Hyacinth Science: the placenta is not honest, you need to know! Sohu, pregnancy, and fetal appendages occurred may cause adverse pregnancy outcome of abnormal, endanger mother’s life, the placenta as fetal appendages, if in the process of formation of abnormal position, it will be the formation of placenta previa, influence of mother and child, what is the placenta? Placenta previa is an abnormal lesion of placenta. In normal pregnancy, the placenta is attached to the posterior, anterior or lateral walls of the uterus. After 28 weeks of pregnancy, the placenta was attached to the lower uterine segment, and the lower edge of the placenta even reached or covered the cervix. TIPS type of placenta previa but the inferior edge of the placenta with cervical internal relationship is not immutable and frozen, along with the gradual lower uterine segment, gradually disappear cervix, cervical mouth expansion and change. The classification of placenta previa may change with the development of pregnancy and labor. Therefore, in complete placenta previa before labor but also because of the cervix expansion into partial placenta previa. Therefore, the classification can vary with the time of pregnancy or the progress of labor, and all of them are determined by the last examination before treatment. What are the clinical manifestations of placenta previa? 1 features: vaginal bleeding in late pregnancy painless vaginal bleeding; in late pregnancy, the formation and extension of lower uterine segment, the placenta can follow the corresponding extension, lead to the attachment point of dislocation and debonding, resulting in sinus rupture and bleeding. This bleeding can occur frequently with the gradual lengthening of the lower uterine segment. 2 anemia, shock: repeated bleeding can lead to anemia, the degree of vaginal bleeding. 3 fetal abnormalities: due to abnormal placental location, fetal head is often high floating, about 13 of pregnant mother appeared abnormal fetal position, among which the most common breech. How to diagnose and deal with the diagnosis? Late pregnancy or birth after painless vaginal bleeding requires attention, at the same time combined with imaging examination can confirm the diagnosis of color Doppler ultrasound or magnetic. Among them, the color Doppler ultrasound examination is an effective method of placenta previa, the accuracy rate of 95%, so suspected placenta previa pregnant mother can go to the hospital to do a color Doppler ultrasound to help diagnose. MRI can be used to help diagnose if necessary. How to deal with it? 1, look forward to treatment: for vaginal bleeding or no prenatal bleeding, vital signs stable, fetal survival, gestational age less than 34 weeks, fetal lung immature pregnant women. Can be in the premise of maternal and child safety, as far as possible to extend the gestational age, in order to facilitate the survival of the fetus, there is vaginal bleeding in patients with emphasis on hospitalization in the hope of treatment, and in the mother and child rescue conditions of the hospital. Need absolute bed rest during this period, the left lateral position is preferred, intermittent oxygen, close observation of blood loss, prohibit sexual life less than 34+6 weeks of pregnancy stimulate, promote fetal lung treatment at the same time, relaxed state of mind to avoid anxiety is a must. In addition, the corresponding process can be based on individual circumstances, including inhibition of uterine contraction, anemia (according to the degree of anemia) or prevention of infection. Before the life of the pregnant woman vagina bleeding 2, regardless of gestational age should be an emergency cesarean section!相关的主题文章:
