[Importance of measuring blood flow in monitoring pregnancy-induced hypertension and IUGR].
Doppler flow velocimetry of uterine and fetal vessels is carried out in high risk pregnancies. However, there is controversy about the predictive value of elevated resistance indices (RI) with respect of adverse fetal outcome. Therefore we estimated the frequency of elevated RI in uterine and fetal vessels in pregnant women with documented pregnancy induced hypertension (SIH, n = 9), intrauterine growth retardation (IUGR, n = 16) and uncomplicated pregnancies (n = 8). The results of the doppler flow velocimetry were compared to the fetal outcome. Elevated RI were observed in all vessels in the two groups with SIH and IUGR. In contrast, all RI in the control group were found to be in the normal range. The frequency of elevated RI in the a. uterine was slightly but not significantly higher in the SIH group than in the IUGR group. Approximately 50% of the infants of the groups with SIH and IUGR were born prematurely. However, in all but 4 infants apgar score and pH of cord blood were in the normal range. Decision for premature delivery in the IUGR group were mostly based on elevated RI. It is concluded that this may have led to delivery before fetal decompensation occurred and thus may have had a positive effect on fetal outcome.
