aminocaproic acid and Postpartum Hemorrhage

aminocaproic acid has been researched along with Postpartum Hemorrhage in 7 studies

Aminocaproic Acid: An antifibrinolytic agent that acts by inhibiting plasminogen activators which have fibrinolytic properties.
6-aminohexanoic acid : An epsilon-amino acid comprising hexanoic acid carrying an amino substituent at position C-6. Used to control postoperative bleeding, and to treat overdose effects of the thrombolytic agents streptokinase and tissue plasminogen activator.

Postpartum Hemorrhage: Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
