γγThe items that need to be checked in the hospital in the 2nd month of pregnancy include general examination, ultrasound examination, folic acid bioavailability examination, routine blood examination, blood biochemical examination, routine urine examination and examination of infectious diseases, gynecological examination, etc.γγ1. General examination: it includes weight, blood pressure, heart auscultation, thyroid, breast palpation, etc. 2. Ultrasound examination: it is an important examination item. In the second month of pregnancy, the gestational sac in the uterine cavity can be clearly observed under ultrasound, and at this time, ectopic pregnancy can be excluded through ultrasound examination. In addition, the fetal bud and fetal heartbeat can be seen under the ultrasound to determine whether the fetus is alive or not; 3. Folic acid bioavailability test: folic acid is an important raw material for the synthesis of chromosomes in the fetus, therefore, pregnant women should take folic acid reasonably according to the results of this test; 4. Routine blood test: routine blood test helps doctors understand the physical condition of the mother, and red blood cells mainly determine whether the pregnant woman is anemic. Mild anemia has little effect on pregnant women, but severe anemia can cause premature birth, low birth weight babies and other adverse consequences. A mild increase in total white blood cells during pregnancy is a response of the body and does not indicate infection. Low platelets will affect the coagulation function of pregnant women and need to be investigated. 5. Blood biochemical examination: such as blood glucose, blood lipid, liver and kidney function, etc. Blood glucose includes fasting blood glucose and two-hour postprandial blood glucose, as well as glycosylated hemoglobin and fructosamine, blood lipid examination items include cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, apolipoprotein A, apolipoprotein B, etc. The usual liver function The usual items of liver function include glutathione aminotransferase, glutamic oxalacetic aminotransferase, bilirubin, total protein, albumin, globulin, etc. Kidney function includes creatinine, urea nitrogen, uric acid examination; 6, routine urine examination: mainly check urine white blood cells, urine red blood cells, urine protein, also includes other examination items, can understand the urinary system diseases; 7, infectious disease examination: for example, AIDS, syphilis, hepatitis A, hepatitis B, help timely prevention and control of infectious diseases 8. gynecological examination: to exclude abnormalities of the reproductive tract, to take vaginal secretions for routine examination and chlamydia and gonococcal culture. For pregnant women who are not regularly screened for cervical cancer, TCT tests can be taken. If reproductive tract infection is present, treat for pathogenic bacteria.
