I heard that B-ultrasound examination needs to hold urine. Lili, who went to the hospital for filing, drank two bowls of soup early in the morning. She could not only feed herself but also produce a lot of urine, which made the examination more smooth. However, Lili, who was waiting in the hospital for an examination, found that the facts were totally different from what she had heard. The original 12 weeks of pregnancy filing examination needs to be fasting instead of holding urine. After waiting for an hour and a half, Lili, tired and exhausted, can only go home to wait for the next day’s examination. < p > < p > in fact, during the pregnancy examination of tingling Ma, there were many detours because of fasting and holding urine. The first examination was 8 weeks of gestation. I went to the hospital in the afternoon. I drank a lot of water before I went to the hospital. I ran to the toilet several times and finally felt comfortable. However, when I came to my examination, I couldn’t see clearly the images in the uterus. I could only continue to drink water and wait for the urine to hold, and it took me more than an hour to finish the examination. < / P > < p > this is because in the early pregnancy, there is only one small embryo. Although the uterus has increased, it is still located deep inside the pelvic cavity. During the examination, due to the intestinal peristalsis and the interference of internal substances, it is likely to affect the image of the uterus, making the examination unable to proceed smoothly. < / P > < p > however, if the bladder is full, the bladder can move the position of the intestinal tube to the upper part, which can avoid the interference of intestinal peristalsis, and can also see the images in the uterus clearly through the bladder, so that the examination can be carried out more smoothly. < p > < p > after 12 weeks of gestation, the uterus expands and moves upward, and it is farther and farther away from the bladder. Therefore, it is not necessary to hold urine. < / P > < p > as long as the pregnant woman can feel the obvious urine, do not over suppress urine, not only feel sad, but also make the bladder over filled, causing serious compression of pelvic cavity and other organs, and it is easy to make a wrong judgment during the examination. < / P > < p > PS: Although the early pregnancy examination is not necessary, in recent years, the occurrence of embryo abortion, threatened abortion and ectopic pregnancy is increasing. < / P > < p > for the sake of safety, it is recommended to do at least one B-ultrasound examination in the early pregnancy. The examination time is about 8 weeks of pregnancy. If there is any abnormality before, you should also seek medical treatment as soon as possible! < / P > < p > many pregnant women don’t know much about fasting. They don’t feel sick and sad when they don’t need fasting; they just don’t go on an empty stomach when they need to, and they take many detours. < / P > < p > if there is no examination in the first trimester of pregnancy, there will be a lot of examination items in the 12th week of pregnancy. The doctors will make clear the B-ultrasound examination, routine examination and basic information consultation. This examination must be on an empty stomach. < / P > < p > examination instructions: not only should the above contents be checked, but also many information will be asked, such as whether there is a history of abortion, whether there is a genetic history, whether there is drug allergy, and the history of pregnant women. < / P > < p > pregnant women need to draw blood. The main purpose is to test the blood type and hemoglobin of pregnant women, screen for thalassemia, liver function, renal function and syphilis, hepatitis B, AIDS, virus infection, etc., so as to prevent the health in the future. < / P > < p > the specific process is as follows: the pregnant woman fasted at about 10 o’clock the night before, and went to the hospital in the morning for check-up. When drawing blood for the first time, she was on an empty stomach. After drawing blood, she got a bag of glucose water and drank it within 5 minutes. Drink slowly. Don’t choke yourself. Take one hour after drinking, and another two hours later. < / P > < p > generally speaking, the end of blood drawing is almost noon, and pregnant women who fasted all night + all morning are very sad, so it is suggested that they should take some food and drink during the examination, and eat quickly after the blood drawing to relieve discomfort; moreover, it is better to have family members with them, otherwise the pregnant women will be dizzy and dizzy, nauseous and uncomfortable, which will easily lead to problems. < / P > < p > some may be 36 weeks of gestation, and some may be 37 weeks pregnant. Please consult the hospital for details. Check blood, mainly check HIV antibody, hepatitis B surface antibody, syphilis antibody and so on, these items must be carried out on an empty stomach. < / P > < p > if it is 36 weeks of gestation, there is a very important fetal heart rate monitoring; if it is 37 weeks of pregnancy, it is basically routine examination, such as: uterine height, abdominal circumference, fetal heart rate, blood pressure, weight, etc. The test items include blood routine test, liver function test, renal function test, HIV antibody test, hepatitis B surface antibody test, syphilis antibody test, urine routine test, blood coagulation test, secretion test, etc. Auxiliary examinations included pelvic measurements and Doppler echocardiography. PS: although it is said that there are at least three times of urine holding during the 13 times of pregnancy, the specific time varies from hospital to hospital. After all, the health of each pregnant woman is different, the development of the fetus is different, and the establishment of obstetric examination items in different hospitals is different. The specific inspection items and times are also different. The specific requirements should be determined by the hospital, and it is better to carry out under the guidance of doctors. There are many examinations during pregnancy, and there are many problems to be paid attention to, especially the requirements of fasting and holding urine. Pregnant women must be clear and prepared early to avoid suffering from detours. Hello, everyone. I am an experienced child care expert. I am the original author of multi platform.
