  Fetal hemoglobin - Wikipedia, the free encyclopedia
Fetal hemoglobin (also hemoglobin F or HbF) is the main oxygen transport protein in the fetus during the last seven months of development in the womb.
Functionally, fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream.
Notably, the P50 value for fetal hemoglobin (i.e., the partial pressure of oxygen at which the protein is 50% saturated; lower values indicate greater affinity) is roughly 19 mmHg, whereas adult hemoglobin has a value of approximately 26.8 mmHg.

 Fetus - Wikipedia, the free encyclopedia
The circulatory system of a human fetus works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
The extra-hepatic portion of the fetal left umbilical vein becomes the adult ligamentum teres hepatis (the "round ligament of the liver").
Fetal hemoglobin enhances the fetus' ability to draw oxygen from the placenta.

 Fetal Ultrasound
Fetal ultrasound can be done by inserting the transducer into the woman's vagina (transvaginal), by moving the transducer across her abdomen (transabdominal), or by a combination of both ways.
Fetal ultrasound is more accurate at determining fetal age during the first trimester (usually to within 5 days) than it is in the third trimester (usually to within 3 weeks).
Fetal ultrasound may not be able to provide a clear picture of the fetus in a woman who is extremely overweight.

 Electronic Fetal Monitoring - It's Time Has Not Yet Come
The fetal heart rate deviations did contribute significantly to the percent variance accounted for in the regression analyses with neonatal outcomes of Apgar scores at 1 and 5 minutes and serial neonatal neurologic examinations.
Although mean estimates for baseline and nadir of the fetal heart rate and duration of the deceleration were not significantly different from the actual values, individual estimates of the three parameters were widely distributed.
The perinatal death rate related to fetal hypoxia was significantly less in the EFM group (zero of 746 versus six of 682; P =.03).

 Fetal Alcohol Syndrome (FAS) - Adoption Encyclopedia
Children with fetal alcohol syndrome are often premature and underweight with small heads and are likely to remain unusually small and thin.
The study concluded that fetal alcohol exposure was a risk factor for adult use of nicotine, alcohol and drug dependence.
Dorris believed the rate of fetal alcohol syndrome was a serious problem among some tribes and was also an often unrecognized problem among all races in the United States.

 Dr. Koop - Fetal Alcohol Syndrome- Health Encyclopedia and Reference
In 1973, Jones and Smith coined the term "fetal alcohol syndrome" (FAS) to describe a pattern of abnormalities observed in children born to mothers who drink alcohol.
Evidence suggests that the morphologic and functional deficits observed in children with fetal alcohol syndrome are related to two concepts - the timing of the toxic event ("critical period") and the peak alcohol concentrations ("critical dosage").
All mothers who drink alcohol are at risk of causing fetal alcohol syndrome in their unborn child.

 Introduction - Fetal Tumors
Fetal tumors are rare, but are associated with serious illness or even death in the fetal or neonatal period.
For example, fetal goiter may cause obstruction of labor due to the size of the tumor and associated hyperextension of the fetal neck.
Fetal and/or maternal exposure to exogenous factors, including ionizing irradiation, drugs and viruses, may start the biological mechanisms responsible for tumor formation (1).

The techniques of antepartum fetal surveillance, which are based on the assessment of fetal heart rate patterns, have been in clinical use for nearly 30 years.
The contraction stress test is interpreted by the presence or absence of late fetal heart rate decelerations, which are defined as decelerations that reach their nadir after the peak of the contraction and that usually persist beyond the end of the contraction.
Fetal heart rate decelerations that occur in the presence of contractions that are more frequent than every two minutes or last longer than 90 seconds.

 Fetal Alcohol Syndrome
Fetal alcohol syndrome (FAS) is a serious health problem that tragically affects its victims and their families, but that is completely preventable.
Victims of fetal alcohol syndrome often experience mental health problems, disrupted school experience, inappropriate sexual behavior, trouble with the law, alcohol and drug problems, difficulty caring for themselves and their children, and homelessness.
Not a single case of fetal alcohol syndrome occurred and no adverse effects on children were found when consumption was under 8.5 drinks per week.

 Fetal Psychology
Fifer has found that fetal heart rate slows when the mother is speaking, suggesting that the fetus not only hears and recognizes the sound, but is calmed by it.
The fetus is likely responding to the cadence of voices and stories, not their actual words, observes Fifer, but the conclusion is the same: the fetus can listen, learn, and remember at some level, and, as with most babies and children, it likes the comfort and reassurance of the familiar.
In the first formal study of fetal temperament in 1996, DiPietro and her colleagues recorded the heart rate and movements of 31 fetuses six times before birth and compared them to readings taken twice after birth.

 OBGYN.net - Auditory Evoked Response Test to Evaluate Fetal Health
A adequate method for measuring fetal response to auditory stimulation and correlating it with present or absent fetal risk factors was developed and the matured score ratings was able to separate normal response (scores 6 to 10) from abnormal responses (scores 0 to 5).
This was obtained and in these papers he was able to detect early fetal distress, to discriminate, by the type of obtained response to sound stimulation early in labor, which the fetus was to be born vigorous or with low Apgar scores.
Other major observations were also made, as the progressive decrease of fetal response to sound stimulation during labor and the protective effect of the membranes upon the intensity of fetal responses.

 Fetal heart monitoring - UMMC
Normal values indicate that the fetus is not in distress by showing a fetal heart rate between 120 to 160 beats per minute, with variability of 5 to 25 beats per minute from the baseline or normal fetal heart rate.
It is not uncommon for the fetal heart rate to drop slightly during a contraction, since placental blood supply is diminished under the compression of a uterine contraction, as long as the FHR recovers quickly once the contraction has stopped.

 New Device Approval
Oxifirst™ should be used along with conventional electronic fetal monitoring when the fetal heart rate is "non-reassuring," that is, when it indicates that the baby may be in distress due to lack of adequate oxygen.
It is hoped that the understanding of fetal condition during labor will improve as a result of the additional information that comes from measuring fetal oxygen levels with this new monitor.
This indicates that clinical understanding of fetal condition during labor improved with the use of this new monitor.

 AllRefer.com - fetal alcohol syndrome (Pathology) - Encyclopedia
fetal alcohol syndrome (FAS), pattern of physical, developmental, and psychological abnormalities seen in babies born to mothers who consumed alcohol during pregnancy.
The abnormalities include low birthweight, facial deformities, and mental retardation, and there appears to be an association with impulsive behavior, anxiousness, and an inability on the part of the affected children to understand the consequences of their actions.
When some but not all of these abnormalities are present, they are referred to as fetal alcohol effects (FAE).
