postheadericon Preterm Labor Pregnancy and Birth (II)

A birth weight baby can say that is appropriate for gestational age (AGA) or small for gestational age (SGA). Small babies can be small because they are premature or small they are “growth retarded” or “limited growth.” A baby can be both premature and small for gestational age.

If two children are the same weight at birth, but one born at 33 weeks and is the right weight for this gestational age and the other is a growth restricted baby was born at 38 weeks, in general, the older child will have an easier time adaptation to life outside the womb. If a baby is great, but was born early, you may still have the problems associated with early birth. the baby will have the most problems is that it is a bit premature and small for gestational age.

Before delivery when the baby can be physically examined to determine gestational age, date of first day of last menstrual period is the best single piece of information regarding the duration of pregnancy. When a woman does not remember that date, when you have irregular periods or get pregnant after the removal of a method of birth control that made her stop periods, such as Depo-Provera (the “fire”), a test ultrasound determines the duration of pregnancy.

Ultrasound can also be invoked when the uterine size does not match the dates. Ultrasound can be repeated to determine if the difference in uterine size and menstrual dates (call dates discrepancy in size) is that the baby grows too big or growing well, or if in fact the baby is growing as expected, only older or younger than the dates suggest. Serial ultrasounds done several weeks apart, can measure the rate of fetal growth. good growth, can also be determined by a variety of ultrasound measurements to assess the relationship of head size, for example, the size of the abdomen. If there is a large discrepancy between these two, the baby may be growing due.
