We performed this study to address whether a randomised controlled trial (RCT) of the management of RFM was feasible with regard to: i) maternal recruitment and retention ii) patient acceptability, iii) adherence to protocol. Additionally, we aimed to confirm the prevalence of poor perinatal outcomes defined as: stillbirth, birthweight <10th centile, umbilical arterial pH <7.1 or unexpected admission to the neonatal intensive care unit. ...An RCT of management of RFM is feasible with a low rate of attrition. Investigations decrease maternal anxiety. Participants in the intensive group were more likely to have IOL for RFM. Further work is required to determine the likely level of intervention in the standard care arm in multiple centres, to develop additional placental biomarkers and to confirm that the composite outcome is valid.Trial registration ISRCTN07944306." | ||

Introduction
The fetal period (weeks 9 to 37) is about four times the length of the embryonic period and is a time of extensive growth in size and mass as well as ongoing differentiation of organ systems established in the embryonic period. Clinically this period is generally described as the Second Trimester and Third Trimester. Many of the critical measurements of growth are now carried out by ultrasound and this period ends at birth. The term "Fetal Growth Restriction" (FGR) or intrauterine growth restriction (IUGR) are used to describe when the fetus does not reach full growth potential. This is usually determined by clinical sonography calculations of fetal weight, fetal size, or symmetry.

Second Trimester
- Second Trimester
- Week 12 - CRL 85 mm, femur length 15 mm, biparietal diameter 25 mm.
Begin by working through the features present in the early 10 week female fetus. Then look in detail at the head development in a 12 week fetus.
Then look in detail at the head development in a 12 week fetus showing both forms of ossification in the skull.
Fetal Head Growth
Third Trimester
- Vibration acoustically of maternal abdominal wall induces startle respone in fetus.
- Month 7 - respiratory bronchioles proliferate and end in alveolar ducts and sacs.
- Week 37 to 38 Birth.
- Links: Third Trimester
