HYPERBILIRUBINEMIA Risk Factors • TSB in high risk zone • Jaundice observed in the first 24 hr • Blood group incompatibility or with hemolytic disease (G6PD) • Gestational age 35-36wks • Previous sibling received phototherapy • Cephalhematoma or significant bruising • Exclusive breastfeeding • East asian race
HYPERBILIRUBINEMIA Causes Unconjugatedhyperbilirubinemia • Increased production • Decreased conjugation • Competitive blockage of transferase enzyme • Increased enterohepatic recirculation
HYPERBILIRUBINEMIA Causes Conjugated hyperbilirubinemia • Decreased excretion by damaged hepatic parenchymal cells • Diseases of biliary tract
HYPERBILIRUBINEMIA Physiologic Jaundice • Jaundice at 2nd – 3rd day of life • Result of increased bilirubin production from the breakdown of fetal RBC combined with transient limitation in the conjugation due to immature liver • Decreases between 5th - 7th day of life
HYPERBILIRUBINEMIA vs Pathologic Jaundice if: • It appears in the first 24-36 hrs of life • Serum bilirubin is rising at a rate faster than 5mg/dL/24hr • Serum bilirubin is >12mg/dL in FT or 10-14mg/dL in PT • Jaundice persists after 10-14 days of life • Direct reacting bilirubin is >2 mg/dL • With signs of kernicterus
HYPERBILIRUBINEMIA ABO incompatibility • 15% of live births are at risk but manifestations of disease develop in 0.3-2.2% • Mother is type O while baby is A or B • Results from the presence of IgG antibodies against type A or B that can cross the placenta • Dx: ABO incompatibility, positive Coomb’s test
HYPERBILIRUBINEMIA • Low risk >= 38 wks and well Medium risk >= 38wks+risk factors or • High risk 35-37 6/7 + risk factor 35-36 6/7 wks and well
NEONATAL SEPSIS Incidence: 1-4% in preterm, <1% in term infants Risk Factors: • Premature labor • Prolonged rupture of fetal membranesmonoc • Low birth weight • Chorioamnionitis • Maternal fever
NEONATAL SEPSIS Etiology • Gram (+) cocci – Group B beta hemolytic strep, S. aureus, S. epidemidis • Gram (-) cocci- E. coli, Klebsiellapneumoniae • Gram (+) rods – Listeriamonocytogenes
NEONATAL SEPSIS Signs and Symptoms • Unexplained respiratory distress • Unexplained feeding intolerance • Temperature instability • Hypo/hyperglycemia • Apnea • Lethargy • Irritability
NEONATAL SEPSIS Sepsis Work up • CBC • Blood culture • Lumbar puncture • Urinalysis • Chest xray
NEONATAL SEPSIS Treatment • Empiric : penicillin + aminoglycoside, change antibiotic according to the result of culture • Nosocomial: antibiotics should depend on nursery exposure information • Duration: 7-10 days except for invasive infections i.e. osteomyelitis
