Catecholamine metabolites in amniotic fluid as indicators of intrauterine stress.
The catecholamine metabolites HMPG and VMA have been determined in samples of amniotic fluid in 38 uncomplicated pregnancies, seven cases of IUGR, and six cases of diabetes. A successive increase of HMPG and VMA was found toward the end of the pregnancy. HMPG and particularly the HMPG/VMA ratio were significantly higher in the amniotic fluid of the growth-retarded fetuses than in the uncomplicated cases. No significant difference was found between the diabetic and uncomplicated cases.
