In addition to low-molecular-weight heparin, what other methods of fetal protection are there?
Ms. Huang used low molecular weight heparin (LMWH) for pregnancy protection. The indications of low molecular weight heparin in the field of obstetrics and gynecology and reproduction are mainly abortion caused by antiphospholipid syndrome (APS), thrombus proneness (PTS), autoimmune disease (AID) and other reasons. Currently commonly used LMWH preparations include dalteparin, enoxaparin, and nadroparin. The method of use is subcutaneous injection, which can be injected by pregnant women.
However, for patients with unexplained recurrent spontaneous abortion (URSA), recurrent biochemical pregnancy (RBP) and repetitive implant failure (RPF), there is still no basis for using LMWH to improve pregnancy outcomes.
In addition to low-molecular-weight heparin, the commonly used early pregnancy protection drugs in clinical practice include progesterone preparations (progesterone, dydrogesterone), chorionic gonadotropin (HCG), etc., while the commonly used early pregnancy protection drugs in the third trimester include:
Calcium channel blocker: nifedipine tablets
Prostaglandin Synthase Inhibitor: Indomethacin
β-adrenergic receptor agonist: ritodrine
Tococeptor antagonist: Atosiban
In addition to medication, if a pregnant woman has a miscarriage due to cervical insufficiency, it can be prevented by cervical cerclage surgery.
Clinically, you should choose an appropriate treatment plan according to the specific conditions of pregnant women. During the period, you should follow the doctor's advice to strengthen the examination of the fetus and yourself. Never take drugs at will to protect yourself.
