ReviewStrategies to accelerate weaning from respiratory support.
Because mechanical ventilation is associated with severe complications in premature infants, it is important to limit its duration as much as possible. This can be accomplished by using strategies that preserve spontaneous respiration such as patient triggered and volume target ventilation. The use of respiratory stimulants and nasal CPAP or nasal IPPV after extubation are also effective and improve extubation success. A short course of systemic steroids can also expedite weaning and extubation.

ReviewGlobal perfusion assessment and tissue oxygen saturation in preterm infants: where are we?
Near infrared spectroscopy (NIRS) monitoring is a new challenge for clinicians who deal with early detection of dangerous hypoperfusion in the brain, as well as in splanchnic and renal districts in critically ill preterm infants. Previous studies performed on infants and children with congenital heart disease, demonstrated the efficacy of this non-invasive method in managing hypoperfusive states pre, post and during cardiac surgery. ⋯ Early identification of silent hypoperfusion has made NIRS use in preterm infants very interesting for neonatologists, especially where other techniques have failed. In this work, literature on this topic has been carefully examined, particularly the "two site NIRS" use in preterm infants, to evaluate how regional splanchnic oxygen saturation changes, both in physiological events, such as enteral feeding and in hemodynamic disorders, that occur in patients with significant patent ductus and in hypoperfusive states that lead to necrotizing enterocolitis.

Lung ultrasound (LUS) has become more and more popular in the first decade of the 21(st) century, both in neonatal and in pediatric age groups. Several papers addressed the usefulness of this procedure mainly because of its possibility to be utilised at the bedside, without risk of irradiation along with simple and immediate interpretations of the images. ⋯ The use of LUS in the clinical field seems to be a reasonable and easy-to-use practice that can be considered an extension of the clinical exam. As a consequence of this feature, LUS, to fully express its potential, must be performed by the clinician in charge of the patient.

Controlled Clinical TrialSerum neutrophil gelatinase-associated lipocalin as a predictor of the development of bronchopulmonary dysplasia in preterm infants.
Bronchopulmonary dysplasia (BPD) is a chronic lung disease mostly occurring in preterm infants. The pathogenesis of BPD involves early inflammation and remodeling of the premature lung. ⋯ High serum levels of NGAL at birth could be an early sensitive marker for BPD in preterm infants, because their levels were physiologically low.
