They appear very thin, because they haven't had time to put on fat. Most likely, their eyes are closed and they have no eyelashes. These tiny babies have little muscle tone, and most move very little.
Almost all require treatment with oxygen, surfactant, and mechanical assistance to help them breathe. These babies are too immature to suck, swallow, and breathe at the same time, so they must be fed through a vein intravenously until they develop these skills.
They often can't yet cry or you can't hear them due to the tube in their throat , and they sleep most of the day. Here's what to expect: Very preterm babies look quite similar to babies born earlier, but they're usually larger.
Most require treatment with oxygen, surfactant, and mechanical assistance to help them breathe. Some of these babies can be fed breast milk or formula through a tube threaded through their nose or mouth into the stomach, although others will need to be fed intravenously.
Some of these babies can cry. They can move more, although their movements may be jerky. They can grasp a finger and turn their head from side to side. These babies can open their eyes, and they begin to stay awake and alert for short periods. Outlook for a baby born at 32 to 33 weeks Weight: Between 3 pounds, 11 ounces 1.
Here's what to expect: Moderately preterm babies usually weigh less and appear thinner than full-term babies. They can sometimes breathe on their own, and many just need supplemental oxygen to help them breathe. They can sometimes be breastfed or bottle-fed. However, those who have breathing difficulties will probably need tube feeding. Outlook for a baby born at 34 to just under 37 weeks Weight: Between 4 pounds, 11 ounces 2 kg and 6 pounds, 7 ounces 3 kg Length: Between 17 inches 44 cm and 19 inches 48 cm Head circumference : Between 12 inches 31 cm and 13 inches 33 cm About 70 percent of preterm babies are born late preterm.
Here's what to expect: Late preterm babies may still appear thinner than full-term babies. These babies remain at higher risk than full-term babies for newborn health problems, including breathing and feeding problems, difficulties regulating body temperature, and jaundice. These problems are usually mild, and most babies make a quick recovery. Most of these babies can be breastfed or bottle-fed, although some especially those with mild breathing problems may need tube feeding for a brief time.
At around 35 weeks, babies have enough muscle tone to curl into a fetal position. Their grasp is now strong enough that they'll hang on while you lift them. These babies have more fluid and purposeful movements.
Some babies at this age are able to put their hands in their mouths for sucking. It's estimated that at 35 weeks gestation, the weight of the brain is only about 65 percent that of full-term infants.

When can my baby survive outside the womb? A short cervix can be an indicator that you're at higher risk for a preterm delivery. Your doctor may also order a cervical length measurement if your pregnancy is at high risk for cervical insufficiency because of a history of preterm birth, for example, or if you go to the hospital for symptoms of preterm labor.
If the ultrasound shows that your cervix is short, your provider may recommend that you cut back on physical activity and work, abstain from sex, and stop smoking if you haven't already. Depending on your situation and your baby's gestational age, you could have another ultrasound within the next few weeks. If you're less than 24 weeks pregnant and your cervix is shortening or dilating but you're not having any contractions, a cerclage may be recommended.
For this procedure, a band of strong thread is stitched around your cervix to help hold it closed. Your doctor may suggest a cerclage if you've had a history of possible cervical insufficiency or if you've had a preterm birth before 34 weeks.
The cerclage may be placed before there's cervical change or if shortening is noted. Alternately, depending on your specific case, vaginal progesterone may be offered, as it can reduce the risk of preterm delivery in women with a short cervix. Fetal fibronectin screening. This test is usually reserved for women who are having contractions or other symptoms of preterm labor. Fetal fibronectin fFN is a protein produced by the fetal membranes.
If more than a small amount turns up in a sample of your cervical and vaginal secretions between 24 and 34 weeks, you're considered to be at higher risk for preterm delivery. A positive fFN result might prompt your provider to give you drugs to hold off labor as well as corticosteroids to help your baby's lungs mature more quickly. However, the test is actually more accurate at telling you when you won't deliver than when you will.
If you have a negative fFN result, it's highly unlikely that you'll deliver in the next two weeks. A negative result can put your mind at ease and help you avoid hospitalization or other unnecessary treatment.
Talk with your doctor about medication. If you've previously had preterm premature rupture of the membranes PPROM or spontaneous preterm labor resulting in a preterm birth before 37 weeks and are currently carrying only one baby, talk to your provider about treatment with a progesterone compound called Makena 17 alpha hydroxyprogesterone caproate, or 17P for short.
Studies have shown that weekly injections of this hormone, starting at 16 to 20 weeks and continuing through 36 weeks, significantly reduce the risk of a repeat preterm delivery for women in this situation. In some cases, the medication is started later than 20 weeks.
It doesn't appear to offer any benefit to women carrying more than one baby or with no previous history of preterm labor. If you have signs of preterm labor or think you're leaking amniotic fluid, call your healthcare provider, who will probably have you go to the hospital for further assessment. You'll be monitored for contractions as your baby's heart rate is monitored, and you'll be examined to see whether your membranes have ruptured. Your urine will be checked for signs of infection, and cervical and vaginal cultures may be taken as well.
You may also be given a fetal fibronectin test. If your water hasn't broken, your provider will do a vaginal exam to assess the state of your cervix. An abdominal ultrasound will often be done as well, to check the amount of amniotic fluid present and confirm the baby's growth, gestational age, and position.
Finally, some providers will do a vaginal ultrasound to double-check the length of your cervix and look for signs of effacement. If all the tests are negative, your membranes haven't ruptured, your cervix hasn't dilated after a few hours of monitoring, your contractions have subsided, and you and your baby appear healthy, you'll most likely be sent home.
For about 3 in 10 women, preterm labor stops on its own. Although each provider may manage the situation a little differently, there are some general guidelines for handling preterm labor. If you're less than 34 weeks but 24 weeks or more pregnant and found to be in preterm labor, your membranes are intact, your baby's heart rate is reassuring, and you have no signs of a uterine infection or other problems such as severe preeclampsia or signs of a placental abruption , your practitioner will probably attempt to delay your delivery.
One way she can do this is by giving you special drugs called tocolytics. Tocolytics can delay delivery for up to 48 hours though they don't always work and are not routinely used. During that time, if your doctor thinks you're at risk of delivering within 7 days, your baby can be given corticosteroids drugs that cross the placenta to help his lungs and other organs develop faster. This will boost his chance of survival and minimizes some of the risks associated with an early birth.
Corticosteroids are most likely to help your baby when given between 24 and 34 weeks of pregnancy, but they're also given between 23 and 24 weeks. If you're less than 32 weeks pregnant and in preterm labor, and your provider thinks you're at risk of delivering in the next 24 hours, you may also be given magnesium sulfate to reduce the risk of cerebral palsy in your baby.
Cerebral palsy, a nervous system disorder, is associated with early preterm birth. This is done just in case a culture shows you're a carrier, as it takes 48 hours to get results.
To take advantage of technological advances in preterm care, a preterm infant is best cared for at a hospital with a neonatal intensive care unit NICU. If you're in a small community hospital where specialized neonatal care is not available for a preterm infant, you'll be transferred to a larger institution at this point, if possible.
Hospitals generally have limits for gestational how premature a baby they're able to care for. If you haven't reached 24 weeks, neither antibiotics for GBS prevention nor corticosteroids are recommended. Your medical team will counsel you about your baby's prognosis, and you can opt to wait or be induced. If your water breaks before 34 weeks but you're not having contractions, your medical team may decide to induce labor or may opt to wait, hoping to buy the baby more time to mature.
It depends on how far along you are and whether there's any sign of infection or other reason that your baby would be better off being delivered. In any case, unless you've had a recent negative GBS test, you'll be given antibiotics to protect against group B strep. If you're at 34 weeks or more, and your water had broken, you may be induced or delivered by cesarean section.
On the other hand, if you're less than 34 weeks pregnant, ACOG recommends waiting to deliver unless there's a clear reason to do otherwise. The purpose of waiting is to try to give your baby more time to mature.
The downside is a higher risk of infection. But at early gestational ages, the benefits of waiting usually outweigh the risks of an immediate induction or c-section. While waiting, you'll receive antibiotics for seven days, to lower the risk of infections and help prolong your pregnancy. You'll also receive a course of corticosteroids to help hasten your baby's lung development. You and your baby will be monitored carefully during this time.
Of course, if you develop symptoms of an infection or there are other signs that your baby is not thriving, you'll be induced or delivered by c-section. Premature babies may need to stay in the NICU until their medical problems resolve, they can feed well without issues, and they've grown big enough.

In general, infants that are born very early are not considered to be viable until after 24 weeks gestation.
This means that if you give birth to an infant before they are 24 weeks old, their chance of surviving is usually less than 50 percent. Some infants are born before 24 weeks gestation and do survive. But these infants have a very high chance of severe long-term health problems. About 40 percent of these preemies will suffer long-term health complications because they were born prematurely. Survival rates for infants born at 28 weeks gestation is between percent.
Babies born at 28 weeks old only have a 10 percent chance of having long-term health problems. Their chance of dying during infancy and childhood is also very low. Babies who are born after 34 weeks gestation have the same long-term health outcomes as babies who are delivered at full term 40 weeks.
In long-term follow-up, these infants do very well and usually are as healthy as non-preemies. On average, doctors recommend preemies stay in the NICU until three to four weeks before what their regular due date would have been. If we can work with you to delay your delivery by as little as one or two weeks, you baby will have a much higher chance of staying healthy as they grow. Researchers and obstetricians have studied for years if women can do anything to prevent preterm labor.
Because of this, no one intervention or treatment can prevent all preterm births. Recent studies have shown that treatment with a hormone named progesterone can lower the rate of preterm birth by as much as 30—50 percent. Progesterone is a steroid hormone.
