A simplified scoring system for clinically determining fetal maturation of newly born infants has been developed and provides accurate assessment of gestational age in either well or sick babies. Certain conditions render individual criteria within the score less reliable but do not significantly lessen the reliability of the total assessment. The optimal age for maturational assessment is between 30 and 42 hours of age.
一种用于临床确定新生儿胎儿成熟度的简化评分系统已被开发出来，它能准确评估健康或患病婴儿的孕周。某些情况会使评分中的个别标准不太可靠，但不会显著降低总体评估的可靠性。成熟度评估的最佳年龄在出生后30至42小时之间。
