ReviewBehavior, pain perception, and the extremely low-birth weight survivor.
This article explores the literature concerning responses to pain of both premature and term-born newborn infants, the evidence for short-term and long-term effects of pain, and behavioral sequelae in individuals who have experienced repeated early pain in neonatal life as they mature. There is no doubt that pain causes stress in babies and this in turn may adversely affect long-term neurodevelopmental outcome. Although there are methods for assessing dimensions of acute reactivity to pain in an experimental setting, there are no very good measures available at the present time that can be used clinically. ⋯ Animal evidence suggests that the neonatal brain is affected differently when exposed to morphine administered in the absence of pain than in the presence of pain. Pain control may be important for many reasons but overuse of morphine or benzodiazepines may have undesirable long-term effects. This is a rapidly evolving area of knowledge of clear relevance to clinical management likely to affect long-term outcomes of high-risk children.

Family factors and social support in the developmental outcomes of very low-birth weight children.
This study used data that were representative of the normative population of all infants born in 1988 and were followed during the first 3 years of life. Large developmental delays and limitations in function were common among children weighing less than 1500 g at birth. Among very low-birth weight infants, minority status and living in a household headed by a single mother further worsen the disadvantages associated with a very low birth weight. ⋯ Single-parent family structure, race and ethnic minority status, and poverty status also are known to impact on kindergarten readiness, so that we expect a delayed impact of these variables on the child. The strength of this article is the use of normative population data to assess the role of birth weight in child outcome. We examined prenatal risk factors for a baby of very low birth weight, traced the manner by which these selective risks are reflected in the composition of very low-birth weight babies, demonstrated how a very low birth weight was fundamental to delays in development, and identified risk factors and potential buffers in this process.
