Amniotic fluid surrounding your baby

Friday, July 26th, 2013

insideWhat is this made of and how much is enough, too much? What’s normal, what’s not?

The amniotic sac that contains your baby begins to form about 12 days after conception. Amniotic fluid begins to form at that time, too. In the early weeks of pregnancy, amniotic fluid is mainly made up of water supplied by the mother. After about 12 weeks, your baby’s urine makes up most of the fluid. The amount of amniotic fluid increases until about 36 weeks of pregnancy. At that time you have about 1 quart of fluid. After that time, the level begins to decrease.

Sometimes you can have too little or too much amniotic fluid. Too little fluid is called oligohydramnios. Too much fluid is called polyhydramnios. Either one can cause problems for a pregnant woman and her baby. Even with these conditions, though, most babies are born healthy.

The amniotic fluid that surrounds your baby plays an important role in her growth and development. This clear-colored liquid protects the baby and provides her with fluids. Your baby actually breathes this fluid into her lungs and swallows it. This helps her lungs and digestive system grow strong. Your amniotic fluid also allows your baby to move around, which helps her to develop her muscles and bones.

Normal amniotic fluid is clear or tinted yellow. Fluid that looks green or brown usually means that the baby has passed his first bowel movement (meconium) while in the womb. (Most babies have their first bowel movement after birth.)

If the baby passes meconium in the womb, it can get into his lungs through the amniotic fluid. This can cause serious breathing problems, called meconium aspiration syndrome, especially if the fluid is thick. Some babies with meconium in the amniotic fluid may need treatment right away after birth to prevent breathing problems. Babies who appear healthy at birth may not need treatment, even if the amniotic fluid has meconium.

Fetal scalp pH testing

Wednesday, January 9th, 2013

Fetal scalp blood sampling is a quick test your health care provider can use to check if your baby is getting enough oxygen during labor.

Sometimes fetal heart monitoring doesn’t provide enough information about how the baby is doing with the stress of labor. In these cases, testing the scalp pH can help the health care provider decide whether the baby is getting enough oxygen during labor. This helps the provider decide if the baby is healthy enough to continue labor on its own, or if a faster delivery with forceps or a cesarean section might be a better route to take.

During labor, a woman’s cervix, the opening of the uterus, thins and opens to let her baby pass through the vagina. In order to have fetal scalp blood sampling, the cervix must be dilated enough that the provider can reach the baby’s head.

The test may remind you of a pelvic exam. It takes about 5 minutes. The woman lies on her back with her feet in stirrups. The provider places a plastic cone in the vagina that fits up against the baby’s head. The provider pricks the baby’s scalp and takes a small amount of blood. The blood is tested, and results are ready in just a few minutes.

If mom has an infection, like HIV or hepatitis C, her provider may not recommend fetal blood sampling. This is because she can pass these infections to her baby through the spot where his scalp is pricked.

What is a fetal nonstress test?

Tuesday, October 2nd, 2012

The nonstress test is a way of monitoring your baby’s health through your skin. This is not an invasive test, meaning it is not performed internally. A nonstress test allows your health care provider to check if your baby’s heart rate pattern is one seen in healthy babies. It checks to see that the heart rate increases when the baby moves around.

The nonstress test usually is performed between 38 and 42 weeks of pregnancy, especially when you’re past your due date, to make sure all’s well with the baby. It can be done as early as the 27th week of pregnancy, if your health care provider feels there are reasons to take a closer look.

For this test, you will sit with knees and back partially elevated, sometimes with a cushion under the right hip to help shift your uterus to the left. Sensitive electrodes (connected to monitors) are placed on your abdomen over conducting jelly. The electrodes can sense the fetal heart rate (FHR) and the presence and length of any uterine contractions. Usually, the results of this test appear on a computer screen, or they are printed out. If there are contractions, the external monitors will show them but they won’t be able to tell how strong they are.

If there is no fetal heart rate increase from being moved around after 30 – 40 minutes, your baby may be napping. Seriously, babies do go to sleep! If that’s the case, you will be given something sweet to drink or a small meal which may perk your baby up and get him moving. If that doesn’t work, the use of fetal acoustic stimulation (sending loud noise to the baby) may work as may gently placing your hands on your abdomen and moving the baby from side to side. Wake up little one!

If your baby still is not as responsive as your health care provider would like to see, you may move on to either a biophyiscal profile (taking a closer look with detailed ultrasound), a stress test (testing to see how your baby responds to contractions) or even delivery.

Alcohol during pregnancy and FASDs

Friday, September 7th, 2012

pregnant-bellySeptember 9 is International Fetal Alcohol Spectrum Disorders (FASDs) Awareness Day. Drinking alcohol during pregnancy can cause FASDs, which include a wide range of physical and mental disabilities and lasting emotional and behavioral problems in a child.

When you drink alcohol during pregnancy, so does your baby. The same amount of alcohol that is in your blood is also in your baby’s blood. The alcohol in your blood quickly passes through the placenta and to your baby through the umbilical cord.

Although your body is able to manage alcohol in your blood, your baby’s little body isn’t. Your liver works hard to break down the alcohol in your blood. But your baby’s liver is too small to do the same and alcohol can hurt your baby’s development. That’s why alcohol is much more harmful to your baby than to you during pregnancy. No amount of alcohol (one glass of wine, a beer…) is proven safe to drink during pregnancy.

Alcohol can lead your baby to have serious health conditions, FASDs. The most serious of these is fetal alcohol syndrome (FAS). Fetal alcohol syndrome can seriously harm your baby’s development, both mentally and physically.  Alcohol can also cause your baby to:
• Have birth defects (heart, brain and other organs)
• Vision or hearing problems
• Be born too soon (preterm)
• Be born at low birthweight
• Have learning disabilities (including intellectual disabilities)
• Have sleeping and sucking problems
• Have speech and language delays
• Have behavioral problems

In order to continue raising awareness about alcohol use during pregnancy and FASDs, the CDC has posted a feature telling one woman’s story and her challenges with her son who has FASD. It’s an eye opener. The CDC’s FASD website has lots more information, too.

What is a nuchal cord or loop?

Monday, July 30th, 2012

Sometimes the umbilical cord may become wrapped around a part of a developing baby’s body. This is most often found around the baby’s neck and happens when the baby moves through a loop of the cord. Less frequently, the umbilical cord becomes wrapped around other body parts, such as a foot or hand. Generally, this doesn’t harm babies and they are born healthy.

Believe it or not, this happens more often than you might think. One loop around the neck occurs in approximately 20% of pregnancies, while multiple loops occur in 5% of cases. Again, most of the time, everything is fine.

Sometimes, though, fetal monitoring shows heart rate abnormalities during labor and delivery in babies with a nuchal cord. This may be as a result of pressure on the cord.  Doppler ultrasound usually can detect any nuchal loops. Even then, the pressure is rarely serious enough to cause death or any lasting problems. A nuchal loop alone is not a reason to change a woman’s birth plan. Occasionally, a cesarean delivery may be needed if multiple loops are involved or the baby’s heart rate appears to be seriously effected.

How your baby grows – month 9

Monday, October 24th, 2011

pregnant-bellyYour baby:

By the end of the ninth month, your baby is about 19 to 21 inches long and weighs 6 to 9 pounds. Your baby’s lungs are ready to work on their own. Your baby gains about ½ a pound a week. Your baby is still moving and kicking. He moves to a head-down position and rests lower in your belly.

Your body:

Your belly button may stick out. Your breathing should be easier once the baby moves down. But you may need to go to the bathroom more often because the baby is pressing on your bladder. You should feel your baby kicking and moving right up until you give birth. (Tell your provider if you notice any change in how often your baby moves.) You may be uncomfortable because of the pressure and weight of the baby, so rest often. Your feet and ankles may swell. (Put your feet up and try to stay in a cool place.) Your cervix opens up (dilates) and thins out (effaces) as it prepares for birth. You may not gain any weight this month, or you may even lose a pound or two.

How your baby grows – month 8

Monday, October 17th, 2011

bellyYour baby:

By the end of the eighth month, your baby is about 18 to 19 inches long and weighs about 4 to 5 pounds. He can kick strongly and roll around. You may see the shape of his elbow or heel against your belly. (Tell your provider if you notice any change in how often your baby moves.) Your baby’s fingernails have grown to the tips of his fingers. Your baby’s brain and lungs are still growing.

Your body:

You may feel stronger contractions this month. Colostrum may leak from your breasts. This is the fluid that comes out of your breasts before your breastmilk comes in. (Wear breast pads in your bra to help with leaking.) You may have trouble breathing as the baby pushes on your lungs. (Slow down and try to sit and stand up straight.) Your baby may crowd your stomach. (Try eating 4 or 5 smaller meals during the day.) You gain about one pound a week this month.

How your baby grows – month 7

Wednesday, October 12th, 2011

big-bellyYour baby:

By the end of the seventh  month, your baby is about 15 to 16 inches long and weighs about 2 ½ to 3 pounds. Your baby can open or close her eyes and suck her thumb. She kicks and stretches. Your baby responds to light and sound.

Your body:

You should feel your baby move. As he gets bigger, it may feel like he’s rolling around. (Tell your provider if you notice any change in how often your baby moves.) Your ankles and feet may swell. Try lying down and putting your feet up. (If your hands and face swell suddenly, call your provider.) You may get stretch marks on your belly or breasts as they get bigger. You may have “practice contractions.”   (This is OK, but call your provider if you have more than five contractions in 1 hour.) As your belly gets bigger, it may be harder to keep your balance. This makes it easier to fall. Be careful! You may have trouble sleeping. (Try sleeping on your left side or with extra pillows.) You also may sweat more than usual.

How your baby grows – month 6

Monday, October 3rd, 2011

pregnancy-chicYour baby:

By the end of the sixth month, your baby is about 12 inches long and weighs about 1 ½ to 2 pounds. Your baby’s skin is red and wrinkled. It’s covered with fine, soft hair. Your baby can kick strongly now – thump, thump! Your baby’s eyes are almost completely formed. Soon they can start to open and close.

Your body:

The skin on your belly may itch – creams may help relieve the irritation. You may see stretch marks – creams don’t really help with these unless they itch. Your back may hurt – avoid standing for long periods of time and don’t lift heavy things. You may feel pain down the sides of your belly as your uterus gets bigger. You may have constipation – drink more water and fruit juice. (Eat foods with fiber, likes fruits and veggies and whole grains.) You can still have sex, but stop if you feel pain or cramping.
