Abstract

Objective: Intrauterine growth restriction is a leading cause of perinatal mortality and morbidity. Using enoxaparin may enhance the placental circulation and improve the intrauterine growth. This study was conducted to assess the efficacy and safety of enoxaparin in treatment of intra-uterine growth restriction. Study design: 125 women with intrauterine growth restriction were randomized to control group and intervention group (receiving routine high risk pregnancy prenatal care plus daily subcutaneous injection of 40 mg enoxaparin). Prolongation of pregnancy, fetal birth weight, fetal outcome and enoxaparin side effects were compared in 2 groups. Results: Baseline characteristics were similar in 2 groups. Mean gestational age at delivery was 36.73(±2.71) in enoxaparin group and 36.85(±2.17) in control group which showed no statistically significant difference. Mean fetal birth weight had also no statistically significant difference in enoxaparin and control group (2370.16 ± 580.72 g versus 2456.07 ± 543.06 g). Rate of betamethasone administration, intubation, NICU admission, sepsis, necrotizing enterocolitis, intra-ventricular hemorrhage, hypoglycemia and low apgar score were similar in two groups. No major adverse effect was seen. Conclusion: Enoxaparin did not prolong the pregnancy and fetal birth weight and did not improve the fetal outcome even in patients with impaired baseline Doppler findings. © 2021 Elsevier Masson SAS
