People have lost their hands and their hoofs, and contraceptive measures are obviously done. As a result, "unexpectedly" occurred … So in this case, should the child in the pregnant child stay or not?Come to listen to what the experts who said the prenatal diagnosis center in Guangdong Province.
Emergency contraceptives refer to a class of drugs that prevent or delay ovulation to prevent protective sexual intercourse or contraceptives 72 hours after errors.
The emergency contraceptive plan recommended by the World Health Organization (WHO) is eully, aceticone, or compound oral contraceptives composed of acetyl estradiolin plus acetosol.Single doses of ecosate (30 mg) and Zuo Nonoin (0.75 mg or 1.5 mg) are also common emergency contraceptives.Zuojino progesterone is a progesterone analog, which inhibits ovulation and prevent the bed from bed, and improves the consistency of cervical mucus to prevent sperm from penetrating, thereby achieving contraceptive effects.High -doses of Zuo Nuo Peridone preparations are over -the -counter medicine, which is convenient and easy to obtain. It is currently the most commonly used emergency contraceptive pill.Elishe and macyehyl (10-25 mg) have relatively few applications.
Many people think that after taking emergency contraceptives, there is no worry, but the case of contraceptive failure still happens from time to time. Why is this?
First of all, the effective rate of emergency contraceptives cannot reach 100%.Studies have shown that the contraceptive effect of emergency contraceptives can reach 80-90%, which means that the medicine is used, and 10-20% is still inefficient because it is affected by many factors.Once invalidation occurs, pregnancy is likely to occur as a small probability event.
Second, the method of medication is wrong.The correct usage requires that there is no protective sexual intercourse or contraceptive method to take the first (0.75 mg) as soon as possible within 72 hours after mistakes, 12 to 16 hours after the first table, and then take the second piece.If it is 1.5 mg/ piece, take 1 piece in a single.It should be noted here that if vomiting occurs within 2 hours after taking the medicine, take 1 tablet immediately.
Third, drug interaction.Some drugs can reduce the blood concentration of left germination ketone, which will affect the curative effect.The most common drugs that induce liver enzymes such as Liping, Hypnosis and Anti -Calibal drugs (sodium phenyto, Kamasi equal), and small forsythlery botanical drugs.
In the past, Zuo Nuo Nuo progesterone itself was a progesterone analog. In addition to giving play to progesterone activity, it still has a certain degree ofrogen.Excessive use during pregnancy will affect embryo -organs, leading to male goblin.
In 2012, CFDA revised the pharmaceutical manual about Zuo Nuo progesterone, and added the "known or suspicious pregnancy for those who are known or suspicious" in the 2010 version of the instructions;Grade drugs show that the fetal harmfulness is high and exceeds the scope of treatment benefits.
However, in the stage where sperm and eggs have not been combined or just combined, the embryo has not reached the stage of organ development, following the "fullness and no" influence model.The safety reminder pointed out in the pharmaceutical instructions is for the "known or suspicious pregnancy for those who are known or suspicious." If you are pregnant before emergency contraceptives, the drug will indeed have a serious impact on the growing fetus.
However, the impact of taking emergency contraceptives on the fetus is not applicable. Under the circumstances of being pregnant, women with menstruation have been followed by the "all -and -no" influence model within 28 days from the first day of menstruation, that is, either embryo either embryoIf it is not in shape, either the growth of embryos healthy will have no impact on future fetal health.
Some foreign scholars’ studies of 36 pregnant women who failed to use Zuo Nuojinone emergency contraception found that the fetal congenital malformations, premature birth, and perinatal complications have no significant differences than pregnant women who have not touched Zuo Nuo progesterone, followed by subsequent follow -up.Research also concludes similar conclusions.
In addition, Chinese scholars’ studies have also found that the failure of Zuo Nonourone emergency contraception does not increase the risk of fetal congenital malformations, complications during pregnancy, and adverse pregnancy ending, nor does it affect the physical and intellectual development of future generations.
Based on the global consistent research conclusions, it is believed that after the use of left germone emergency contraception, the fetus can grow and develop normally, and will not have a significant adverse effect.This view has also been supported and recommended by the emergency contraceptive international collaboration group, the International Obstetrics and Gynecology Alliance, and the American Obstetrics and Gynecologist Association.
There are relatively few studies between oligate and non -mekone, but the guidelines of the International Cooperation Group of Emergency contraceptives clearly states that the use of emergency contraceptives (including Zuobinourone, acetic acid ulis, and machetoneone) Pregnant women who are pregnant should know that there is no evidence that emergency contraception failure will have adverse effects on the fetus. Whether choosing to continue pregnancy or abortion, there is no need to make any measures on the impact of emergency contraceptives.
Although emergency contraceptives are convenient, not everyone can use it, especially as conventional contraceptive methods.In addition to bringing possible damage to the embryo, high doses of progesterone preparations also affect women’s health itself.Among them, the most important and serious adverse reactions are to increase the risk of venous thrombosis, stroke and myocardial infarction!Therefore, suffering from thrombotic diseases, cardiovascular and cerebrovascular diseases (especially uncontrollable hypertension), severe hyperlipidemia, diabetes, and minor girls under 16 years old and patients over 40 years old are prohibited.
Secondly, reuse during the same month of the same month will disrupt the menstrual cycle and should be avoided as much as possible.In addition, long -term use will increase the risk of breast cancer and genital cancer, and this type of drug should not be used as conventional contraceptives.Zuojino progesterone needs to be metabolized by the liver, so patients with severe liver dysfunction should not be used.
