Postnatal growth failure of very-low-birthweight (VLBW) infants may result from a complex interaction of genetic and environmental factors, including inadequate nutrition, morbidities affecting nutrient requirements, endocrine abnormalities and treatments. Among VLBW infants, those small for gestational age (SGA) at birth and those with postnatal growth restriction at the time of discharge are at higher risk of later growth failure and long-term consequences. Nutritional intervention with an "aggressive nutrition" during the first weeks of life may be able to minimize the interruption of nutrients that occurs at birth, and reduce as much as possible the incidence of growth restriction at the time of discharge and later. Even though aggressive parenteral and enteral nutrition appear to be effective and safe in VLBW infants, further evaluations of their long-term effect on growth and health consequences are needed. Several studies evaluating the effect of enriched nutrient formulas after hospital discharge on growth and neurodevelopment have produced conflicting results, whereas the potential deleterious long-term effects of prolonged use of high protein and/or of later catch-up growth have been questioned. In contrast, recent data seem to indicate that the use of human milk after hospital discharge could be the most beneficial diet for subsequent health and development.
Conclusion: VLBW infants SGA at birth and those with early postnatal growth restriction are at high risk of later growth failure and long-term consequences. Therefore, the first objective of early nutrition should be to reduce the incidence of growth restriction at the time of discharge. Further studies on VLBW infants to evaluate the safety and beneficial effects of prolonged dietary manipulation during the first year of life are needed. 相似文献

BACKGROUND: Extrauterine growth restriction (EUGR) in low-birthweight (LBW) infants affects their growth and developmental prognoses as well as their incidence of adult diseases. The aim of the present paper was to determine the frequency and contributing factors of EUGR in infants > or =32 weeks of gestational age. METHODS: The subjects consisted of 416 infants from 22 facilities born between February and October 2002, whose gestational age was > or =32 weeks. For EUGR assessment, subjects whose body measurements in the 37-42 week postmenstrual age (PMA) period were below the 10th percentile of the standard normal distribution, were selected. RESULTS: EUGR incidence rates for weight, length, and head circumference were 57%, 49%, and 6%. In appropriate-for-gestational-age infants, a negative correlation was found between number of gestational weeks and EUGR incidence rates for weight, length, and head circumference, but in small-for-gestational-age infants this was true only for head circumference. Lower gestational age and age in days to achieve complete feeding were among the shared factors contributing to EUGR incidence for weight, length, and head circumference. The significant factors for EUGR incidence for weight and length included whether the infant was small for gestational age, whether oxygen was administered at 36 weeks PMA, age in days at which breast-feeding was initiated, and age in days when the infant regained birthweight. CONCLUSIONS: The growth retardation of preterm LBW infants in the neonatal intensive care unit continues to pose challenges. Relevant factors other than gestational age include intrauterine growth restriction, severe chronic lung disease, and poor nutrition. 相似文献

Preterm intrauterine growth restriction (IUGR) is strongly associated with increased mortality and morbidity. In the management of these infants, complications of preterm birth can be amplified by the effect of suboptimal fetal growth. It is important that pregnancies with IUGR are detected before birth, so that delivery can be arranged in a high-risk maternity unit with the appropriate neonatal staff in attendance. The provision of full support for resuscitation and stabilisation of these infants is crucial to the short-term and long-term health of these infants, who have suffered chronic hypoxia and malnutrition in utero. The long term outcome studies of these infants are retrospective and they include SGA infants. The effects of prematurity affect the outcome of IUGR infants. IUGR is associated with cerebral palsy in those delivered more than 32 weeks gestation. Infants less than 32 weeks of gestation may have poor developmental outcome if the head growth is affected, these infants may have associated cognitive and behavioural problems. Children who fail to grow by 2-4 years are at risk of long term growth problems. This paper outlines the acute and long-term management of these infants. 相似文献

Extrauterine growth restriction (EUGR) is a common condition in very low birth weight (VLBW) preterm infants (< or = 1,500 g). Most affected infants have a birth weight that is average for gestational age, but by the time of hospital discharge have a weight that is less than the tenth percentile for corrected gestational age. EUGR is the most frequent morbidity among VLBW survivors at their time of discharge from the hospital. Studies to elucidate the causes of EUGR have been inconclusive. Recent research has found an association between EUGR, developmental outcomes, and long-term morbidity. Low birth weight has also been associated with chronic diseases later in life. These findings emphasize the critical nature of understanding the phenomenon of EUGR and ways it can be prevented. 相似文献

BACKGROUND AND OBJECTIVE: It has been suggested that fetal growth restriction (FGR) is associated with fetal maturation so that, compared with appropriately grown preterm infants, mortality and some neonatal morbidities may be reduced. The evidence for this is conflicting, and severe FGR has been shown to be harmful. In addition excessive growth has also been shown to be associated with poorer outcomes. As preterm infants are often also growth restricted, centiles for birth weights are distorted and may conceal the degree of growth restriction in a given infant. This study investigated whether using estimated fetal weights (EFW) might reveal the effects of hidden FGR. POPULATION AND METHODS: Using a 25-year database of preterm admissions to a single neonatal unit the ORs for mortality and neonatal morbidities for z scores for birth weight above and below the mean were computed and compared with those computed for z scores for EFW. RESULTS: In 7898 infants born at less than 35 weeks' gestation, the OR for mortality was lowest for birth weights between 1 SD and 3 SD above the mean, but was lowest for EFW between -2 SD and 0 SD below the mean. For periventricular haemorrhage, increasing FGR below the mean reduced the OR with both birth weight and EFW. Apparent reductions in OR for septicaemia, chronic lung disease, persistent ductus arteriosus and necrotising enterocolitis with birth weights of >1 SD above the mean were not seen with EFW. FGR of >-3 SD was associated with increased OR for necrotising enterocolitis with both birth weight and EFW. CONCLUSION: Using fetal growth rather than birth weight standards gives a better indication of the incidence and role of FGR in neonatal disease. 相似文献

Protein metabolism in preterm infants with particular reference to intrauterine growth restriction 总被引:1,自引:0,他引:1
de Boo HA Harding JE 《Archives of disease in childhood. Fetal and neonatal edition》2007,92(4):F315-F319
There is growing evidence that neonatal and long-term morbidity in preterm infants, particularly those born before 32 weeks' gestation, can be modified by attained growth rate in the neonatal period. Guidelines for optimal growth and the nutritional intakes, particular of protein, required to achieve this are not well defined. Due to delays in postnatal feeding and a lack of energy stores developed in the last trimester of pregnancy, preterm infants often suffer early postnatal catabolism until feeding is established. There are indications that infants born with intrauterine growth restriction have perturbations in protein metabolism. Therefore, they may have different protein requirements than appropriate for gestational age infants. This review summarises what is known about protein requirements and metabolism in the fetus and preterm infant, with particular emphasis on the distinct requirements of the growth-restricted infant. 相似文献
