The aim of this study was to compare the analgesic effect of 2 ml 25% sucrose and human milk in a group of healthy term newborns.
Healthy infants (n = 102) were randomly allocated to receive one of three solutions (sucrose, human milk, sterile water) 2 min prior to taking
a heel prick blood sample. The median values of crying time, recovery time and percentage change in heart rate at 1, 2 and
3 min were recorded in response to the heel prick. Median crying times were 36, 52, and 62 s in the sucrose, placebo and human
milk groups, respectively (P = 0.0009). In the sucrose group, there was a significant reduction in crying time compared to human milk and placebo groups.
Similarly, the median recovery time in the sucrose group (72 s) was shorter than that in the human milk (112 s) and placebo
groups (124 s) (P = 0.004). The percentage change in heart rate at 1, 2 and 3 min was also significantly lower in the sucrose group (P = 0.008, P = 0.01, P = 0.002 at 1, 2, and 3 min respectively).
Conclusion The orosensorial antinociceptive effect of human milk is not as effective as an analgesic as a 25% sucrose solution.

Background: The aim of the present study was to test analgesic effects of double‐ versus single‐dose breast milk and compare this effect with efficacy of double‐ versus single‐dose sucrose in a group of healthy term newborns during heel prick blood sampling. Methods: Healthy newborns (n= 142) were consecutively allocated to one of the six groups: group 1, single‐dose breast milk; group 2, single‐dose sterile water; group 3, single‐dose 12.5% sucrose; group 4, two doses breast milk; group 5, two doses sterile water; and group 6, two doses 12.5% sucrose before the heel prick. The medians for crying time and the pain scores according to the neonatal facial coding system were recorded. Results: Crying times were 117 s, 126 s, 82 s, 128 s, 117 s, and 95 s in groups 1–6, respectively (P= 0.053). The mean pain scores were 4.60, 5.82, 3.91, 4.94, 5, and 4.05 in groups 1–6, respectively (P= 0.068). There was a significant difference between the groups for mean pain scores at 1 min and 3 min. There was a significant difference between the single‐dose sucrose group and single‐dose sterile water group at 1 min (P= 0.002). The babies in the sucrose group were active awake, whereas the ones in the breast milk group were asleep before heel prick. Conclusion: Two doses of sucrose solution were not superior to single‐dose sucrose. Neither single nor double doses of breast milk were effective in relieving pain in neonates. Two milliliters breast milk does not reduce response to pain during minor painful procedures in term neonates even when two doses have been given. Further studies are needed. 相似文献

We used an in vitro assay to study and compare the growth-promotional activity of protein and nonprotein components in human milk (HM) and cow milk (CM) samples for infant strains of Bifidobacterium species. HM samples varied considerably in growth-promotion activity for Bifidobacterium bifidum var pennsylvanicus, Bifidobacterium infantis, and Bifidobacterium breve. Pooled CM samples showed similar but less variable levels of activity when compared with HM samples. Separation of milk samples by ultrafiltration into protein nitrogen and nonprotein nitrogen (NPN) fractions revealed that the bifidobacteria growth-promotion activity of HM was associated primarily with the NPN fraction, whereas activity in CM whey was found in both protein nitrogen and NPN fractions. Testing of purified CM whey proteins showed that alpha-lactalbumin and lactoferrin were potent growth promoters, showing greater activity for B. infantis and B. breve than for two strains of B. bifidum. Conversely, N-acetylglucosamine and purified gastric mucin were highly active for B. bifidum strains but inactive for other Bifidobacterium species. Collectively, the data indicate that both protein nitrogen and NPN factors in HM and CM promote the growth of bifidobacteria and suggest that Bifidobacterium species differ in responsiveness to protein and oligosaccharide growth promoters. 相似文献

OBJECTIVE--To study the hypothesis that ingestion of a modified soy-based formula with an improved mineral suspension system may result in bone mineral content similar to that observed in infants fed human milk or cow milk-based formulas. DESIGN--Prospective, self-selected group of infants fed human milk randomized between the two formula-fed groups. SETTING--University-based hospital nursery and follow-up. PARTICIPANTS--Fifty-six normal, healthy, full-term infants, free of major malformations or disorders, including 17 infants fed human milk, 19 infants fed a cow milk-based formula, and 20 infants fed a soy protein formula were followed up to 6 months' postnatal age. The soy-based formula studied was modified to improve the suspendability of the minerals. INTERVENTIONS--Infants were fed human milk or the study formula for the first 4 months, at which time beikost was permitted. Infants fed human milk received vitamin supplementation to provide 400 IU of vitamin D per day. MEASUREMENTS--Anthropometric variables, serum calcium, magnesium, phosphorus, alkaline phosphatase, and parathyroid hormone levels were measured at enrollment, and at 8, 16, and 24 to 26 weeks' postnatal age. Bone mineral content at the distal third radius site was measured with single photon absorptiometry at these times. Growth in the infants did not differ significantly among the groups. There was no significant difference in serum calcium, magnesium, alkaline phosphatase, or parathyroid hormone concentrations among the infants during the study. Serum phosphorus was significantly lower at 8 weeks in the group fed human milk than in that fed the cow milk-based formula. Bone mineral content at 16 and 24 to 26 weeks was higher in the group fed the soy-based formula than in that fed human milk, and bone width was also higher at 16 weeks in the infants fed the soy-based formula. CONCLUSIONS--Improving the suspendability of the mineral system in the soy formula results in bone mineralization in infants fed the soy-based formula similar to that measured in infants fed human milk and cow milk-based formula. We suggest that the suspendability of the minerals used is an important variable in the interpretation of the effect of feedings on the bone mineral status of infants. 相似文献

Studies from our laboratory have shown that iron is better absorbed from human milk than from cow milk and that human milk can provide insufficient iron for infants during their first year. We compared iron availability from human milk with that from other formulas and determined the factors responsible for its superiority. Adults were fed 100 ml of human milk, simulated human milk, simulated human milk containing added lactoferrin, two commercial formulas containing iron, 12 mg/qt, and human milk that had been boiled. The simulated human milk resembled human milk in concentration of protein, fat, carbohydrate, iron, total minerals, calcium, and phosphorus. Iron 59 was added to each feeding and iron incorporation into RBCs was determined 14 days after each feeding. Percent iron absorption was highest from human milk and lowest from the commercial formulas. The simulated human milk supported a 9.0% absorption; addition of lactoferrin reduced this to 4.7%. Net iron absorption was 0.12 mg/liter from human milk and 0.40 and 0.37 mg/liter from the iron-enriched commercial formulas. Absorption of iron from boiled human milk was the same as from the unboiled milk. This study confirms the unique ability of human milk to promote iron absorption. Simple manipulation of the protein, fat, lactose, calcium, phosphorus, or lactoferrin content of proprietary milk did not reproduce the iron absorption demonstrated with human milk. 相似文献

Midmorning plasma amino acid levels were measured in 31 healthy, very low birth weight infants (mean age 16 days, mean birth weight 1180 g, gestation 29 wk) during 96-h balance studies. All infants received continuous enteral infusion of isonitrogenous, isocaloric preparations of either human milk fortified with pasteurized, lyophilized fractions of mature human milk (n = 18) or whey-dominant cow milk-based formula (n = 13). Weight gain (15 g/kg/day), nitrogen retention (303 mg/kg/day), and metabolizable energy (104 kcal/kg/day) were similar between groups. Plasma levels of threonine, valine, and the sum of essential amino acids were significantly greater in the whey-dominant formula-fed infants (p less than 0.01). Taurine and cystine were measured in significantly greater concentrations in the fortified human milk and threonine, valine, methionine, and lysine in the whey-dominant cow milk formula (p less than 0.01). Relationships between plasma amino acid levels and indices of nitrogen utilization differed between groups. These differences suggest that further modifications of whey-dominant formulas may be indicated. 相似文献

OBJECTIVE: To compare growth of infants fed goat milk infant formula (GMF) or cow milk infant formula (CMF) and to compare tolerability and safety of the two formulas. METHODS: The study was conducted in Auckland, New Zealand. This was a double-blind randomized controlled trial. Newborn term infants were randomized within 72 h of birth to GMF or CMF. Milk formula powder in single serve sachets were reconstituted and fed to infants from trial commencement until age 168 days. No other formula given from randomization until age 168 days. Infant weight, length and head circumference were measured at birth and age 14, 28, 56, 84, 112, 140 and 168 days. Bowel motion frequency and consistency, sleeping and crying patterns and adverse events were also measured. RESULTS: Seventy-two infants were randomized, 36 each to GMF or CMF, with 62 infants completing the intervention. At enrollment the average weight of infants in the GMF group (mean +/- SD) was 3.33 +/- 0.43 kg and in the CMF group 3.43 +/- 0.47 kg; and at study completion 8.07 +/- 0.90 kg (GMF) and 7.87 +/- 0.99 kg (CMF). The difference in average weight gain over the study period for the GMF group versus the CMF group was not significant (+309 g; 95% CI = -49 to +668, P = 0.09). Median daily bowel motion frequency was greater in the GMF group than the CMF group (2.4 vs 1.7, P = 0.01). There were no group differences in bowel motion consistency, duration of crying, ease of settling, or frequency of adverse events. CONCLUSION: Growth of infants fed GMF is not different to that of infants-fed CMF. 相似文献

The purpose of this study was to evaluate mechanisms of mineral homeostasis and mineralization in term infants with recommended vitamin D intakes. Infants fed human milk (nine), cow milk-based formula (11), or soy-based formula (11) were studied at 2 weeks and at 2, 4, 6, 9, and 12 months of age. While receiving 400 IU of vitamin D, all infants maintained serum vitamin D concentrations higher or equal to normal adult concentrations, and serum 25-hydroxyvitamin D levels were maintained at or above normal adult levels. Serum 1,25-dihydroxyvitamin D concentrations were higher than those of adults in the formula-fed but not in the human milk-fed infants. Serum calcium and phosphorus values were similar in all groups; however, urine phosphorus excretion and urine calcium excretion were adjusted to intakes. Serum parathyroid hormone values were normal in all groups. Bone mineral content significantly increased with age similarly in all groups; however, an apparent plateau occurred at 6 months of age in all groups. Bone width steadily increased with age. Taken as a whole, these data suggest that the vitamin D-sufficient term infant fed human milk, cow milk-based formula, or the soy-based formula studied can regulate mineral metabolism within acceptable physiologic limits to attain similar levels of serum minerals and bone mineral content. 相似文献

BACKGROUND: Aluminum toxicity is well documented and contamination of milk formulas has been implicated as the source of accumulation in bone and brain tissues. The purpose of the current study was to evaluate the aluminum contents of human milk, cow's milk, and infant formulas. METHODS: Aluminum contents were determined by atomic absorption spectrometry in samples of human milk in the colostrum, intermediate, and mature stages; infant formulas from eight manufacturers; and various types and brands of commercially available cow's milk. RESULTS: Mean aluminum concentration was lowest in human milk (23.4 +/- 9.6 microg/l), and did not differ significantly between colostrum, intermediate-stage and mature-stage milk. Mean aluminum concentration was 70 microg/l in cow's milk, and 226 microg/l in reconstituted infant formulas. Aluminum concentrations in infant formulas differed markedly among manufacturers; concentration in milk from one of the manufacturers was particularly high (mean, 551 microg/l; range, 302-1149 microg/l). These values are for milk reconstituted with aluminum-free water under laboratory conditions; formulas prepared with tap water in the University Hospital's infant-feeding unit had even higher aluminum content. Experiments showed that aluminum concentration in the high-aluminum milk could be reduced by more than 70% at the manufacturing stage, by using low aluminum components. CONCLUSIONS: The results of the present study support the recommendations for infant formula manufacturers to strive to reduce aluminum concentration in their products. 相似文献

The selenium content of human milk, cow's milk and cow's milk infant formula were estimated by instrumental neutron activation analysis. The highest values were found in 3 samples of human colostrum (524–865×10-9 g/g dry weight). There was a significant decrease with increasing time post partum. Mature human milk exhibited a selenium content of 230±79×10-9 g/g dry weight.The selenium content of 45 samples of cow's milk from the north-western area of Germany was 200±39×10-9 g/g dry weight. While there was no significant difference between the values of mature human milk and of cow's milk, cow's milk infant formula exhibited significantly (P<0.01) lower values than human milk. The average selenium content of 107 samples of 10 different commercially available fluid and powdered cow's milk infant formulas (range: 18–171×10-9 g/g dry weight) amounted to about only one third of that in mature human milk.With support of the Deutsche Forschungsgemeinschaft 相似文献

The ganglioside compositions of human milk, cow's milk and infant formulas were compared. The results showed that there was a drastic change in the ganglioside composition from the colostrum to later human milk, and that both the patterns and contents of gangliosides in human milk, cow's milk and infant formulas differed markedly. In human milk, the total lipid-bound sialic acid level was two times higher than those in cow's milk and infant formulas. The major ganglioside in the later human milk, GM3 (27.7%), was only a minor component in the colostrum, cow's milk and infant formulas (3.3, 2.8 and 0.4-2.6%, respectively). GD3 represented 49.0, 61.0 and 72.4-86.6%, respectively, of the colostrum, cow's milk and infant formulas, compared to 31.8% of the later human milk gangliosides. Another four gangliosides, which were assumed to be c-series gangliosides, were detected in the colostrum and the later human milk. They represented 33-38% of total lipid-bound sialic acid, and were tentatively designated as GX1, GX2, GX3 and GX4, respectively. However, only GX1 and GX2 were observed in cow's milk and infant formulas. The variation of the gangliosides in human and cow's milk, and infant formulas might have some biological significance regarding neonatal brain development, allergies, infant growth and non-immunoglobulin prophylactic activities against some bacterial toxins. 相似文献
