Abstract
Objectives
To compare the effect of sildenafil citrate (SC) and low molecular weight heparin (LMWH) on neonatal birth weight (BW) and the fetoplacental blood flow in pregnancies with FGR.
Study design
A parallel groups, randomized clinical trial was conducted at a university hospital, between June 2017 and September 2018, involving 100 pregnant women with placental mediated FGR between 28 and 35 weeks of gestation who were randomly assigned to receive either SC or LMWH started at FGR diagnosis till delivery.
Results
The neonatal BW in LMWH group was higher than SC group (pā<ā0.000) with a longer time from randomization till delivery, LMWH group had significant improvement in Ut A PI, UA PI, and MCA PI compared with SC treated group with p values 0.005, <0.000001, and 0.014, respectively.
Conclusion
The neonatal BW, time from randomization to delivery, and fetoplacental blood flow indices were significantly better with LMWH use compared with SC.
