To determine whether serum prealbumin would be useful in identifying adequacy of protein and calorie intake in premature infants, 17 infants between 26 and 33 weeks gestational age were studied throughout hospitalization. Serial anthropometric measurements, nutritional intake, and serum prealbumin concentrations were correlated. When mean intake of calories and protein was lower than 100 kcal/kg/day and less than 2 gm/kg/day, respectively, there was a significant difference in mean prealbumin values, compared with those in infants with a higher intake (P much less than 0.001). For infants with birth weights of 1000 gm or less, prealbumin correlated with protein intake (r = 0.66) and calorie intake (r = 0.64). In these infants, when protein intake exceeded 2 gm/kg/day, prealbumin concentrations increased to values reported for full-term infants in the first months of life. There was no significant correlation between intake of calories or protein and prealbumin values for infants born weighing greater than 1000 gm. Anthropometric measurements did not correlate with protein or calorie intake. We conclude that prealbumin is a sensitive measure of protein and calorie intake in premature infants, and that the definition of adequate nutrition may be different for premature infants of different birth weights and at various postconceptional ages. 相似文献

早产儿脑室周围-脑室内出血研究进展 总被引:3,自引:2,他引:1
脑室周围-脑室内出血(periventricular-intravent-ricular hemorrhage,PVH-IVH)是早产儿常见颅内病变,是导致早产儿死亡和伤残的重要原因之一[1]。既往认为严重神经系统后遗症主要发生于重度颅内出血患者,而轻度出血则预后良好。但近年研究结果表明,即便是那些无明显临床症状的 相似文献

Extremely low birth weight infants are particularly prone to rickets (osteopenia) due to their rapid growth and to deficient intake of calcium and phosphate. In some premature infants suffering from phosphate depletion hypercalcemia syndrome may precede bone demineralisation. Additionally, the adverse effects of calciprivic drugs (phenytoin, phenobarbital, glucocorticoids, furosemide, heparin) contributing to the development of neonatal rickets are discussed. Phosphorus depleted or heparin treated experimental animals develop impairment of mineralisation as manifested by rickets or osteomalacia. Some clinical cases of neonatal rickets are reported and a dosage schedule for parenteral infusion of minerals is given. 相似文献

Measurements of bone turnover markers in premature infants 总被引:2,自引:0,他引:2

We determined the levels of circulating bone turnover markers in preterm infants during the first weeks of life. Twenty premature infants (mean gestational age 27+/-2.2 weeks, mean birth weight 894+/-231 g) hospitalized in the neonatal intensive care unit (NICU) at the Meir General Hospital, Israel, participated in the study. Measurements of bone turnover markers were performed at birth, and every week thereafter for an average follow-up of 11.2+/-0.7 weeks. Bone osteoblastic activity was assessed by measurements of circulating osteocalcin, bone-specific alkaline phosphatase (BSAP) and the C-terminal procollagen peptide (PICP) levels. Bone resorption was assessed by measurements of serum levels of the carboxy-terminal cross-links telopeptide of type I collagen (ICTP). All three markers of osteoblastic activity increased markedly and significantly during the first three weeks of life, and then continued to increase gradually until week 10 (p<0.01). Circulating ICTP levels increased in the first week of life and then decreased gradually throughout the follow-up (p<0.01). The study participants were divided into premature infants born at extremely low birth weight (ELBW: <1000 g, n=12) and very low birth weight (VLBW: 1000-1250 g, n=8). Osteocalcin (in weeks 2-5 of life), PICP (weeks 3-5), and ICTP levels (weeks 2-3) were significantly higher in VLBW preterms. These results suggest increased bone formation in premature infants in the first three months of life. The increased bone turnover in VLBW compared to ELBW premature infants may be the result of a generally higher morbidity in ELBW preterm infants in early stages of life. 相似文献

Extrauterine growth retardation in premature infants in Shanghai: a multicenter retrospective review
Hong Mei Shan Wei Cai Yun Cao Bing Hua Fang Yi Feng 《European journal of pediatrics》2009,168(9):1055-1059
Intrauterine growth retardation (IUGR) represents the degree of body growth and development decided by genes and by placental
function. Extrauterine growth retardation/restriction (EUGR) refers to severe nutritional deficits during the first weeks
of life that result in growth that is less than expected based on intrauterine growth rates (growth values ≤10th percentile
of intrauterine growth expected in accordance with the estimated gestational age). The deficits affect not only weight but
also head circumference and height. As is well known, a nutrition support team (NST) is a multidisciplinary team comprised
of physicians, nurses, dietitians, pharmacists, social workers, and medical technologists who provide nutritional management.
In this study, we review 2,015 premature infants (1,209 boys and 806 girls) from four hospitals in the Shanghai area from
January 1, 2003 to December 31, 2006, two of which had NSTs. The overall incidence of EUGR was 56.8% assessed by weight, while
the incidence of IUGR was 26.1%. Higher incidence of EUGR was associated with lower birth weight, but higher gestational age.
There was a significant relationship between EUGR incidence and NST availability (χ
2 = 60.630, p < 0.001), though there was no similar finding for IUGR incidence. The incidence of EUGR was 44% in NST hospitals and 62.6%
in non-NST hospitals. According to logistic regression, the following five factors were related to EUGR: male gender, gestational
age at birth, birth weight, length of hospital stay, and NST availability. NSTs reduced the risk of EUGR by a magnitude of
0.47. EUGR remains a serious problem in premature infants in Shanghai, but NSTs can reduce EUGR incidence. 相似文献
