Read about various factors that can contribute to premature labour, such as smoking and infections. Steps can be taken to avoid premature labour. Preterm birth, or premature birth, is usually an unplanned event. Depending on the causes of the birth and how premature the baby is, it may also be an emergency. This section explores the causes of premature birth, the signs of premature birth, and strategies to delay premature birth.

Scientists have found evidence that the cox-2 inhibitor celecoxib, a common pain reliever used to treat arthritis, may offer a new way to reduce the risk of the most common cause of brain damage in babies born prematurely. The work involves shoring up blood vessels in a part of the brain that in premature infants is extremely fragile and vulnerable to dangerous bleeding, which affects an estimated 12, children a year, leaving many permanently affected by cerebral palsy, mental retardation, and seizures.

A research article describing the work appeared in the April issue of Nature Medicine , which included a cover photograph taken by the Rochester team showing the brain cells involved in the brain damage seen in some premature infants. The research is based on extensive brain studies of infants who died prematurely as well as on findings with newborn rabbits, whose brains resemble those of premature babies in some very important ways.

The medication would need to be tested rigorously in pregnant women before being considered as a treatment for their babies. But the investigators point out that celecoxib is already used widely in people, including pregnant women, making a clinical trial in people feasible. The researchers focused on a part of the brain known in developing infants as the germinal matrix, a temporary structure that is the birthplace of all brain cells in an infant.

The germinal matrix is designed to be active until around week 36 of gestation. Then, with most of the infrastructure of the brain in place, the germinal matrix disintegrates and shrinks into a much smaller brain region known as the ventricular zone in adults. The problem is that the germinal matrix is as fragile as it is crucial during its brief existence.

In a normally developing fetus, the blood vessels do their job and then disappear by the time the baby is born. But when a baby is born prematurely, the structure is suddenly thrust into a role for which it is not designed, handling high rates of blood flow and pressure. In the case of a bleed, the blood vessels break, cutting off the supply of oxygen to some brain tissue and directly damaging parts of the brain. Babies most at risk are those born between 24 and 32 weeks gestation that weigh less than grams, or about 3 lbs.

About 20 percent of such infants have a bleed, known as a germinal matrix hemorrhage or an intraventricular hemorrhage. While the problem sometimes is very small and hardly noticeable, other times the bleed causes tremendous brain damage. The goal was to make the germinal matrix a little hardier in cases of premature birth, by eliminating the active building of new, but very fragile, blood vessels that bleed more easily than established blood vessels. The team used celecoxib to knock down the production of cox-2, which in turn slowed production of VEGF.

The team also studied an anti-cancer drug known as ZD, which affects another molecule, angiopoietin-2, that the body uses to build blood vessels. The team found that in human brain tissue, the compounds greatly reduced the production of cells used to build blood vessels, and decreased levels of angiopoietin-2 and VEGF, the two molecules very active in building new blood vessels.

Results were dramatic in female rabbits that were given the drugs for two days before delivering their offspring prematurely. The team showed that celecoxib cut the risk in offspring of having a moderate or severe bleed in half, from 90 percent to 45 percent.

The percentage was reduced even more when ZD was used as well, from 45 to 27 percent, but Nedergaard and Ballabh point out that ZD is a very potent medication not likely to be given to pregnant women in the near future.

Overall, the best way to prevent the problem, doctors say, is to do everything possible to allow a pregnant woman to carry a pregnancy for a full 40 weeks. So doctors put a great deal of effort into preventing preterm labor. Steroids, commonly used to help develop the lungs of a premature infant, can help prevent bleeds too. And recent research has shown that indomethacin, which like celecoxib is a non-steroidal anti-inflammatory drug, has been shown to help prevent such bleeds and is used to treat premature infants for other problems, but it has some severe side effects, Ballabh said.

And a report by researchers at Washington University and Northwestern University indicated that celecoxib — the same drug that Nedergaard and Ballabh showed helps prevent the bleeds — might also be effective in preventing preterm labor. Right now there is nothing available that has been shown to be really effective at preventing this problem.

For example, the brain, lungs, and liver need the final weeks of pregnancy to fully develop. Taking your baby home Your baby is ready to go home when he or she: Can breathe without support Can maintain a stable body temperature Can breast- or bottle-feed Is gaining weight steadily Is free of infection In some cases, a child may be allowed to go home before meeting one of these requirements — as long as the baby's medical team and family create and agree on a plan for home care and monitoring. Contrary to expectations, confining the mother to bed rest does not help to prevent preterm birth. Public Health Grand Rounds. The only preventive drug therapy is progesterone pronounced proh-JES-tuh-rohn , a hormone produced by the body during pregnancy, which is given to women at risk of preterm birth, such as those with a prior preterm birth. This preventive therapy is given beginning at 16 weeks of gestation and continues to 37 weeks of gestation.

Pregnant women should avoid alcohol and tobacco. In addition, they should take no drug or medicine without first consulting their doctors. Illicit drugs can be particularly harmful to a developing baby and may decrease its chance of survival.

Illicit drug use by pregnant women can cause serious health problems for the unborn baby. Here is a list of some illicit drugs and the effects they can have on a fetus:. If you use drugs, so does your baby. Drugs can affect a baby before and after birth. After a baby is born, drugs can be passed from mother to baby through her breast milk.

Pregnancy: Avoiding Substance and Drug Abuse The effects that various illicit drugs can have on an unborn child are listed. Appointments How can illicit drugs harm my baby? Here is a list of some illicit drugs and the effects they can have on a fetus: Amphetamines: The use of these drugs has been linked to heart defects in babies born to women who used them.

These drugs taken during pregnancy may increase the risk of placental problems as well as miscarriage and preterm birth. These babies may also be of low birth weight. Amphetamines are often sold as a street drug, but the main ingredient in amphetamines can be found in many over-the-counter diet pills.

Cocaine: Cocaine use can cause contractions of the uterus, which might lead to bleeding complications or premature labor. Cocaine can cause stillbirth, miscarriage, preterm birth, growth retardation, and birth defects in babies. Marijuana: Women who smoke marijuana during their pregnancies might have babies with problems, including impaired fetal growth.

Marijuana increases the risk of having a miscarriage, preterm birth, a baby with low birth weight, developmental delays, and even learning problems. These smaller babies are more likely to have health problems than are babies born to women who did not use marijuana. Narcotics: Drugs such as heroin can cause growth problems, premature labor, and a fetal syndrome of narcotic withdrawal after birth. In addition, sudden infant death syndrome SIDS is more likely among babies whose mothers used narcotics during pregnancy.

Tranquilizers: Tranquilizers including Valium have been associated with birth defects. Mothers who engage in heavy use during pregnancy can also have babies who undergo withdrawal symptoms after birth. Glues and solvents: Women who sniff fumes during pregnancy may suffer a miscarriage or preterm labor and birth.

They can have babies with birth defects including low weight, short height, joint and limb problems, heart defects, and abnormal facial features. Ecstasy: Pregnant women who use this drug might have babies with long-term learning and memory problems. Remember… If you use drugs, so does your baby. Show More.
