Hemorrhages during pregnancy are the conditions requiring emergency therapy. The aim of the investigation was to study the efficiency of tranexamic acid (the drug Tranexam) in arresting bleeding and prolonging pregnancies in women with a history of threatened abortion and miscarriage. In the group of women taking tranexamic acid as part of pathogenetic treatment, hemostasis occurred more rapidly than in the control group and hence uterine hematomas resolved on shorter notice. Inclusion of tranexamic acid into the treatment regimen for patients with threatened and incipient abortion is effective in rapidly arresting hemorrhage and prolonging pregnancy.
