胎龄小于 ２８周早产儿存活率的提高，为建立体重增长曲线提供了必要性， 同时也提供了可行性。通过对１２３例胎龄小于２８周早产儿生后头１０周体重增长总 结分析，结果发现出生初期有明显的体重下降，平均于生后６天体重最轻，平均体重 丢失约 １１％。平均生后 １７天恢复至出生体重，平均于生后 ６６天２倍于出生体重，胎 龄小于２５周的早产儿生后体重增长速率稍落后于胎龄２５～２７周的早产儿，性别和 种族对体重增长的影响无显著性差异，多胞胎早产儿体重增长速率于生后４周后稍 快于单胞胎早产儿。本文建立的胎龄小于２８周早产儿生长头１０周体重增长曲线及 其体重增长参数，有实际应用价值，可为国内临床提供参考。
The improvement of survival rate of gestational age less than 28 weeks premature babies provides the necessity to establish the weight growth curve, and also provides the feasibility. Through 123 pairs of gestational age less than 28 weeks of premature infants born in the first 10 weeks after birth weight gain summary analysis showed that early birth have significant weight loss, the average 6 days after birth, the lightest weight loss of about 11% of the average body weight. Average 17 days after birth to return to birth weight, an average of 66 days after birth, 2 times the birth weight, gestational age less than 25 weeks of premature infants after birth weight growth rate slightly behind the gestational age of 25 to 27 weeks of preterm children, gender and There was no significant difference in the effects of race on weight gain. The rate of weight gain of multiple premature children was slightly faster than that of singleton premature children 4 weeks after birth. The establishment of the gestational age of less than 28 weeks of growth of premature infants growth head 10 weeks weight gain curve and weight gain parameters, has practical value, can provide a reference for the domestic clinical.
