Survival rate of premature infants born at 32 weeks of gestation

The fetus at 32 weeks of pregnancy is not yet fully developed. The survival rate of the fetus born at this stage is relatively low, and the mother needs to take extra careful care of it. Premature babies also have many congenital diseases. It is best to let the doctor check the baby's body clearly at birth, and then pay attention to strengthening the baby's nutritional supplements. Under normal circumstances, the survival rate of premature babies born at 32 weeks of gestation can reach about 70%, but parents need to spend more energy to take care of them.

Premature babies born at 32 weeks of gestation need to be breastfed. For premature babies, the nutrients and amino acids contained in mother's milk are more than those in full-term breast milk, which can well meet the nutritional needs of premature babies. At the same time, the milk secreted by premature mothers can be better digested and absorbed by premature babies, while improving the immunity of premature babies, which is helpful for better fighting infection.

There are obvious differences in the physical condition of each baby. After all, the baby's nutritional absorption and overall growth and development within 32 weeks are different. So it is not 100% guaranteed that every premature baby will survive after delivery. The final survival rate of premature babies will vary from person to person, and there is no standard survival rate of 100%. Just in terms of the overall survival rate, premature babies born at 32 weeks can achieve a survival rate of 70%.

Types of premature babies

Newborns with a birth weight between 1500 and 2500 grams or delivered at a gestational age of 30 weeks. Thanks to medical advances, almost all babies in this group now survive without complications and generally develop well.

Neonates with a birth weight between 1000 and 1500 grams or delivered between the 27th and 30th weeks of gestation. The survival rate for this group is nearly 90%, but among surviving newborns, 10% to 15% suffer from neurological disorders during development, most of which require treatment.

Newborns with a birth weight of less than 1000 grams or a gestational age of less than 27 weeks. The survival rate of this group, especially in newborns weighing 800 to 1000 grams, is about 70% to 80%. The decisive factor for survival depends on whether there is a high level of rescue measures after delivery. Among newborns weighing less than 800 grams, 20% have physical and mental developmental disabilities, and the survival rate is only 50%, and some may even suffer from long-term neurological diseases.

Factors that contribute to premature birth

1. Pregnancy complications: Complications such as gestational diabetes, preeclampsia, polyhydramnios, problematic placenta, placenta previa and placental abruption make early delivery more likely.

2. Structural abnormalities of the uterus and cervix: A uterus that is malformed, very large, or has other structural abnormalities can make it more difficult to carry a baby for a long time - which can be related to problems with the cervix.

3. Gum infection: Periodontal disease, to which pregnant women are more susceptible due to the effects of pregnancy hormones, has been linked to premature birth. Some experts suspect that bacteria that cause inflammation in the gums can actually enter the bloodstream, reach the fetus, and initiate early delivery. Other studies have raised another possibility: Bacteria that cause inflammation in the gums can also trigger the immune system to produce inflammation in the cervix and uterus, triggering early labor.

4. Stress levels: Researchers believe that severe psychological stress may lead to the release of hormones that trigger uterine contractions and premature birth.

5. Occupational factors: Extreme physical work stress is also associated with premature birth. Researchers found that pregnant women who stood for long periods of time or whose jobs were very physically strenuous were more likely to deliver early.

6. Uterine and vaginal infections during pregnancy: Infections, both in the reproductive tract - such as bacterial vaginosis - and those in the uterus and amniotic fluid, are thought to be responsible for nearly half of all premature births. Experts suspect the infection caused inflammation, which led to the release of prostaglandins - the same substances that are released when pregnant women start labor at term. Treating a urinary tract infection can also induce premature labor.
