What is the purpose of administering Dalteparin Sodium to pregnant women?

The use of dalteparin sodium in pregnant women serves as an anticoagulant, clinically used to treat threatened abortion, hypercoagulable state during pregnancy, and history of thrombosis. Details are as follows:

1. Threatened Abortion: If a pregnant woman experiences threatened abortion, especially with a history of recurrent abortions, it may indicate the presence of risk factors such as antiphospholipid syndrome or systemic lupus erythematosus. In such cases, dalteparin sodium is injected to perform its anticoagulant role, which can increase placental perfusion and prevent fetal growth restriction.

2. Hypercoagulable State During Pregnancy: Some pregnant women may be excessively obese or have risk factors such as gestational hypertension or diabetes. When blood tests indicate a hypercoagulable state, dalteparin sodium is also injected for its anticoagulant effect, which helps improve local blood flow in the uterus and placenta, promoting normal fetal development.

3. History of Thrombosis: Some pregnant women may have a history of thrombosis or spend long periods of time in bed. After pregnancy, dalteparin sodium is also injected to prevent the formation of thrombosis.

The administration of dalteparin sodium in pregnant women has specific indications and should only be used under the guidance of a physician. Close monitoring of coagulation function is also required, with dose adjustments made based on test results.
