Psychological Pregnancy
One in six pregnancies are estimated to be psychological. The last and most significant recent case occurred in the U.S. On opening the uterus and can not find the baby after he tried to induce labor at the hospital found no fetus.
This is an extreme case but not the first time it happens, is a rare psychological disorder but relatively common, common in many mammals (in dogs is very common) and not only in humans. It is estimated that about 22,000 pregnancies are psychological.

Ultrasonography of the third quarter
Observe the growth of the fetus
Measurements. As always, the sonographer begins by walking the sensor on the entire surface of your abdomen. The fetus is already too big for him to see in its entirety, but stopping on the skull, femurs, the doctor is able to take action. These data are essential to ensure the baby continues to grow normally. At this stage of pregnancy, weighing between 1, 4 and 2 kg and measuring about 40 centimeters, all organs are working and will soon be ready to go.
Morphological examination. The sonographer continues his review focusing on organs have developed a disease from ultrasound in the second quarter, including the brain, heart and kidneys. It checks for example that communications are established between the heart and the atria are normal or that the kidneys are working properly.
The fetal well-being. Another important aspect of ultrasound in the third quarter: make sure the baby is moving well, he made hand movements that his animated face and swallows it normally, which means for the specialist as it breathes well. A Doppler examination to verify the quality of exchanges between mother and child and then feeding the fetus via the placenta.
The presentation of the baby. It has already upside down in the lower segment of the uterus? Perfect. Ready for the big trip, it is likely to remain in that position until delivery. A breech deliveries or it appears in transverse position? Do not worry, he can still turn around and another ultrasound at 37 weeks of pregnancy will make sure. If this is not the case, your gynecologist will prescribe a scanner to measure your pool. If it is large enough, you can give birth vaginally. Otherwise, a cesarean will be scheduled.

Causes of prematurity
Currently, prenatal diagnosis detects not only problems but also maternal fetal problems. Control of the welfare check and allow normal fetal abnormalities and even perform intrauterine fetal treatments.
Checks can be made through:
• Ultrasound or ultrasonography is a diagnostic over the image to visualize through sound waves like a baby grows. It also allows measuring the baby in the uterus and assess its size to calculate indirectly gestational age.
• Alpha-fetoprotein: a blood test to detect problems with the brain or spine in the baby.
• Amniocentesis: an analysis of the liquid in which the baby is being developed to detect genetic disorders. Lets also known fetal lung maturity when the study was done in about the 36th week of pregnancy.
Statistics indicate that preterm births have not declined despite advances and regular checks of pregnancy. In Argentina, about 10% of deliveries take place before completion of pregnancy, ie before 37 weeks.
Rest and medication can help prevent contractions and labor before the expected date. When the causes of prematurity are known as incompetent cervix or placental problems. The risk is higher when an infection in the placenta and the fluid bathing the baby. Continuous monitoring is important as bacteriological analysis in order to administer the antibiotic to treat the infection.
The groups at highest risk of preterm labor:
* With a history of:
- One or more abortions or premature deliveries.
- Two or more elective abortions.
- Operations of the cervix.
* During pregnancy:
- Twin pregnancy.
- Increase in amniotic fluid.
- Much stress (physical or psychological).
- Multiple pregnancies.
- Pregnancies that have not previously been viable and current authorized but often end in premature birth by having major pathologies or elderly mother.
