What is the normal process of labor? • In the first stage of labor contractions occur about every 8 to 10 minutes, increasing in frequency, duration, and intensity until the mother’s cervix expands. In the second stage of labor, which lasts about 90 minutes, the baby begins to move through the cervix and birth canal and ultimately leaves the mother’s body. In the third stage of labor, which lasts only a few minutes, the umbilical cord and placenta are expelled from the mother. • After it emerges, the newborn, or neonate, is usually inspected for irregularities, cleaned, and returned to its mother and father. • Parents-to-be have a variety of choices regarding the setting for the birth, medical attendants, and whether or not to use pain-reducing medication. Sometimes, medical intervention, such as Cesarean birth, becomes necessary. 2. What complications can occur at birth, and what are their causes, effects, and treatments? • Preterm, or premature, infants, born less than 38 weeks following conception, generally have low birthweight, which can cause chilling, vulnerability to infection, respiratory distress syndrome, and hypersensitivity to environmental stimuli. They may even show adverse effects later in life, including slowed development, learning disabilities, behavior disorders, below-average IQ scores, and problems with physical coordination. • Very-low-birthweight infants are in special danger because of the immaturity of their organ systems. However, medical advances have pushed the age of viability of the infant back to about 24 weeks following conception. • Postmature babies, who spend extra time in their mothers’ wombs, are also at risk. However, physicians can artificially induce labor or perform a Cesarean delivery to address this situation. Cesarean deliveries are performed when the fetus is in distress, in the wrong position, or unable to progress through the birth canal. • The infant mortality rate in the United States is higher than the rate in many other countries, and higher for low-income families than higher-income families. • Postpartum depression, an enduring, deep feeling of sadness, affects about 10% of new mothers. In severe cases, its effects can be harmful to the mother and the child, and aggressive treatment may be employed. 3. What capabilities does the newborn have? • Human newborns quickly master breathing through the lungs, and they are equipped with reflexes to help them eat, swallow, find food, and avoid unpleasant stimuli. Their sensory capabilities are also sophisticated [Show More]
