It's not a big deal, is it

summary

How many people really know about full-term children? Term small sample infants generally refer to a group of newborns whose birth weight is lower than the 10th percentile of the average weight of infants of the same gestational age, or two standard deviations lower than the average weight. There are premature, full-term and expired small sample. The birth weight of full-term small sample infants is less than 2500g, which is the most common in small sample infants. Small sample infants may be the result of fetal intrauterine growth restriction, and some of them belong to healthy newborns with small growth and development. This kind of baby has enough gestational age, but the ability is low after birth, prone to meconium aspiration, hypothermia, polycythemia, hypoglycemia, intrauterine infection and other congenital abnormalities. Let's take a look at the following.

It's not a big deal, is it

First, the birth weight is lower than the average weight of the same gestational age infants, especially the development, neurobehavioral and mental retardation, and the mortality of small sample infants is 8 times of that of normal full-term infants. Therefore, the treatment of small sample infants has been paid attention recently, and the mother, placenta, fetus and other factors can cause small sample infants.

Second: placental implantation position is not good, abnormal vascular communication, chorionic inflammation, avascular chorionic villi, chorionic ischemic necrosis, multiple placental infarction, placental abruption, single umbilical artery, contour placenta, congenital metabolic abnormalities and syndromes: such as insulin-like growth factor, islet like growth factor binding protein.

Third: the mother is short and normal. The pregnant mother is too old or too young, the mother's malnutrition at the time of conception and the mother's malnutrition during pregnancy. Maternal chronic diseases: primary hypertension, hypertensive disorder complicating pregnancy, microangiopathy in maternal diabetes mellitus, severe cyanotic congenital heart disease and sickle cell anemia, etc.

matters needing attention

Strengthen the health care of pregnant women, avoid all factors that are not conducive to fetal growth. Timely treatment of maternal complications such as pregnancy induced hypertension, strengthen fetal intrauterine monitoring, timely detection of fetal intrauterine growth retardation, and treatment of pregnant women.
