When a woman becomes pregnant, the body will undergo many changes due to the appearance of the fetus to adapt to the presence of the fetus. Therefore, during pregnancy, it is necessary to continuously maintain it, and avoid risks through the doctor's inspection and guidance until the smooth delivery.
For the 280-day pregnancy process, we artificially divide it into early pregnancy, middle pregnancy, and third pregnancy. During this process, we continue to perform health care, which we call perinatal care. During the entire pregnancy, we follow the provisions of the Maternal and Child Health Law. Generally, checkups cannot be less than 13 times. The interval between checkups during early pregnancy is longer, about once a month; checkups are slightly more during the second trimester, about three to two weeks; until pregnancy At the end of the period, check up about once a week until delivery.
How should obstetric examinations be performed during pregnancy?
When menopause occurs, you should go to the hospital as soon as possible to determine whether you are pregnant. In the hospital, you should check HCG (chorionic gonadotropin) and progesterone to understand whether you are pregnant. There is no need to do a B-ultrasound at this time. However, some people will suffer from ectopic pregnancy and the fetus will stop developing, so you should pay attention to whether there is abdominal pain and bleeding. If there is, go to the hospital to see a doctor as soon as possible to avoid accidents. Early pregnancy is a critical period for the development of fetal organs, so if you don't have contraception, you must take it seriously and consider the possibility of pregnancy.
During early pregnancy, under the monitoring of HCG and progesterone, you should go to the hospital to establish a perinatal care relationship and do the first perinatal care check before 12 weeks. During this examination, the doctor will do a whole-body examination, including infectious diseases, blood, eugenics five items, electrocardiogram, etc. The most important thing is to check the B-ultrasound to understand the transparent layer of the fetal neck skin (NT) To determine whether there is a possibility of chromosomal abnormalities, at the same time check the gestational week to determine the correct expected date of delivery. Any value of this inspection is a reference item for the future pregnancy period. It is very important. You must not miss the opportunity of this inspection.
Generally, at 15-20 weeks, the doctor will ask pregnant women for Down’s screening (Down’s, 21-trisomy). If there is a high risk, the doctor will recommend amniocentesis to further check whether the fetus’s chromosomes are abnormal.
After about 20 weeks, do a B-ultrasound of the fetus to screen whether there are abnormalities in the growth of the fetus, such as cleft lip and palate, congenital heart disease, short limbs, anencephaly, hydrocephalus, spina bifida, congenital Absence of kidney, diaphragmatic hernia, etc. If fetal malformations are found, the pregnancy should be terminated decisively.
Pregnant women need to be screened for diabetes between 24-28 weeks of gestation. Generally, blood will be drawn after drinking 50 grams of glucose. If there is any abnormality, the next step will be checked and treated.
In the future, I will come to the hospital to see a doctor about 2-3 weeks, and the doctor will measure the pelvis of the pregnant woman in about 32 weeks to see if she can give birth naturally. In the future, fetal heart rate monitoring during pregnancy will be done to understand the safety of the fetus in the uterus. Check for signs of premature birth, and actively prevent it.
After about 36 weeks, pregnant women should go to the hospital for check-ups once a week, because the fetus will be full-term after 37 weeks, and delivery is possible at any time, so the doctor will do a B-ultrasound to understand the fetus in the uterus, if there is umbilical cord entanglement , The amount of amniotic fluid, placental function, etc., but also to see if the fetus has other problems.
Blood pressure must be measured at each check-up to understand whether the pregnant woman has complications during pregnancy. Because the blood pressure is too high, it indicates that the pregnant woman has chronic hypertension or hypertension during pregnancy. Symptoms, that is, preeclampsia. This is caused by spasm of small arteries of pregnant women, fetal death in the uterus, headache, dizziness and eclampsia of the mother will directly threaten the lives of mothers and children. If the mother's blood pressure is too low, it will lead to insufficient blood supply to the placenta, and the fetus will suffer from intrauterine growth retardation.
Through careful and careful examinations during pregnancy, under the guidance of doctors, you can pass the pregnancy smoothly and give birth to a healthy baby.
Cases of preeclampsia
Ms. Zhang is 31 years old and in good health. After she became pregnant, she thought she was in good health. She had not undergone pregnancy checkups. After 24 weeks, she found dizziness frequently and gradually edema of her lower limbs, so she came to the hospital for checkups.
After examination, it was found to be preeclampsia, blood pressure 170/100mmHg, lower extremity edema, and protein in urine (++). Fetal development is also smaller, which is the result of long-term small vasospasm.The doctor immediately admitted her to the hospital for treatment. After treatment, her blood pressure gradually dropped and stabilized, and urine protein and edema gradually reduced.
Be hospitalized she was discharged after 2 weeks, and when she was discharged from the hospital, the doctor repeatedly reminded her to do the obstetric check-ups on time. But after she was discharged from the hospital, Miss Zhang did not come for a checkup for more than a month.Ms. Zhang showed up at 32 weeks plus one day, because I came personally, and she started to have abdominal pain.
After being admitted to the emergency department and hospitalized, he was diagnosed with preeclampsia and placental abruption, and cesarean section was performed immediately. There was a lot of bleeding during the operation, and because the fetus was too small, neonatal death occurred within one week of treatment in the high-risk neonatal care unit.
Preeclampsia is a comprehensive disease with high incidence during pregnancy. It progresses quickly after the onset and causes great harm. It requires early diagnosis and early attention.
Aucheer PlGF detection kit
Placental growth factor (PlGF) is an important reference indicator for assessing the developmental status of the placenta and is closely related to preeclampsia. When the PlGF content is low, it indicates abnormal placental function, and it is more likely to develop into preeclampsia. The detection of PlGF can be used to identify whether these symptoms of pregnant women are related to preeclampsia, so that appropriate interventions can be made to ensure safe delivery of pregnant women.
