ReviewTherapeutic hypothermia in the prevention of hypoxic-ischaemic encephalopathy: new categories to be enrolled.
Therapeutic hypothermia is now the standard of care for brain injury control in term infants with perinatal hypoxic ischemic encephalopathy (HIE). Accumulated evidence shows a reduction in mortality and long-term neurodevelopmental disability at 12-24 months of age, with more favourable effects in the less severe forms of HIE. Only few trials recruited newborns <36 weeks gestational age, or mild-to-moderate encephalopathy with base deficit (BD) <16. The new categories of patients to be enrolled should include (late) preterm infants, neonates with unexpected postnatal collapse, and newborns with stroke. Preterm HIE: Therapeutic hypothermia shows a good safety profile in clinical studies, and no adverse effects were noted in the preterm fetal animal model. Recently, it has been shown that mild hypothermia in preterm newborns with necrotizing enterocolitis (NEC) and multiple organ dysfunction syndrome (MODS) does not increase mortality, bleeding, infection, or need for inotropes in cooled newborns. A pilot study (NCT00620711) is currently recruiting newborns of > 32 but < 36 weeks gestation with standard criteria for HIE. Postnatal Collapse: The postnatal collapse (PNC) is a rare (0.03-0.5/1000 live births) but life-threatening hypoxic-ischemic event. No clinical trials of therapeutic hypothermia have specifically addressed to PNC. Nevertheless, a beneficial effect of brain cooling is expectable, and it has been proposed to include in brain hypothermia trials the infants with PNC fulfilling the entry criteria for HIE. Stroke: Perinatal arterial ischemic stroke is the most common cause of cerebral palsy (CP) in term and near-term newborn. In a systematic review and meta-analysis of animal studies of focal cerebral ischemia, hypothermia reduced the infarct size by 44%. No specific neuroprotective interventions are available for the management of acute perinatal stroke. Hypothermia may decrease seizures in newborns with encephalopathy and a focal infarct, potentially improving the long-term outcome for these infants. ⋯ Future studies of therapeutic hypothermia should include the categories of newborns excluded from the published clinical trials, that is infants <36 weeks gestation, PNC or stroke, or admitted outside of the established 6-hour window, and with encephalopathy not imputable to HIE. New entry criteria will allow significant number of newborns to benefit from the treatment.

ReviewResearch in human resuscitation: what we learn from animals.
It was not until the 18th century that scientists throughout Europe established humane societies to develop resuscitation techniques and to keep registries of successful and unsuccessful cases. Since then, the science and art of cardiopulmonary resuscitation have flourished, multiple international organizations were found, and guidelines are proposed every 5 years in an everlasting attempt to improve the outcome of cardiac arrest victims. The aim of this article is to present the role of animal models in resuscitation research. ⋯ Animal models are used extensively in resuscitation research and possess a central role in the effort towards a better understanding of the underlying mechanisms. However, experimental results should always be cautiously extrapolated in humans.

Review Comparative StudyMore clearly defining the risks of erythrocyte transfusion in the NICU.
Red blood cell (RBC) transfusions convey benefits but they also carry risks. Among NICU patients, some transfusion risks are well defined and their occurrence odds can be estimated and weighed against benefits. However other risks are poorly defined and it is not currently possible to estimate their occurrence adds or weigh these against benefits. ⋯ We advocate always attempt to weigh benefits and risks when ordering a transfusion for a neonatal patient. Certainly some such are life-saving or otherwise clearly beneficial. Perhaps others carry risks unbalanced by meager benefit. Efforts to improve NICU transfusion practice have been proposed and appear to be working to diminish costs and improve outcomes.

ReviewA consistent approach to platelet transfusion in the NICU.
Platelet transfusions are the principal means of treating thrombocytopenia in neonatal intensive care units (NICUs), and are generally used as treatment of thrombocytopenic neonates who have active bleeding and as prophylactic administration in thrombocytopenic neonates who do not have hemorrhage but appear to be at high risk for bleeding. In this article, we summarize the rationale, benefits and risks of platelet transfusions in neonates. We review the importance of choosing the best product available for platelet transfusion, and we emphasize the importance of adopting and adhering to transfusion guidelines.

Communication in the neonatal intensive care unit: a continuous challenge.
Communication between the healthcare team and the parents in Neonatal Intensive Care Unit (NICU) is very important, and may affect both trust in medical team and the health of premature babies. The aim of this study is to confirm that a good relationship with families can be obtained if all the healthcare team adopts a good common communication scheme. ⋯ In NICU, communication between the members of the team and the newborn's parents may be improved by specific tools.
