[Significance of detecting meconium-like substance in maternal urine in perinatal monitoring].
Urinary meconium index (UMI) was determined in 538 cases of pregnant women by spectrophotometry (265 cases were in late pregnancies 229 in the first stage of delivery, and 44 in the second stage). The results indicated that most of those having positive UMI were high-risk pregnancies (P less than 0.01). The UMI index of the meconium contaminated amniotic fluid was higher than the non-contaminated amniotic fluid (P less than 0.01), and patients with lower Apgar score had higher rate of positive UMI. In consecutive measuring, , We found that the rate of neonatal asphyxia was highest in those with a UMI of falling type, and then in the rising type. It showed that measurement of maternal UMI is of value in monitoring high-risk pregnancies.
