Gestational Age
Gestational age refers to the number of weeks of pregnancy. Many issues that affect newborns are related to the gestational age because it reflects the newborn's degree of physical maturity at birth.
The gestational age is determined by counting the number of weeks between the first day of the mother's last menstrual period and the day of delivery. This time frame may be adjusted according to other information doctors receive, including the results of early ultrasound scans, which give additional information regarding the gestational age. The estimate of the date a baby will be born (due date) is set at a gestational age of 40 weeks. The due date is an estimate, and only a small number of babies are born on that exact date. Most babies are born within a few weeks before or after the due date.
Newborns are classified by gestational age as
Full term: Delivered at 37 to before 42 weeks of gestation
Doctors also use the results of a physical examination and the physical features of the newborn (see sidebar Physical Features of a Premature Newborn Physical Features of a Premature Newborn ) to confirm gestational age.
Problems Before Birth
Problems in a newborn may have begun before birth.
Problems that develop before birth may be related to conditions in the mother that existed before the pregnancy or developed during the pregnancy, or to conditions in the fetus.

Diagnosis
Before birth, ultrasonography, blood tests, and sometimes imaging tests
After birth, various tests
Some problems in newborns may be diagnosed before birth if the mother is receiving regular prenatal care. Other problems are diagnosed after birth.
Diagnosing problems before birth is particularly helpful for fetuses with certain birth defects. Parents can plan with their doctor to deliver an infant in a hospital capable of providing a higher level of newborn care, including having a neonatal intensive care unit Neonatal intensive care unit (NICU) Problems in newborns may develop Before birth while the fetus is growing During labor and delivery After birth About 10% of newborns need some special care after birth due to prematurity, problems... read more (NICU).

Knowing the fetus's gestational age helps doctors track fetal growth and know what is normal at each stage of pregnancy. Identifying birth defects helps parents and doctors know what to expect, make plans for the pregnancy, and prepare for problems that could develop after birth. However, ultrasonography is not 100% accurate. Some babies are born with birth defects that were not detected with ultrasonography.
During pregnancy, a woman’s uterus will house and protect a developing fetus for about 9 months. Throughout the pregnancy, the development of the fetus can be monitored by routine ultrasounds.
An ultrasound is a procedure that allows a physician to examine internal anatomy through the use of high-frequency sound waves.
A transducer is placed against the skin of the abdomen and gently moved around while it emits harmless sound waves into the body. The sound waves reflect, or echo, off structures within the abdomen, such as the fetus. The sound wave signals are interpreted by a computer and displayed on a monitor. With these images, the physician can examine the fetus and evaluate the progress of its development.
There are several types of screening blood tests that can be done to detect genetic and other abnormalities in the fetus during pregnancy. These are usually done during the first or second trimester. One type of blood test is called cell-free fetal nucleic acid (cfDNA). For the cfDNA test, small fragments of the fetus's DNA, which are present in the pregnant woman's blood in tiny amounts, are analyzed. The test results may be abnormal if the fetus has a genetic abnormality such as Down syndrome Down Syndrome (Trisomy 21) Down syndrome is a chromosome disorder caused by an extra chromosome 21 that results in intellectual disability and physical abnormalities.

If the ultrasound and blood test results indicate a possible problem with the fetus, doctors may do additional tests on cells from the fetus using samples taken with a needle from the amniotic fluid (amniocentesis Amniocentesis Prenatal testing for genetic disorders and birth defects involves testing a pregnant woman or fetus before birth (prenatally) to determine whether the fetus has certain abnormalities, including... read more ), placenta (chorionic villus sampling Chorionic Villus Sampling Prenatal testing for genetic disorders and birth defects involves testing a pregnant woman or fetus before birth (prenatally) to determine whether the fetus has certain abnormalities, including... read more ), or the umbilical cord (percutaneous umbilical blood sampling Percutaneous Umbilical Blood Sampling Prenatal testing for genetic disorders and birth defects involves testing a pregnant woman or fetus before birth (prenatally) to determine whether the fetus has certain abnormalities, including... read more [cordocentesis]).

MRI may give additional information about an abnormality and can be useful in evaluating treatment options.
Fetoscopy is an invasive test that is rarely done. For this test, doctors insert a small viewing scope (endoscope) into the womb. Early in pregnancy, the scope may be inserted through the mother's cervix. Later in pregnancy, the scope is inserted through a small incision in the mother's abdomen and then another incision in the uterus. The scope lets doctors take a direct look at the placenta and fetus to identify (and sometimes treat) disorders in the fetus.

Additional testing may also be needed if the newborn is outside the normal range of weight or size. Newborns are classified into three groups by how much they weigh compared to other newborns of the same gestational age. The three groups are
Appropriate for gestational age (AGA): From the 10th to the 90th percentile of weight, meaning they are among the 82 babies in the middle range for weight
Small for gestational age Small-for-Gestational-Age (SGA) Newborns A newborn who weighs less than 90% of newborns of the same gestational age at birth (below the 10th percentile) is considered small for gestational age. Newborns may be small because their parents... read more (SGA): Less than the 10th percentile of weight, meaning they are among the 9 lowest-weight babies out of 100 born at a particular gestational age

Newborns may be large because the parents... read more (LGA): Greater than the 90th percentile of weight, meaning they are among the 9 heaviest babies out of 100 born at a particular gestational age
The gestational age and weight classifications help doctors determine the risk of various complications. For example, preterm newborns are at increased risk of breathing problems because their lungs may not be fully developed. Large-for-gestational-age newborns may be at increased risk of low blood sugar (glucose).
Treatment
Medical treatment of specific disorders in newborns is discussed elsewhere.
Many health issues in newborns are minor and resolve on their own or need follow-up care at a doctor's office in the weeks after birth. Some newborns have more severe issues. Newborns (neonates) that are preterm or have serious health issues are cared for in a neonatal intensive care unit (NICU), where this level of care is available.
Neonatal intensive care unit (NICU)
The NICU is a specialized facility that brings together the medical team and technology needed to care for newborns with various disorders. Newborns may need such specialized care because of
Respiratory disorders
Low blood sugar (glucose)
The NICU team is usually directed by neonatologists (pediatricians specially trained to manage the problems of newborns). Much of the care is delivered by specialized neonatal nurses. Other team members may include pediatricians, respiratory therapists, social workers, pharmacists, physical and occupational therapists, speech-language pathologists, and other specialized personnel. Many NICUs also have doctors and students in training. Depending on the care required for the newborn, medical and surgical subspecialist physicians are also often involved.
In the NICU, newborns are cared for in incubators or radiant warmers, which keep them warm while allowing staff to observe and treat them. Newborns are usually connected to monitors that continuously measure their heart rate, breathing, blood pressure, and oxygen levels in the blood. They may have catheters placed inside an artery or in the vein running inside the umbilical cord to permit continuous blood pressure monitoring, to allow repeated blood sampling, and to give fluids and medications.
NICU facilities vary widely. Some NICUs have wards in which many babies share a large space, some have modules with a few babies in a space, and some have private rooms for a family and their baby. Regardless of the layout, NICU personnel are focused on meeting the parents’ need for time and privacy to become acquainted with their newborn; to learn the newborn’s personality, likes, and dislikes; and ultimately to learn any special care that they will need to provide at home. Visiting hours vary but are usually flexible so that families can spend as much time with their newborn as they wish. Some hospitals have sleeping facilities for parents on-site or nearby. Many NICUs have cameras, which allows parents to see their baby even when they cannot be present in the NICU.
Sometimes, parents feel that they have little to offer their newborn in a NICU. However, their presence, including physical contact, speaking, and singing to their newborn, is very important. Newborns hear their parents' voices even before birth and are accustomed to them so they often respond better to their own parents’ attempts to calm them. Skin-to-skin contact (also called kangaroo care), in which the newborn is allowed to lie directly on a parent’s chest, is comforting to the newborn and enhances bonding.

NICU personnel strongly encourage mothers to breastfeed directly or provide breast milk in a bottle when their infant's condition permits. Depending on their gestational age and medical problems, infants in a NICU may not be able to breastfeed or drink breast milk from a bottle, but, in most cases, they can still receive breast milk through a feeding tube that is placed in their nose and goes to their stomach. Preterm infants are not able to suck adequately and are not able to coordinate sucking, swallowing, and breathing. Full-term infants in the NICU may have respiratory problems or other illnesses that make breastfeeding impossible. But, because breast milk is clearly the best food for newborns, mothers are encouraged to pump their breast milk so it can be given to their baby through a feeding tube or saved for later use.
NICU personnel understand that parents need to be kept up to date on their baby's condition and expected course, the care plan, and the estimated time of discharge. Regular discussions with the nurses and medical team are beneficial. Many NICUs also have social workers who help communicate with the parents and assist in arranging family and medical services.
