Intravenous Tranexamic acid versus placebo during Caesarian section: A comparative study.

Area of Science:

• Obstetrics and Gynecology
• Pharmacology

Background:

• Postpartum hemorrhage (PPH) remains a leading cause of maternal morbidity and mortality worldwide.
• Cesarean sections, particularly in high-risk pregnancies, are associated with an increased risk of PPH.

Purpose of the Study:

• To evaluate the efficacy of Tranexamic Acid in preventing PPH in high-risk women undergoing cesarean section.
• To compare Tranexamic Acid with a placebo in this specific patient population.

Main Methods:

• A double-blinded, placebo-controlled trial involving 60 high-risk women scheduled for elective cesarean section.
• Participants received either Tranexamic Acid or a placebo prior to skin incision.
• Blood loss and postoperative complications were monitored within 24 hours.

Main Results:

• The incidence of PPH (blood loss >1000 ml) was significantly lower in the Tranexamic Acid group (16.6%) versus the placebo group (60%) (p<0.01).
• The requirement for additional uterotonic agents was reduced in the Tranexamic Acid group (13.3% vs 43.3%).
• Fewer patients in the Tranexamic Acid group needed blood transfusions (6.0% vs 23.3%).

Conclusions:

• Tranexamic Acid is effective in controlling PPH during and after cesarean sections in high-risk women.
• The use of Tranexamic Acid can decrease the need for secondary interventions like uterotonics and blood transfusions.
• This study supports the routine use of Tranexamic Acid for PPH prevention in this demographic.
