Bakri Balloon Plus Tranexamic Acid During Cesarean Delivery for Placenta Previa

Bakri Balloon Tamponade Plus Intravenous Tranexamic Acid During Cesarean Delivery for Placenta Previa: a Randomized Double-blind Controlled Trial

Objective to investigate the effect of adjunctive intravenous tranexamic acid (TA) on blood loss during cesarean section (CS) in patients with placenta previa undergone Bakri balloon tamponade

Placenta previa (PP) is an obstetric condition that is closely linked with massive obstetric hemorrhage with a varied incidence about once in every 200 live births. It is considered one of the causes of the increased need for blood transfusion and cesarean hysterectomy. PPH due to PP typically starts during cesarean section (CS) in the placental bed, at the lower uterine segment mostly after placental separation. Proceeding for cesarean hysterectomy can be the only effective line of management in spite of the associated high morbidity rate.

Tranexamic acid is a lysine analog which acts as an antifibrinolytic via competitive inhibition of the binding of plasmin and plasminogen to fibrin. The rationale for its use in the reduction of blood loss depending on the implication of the coagulation and fibrinolysis processes implicated in the control of PPH. However, concerns about possible thromboembolic events with parenteral administration of TA have stimulated increasing interest in its topical use.

Inclusion Criteria:

• women undergoing elective cesarean delivery for complete placenta previa which not respond uterotonic and simple hemostatic maneuvers like placental bed hemostatic sutures

Exclusion Criteria:

• patients with the high possibility of morbid adherent placenta
• those presented with severe antepartum hemorrhage
• Patients with cardiac, hepatic, renal, or thromboembolic disease;
• hypersensitivity or contraindications of use of tranexamic acid
• patient refuses to consent
