Review"Ventilatory management of asphyxiated infant during hypothermia".
Hypothermia is used for its neuroprotective effect in perinatal asphyxia. Mechanical ventilation is often used as a supportive therapy for severe asphyxiated infants who can present various degrees of respiratory failure. Animal studies demonstrated a protective effect of cooling on the lungs due to reduced ventilatory requirements. Even if actual knowledge on the effects of hypothermia and rewarming on respiratory parameters during mechanical ventilation is limited, nevertheless human studies seem to demonstrate that hypothermia is safe and does not cause significant changes in the level of respiratory supports.

ReviewNew possibilities of prevention of infection in the newborn.
Severe infections represent the main cause of neonatal mortality and morbidity. Strategies of proven effectiveness in reducing the incidence of infection in neonatal intensive care units (NICUs) include hand hygiene practices and prevention of central venous catheter-related bloodstream infections. In recent years, new strategies have been developed to prevent infections in NICU including prevention of neonatal sepsis with lactoferrin, the use of heparin for the prevention of CRBSIs, the judicious use of antibiotics and chemoprophylaxis, prevention of invasive fungal infections with fluconazole, the use of specific anti-staphylococcal immunoglobulins, and the early identification of infants at higher risk of infection with the use of specific markers (mannose-binding lectin). This review will focus on these new strategies and on their role in clinical practice in order to further reduce the incidence of infection in NICU.

ReviewEvidence-based platelet transfusion recommendations in neonates.
Even though for certain varieties of neonatal thrombocytopenia, intravenous immunoglobulin or corticosteroids are recommended as treatments, platelet transfusions represent the only specific therapy currently available for most thrombocytopenic neonates in NICUs. The majority of these NICU platelet transfusions, up to 98% in some recent reports, are given to prevent, rather than to treat, bleeding. The trigger limit of platelet count to prophylactically treat non-bleeding patients is generally arbitrary. ⋯ To increase benefits and safety, new widespread changes in platelet transfusion guidelines are necessary. New transfusion paradigms should not be based on reasoning alone, but on important experimental validation. The neonatologists would better accept them and more closely adhere to.

Clinical TrialUnexpected effect of recruitment procedure on lung volume measured by respiratory inductive plethysmography (RIP) during high frequency oscillatory ventilation (HFOV) in preterm neonates with respiratory distress syndrome (RDS).
In clinical practice, one of the major problems in optimizing recruitment or lung volume during HFOV in preterm infants is the inability to accurately measure direct changes in lung volume at bedside. ⋯ Because RIP cannot differentiate between changes in lung fluid or intrathoracic gas, we hypothesized that as CDP increases and total lung capacity is approached, pulmonary vascular resistance increases as a consequence of the compression of intra-alveolar vessels. This increases right ventricular afterload which, combined with re-establishment of right-to left shunting, results in decreased pulmonary blood flow and then decreased lung volume. Caution should then be used when using high CDP values during the recruitment procedure.

Neonatal and paediatric intensive care are usually provided in distinct units, characterized by highly specialized staffs dedicated either to critically ill newborns (NICUs) or to critically ill children (PICUs). However, such a model may be not suitable or even applicable to all medical organisations or to different local needs. ⋯ Whilst many aspects of modern neonatal care do resemble those routinely used in the paediatric intensive care setting, several clinical issues are unique to each respective sector and cannot be easily translated to the other one. In order to guarantee the best quality of care, NICU doctors and nurses should acquire adequate competence and skills, by means of focused multidisciplinary training programmes, as well as extensive exposure to a wide paediatric case mix.
