Intrauterine growth restriction (IUGR) occurs in babies with birth weights below the 10th percentile for their gestational age, affecting approximately 3-10% of births in developed countries. Causes include maternal health issues, fetal conditions, and placental deficiencies, with management focusing on monitoring and preparing for delivery of at-risk infants. Diagnosis involves assessing maternal history and fetal growth metrics, while care may include antenatal and postnatal interventions to address potential complications such as hypoxia and nutritional deficits.

2. Intrauterine growth restriction is said to be prsesent in those
babies whose birth weight is below the tength percentile of
the average for gestational age.

3. • Dysmaturity comprised about one third of low birth weight
babies.
• In developed countries , its overall incidence is about
• 3-10%
• Term babies (5%)
• Post term babies (15%)

4. The causes of IUGR can be grouped as
• Maternal causes
• Fetal causes
• Placental causes
• Uterine and Environmental causes.

5. • Pregnancy weight of mother influences the fetal size
• Chronic maternal disease condition
• Renal disease condition
• Malnutrition
• Multiple pregnancy
• Hypertensive disorders of pregnancy
• Severe anemia
• Previous baby suffered iugr etc.

6. • Chromosomal anomalies
• Exposure to an infection
German measles (rubella), cytomegalovirus, herpes
simplex, tuberculosis, syphilis, or toxoplasmosis, TB,
Malaria, Parvo virus
• Birth defects
(cardiovascular, renal, anencephally, limb defect, etc).
• Placenta or umbilical cord defects.

7. • Uteroplacental Insufficiency
• Fetoplacetal Insufficiency
• Abruptio placenta
• Placenta previa
• Post term pregnancy

8. • Septate uterus
• Fibroid/ myoma uterus

9. • High altitude - lower environmental oxygen saturation
• Toxins

10. Due to maternal and placental causes
Decrease in placental transfer of nutrients and oxygen to the fetus
Resulting in reduced fetal body store of lipids, glycogen
Causes neonatal hypoglycemia
Lack of oxygen

11. Chronic hypoxia that leads to erythropoietin production
Polycythemia etc

12. • Based On Pathological Processes
I)Type I- Symmetrical
II)Type II- Asymmetrical

13. • Symmetric IUGR: (33 % of IUGR Infants)
• height, weight, head circumference proportional
early pregnancy insult:
• commonly due to congenital infection, genetic disorder,
or intrinsic factors
• reduced no of cells in fetus
• normal ponderal index
• low risk of perinatal asphyxia
• low risk of hypoglycemia

14. • later in pregnancy:
• commonly due to utero placental insufficiency, maternal
malnutrition, hypoxia, or extrinsic factors
• low ponderal index
• cell number remains same but size is small
• increased risk of asphyxia
• increased risk of hypoglycemia

15. • Weight deficit
• Large head circumference
• Old man look
• Cartilaginous ridges on pinna
• Dry wrinkled skin
• Length remain unaffected
• Open eyes
• Well defined creases
• Alert and active

16. • Normal reflexes Normal cry
• Thin umbilical
• Scaphoid abdomen
• Signs of recent wasting
- soft tissue wasting - diminished skin fold thickness -
decrease breast tissue - reduced thigh circumference
• Signs of long term growth failure
- Widened skull sutures, large fontanelles -
-shortened crown – heel length - delayed development of
epiphyses

17. Diagnosis of IUGR is made by assessing the following
Maternal history may have history of
• chronic hypertension
• severe eclampsia
• chronic renal disease
• diabetes mellitus
• multiple gestation or prior delivery of IUGR

18. -Less Than The Period Of Gestation
-Doesn’t Correspond With The Period Of Gestation .
It Is Less Than Normal
-Fluid Volume Is Diminished

19. -Reveals The Presence Of Congenital Anomalies,
Dereased Amniotic Fluid Volume, And Laeger Ratio Of
Head - To - Abdominal

20. The aims of management of a pregnant women with IUGR
are as follows:-
• Identification of pregnant women at high risk of iugr
• Identification of fetuses wh are malnourished or
SGA(small for gestational age)
• Fetal surveillance for those pregnancied with IUGR

21. Management of IUGR can be described as :-
• Antepartum management
• Intrapartum management
• Immediate management

22. Monitor the mother carefully for fetal kicks counts, fetal
biophysical profile, NST(non stress test) and Doppler
velocimetry.
- mother can be prepared for spontaneous vaginal delivery.
- NST can be repeated twice a daily.

23. - before 48 hours prior to delivery, steroids are administered
to the mother to improve fetal lung maturity.

24. - depend upon cervical dilatation.
ARM (artificial rupture of membrane) is
done , followed by oxytocin as advised.
cervical ripening agents to be used
as per institutional policy.
If there is Fetal distress, Malpresentation, Induction failure and
history of Cesarean section

25. Delivery must be well equipped for delivering IUGR
babies.
An obstetrician and neonatologist should be
available during delivery
• intrapartum monitoring for hypoxia is to be done.
• fetal blood sampling is to be taken for further
action

26. • Infant should be transferred to the NICU for further
care.
• Babies admitted for care at NICU.

27. fetal distress and intrauterine
fetal death may occur
hypoxia and acidosis are common.
:- Immediately after birth, respirtory
distress syndrome, asphyxia, hypoglycemia,
meconium aspiration syndrome and infection etc.
can occur.
