotherapy needs dedicated neonatologists who continue to raise the awareness that off-label practices, eminence-based dosing regimens and the absence of neonatal drug formulations all reflect suboptimal care.

The limits of viability in extremely premature infants are challenging for any neonatologists in developed countries. The neurological development and growth of extremely preterm infants have come to be the emerging issue following the management in the neonatal intensive care unit. ⋯ The perinatal care after 2005 improved the overall survival rate, but not the neurological outcome of preterm survivors at the limit of viability. Neurodevelopmental impairments were associated with extremely premature birth at GA <24 weeks.

Clinical Trial
Low-flow oxygen for positive pressure ventilation of preterm infants in the delivery room.
The recent newborn resuscitation guidelines have recommended that a pulse oximeter and oxygen blender be used to keep oxygen saturation (SpO2) within the target range. However, an oxygen blender and compressed air are not generally available in delivery rooms. ⋯ Low-flow oxygen for PPV via an SIB used in this study should be sufficient for providing oxygen in resuscitation of preterm infants as long as adequate ventilation is evident. This technique is simple and could be useful in a resource-limited setting.
