The effect of nonnutritive sucking during gavage feeding on nutritional outcome and gastrointestinal transit time was evaluated in 18 premature appropriate for gestational age infants whose birth weights were less than or equal to 1,400 g and gestational ages were less than or equal to 30 weeks. Infants were randomized to a treatment (nonnutritive sucking infants received a pacifier for 30 minutes with each feeding, 12 times per day until they reached a weight of 1,500 g, eight times per day thereafter) or control (no pacifier) group. The nine nonnutritive sucking (five girls, four boys) and nine control (five girls, four boys) infants were treated for 14 days. Infants were without medical complications and were fed a single premature formula by intermittent gastric gavage at exactly 120 kcal/kg/d throughout the study period. Weight gain, linear growth, subscapular and triceps skinfold, and arm circumference accretions were assessed weekly. Serum proteins (albumin, prealbumin, retinol-binding protein, and transferrin) were measured weekly. Gastrointestinal transit times were measured weekly using carmine red markers. In contrast to previous studies, these data indicate no apparent effect of nonnutritive sucking on growth outcome, serum proteins, or gastrointestinal transit time in growing, very low birth weight infants when nutrient intake was controlled. In a subgroup of eight boys (four nonnutritive sucking, four control), energy and fat excretions were determined from 72-hour fecal collections and energy expenditure was estimated from six-hour cumulative heart rate measurements. Neither excretion of fat and calories nor estimated energy expenditure was affected significantly by nonnutritive sucking in this subgroup of baby boys. Fat excretion correlated well (r = .987) with energy excretion. 相似文献

The hypothesis of this study was that pharmacologic doses of calcitriol (1,25-dihydroxyvitamin D3) would result in elevated levels of serum osteocalcin, the major noncollagenous bone protein, and calcium in infants of very low birth weight (less than 1500 g). Twenty-four infants of very low birth weight but of the appropriate weight for gestational age were matched in 250-g weight ranges and randomized into calcitriol treatment and control groups on the first day after birth. Treated infants received 4 micrograms/kg of calcitriol intravenously on entry and on the second and third study days. Controls did not receive calcitriol. Four infants from each group were hypocalcemic (serum calcium level, less than 7.0 mg/dL [less than 1.75 mmol/L]) on entry (five to 20 hours after birth) to the study. Seven infants received calcium replacement; data analyses with and without these infants were similar. Of the remaining 17 infants, eight were in the treatment group and nine were in the control group. Calcitriol significantly increased serum calcium and osteocalcin concentrations on days 2, 3, and 4 after birth compared with the control group. None of eight treated infants manifested hypocalcemia after calcitriol vs eight of nine controls. There were no acute changes in heart rate, respiratory rate, systolic blood pressure, or urinary calcium loss nor were there changes at the infusion site, but the diastolic blood pressure increased with treatment. Although high doses of calcitriol may elevate serum calcium concentrations in infants of very low birth weight, we suggest that the long-term or subtle biologic effects of high doses of calcitriol remain to be studied and that its routine use not be recommended at present. 相似文献

Pain is traumatic for preterm infants and can damage their CNS. We wanted to assess whether multisensorial stimulation can be analgesic and whether this effect is only due to oral glucose or sucking. We performed a randomized prospective study, using a validated acute pain rating scale to assess pain during heel-prick combined with five different procedures: (A) control, (B) 10% oral glucose plus sucking, (C) sensorial saturation (SS), (D) oral water, and (E) 10% oral glucose. SS is a multisensorial stimulation consisting of delicate tactile, vestibular, gustative, olfactory, auditory and visual stimuli. Controls did not receive any analgesia. We studied 85 heel-pricks (5 per baby) performed for routine blood samples in 17 preterm infants (28-35 weeks of gestational age). We applied in random order in each patient the five procedures described above and scored pain. SS and sucking plus oral glucose have the greater analgesic effect with respect to no intervention (p < 0.001). The effect of SS is statistically better than that of glucose plus sucking (p < 0.01). SS promotes interaction between nurse and infant and is a simple effective form of analgesia for the NICU. 相似文献

目的了解我国住院极早产儿(very preterm infant,VPI)宫外生长迟缓(extrauterine growth restriction,EUGR)的发生率及影响因素。方法采用多中心前瞻性调查研究方法,纳入2019年9月至2020年12月我国7个地区28家医院新生儿科的2514例VPI临床资料,根据纠正胎龄36周或出院时的体重评估是否发生EUGR,分成EUGR组(n=1189)和非EUGR组(n=1325)。比较两组VPI的临床特征,探讨EUGR的发生情况及相关因素。结果以体重评价,EUGR的发生率为47.30%(1189/2514)。多因素logistic结果显示,恢复出生体重后平均体重增长速率快和住院第1周累计热卡高是EUGR的保护因素(P<0.05),小于胎龄儿、达全肠内营养所需时间长、累计禁食时间长、开始添加母乳强化剂时的母乳量少及达到全强化的所需时间长、中-重度支气管肺发育不良是EUGR发生的危险因素(P<0.05)。结论尽早达全肠内营养,及时强化母乳喂养,增加生后第1周的热卡摄入,提高体重增长速率,以及防治中-重度支气管肺发育不良对降低VPI EUGR的发生率至关重要。 相似文献

The mineral magnesium is a crucial enzymatic cofactor in the cellular bioenergetic process and alternations in magnesium metabolism may be associated with neurological impairment in newborn infants. Therefore, ionized magnesium (IMg) was measured in 14 newborn infants with acidosis [umbilical arterial cord pH 7.00 +/- 0.06, Apgar score 8.3 +/- 1.6 after 5 min, gestational age (GA) 276 +/- 16 d] and 15 premature infants (umbilical arterial cord pH 7.31 +/- 0.07, GA 236 +/- 12 d). Nineteen healthy mature infants served as controls. Arterial umbilical cord samples were taken immediately after delivery and capillary blood samples were taken 2, 6, 12 and 24 h after delivery by heel stick. IMg was measured by NOVA 8. The results showed an increased umbilical cord blood IMg in infants with acidosis compared with both premature and normal infants (0.58 +/- 0.08 mmol l(-1) vs 0.51 +/- 0.03 mmol l(-1) and 0.49 +/- 0.03 mmol l(-1); p < 0.0001). In infants with acidosis IMg declined significantly 2 h after delivery to 0.49 +/- 0.05 mmol l(-1) (p < 0.0001) and did not show any further significant changes during the first day of life. In premature infants and controls IMg levels were constant during the observation period. Conclusion: These findings suggest that elevated IMg is associated with neonatal acidosis. 相似文献

Background
Preterm infants complete their development in Neonatal Intensive Care Unit being exposed to environmental stimuli that lead to the early maturation of the sensory systems. It is known that the fetus perceives sounds and reacts to them with movements since the 26th–28th week of gestational age. Maternal voice represents a source of sensory stimulation for the fetus.Aims
To investigate the effect of the exposure to maternal voice, administered by bone conduction, on preterm infants autonomic and neurobehavioral development.Study design
Longitudinal, explorative, case control study.Subjects
71 preterm infants with birth weight < 1500 g, born adequate for gestational age Outcome measures: vital and neurobehavioral parameters at term, neurofunctional assessment at 3 and 6 months of corrected age.Results
Infants in the treatment group had lower heart rate values and a higher proportion of stable skin color at each study point as compared to the control group. The scores in the visual attention performance and in the quality of the general movements at term were better in the treatment group than in the control one. Neurofunctional assessment score at 3 months of corrected age was higher in the treatment group whereas no difference between the two groups was detected at 6 months of corrected age.Conclusions
Early exposure to maternal voice exerts a beneficial effect on preterm infants autonomic and neurobehavioral development. 相似文献16.
