Postterm is diagnosed based on the neonate's gestational age Gestational Age Gestational age and growth parameters help identify the risk of neonatal pathology.
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 Mechanical Ventilation Initial stabilization maneuvers include mild tactile stimulation, head positioning, and suctioning of the mouth and nose followed as needed by Supplemental oxygen Continuous positive airway 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 Extracorporeal Membrane Oxygenation ECMO Initial stabilization maneuvers include mild tactile stimulation, head positioning, and suctioning of the mouth and nose followed as needed by Supplemental oxygen Continuous positive airway ECMO is available in a relatively few neonatal centers and is reserved for infants with hypoxic respiratory failure refractory to conventional medical treatment.
Persistent pulmonary hypertension is treated with supportive therapies and inhaled nitric oxide or other pulmonary vasodilators. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

Perinatal Problems. Test your knowledge. Meconium aspiration syndrome may be unusually severe because amniotic fluid volume is decreased and thus the aspirated meconium is less dilute. Persistent pulmonary hypertension Persistent Pulmonary Hypertension of the Newborn Persistent pulmonary hypertension of the newborn is the persistence of or reversion to pulmonary arteriolar constriction, causing a severe reduction in pulmonary blood flow and right-to-left 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 Gestational Age Gestational age and growth parameters help identify the risk of neonatal pathology. Gestational age is the primary determinant of organ maturity. Gestational age is loosely defined as the number Postterm is diagnosed based on the neonate's gestational age Gestational Age Gestational age and growth parameters help identify the risk of neonatal pathology.
