Randomized Controlled Trial
The SafeBoosC phase II randomised clinical trial: a treatment guideline for targeted near-infrared-derived cerebral tissue oxygenation versus standard treatment in extremely preterm infants.
Near-infrared spectroscopy-derived regional tissue oxygen saturation of haemoglobin (rStO2) reflects venous oxygen saturation. If cerebral metabolism is stable, rStO2 can be used as an estimate of cerebral oxygen delivery. The SafeBoosC phase II randomised clinical trial hypothesises that the burden of hypo- and hyperoxia can be reduced by the combined use of close monitoring of the cerebral rStO2 and a treatment guideline to correct deviations in rStO2 outside a predefined target range. ⋯ A clinical intervention algorithm based on the main determinants of cerebral perfusion-oxygenation changes during the first hours after birth was generated. The treatment guideline is presented to assist neonatologists in making decisions in relation to cerebral oximetry readings in preterm infants within the SafeBoosC phase II randomised clinical trial. The evidence grades were relatively low and the guideline cannot be recommended outside a research setting.

Retinopathy of prematurity (ROP) was first observed soon after the widespread introduction of oxygen therapy into neonatal care. Early trials suggested that restricting oxygen supplementation could reduce ROP without other consequences, but when oxygen restriction became widespread, increased mortality was observed. ⋯ These results illustrate the importance of randomized trials because, prior to these recent studies, trends in practice based on observational data were favouring lower SpO2. Follow-up data may yet further inform clinical practice.

Higher patient-to-nurse ratios and nursing workload are associated with increased mortality in the adult intensive care unit (ICU). Most neonatal ICUs (NICUs) in the United Kingdom do not meet national staffing recommendations. The impact of staffing on outcomes in the NICU is unknown. ⋯ Nurse-to-patient ratios appear to affect outcomes of neonatal intensive care, but limitations of the existing literature prevent clear conclusions about optimal staffing strategies. Evidence-based standards for staffing could impact public policy and lead to improvements in patient safety and decreased rates of adverse outcomes. More research on this subject, including a standard and valid measure of nursing workload, is urgently needed.

Review Historical Article
The journey towards lung protective respiratory support in preterm neonates.
The aim of this conceptual review is to provide the reader with a broad perspective on progress made in respiratory support of preterm infants over the past five decades. Landmark discoveries are described in their historical context and underlying theories of lung protection are discussed. The review finishes by integrating different approaches and perspectives into a state-of-the-art concept for lung-protective ventilation in this fragile patient population. ⋯ Given the fact that progress made in the last decade has only resulted in minor improvements in mortality and morbidity rates of neonates with respiratory failure, it seems unlikely that further refinements of current technologies will produce giant leaps forward in high-resource countries. It appears that entirely new approaches would be required. In contrast, knowledge and technology transfer of basic respiratory support strategies (e.g. use of oxygen, simple systems to provide continuous positive airway pressure), could have an enormous impact on the prognosis of neonates with respiratory failure in low-resource countries.

Randomized Controlled Trial Comparative Study
Closed versus open endotracheal suctioning in extremely low-birth-weight neonates: a randomized, crossover trial.
Endotracheal suctioning, which is frequently necessary in mechanically ventilated patients, might cause complications, especially in patients with compromised lung function such as extremely low-birth-weight (ELBW) neonates. ⋯ CS was superior to OS on oxygenation values. To prove its overall superiority, further research is required. So, in this group of patients, CS should currently be administered on an individual basis.
