Abstract
We measured the excretion rate of endogenous creatinine in 84 24-hour urine collections obtained from 60 term and preterm newborn infants between the 3rd and the 68th postnatal day, at postconceptional ages 28-42 weeks. The rate was positively correlated with weight, height, and postconceptional age but not with postnatal age; the strongest correlation was that with weight. When the rate was factored by weight it was constant across the range of values studied, with a median and logarithmic mean value of 90 mumol/kg/day (10 mg/kg/day) and a range (2 log SD) of 45-180 mumol/kg/day (5-20 mg/kg/day).
摘要
我们测量了从60名足月和早产新生儿在出生后第3天至第68天收集的84份24小时尿液样本中的内源性肌酐排泄率，这些新生儿的孕龄为28 - 42周。该排泄率与体重、身高和孕龄呈正相关，但与出生后年龄无关；与体重的相关性最强。当排泄率按体重进行校正后，在所研究的数值范围内保持恒定，中位数和对数平均值为90 μmol/kg/天（10 mg/kg/天），范围（2倍标准差）为45 - 180 μmol/kg/天（5 - 20 mg/kg/天）。
