Abstract
Subject: The aim of this research is to study the effects of low dose aspirin on preventing any adverse pregnancy outcome in women with aneuploidy abnormal screening tests in second quarter and to compare the effects of aspirin on normal and abnormal Doppler.
Method: This clinical trial study was performed on pregnant women with abnormal aneuploidy screening tests and normal Karyotype at the gestational age 15-18 week. It consists of 83 persons in aspirin receiving group and 84 persons in control group. Doppler ultrasound was simultaneously done on them to survey the Doppler results. Any adverse pregnancy outcome (APO) was compared between two groups.
Results: The frequency of APO was 32.8% in aspirin receiving group and 41.7% in control group (p=o.o14, RR=0.438). The frequency of preterm delivery before 37th week in the group receiving aspirin with normal Doppler was 8.07% and in the control group was 32.7% (P=0.025). The frequency of NICU reception with normal Doppler was 5.8% in aspirin group and 19.7% in control group (p=0.015). APO frequency in the group with many abnormal factors was 11.5% in the group receiving aspirin and 53.8% in control group (p=0.015). APO frequency in abnormal Doppler group was 46.7% in the group receiving aspirin and 50% in control group (p=0.849, RR=0.112).
Conclusion: Low dose of aspirin reduces APO. It reduces preterm delivery and reference of pregnant women to NICU with abnormal aneuploidy screening tests.
