Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
\- AC/EFW \< 3rd centile Or at least two out of three of:
1. AC/EFW \< 10th centile
2. AC/EFW crossing centiles \>2 quartiles
3. Cerebroplacental ratio (CPR) \<5th centile or Umbilical artery Pusitility Index(UAPI )\>95th centile FGR fetuses will not necessarily be SGA at delivery and vice versa. In fact, most SGA are likely to be 'constitutionally' small CPR is the ratio of the Middle cerebral artery Pulsatility Index (MCAPI) to (UAPI). The CPR gradually rises until around the 34th week and subsequently slowly declines until term. Its use has been echoed recently because of association of an abnormal ratio with fetal distress in labor requiring emergency cesarean section , a lower cord pH, admission to the intensive care unit and poor neurological outcomes The biophysical profile (BPP) abnormalities that characterize late FGR include alteration of fetal breathing, oligohydramnios and loss of fetal heart rate reactivity on conventional cardiotocography ( CTG). It seems that BPP becomes abnormal only shortly before stillbirth .

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Pregnant women
Women with uncomplicated singleton pregnancy who are planning a vaginal delivery, gestational age from 36 ± 0/7 weeks until onset of active labor (cervical dilatation ≤ 4cm) and cephalic presentation
Biophsical profile
There are five components measured during the biophysical examination. A score of 2 points is given for each component that meets criteria. The test is continued until all criteria are met or 30 minutes have elapsed. The points are then added for a possible maximum score of 10. A total score of 10 out of 10 or 8 out of 10 with normal fluid is considered normal. A score of 6 is considered equivocal, and a score of 4 or less is abnormal.
Cerebroplacental ratio
CPR is the ratio of the Middle Cerebral Artery Pulsatility Index (MCA PI) to the Umbilical Artery Pulsatility Index (UA PI). The pulsatility indices will be measured from an automated trace of at least three consecutive waveforms of the relevant vessel in the absence of fetal breathing movements or uterine contractions. The angle of insonation will be as close to zero degrees as possible. The UA PI will be recorded from a free-floating section of cord, and the MCA PI will be obtained from the proximal third of the vessel (10, 14).
