among obstetricians ambiguous attitude to aspirin.Many doctors recognize the positive properties of aspirin, which could be useful during pregnancy.But often outweigh its negative features, chief of which is the negative impact on the fetus.
aspirin in the first trimester of pregnancy
In the appointment of aspirin in the first trimester (first 12 weeks), there is no disagreement: take this medication during Bookmarks organs and tissues of the fetus is dangerous, it can lead to abnormalities infetus.Particularly negative impact on the development of aspirin genitals.For example, it is believed that this drug can cause cryptorchidism - undescended testicle into the scrotum.
The same negative effects on the fetus and have all the other non-steroidal anti-inflammatory drugs.Therefore, they are not recommended to use as antipyretics for colds and viral diseases in pregnant women.The safest in this case is paracetamol.
aspirin in the second trimeste
In the second trimester (12-24 weeks) aspirin is not contraindicated, but it may appoint a doctor.During this period of pregnancy aspirin are sometimes prescribed to improve blood circulation in the placenta and prevent thrombosis in pregnant women.
When poor circulation in the placenta occurs fetoplacental insufficiency (FPI) - a condition in which due to insufficient blood vessel patency to the fetusgoes low in nutrients and oxygen.This leads to a lag in the development of the child.But the main danger FPN is sharply negative impact on the brain of the fetus to lack of the required amount of oxygen in the blood.This can lead to serious disorders of the central nervous system of the newborn child.
Therefore FPN time trying to identify and eliminate.Including sometimes to improve blood circulation and the suppression of the formation of blood clots that disrupt blood circulation, prescribed low-dose aspirin in the form of long-term courses.However, these doses are much lower than the doses used for the purpose of analgesia or decrease in temperature, so they usually do not give side effects.
Sometimes small doses of aspirin are appointed in severe varicose veins varicose veins - the operation is inevitable? women in the second trimester of pregnancy.
aspirin in the third trimester of pregnancy
In the third trimester of pregnancy (24 to 40 weeks) officially aspirin is contraindicated due to the possible threat of bleeding during childbirth.Such a threat may be real with placenta previa (when the placenta partially or completely covers the way out of the uterus), premature detachment of the placenta and in some other states.
However, aspirin in low doses are sometimes prescribed in this period if, for example, remains a threat to the development of FPN.In the third trimester of pregnancy and sometimes develops toxicosis second half of pregnancy - preeclampsia.At the heart of preeclampsia is a violation of the circulation of blood in the smallest blood vessels - capillaries.As a result, women appear at first hidden and then clear edema, increased blood pressure Blood pressure - dangerous if his swing? , a protein found in the urine (a consequence of the defeat of the blood vessels of the kidneys).If this condition is not the time to identify and treat, it will lead to serious complications of the central nervous system.
Aspirin in this case thins the blood by preventing platelet adhesion and aggregation of platelets - what they are for the body? (their ability to adhere to the walls of blood vessels and grouped with the subsequent formation of a blood clot).This leads to the fact that the movement of blood through the capillaries (microcirculation) improves.Of course, the aspirin in this case, is not a panacea and it is not assigned its own, but as part of comprehensive treatment.
Another indication for aspirin is premature aging of the placenta.Normally, the placenta begins to age until the end of pregnancy: zapustevayut some blood vessels, which reduces the risk of bleeding during childbirth.But sometimes the process of aging of the placenta begins much earlier norms and leads to impaired fetal development Fetal development - week after week and complications of the central nervous system.
Aspirin in this case appointed with great care, since it is always necessary to remember that the risk of bleeding during childbirth is real.However, small doses of aspirin can halt premature aging of placenta and improve blood flow to the fetus.
Aspirin belongs to the drugs, which in any case can not be taken alone during pregnancy.
