24 weeks placenta previa to bed?
summary
If we compare the fetus to a sapling, then the placenta is equivalent to the root of the sapling, the uterus is equivalent to the soil, and the implantation is equivalent to that the seeds start to take root and germinate on the soil, and the maternal nutrients are transported to the fetus through the placenta and umbilical cord. Today we are going to talk about is placenta previa can grow up? There is no doubt that the answer is No. Because from the moment of implantation, the position of embryo growth is determined. Let's take a look at placenta previa.
24 weeks placenta previa to bed?
1. Let's first look at placenta previa. It is the placenta attached to the lower uterine segment after 28 weeks of pregnancy, and even the lower edge of the placenta reaches or covers the cervix. Placenta previa is generally divided into three categories, namely complete placenta previa, partial placenta previa and marginal placenta previa. The main symptom of placenta previa is painless recurrent vaginal bleeding in late pregnancy or labor. The degree of anemia is related to the amount of bleeding. The more blood loss, the more severe anemia. Pregnant women with placenta previa generally only do vaginal speculum, no finger diagnosis.
2. In general, ultrasound is the first choice. Because B ultrasound can not only diagnose placenta previa, but also know the type of placenta previa, and the accuracy rate is as high as 95%. The treatment principle of placenta previa is to stop bleeding and prevent infection. According to the patient's condition, we can expect treatment. Expectant therapy is generally applied to less than 37 weeks of pregnancy and fetal weight less than 2300G. If repeated massive hemorrhage leads to shock, pregnancy should be terminated whether the fetus is alive or not (cesarean section is the main means to terminate pregnancy).
3. After understanding the characteristics of placenta previa, we should know that placenta previa should absolutely rest in bed, strengthen nutrition, correct anemia, avoid stimulation, prohibit anal examination, in addition, we should not do vaginal examination and strengthen perineal care to prevent infection. Intermittent oxygen inhalation was given twice a day for 30 minutes each time to increase the blood oxygen supply of the fetus. According to the doctor's advice, blood tonifying drugs, uterine relaxants and fetal lung ripening drugs (dexamethasone can promote fetal lung ripening) were used. In addition, preoperative preparation and neonatal rescue preparation should be made according to the doctor's advice to prevent sudden massive hemorrhage.
matters needing attention
Blood pressure, pulse, temperature and infection were monitored. Vaginal bleeding was observed. It can be weighed by the amount of toilet paper. Especially in massive hemorrhage, the symptoms and signs of shock should be observed. Observe the condition of fetus. Absolute bed rest. Left recumbent position. Follow the doctor's advice. Appropriate use of drugs to promote fetal lung maturation.
