Low-Dose Aspirin in the Prevention of Hypertensive Disorders of Pregnancy in Relatively Low-Risk Nulliparous Women

Abstract

Objective: To assess the role of low-dose aspirin in the prevention of hypertensive disorders of pregnancy in relatively low-risk, healthy, nulliparous women.Method: Randomized, double-blind, placebo-controlled trial involving 118 healthy, nulliparous women with a high hemoglobin concentration in the second trimester. Participants took either 75 mg aspirin or placebo from 18 weeks until delivery.Main Outcome Measures: Patient characteristics. Pregnancy outcome including incidence of hypertensive disorders of pregnancy.Results: There was no difference in pregnancy outcome between the two groups. Specifically, the odds ratio for the incidence of hypertensive disorders of pregnancy was 1.64 (95% CI 0.59–4.6). The overall incidence of emergency caesarean section in the two groups was similar. The odds ratio for delivery by emergency caesarean section in labor was 1.29 (95% CI 0.5–3.16). There was no difference in neonatal outcome in terms of admission rates to a neonatal intensive care unit and no difference ...
