During a pregnancy, the baby grows in the mother's uterus (womb) usually for 38 to 40 weeks. When a baby is born prematurely (too early), the baby may require special medical care. The level of extra care needed often depends on how early the birth occurs. Premature babies weigh much less than full-term infants because they have not had the full amount of time for growth inside the uterus.
Babies born very early in pregnancy are extremely small and fragile. They may weigh less than 2 pounds. They require specialized intensive care in a neonatal intensive care unit (NICU). Doctors and nurses who work in NICUs have specialized education to care for premature infants and their problems. Equipment in a NICU, such as incubators and ventilators, is made especially for premature infants and their special needs. Health problems for babies who are born prematurely may not end when the baby goes home from the hospital. They may need special medical care as they grow older.
The February 12, 2003, issue of JAMA includes an article about children who were
Inability to breathe or breathe regularly on their own, possibly
requiring oxygen and a ventilator
Bradycardia (low heart rate)
Body temperature regulation (the baby cannot maintain his or
her own body heat)
Feeding and growth problems because of an immature digestive system
Jaundice (yellowing of skin and possible brain damage
due to buildup of bilirubin, a blood breakdown product)
Anemia (not enough red blood cells to carry oxygen to tissues)
Apnea, episodes of stopping breathing, which may
require special monitoring, even at home
Bronchopulmonary dysplasia, a chronic lung disease
that may or may not improve as the child grows
Hearing or vision problems related to immature nerves or treatment
Developmental delay and learning disabilities from brain damage
related to immaturity
Because premature babies can be very ill, especially extremely premature
infants, decisions about treatments can be difficult for parents, doctors,
and nurses. Medical research studies provide information about treatments
and the likely course of an illness, but they cannot predict how each baby
will recover from being born too early. Preventing premature birth is important.
Regular prenatal (before birth) medical care, avoiding any exposure to tobacco
smoke, avoiding alcohol and illegal substances, and control of chronic medical
problems are all ways that women can help maintain a healthy pregnancy to
the full term.
