The effect of ritodrine to the mother on plasma renin activity (PRA) in the mother and fetus was examined in 10 mothers coming to elective cesarean section. 10 comparable mothers without ritodrine infusion served as controls. At the end of 2 h infusion of ritodrine, the mean maternal PRA was significantly (p less than 0.001) higher than in the control group. Also the mean PRA levels in the umbilical vein (p less than 0.001) and umbilical artery (p less than 0.01) were significantly higher after ridodrine infusion to the mother than the respective levels in the control group.
在10例行择期剖宫产的母亲中，研究了利托君对母亲及胎儿血浆肾素活性（PRA）的影响。10例未输注利托君的可比母亲作为对照。在输注利托君2小时结束时，母亲的平均PRA显著高于对照组（p<0.001）。母亲输注利托君后，脐静脉（p<0.001）和脐动脉（p<0.01）的平均PRA水平也显著高于对照组的相应水平。
