Low-dose aspirin to improve perinatal outcome

Area of Science:

• Obstetrics and Gynecology
• Pharmacology
• Neonatal Health

Background:

• Aspirin's therapeutic applications are expanding.
• The use of aspirin during pregnancy presents potential risks and benefits, with some findings being contradictory.
• Potential adverse effects on infants and the efficacy of low-dose aspirin remain under investigation.

Purpose of the Study:

• To review the current literature on low-dose aspirin use in pregnancy.
• To assess the safety and efficacy of aspirin for preventing preeclampsia and fetal growth retardation.
• To provide guidance on aspirin administration during pregnancy.

Main Methods:

• Literature review of over 300 pregnancies involving low-dose aspirin.
• Analysis of ongoing large clinical trials in the US and internationally.
• Clinical monitoring protocols for pregnant patients receiving aspirin.

Main Results:

• A review of existing literature shows no major adverse effects in over 300 pregnancies with low-dose aspirin.
• Current data suggests aspirin can be continued until delivery without complication.
• Ongoing trials are evaluating low-dose aspirin for preeclampsia and fetal growth retardation prevention.

Conclusions:

• While promising, the benefits of low-dose aspirin in pregnancy are still experimental.
• Caution against indiscriminate aspirin use in pregnancy is recommended until more conclusive evidence is available.
• Clinicians should carefully monitor mothers, fetuses, and neonates when using aspirin during pregnancy, initiating therapy after the first trimester.
