1. How many weeks are premature birth
Pregnancy reaches 28 weeks, and the delivery occurs within 37 weeks, which is called premature birth.
The newborn that is born during this period is called premature baby .
Due to the improvement of treatment technology for premature infants and the improvement of prognosis of premature infants, some developed countries have appropriately defined the lower limit of premature birth as 24 weeks of pregnancy, or even ahead of the 20 weeks of pregnancy. According to gestational age and prognosis of premature babies, some people further classified premature birth, adding premature birth to 34 weeks of gestation to 36 weeks of gestation, which is called late premature birth.
32 weeks of pregnancy to 33 plus 6 weeks of gestation, premature birth that occurs is called mid-term premature birth, 28 weeks of pregnancy to 31 plus 6 weeks of gestation, premature birth that occurs is called early early, and premature birth that occurs is less than 28 weeks of gestation, is called extremely early premature birth. The development of all organs of premature babies is not perfect enough. The smaller the gestational week, the lighter the weight of birth, and the worse the corresponding prognosis.
Currently, premature birth in China accounts for about 5% to 15% of the total (24:59), and this proportion is still worthy of vigilance. After birth, about two-thirds of babies die within one year of the year are premature babies, so we should recommend strengthening prenatal examinations to prevent the birth of premature babies.
2. What are the signs of premature birth
If any of the following symptoms appear between the 28th week of pregnancy and 37th week of pregnancy, it is considered as a sign of premature birth.
1. The vaginal secretions increase, or the characteristics of the secretions change. The changes in the characteristics refer to the secretions becoming aqueous mucus-like, or bloody.
2. Vaginal bleeding occurs or drip bleeding occurs.
3. Abdomen pain occurs. This pain is similar to the pain of menstruation. Sometimes it will be accompanied by abdominal grooves and persistent soreness. Or it may appear that the uterine contraction is regular, and the uterine contraction is more than 4 times within an hour. Even if there is no pain during the contraction, the lower abdomen will repeatedly become hard and soft, and the muscles will experience a strong swelling.
4. There is a gradually increasing feeling of pressure at the bottom of the pelvic floor.
5. Pain in the waist and back.
6, amniotic fluid flows out. Once you find that there is a liquid like warm water in the lower body, it will flow out slowly like urine. This generally means that the water is broken. At this time, we should raise our buttocks as much as possible, it is best to keep it lying flat and keep the pads clean and hygienic. If the above signs occur, you must go to the hospital immediately and treat fetal care and delivery in a timely manner.
3. What are the dangers of premature birth
The hazards of premature birth are as follows:
1. The lungs of premature birth are incomplete and the lungs cannot completely expand, affecting normal breathing, leading to irregular breathing, prone to cyanophora, and even leading to death caused by hypoxia.
2. The liver is not well developed, which leads to insufficient synthesis of vitamin K in newborns. Then, when trauma and hypoxia infection or the coagulation mechanism is affected, bleeding will occur, and even severe pulmonary bleeding and intracranial hemorrhage will occur, resulting in serious consequences.
3 and . The central nervous system development is poor, and relatively speaking, the ability to self-regulate body temperature is poor, and it is prone to nodules and hard swelling in newborns.
4. It has poor attraction ability and is difficult to feed, which is easy to cause hypoglycemia. In severe cases, it is even necessary to feed through nasal feeding.
5. Premature babies have weak resistance and are prone to lung infection , and other symptoms. The incidence of
6 and jaundice will be higher, and the condition will be more serious.
7. The skin is thin and tender, the moisture content in the skin tissue is relatively high, and the depression is less subcutaneous fat .
8. Poor body temperature regulation ability and cannot change posture to reduce warm areas. In addition, the sweat glands are not mature, or the sweat glands are insufficiency, which can easily lead to excessive body temperature.
9. There is a risk of development and is prone to cerebral palsy, epilepsy, epilepsy, and easily occur, which can easily lead to cerebral palsy, epilepsy, etc.
10. The digestive function is relatively poor. During the feeding process, vomiting and milk suffocation will occur, which may even cause inhalation pneumonia , which will aggravate the symptoms of hypoxia.
