To establish a new diagnostic method of neonatal meconium aspiration syndrome (MAS).
The fluorometry technique was used for examination of urine samples from three groups of neonates. The neonates were divided into 3 groups: Group I, MAS (n = 17); Group II, no MAS, but amniotic fluid with meconium stain (n = 24); Group III, normal control (n = 27). Urine fluorescence meconium index (UFMI) and urine meconium index (UMI) were calculated.
UFMI values of group I were higher than that of group II and III. The sensitivity and specificity of UFMI were 100% and 97% respectivety. However, it were 51% and 48% respectivety in UMI.
UFMI is an index for identification of Zn-coproporphycin, and it is a more sensitive index for diagnosis of MAS.
建立一种新生儿胎粪吸入综合征（MAS）的新诊断方法。
采用荧光测定技术对三组新生儿的尿液样本进行检测。将新生儿分为三组：第一组，MAS（n = 17）；第二组，无MAS但羊水有胎粪污染（n = 24）；第三组，正常对照组（n = 27）。计算尿荧光胎粪指数（UFMI）和尿胎粪指数（UMI）。
第一组的UFMI值高于第二组和第三组。UFMI的敏感性和特异性分别为100%和97%。然而，UMI的敏感性和特异性分别为51%和48%。
UFMI是鉴定锌原卟啉的指标，是诊断MAS更敏感的指标。
