Can I check for pregnancy at the emergency room at night?

If you suspect you are pregnant, you can use a pregnancy test stick at home. Pregnancy is not an emergency and you usually do not need to go to the emergency department for examination at night. In the hospital, pregnancy is confirmed by blood tests and B-ultrasound. B-ultrasound can be done in the emergency room at night, but blood tests cannot be performed. It is best to go to the hospital to register for a blood test in the morning so that the test results can be obtained on the same day.

Can I check for pregnancy at the emergency room at night?

There are two ways to check whether you are pregnant. One is the hcg blood test; the other is an ultrasound examination. The hcg blood test is currently the fastest and most accurate method to check whether a woman is pregnant. The hcg concentration can be detected in the blood as long as the fertilized egg successfully implants for more than 7 days. Through the hcg concentration value, as long as hcg is greater than or equal to 10, it can be confirmed that the woman is pregnant.

However, the hcg blood test is usually conducted in the morning and the results are available in the afternoon. Moreover, in order to make the test results more accurate, blood needs to be drawn on an empty stomach. To take a step back, even if fasting is not required for blood drawing, the medical blood drawing department will go off work on time at night, and only the emergency department will be on duty by doctors. In other words, you cannot do a blood test for pregnancy at night. However, ultrasound examinations can be done at night. There is no distinction between day and night for ultrasound examinations, and even emergency doctors can do ultrasound examinations.

Diagnosis of early pregnancy

symptom

1. For amenorrhea women of childbearing age with a history of sexual life, if their menstruation is delayed by 10 days or more, pregnancy should be suspected. Amenorrhea may be the earliest and most important symptom of pregnancy. But it should be noted that amenorrhea does not necessarily mean pregnancy.

2. Early pregnancy reaction: About half of women experience chills, dizziness, fatigue, drowsiness, drooling, loss of appetite, preference for sour food or aversion to greasy food, nausea, and vomiting in the morning about 6 weeks after menstruation. These symptoms are called early pregnancy reaction. Early pregnancy reactions usually disappear on their own around 12 weeks of pregnancy.

3. Frequent urination Frequent urination occurs in early pregnancy and is caused by the enlarged anteverted uterus compressing the bladder in the pelvic cavity. About 12 weeks after pregnancy, when the uterus enters the abdominal cavity and no longer compresses the bladder, the symptoms of frequent urination disappear naturally.

Signs

1. Changes in the breasts: Starting from the 8th week of pregnancy, the breasts gradually increase in size. Pregnant women feel mild breast tenderness and nipple pain. Examination shows that the nipple and the surrounding skin (areola) are darker in color, and Montessori nodes are visible around the areola.

2. Changes in reproductive organs: A vaginal speculum examination is performed at 6-8 weeks of pregnancy. The vaginal wall and cervix can be seen to be congested and purple-blue in color. As pregnancy progresses, the uterus enlarges and softens. When the uterine fundus extends beyond the pelvic cavity, it can be touched above the pubic symphysis.

Testing

1. Ultrasonic examination B-type ultrasound imaging can not only show the number of fetuses, delivery method, fetal presenting part, fetal position, presence of fetal heart beat and placental position, but also measure multiple diameters such as the biparietal diameter of the fetal head. It can also observe whether there are any fetal surface deformities. Ultrasonic Doppler can detect fetal heart sounds, fetal movement sounds, umbilical cord blood flow sounds and placental blood flow sounds.

2. Fetal electrocardiogram: Currently, the indirect method is commonly used in China to detect fetal electrocardiogram, and the success rate is higher after 20 weeks of pregnancy. The advantage of this method is that it is non-invasive and can be used repeatedly.
