The aim of the study was to evaluate the influence of glucocorticoids on vital parameters of full-term and preterm lambs from birth to 48 hours of life. Four experimental groups were formed: NDG (normal delivery group - lambs vaginally delivered, n=15, average of 146-day gestation); NDEXG (normal delivery with dexamethasone group - lambs vaginally delivered whose mothers received 16mg of dexamethasone at 141 days of gestation, n=8, average of 143-day gestation); PRE (premature lambs born by cesarean section at 138 days of gestation, n=10) and PREDEX (premature lambs born by cesarean section at 138 days gestation, whose mothers received 16mg of dexamethasone two days before, n=9). Heart and respiratory rates had variations during the observation period, with the highest mean values in the groups of normal deliveries (NDG and NDEXG). Rectal temperature decreased in all groups in the first 60 minutes of life, with the lowest mean values in premature lambs (PRE and PREDEX) and the Apgar score was higher in animals delivered at normal gestational time. Preterm lambs had lower vitality and chance of survival, however, lower mortality rate was observed in offspring of ewes that received dexamethasone two days before surgery.

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

En países en vías de desarrollo como Argentina, la sobrevida de prematuros de peso inferior a 1000 gramos dista mucho de los resultados reportados por países desarrolladas. Controles prenatales deficitarios, recursos técnicos limitados y la saturación de los servicios de Neonatología son en parte responsables de estas diferencias. Una de las situaciones frecuentemente asociada a decisiones éticas en neonatología se produce en torno al prematuro extremo. Las preguntas más difíciles de responder son si existe un límite de peso o edad gestacional por debajo del cual no se deban iniciar o agregar terapéuticas encaminadas a salvar la vida, por considerarlas inútiles para el niño, prolongan sin esperanza la vida, hacen sufrir al paciente y su familia y ocupar una unidad que priva de atención a otro niño con mayores posibilidades de sobrevida. En el presente estudio se elaboró un score de riesgo neonatal constituido por variables que caracterizan a muchas poblaciones de nuestros países latinoamericanos y que fue validado estadísticamente.El score es de rápida y fácil realización. Permite predecir si el prematuro grave es recuperable o no, posibilitando tomar decisiones éticas basadas en una técnica validada, que permite actuar en el mayor beneficio del niño y su familia, al mismo tiempo que se hace un uso más equitativo de los recursos.
