Caffeine is a respiratory stimulant used to treat and reduce apnea episodes in preterm neonates.

Crepitus and tenderness over the clavicle, along with asymmetric Moro reflex, strongly suggest a clavicle fracture.

Bradycardia >120 bpm is not a clinical concern; severe asphyxia causes heart rates below 100 or 60 bpm.

Follow-up is essential to detect late-onset hyperbilirubinemia after early discharge.

LP helps identify CNS infection, especially if neurological signs are present.

TTN typically improves quickly without need for surfactant; RDS is more severe and persistent.

An Apgar score of 4–6 at 1 and 5 minutes suggests moderate asphyxia.

Sepsis can trigger DIC, leading to low platelet counts.

Intrapartum prophylaxis dramatically reduces neonatal GBS infections.

At 10 minutes, target preductal SpO₂ is 85–95%.

Blood culture is the gold standard for confirming bloodstream infection.

Chest compressions are given for 60 seconds before reassessment.

Turner syndrome (45,XO) presents with features like webbed neck, lymphedema, and widely spaced nipples.

The priority is to open the airway and provide effective ventilation, especially if the baby is apneic or bradycardic.

Cranial ultrasound or MRI can detect brain injury due to hypoxia, such as periventricular leukomalacia.

Prolonged resuscitation beyond 10 minutes is associated with poor neurological outcomes.

Group B Streptococcus is the most common cause of early-onset neonatal sepsis, acquired during delivery.

Serum bilirubin measured in the lab is the most accurate method.

Therapeutic hypothermia is most effective when started within the first 6 hours of life.

Warmth is part of the initial steps for all at-risk infants.

Cooling is typically maintained for 72 hours to maximize neuroprotection.

Cranial ultrasound is the preferred non-invasive tool to detect intraventricular hemorrhage in preterm neonates.

Symmetrical movement of all limbs is a normal finding, suggesting intact motor pathways and healthy tone.

Too much oxygen causes oxidative damage, increasing risk of ROP and chronic lung disease.

Patent ductus arteriosus causes a continuous murmur due to flow from aorta to pulmonary artery.

A blood glucose level of more than 45 mg/dL after 24 hours of life is considered normal for a term neonate.

Placental insufficiency leads to chronic fetal hypoxia, making it a leading cause of birth asphyxia. Acute events like cord prolapse are less common.

Most maternal IgG is transferred in the third trimester, which preterm babies miss — making them more vulnerable to infections.

Secondary apnea occurs after prolonged hypoxia and requires PPV.

Due to anaerobic metabolism, lactic acid accumulates, resulting in metabolic acidosis.

Leukopenia may reflect bone marrow suppression or overwhelming infection.

Human milk reduces NEC, improves immunity, and supports neurodevelopment.

Hip assessments (Barlow/Ortolani maneuvers) are done with the baby supine, hips and knees flexed to evaluate for instability.

Preterm babies lack insulating fat and have immature skin, making them prone to hypothermia.

Feeding improves stool passage and bilirubin clearance.

The “Pulse” component of the Apgar score measures heart rate.

Anti-D prevents maternal sensitization against Rh-positive fetal cells.

Beta-glucuronidase increases bilirubin reabsorption from intestines.

A failed newborn hearing screen should be followed up with repeat testing and referral to audiology to ensure early intervention for hearing loss.

Rh incompatibility arises when an Rh-negative mother carries an Rh-positive fetus.

Delayed umbilical stump separation beyond 3 weeks may suggest leukocyte adhesion defect or other immunodeficiencies.

Gasping is ineffective breathing and warrants PPV, regardless of heart rate.

Post-term neonates often have peeling or cracked skin, meconium staining, and reduced vernix.

PROM (>18 hours) allows ascending bacteria from the genital tract to infect the neonate.

Corticosteroids accelerate surfactant production in fetal lungs and reduce incidence of RDS.

Preterm babies lose heat easily due to their large surface area, limited fat stores, and immature skin.

Conjugated bilirubin is eliminated mainly in stool through bile.

A poor seal prevents air entry into lungs.

A murmur associated with clinical signs like poor feeding warrants urgent evaluation with echocardiography to rule out congenital heart disease.

Post-conceptional (or corrected) age is calculated by adding the age at birth to the number of weeks since birth — used to assess developmental milestones in preterms.

Septic neonates often appear lethargic, poorly perfused, and hypotonic.

Lethargy and poor feeding are early neurological signs of HIE due to brain hypoxia.
