Post mature babies-Postterm and Postmature Infants - Pediatrics - MSD Manual Professional Edition

Postterm pregnancy is the condition of a woman who has not yet delivered her baby after 42 weeks of gestation , two weeks beyond the median duration of a human pregnancy of about 40 weeks mean duration of pregnancy varies by parity. After the 42nd week of gestation, the placenta , which supplies the baby with nutrients and oxygen from the mother, starts aging and will eventually fail. Some conditions are associated with postterm pregnancy. For example, meconium aspiration syndrome is a condition when the fetus passes its fecal matter , which is not typical until after birth, and breathes it in. Postterm pregnancy may be a reason to induce labor.

A postterm infant is an infant born after 42 weeks gestation. A postmature infant is a postterm infant with manifestations of dysmaturity. The cause of postmaturity is generally unknown, but previous postterm delivery increases the risk 2- to 3-fold. Postmaturity may be caused by abnormalities that affect the fetal pituitary-adrenal axis eg, anencephaly , adrenal gland hypoplasia, congenital adrenal hyperplasia and by x-linked ichthyosis associated with placental sulfatase deficiency.

However, in some cases, the placenta involutes as pregnancy progresses and multiple infarcts and villous degeneration develop, causing placental insufficiency. In these cases, the fetus receives inadequate nutrients and oxygen from the mother, resulting in a thin due to soft-tissue wasting , undernourished infant with depleted glycogen stores and decreased amniotic fluid volume. Such infants are dysmature and, depending on when placental insufficiency develops and the severity of the condition, they may be small-for-gestational-age.

Meconium aspiration syndrome. Perinatal asphyxia may result from placental insufficiency as well as cord compression secondary to oligohydramnios. Meconium aspiration syndrome may be unusually severe because amniotic fluid volume is decreased and thus the aspirated meconium is less dilute. Persistent pulmonary hypertension often occurs after meconium aspiration. Neonatal hypoglycemia is a complication caused by insufficient glycogen stores at birth.

Because anaerobic metabolism rapidly uses the remaining glycogen stores, hypoglycemia is exaggerated if perinatal asphyxia has occurred. Postmature infants are alert and appear mature. They have a decreased amount of soft-tissue mass, particularly subcutaneous fat.

The skin may hang loosely on the extremities and is often dry and peeling. The fingernails and toenails are long. The nails and umbilical cord may be stained with meconium passed in utero. For postterm infants, gestational age. Postterm is diagnosed based on the neonate's gestational age. Improved obstetric care over the past two decades has markedly decreased the number of infants delivered past 41 weeks gestation, which has also decreased the incidence of meconium aspiration syndrome.

Postmature and dysmature infants are at risk of hypoglycemia and should be monitored and managed accordingly. For infants with perinatal asphyxia, management depends on the severity of the disease process.

Neither the incidence nor the severity of meconium aspiration syndrome is reduced by endotracheal suction at the time of delivery, regardless of the apparent viscosity of the fluid or the infant's level of activity, so endotracheal intubation should be reserved for infants who need ventilatory assistance. Infants with meconium aspiration syndrome may require assisted ventilation; high-frequency ventilation is sometimes helpful. Sedation is often necessary. Surfactant treatment does not decrease overall mortality but does reduce the likelihood of the need for treatment with extracorporeal membrane oxygenation ECMO , so surfactant is frequently used in infants with significant respiratory distress.

ECMO is available in a relatively few neonatal centers and is reserved for infants with hypoxic respiratory failure refractory to conventional medical treatment.

Postterm pregnancy - Wikipedia

Postterm pregnancy is the condition of a woman who has not yet delivered her baby after 42 weeks of gestation , two weeks beyond the median duration of a human pregnancy of about 40 weeks mean duration of pregnancy varies by parity.

After the 42nd week of gestation, the placenta , which supplies the baby with nutrients and oxygen from the mother, starts aging and will eventually fail. Some conditions are associated with postterm pregnancy. For example, meconium aspiration syndrome is a condition when the fetus passes its fecal matter , which is not typical until after birth, and breathes it in. Postterm pregnancy may be a reason to induce labor. The management of labor and delivery may vary depending on the gestational age.

It is common to encounter the following terms when describing different time periods of pregnancy. Postterm pregnancy should not be confused with postmaturity, postmaturity syndrome, or dysmaturity. These terms describe the neonatal condition that may be caused by postterm pregnancy instead of the duration of pregnancy. Due dates are easily miscalculated when the mother is unsure of her last menstrual period.

When there is a miscalculation, the baby could be delivered before or after the expected due date. When the menstrual period is irregular it is very difficult to judge when the ovaries would be available for fertilization and subsequent pregnancy.

Some post-mature pregnancies may not be post-mature in reality due to the uncertainty of mother's last menstrual period. Because postterm pregnancy is a condition solely based on gestational age, there are no confirming physical signs or symptoms. While it is difficult to determine gestational age physically, infants that are born postterm may be associated with a physical condition called postmaturity.

Doctors diagnose postmature birth based on the baby's physical appearance and the length of the mother's pregnancy. Once a pregnancy is diagnosed postterm, usually at or greater than 42 weeks of gestational age , the mother should be offered additional monitoring as this can provide valuable clues that the fetal health is being maintained.

Regular movements of the fetus is the best sign indicating that it is still in good health. The mother should keep a "kick-chart" to record the movements of her fetus. If there is a reduction in the number of movements it could indicate placental deterioration. Doppler fetal monitor is a hand-held device that is routinely used in prenatal care.

When it is used correctly, it can quickly measure the fetal heart rate. The baseline of fetal heart rate is typically between and beats per minute. Doppler flow study is a type of ultrasound that measures the amount of blood flowing in and out of the placenta. Usually, a red color indicates a flow toward the ultrasound transducer, while blue indicates a flow away from the transducer. Based on the display, doctors can evaluate blood flow to the umbilical arteries, umbilical veins, or other organs such as heart and brain.

Nonstress test NST is a type of electronic fetal monitoring that uses a cardiotocograph to monitor fetal heartbeat, fetal movement and mother's contraction. NST is typically monitored for at least 20 minutes. Signs of a reactive normal NST include a baseline fetal heart rate FHR between and beats per minute bpm and 2 accelerations of FHR of at least 15 bpm above baseline for over 15 seconds.

Vibroacoustic stimulation and longer monitoring may be needed if NST is non-reactive. A biophysical profile is a noninvasive procedure that uses the ultrasound to evaluate the fetal health based on NST and four ultrasound parameters: fetal movement, fetal breathing, fetal muscle tone, and the amount of amniotic fluid surrounding the fetus. Therefore, a score of 0 points for amniotic fluid may indicate the fetus is at risk.

A woman who has reached 42 weeks of pregnancy is likely to be offered induction of labour. Alternatively, she can choose expectant management, that is, she waits for the natural onset of labour. Women opting for expectant management may also choose to carry on with additional monitoring of their baby, with regular CTG, ultrasound, and biophysical profile.

Risks of expectant management vary between studies. Inducing labor artificially starts the labor process by using medication and other techniques. Labor is usually only induced if there is potential danger on the mother or child. Sometimes mothers will request to be induced for reasons that are not medical. This is called an elective induction. Doctors try to avoid inducing labor unless it is completely necessary. There are four common methods of starting contractions. A doctor inserts a finger into the mother's cervix and moves it around to separate the membrane connecting the amniotic sac, which houses the baby, from the walls of the uterus.

It may have to be done several times before the stimulant hormone is released, and contractions start. The doctor uses a plastic hook to break the membrane and rupture the amniotic sac.

Within a few hours labor usually begins. The drug Cervidil is administered by mouth in tablet form or in gel form as an insert. The hormone oxytocin is usually given in the synthetic form of Pitocin. It is administered through an IV throughout the labor process. This hormone stimulates contractions. Pitocin is also used to "restart" labor when it's lagging. Prevalence of postterm pregnancy may vary between countries due to different population characteristics or medical management.

Factors include number of first-time pregnancies, genetic predisposition, timing of ultrasound assessment, and Caesarian section rates, etc. From Wikipedia, the free encyclopedia.
