The tissue samples are sent to a genetic lab to grow and be tested. Results are often available in 10 days to 2 weeks, depending on the lab. They may need a follow-up amniocentesis.
In some cases an active vaginal infection such as herpes or gonorrhea will prohibit the procedure. Other times the healthcare provider takes a sample that does not have enough tissue to grow in the lab. That may cause incomplete or inconclusive results. During late pregnancy and during labor, your healthcare provider may want to watch the fetal heart rate and other functions.
Fetal heart rate monitoring is a way of checking the rate and rhythm of the fetal heartbeat. The average fetal heart rate is between and beats per minute. It may change as the fetus responds to conditions in the uterus.
An abnormal fetal heart rate or pattern may mean that the fetus is not getting enough oxygen or there are other problems. It also may mean that an emergency or cesarean delivery is needed. The most basic type of fetal heart rate monitor is to use a type of stethoscope called a fetoscope. Another type of monitoring is with a hand-held Doppler device. This is often used during prenatal visits to count the fetal heart rate.
During labor, continuous electronic fetal monitoring is often used. The specific details may vary slightly, but electronic fetal monitoring often follows this process:. The healthcare provider puts gel on your abdomen to help the ultrasound transducer work properly. The provider attaches the ultrasound transducer to the abdomen with straps and sends the fetal heartbeat to a recorder. The fetal heart rate is displayed on a screen and may be printed onto special paper.
During contractions, a monitoring device external tocodynamometer is placed over the top of the uterus with a belt. This device can record the patterns of contractions. Sometimes, internal fetal monitoring is needed for a more accurate reading of the fetal heart rate.
This monitoring can be done when birth is close. Your amniotic sac must be broken and your cervix must be partially dilated to do it.
Internal fetal monitoring involves putting an electrode through the dilated cervix. The electrode is attached to the scalp of the fetus. The first 1-hour test is a glucose challenge test. If the results are abnormal, a glucose tolerance test is done. A glucose tolerance test is often done in weeks 24 to 28 of pregnancy. It measures levels of sugar glucose in your blood.
Abnormal glucose levels may be a sign of gestational diabetes. The provider will draw blood several times over several hours to measure the glucose levels in your body. Group B streptococcus GBS are bacteria found in the lower genital tract of about 1 in 4 women. GBS infection often causes no problems in women before pregnancy. But it can cause serious illness in the mother during pregnancy. GBS may cause chorioamnionitis. This is a severe infection of the placental tissues.
It can also cause postpartum infection. Urinary tract infections caused by GBS can lead to preterm labor and birth, or pyelonephritis and sepsis. They are some of the most commonly used medicines for pain and fever. NSAIDs are used to treat medical conditions such as arthritis, menstrual cramps, headaches, colds, and the flu. Common side effects of NSAIDs include stomach pain, constipation, diarrhea, gas, heartburn, nausea, vomiting, and dizziness. Additional Information for Pregnant Women.
FDA is warning that using pain-relieving and fever-reducing nonsteroidal anti-inflammatory drugs NSAIDs around 20 weeks or later in pregnancy may cause kidney problems in the unborn baby, which can lead to low levels of amniotic fluid that surrounds the baby.
Complications can occur with low levels of this fluid. If you are pregnant, do not use NSAIDs at 20 weeks or later in pregnancy unless specifically advised to do so by your health care professional because these medicines may cause problems in your unborn baby.
Talk to your health care professional or pharmacist if you have questions or concerns about NSAIDs or which medicines contain them. Additional Information for Health Care Professionals. FDA is warning that use of nonsteroidal anti-inflammatory drugs NSAIDs around 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment.
These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation.
Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. If NSAID treatment is deemed necessary between 20 to 30 weeks of pregnancy, limit use to the lowest effective dose and shortest duration possible. As currently described in the NSAID labels, avoid prescribing NSAIDs at 30 weeks and later in pregnancy because of the additional risk of premature closure of the fetal ductus arteriosus.
The above recommendations do not apply to low-dose 81 mg aspirin prescribed for certain conditions in pregnancy. Data Summary. Table 1.

Ask about the benefits and risks for you and your baby. What medicines and herbs should I avoid? Some drugs can harm your baby during different stages of your pregnancy.
At these times, your healthcare provider may have you take something else. Will I need to take more or less of my medicine? Your heart and kidneys work harder when you are pregnant. This makes medicines pass through your body faster than usual. Can I keep taking this medicine when I start breastfeeding? Some drugs can get into your breast milk and affect your baby. What kind of vitamins should I take? Ask about special vitamins for pregnant women called pre-natal vitamins.
Pre-Natal Vitamins Some dietary supplements may have too much or too little of the vitamins that you need. Sign Up for a Pregnancy Registry Pregnancy Exposure Registries are research studies that get information from women who take prescription medicines or get a vaccine during pregnancy.

Studies have further established the teratogenic effect of high-dose fluconazole during the first trimester, and yet have provided considerable reassuring data regarding its use at single and low dose in this key period.
Studies have also provided additional safety data on lipid derivatives of amphotericin B. However, major continuing gaps remain to be filled. We have experienced in the last 10 years a large expansion of the antifungal armamentarium, with the rise of new drugs exhibiting an excellent tolerance profile and efficacy and a new activity spectrum. Despite these advances, amphotericin B deoxycholate, one of the oldest antifugals and for sure the one displaying the worst tolerance profile, remains in the pivotal antifungal drug in pregnant women.
Fetal toxicity indeed remains the major therapeutic concern, above potential maternal toxicity. Alternatives are almost non-existent. Whereas some experts consider the use of fluconazole in very selected situations after the first trimester, the safety of long-term exposure to fluconazole beyond this period has still not been assessed.
Posaconazole and echinocandins have never been evaluated in pregnant women, and should therefore not be used. Because only scant pharmacokinetics and tolerance data are available, careful pharmacovigilance and reporting of any antifungal prescription during pregnancy is mandatory to improve our knowledge on drug safety and efficacy during pregnancy.
Meanwhile, cautious multidisciplinary evaluation of the maternal—fetal risks and benefits should guide a personalized and expert antifungal prescription. All other authors: none to declare.
