Fetal Growth & Fetal well being are different aspects fetal evaluation.
Deficiencies in fetal well being could be associated with fetal growth restriction but it may also be present in fetal macrosomia(diabetes).
Fetal Growth is evaluated by
(I) clinical assessment of uterine size
(II)symphysiofundal height
(III)USS measurements of abdominal circumference
Fetal well being is evaluated by
(I)kick count chart
(II)CTG-non stress test
(III)Amniotic fluid index
(IV)biophysical profile
(V)umbilical artery doppler
Components of biophysical profile are.Each component is given a score of 2.
(I)Fetal movements
(II)Fetal respiratory movements
(III)Fetal tone
(IV)Amniotic Fluid index
(V)CTG-non stress test
Liquor assess chronic hypoxia other 4 parameters assess acute hypoxia
10/10 risk of fetal asphyxia in week 1<1000>2 weeks
3-abnormal venous Doppler
4-abnormal cardiograph/BPP
Whenever I study an interesting topic in Obstetrics and Gynaecology,I use this blog to share the information. I checked the facts as much as I can.l will link to the relevant documents and give the references whenever possible.Please be kind enough to make comments. I hope this blog is also useful for the MRCOG Exam(members of Royal college of Obstetricians & Gynaecologists). My Twitter account is http://www.twitter.com/ravimohanv

Genetics
Chromosomal findings in early miscarriage
40% normal 60% abnormal
Chromosomal abnormalities
1-number
2-structure
Downs syndrome-
1-trisomy 21
2-Robertsonian translocation
3-mosaicism
60% aborted
20%still birth
Robertsonian in Downs 96% denovo
21:21 trans location is 100% recurrence
Maternal age related to all trisomies
Autosomal recessive
Cystic fibrosis 1:2500 babies in U.K
Sex linked recessive
