Frequently Asked Questions
❓ What is a normal newborn?
A normal newborn is a baby born between 37–42 weeks of gestation with appropriate weight for gestational age, stable vital signs, good tone, strong cry, and no major congenital anomalies.
❓ What is IUGR (Intrauterine Growth Restriction)?
IUGR is a condition where the fetus fails to achieve its expected growth potential, usually defined as fetal weight below the 10th percentile for gestational age.
❓ What are the types of IUGR?
There are two main types: Symmetrical IUGR (early insult causing proportionate small size) and Asymmetrical IUGR (late placental insufficiency causing head sparing with body wasting).
❓ What is the ponderal index and why is it important?
The ponderal index is calculated as Weight(g) × 100 / Length(cm)^3. It helps differentiate symmetrical and asymmetrical IUGR. A low ponderal index suggests wasting and asymmetrical IUGR.
❓ How is IUGR assessed antenatally?
Antenatal assessment includes fundal height measurement, ultrasound biometry (especially abdominal circumference), amniotic fluid index, Doppler studies of umbilical artery, and biophysical profile monitoring.
❓ How is IUGR assessed postnatally?
Postnatal assessment includes measuring birth weight, length, head circumference, ponderal index, and identifying clinical features such as thin body, reduced fat, and loose skin folds.
❓ What are the complications of IUGR in newborns?
Common complications include hypoglycemia, hypothermia, polycythemia, birth asphyxia, increased infection risk, and poor neurodevelopmental outcomes.
❓ What is the difference between a preterm and term baby?
Preterm babies are born before 37 weeks and have immature organs, thin skin, weak reflexes, and higher risk of complications, while term babies are born between 37–42 weeks with mature systems.
❓ What are common complications of preterm birth?
Complications include respiratory distress syndrome, apnea of prematurity, necrotizing enterocolitis, intraventricular hemorrhage, sepsis, hypoglycemia, and long-term developmental delay.
❓ What is the APGAR score used for?
The APGAR score evaluates newborn condition at 1 and 5 minutes after birth using Appearance, Pulse, Grimace, Activity, and Respiration to assess need for resuscitation.
❓ What is the normal APGAR score range?
A score of 7–10 is normal, 4–6 indicates moderate depression, and 0–3 indicates severe depression requiring urgent resuscitation.
❓ What are normal vital signs in a newborn?
Normal newborn vital signs include heart rate 120–160/min, respiratory rate 30–60/min, temperature 36.5–37.5°C, and oxygen saturation above 90% after 10 minutes.
❓ What is caput succedaneum?
Caput succedaneum is scalp edema caused by pressure during labor. It is present at birth, soft, crosses suture lines, and resolves within 1–2 days.
❓ What is cephalhematoma?
Cephalhematoma is subperiosteal bleeding over the skull bone. It appears hours after birth, does not cross suture lines, and may cause jaundice due to blood breakdown.
❓ What is subgaleal hemorrhage?
Subgaleal hemorrhage is bleeding between the scalp and skull that crosses suture lines and can rapidly expand, leading to massive blood loss, shock, and life-threatening complications.
❓ How can caput succedaneum and cephalhematoma be differentiated?
Caput is soft, present at birth, and crosses sutures, while cephalhematoma is firm, appears later, and is confined to one skull bone without crossing sutures.
❓ Why is subgaleal hemorrhage considered an emergency?
Because it can cause severe blood loss into the scalp space, leading to hypovolemic shock, anemia, and death if not urgently treated.
❓ What are normal findings on newborn physical examination?
Normal findings include pink color, strong cry, flexed posture, good tone, intact reflexes (Moro, suck, grasp), soft fontanelle, and symmetrical chest movement.
❓ What is the brain-sparing effect in IUGR?
In asymmetrical IUGR, blood flow is preferentially directed to the brain, preserving head growth while the rest of the body shows growth restriction.
❓ What is the best monitoring method for severe IUGR fetus?
Serial ultrasound growth monitoring combined with Doppler flow studies and biophysical profile is the best approach for severe IUGR surveillance.
