International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not. How can we interefere in something we do not understand? Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart. One notable exception is Gray’s Anatomy. Gray’s Anatomy describes inflation of the neonatal lungs as the first change after birth and does not describe any changes in the afterload of the heart.

Ultrasonography of the cervix[ edit ] Fetus at 14 weeks profile Obstetric sonography has become useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is undesirable: This includes checking the status of the limbs and vital organs, as well as sometimes specific tests for abnormalities. Some abnormalities detected by ultrasound can be addressed by medical treatment in utero or by perinatal care, though indications of other abnormalities can lead to a decision regarding abortion.
Perhaps the most common such test uses a measurement of the nuchal translucency thickness “NT-test”, or ” Nuchal Scan “. Ultrasound may also detect fetal organ anomaly. Usually scans for this type of detection are done around 18 to 23 weeks of gestational age called the ” anatomy scan “, “anomaly scan,” or “level 2 ultrasound”. Some resources indicate that there are clear reasons for this and that such scans are also clearly beneficial because ultrasound enables clear clinical advantages for assessing the developing fetus in terms of morphology, bone shape, skeletal features, fetal heart function, volume evaluation, fetal lung maturity,  and general fetus well being.
Soft markers are variations from normal anatomy, which are more common in aneuploid fetuses compared to euploid ones. These markers are often not clinically significant and do not cause adverse pregnancy outcomes. Randomized controlled trials have followed children up to ages 8—9, with no significant differences in vision, hearing, school performance, dyslexia, or speech and neurologic development by exposure to ultrasound.

Prior to the 18th century, caring for pregnant women in Europe was confined exclusively to women, and rigorously excluded men. The expectant mother would invite close female friends and family members to her home to keep her company. The presence of physicians and surgeons was very rare and only occurred once a serious complication had taken place and the midwife had exhausted all measures to manage the complication.
Calling a surgeon was very much a last resort and having men deliver women in this era whatsoever was seen as offending female modesty. However, the subject matter and interest in the female reproductive system and sexual practice can be traced back to Ancient Egypt  and Ancient Greece. Living in the late first century A. After the death of Soranus, techniques and works of gynecology declined but very little of his works were recorded and survived to the late 18th century when gynaecology and obstetrics reemerged.
These advances in knowledge were mainly regarding the physiology of pregnancy and labour. By the end of the century, medical professionals began to understand the anatomy of the uterus and the physiological changes that take place during labour. The introduction of forceps in childbirth also took place during the 18th century. All these medical advances in obstetrics were a lever for the introduction of men into an arena previously managed and run by women—midwifery.
In the 18th century medical men began to train in area of childbirth and believed with their advanced knowledge in anatomy that childbirth could be improved. In France these male-midwives were referred to as “accoucheurs”.
HCG Levels for normal Pregnancy. The quantitative maternal serum beta HCG peaks at approximately 10 weeks and then reduces. It will be difficult to see if the mother has a retroverted uterus or fibroids. The GS is an echogenic ring surrounding an anechoic centre.

Please ask your midwife on admission regarding room availability.

Triploidy Other defects with normal karyotype[ edit ] In fetuses with a normal number of chromosomes, a thicker nuchal translucency is associated with other fetal defects and genetic syndromes. The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness.
It is important to distinguish the nuchal lucency from the underlying amniotic membrane. Among those fetuses whose nuchal translucency exceeds the normal values, there is a relatively high risk of significant abnormality. Further, other, non-trisomic abnormalities may also demonstrate an enlarged nuchal transparency. This leaves the measurement of nuchal transparency as a potentially useful first trimester screening tool.
A Nuchal Translucency Scan (NTS) is a screening test to check for Trisomy 21 (Down syndrome), Trisomy 18 (Edwards’s Syndrome), Trisomy 13 (Palau’s Syndrome).
