Study Notes
Meconium Aspiration Syndrome (MAS)
- Meconium aspiration occurs when the baby's first feces is ingested during labor due to intestinal contractions and anal sphincter relaxation, contaminating amniotic fluid (AF).
- Aspiration can happen hours before, during, or immediately after delivery, depriving the baby's brain of oxygen and potentially causing brain damage.
- Causes include fetal distress during labor, maternal hypertension, oligohydramnios, maternal infection, maternal drug use, and placental insufficiency.
- Symptoms include rapid breathing, retractions, grunting sounds, cyanosis, and an overdistended chest.
- Prevention involves amnioinfusion, which thins out thick meconium in AF by pumping sterile fluid into the AF.
Neonatal Sepsis
- Neonatal sepsis is a blood stream infection (BSI) that occurs in the first month of life, often caused by E. coli, GBS, and HSV.
- It is the leading cause of neonatal death in hospitals and communities.
- There are two categories: Early-Onset Sepsis (EOS), which presents within 72 hours of life, and Late-Onset Sepsis (LOS), which occurs after 72 hours.
- Symptoms include body temperature changes, breathing problems, diarrhea, vomiting, low blood sugar, reduced movements, and seizures.
- Diagnosis involves CSF, blood, and urine cultures, as well as lumbar puncture.
- Treatment includes antibiotics and diet modifications, such as NPO, parenteral nutrition, and NGT feeding.
- Prevention involves giving antibiotics to mothers infected with GBS during labor and delivery.
Hyperbilirubinemia
- Hyperbilirubinemia is a condition where there is too much bilirubin in the blood, which can cause seizures and brain damage if left untreated.
- Causes include physiologic jaundice, breastmilk jaundice, breastfeeding failure jaundice, jaundice from hemolysis, and inadequate liver function.
- Symptoms include yellow skin and eyes, poor feeding, and lethargy.
- Diagnosis involves measuring direct and indirect bilirubin levels, RBC count, and blood type incompatibility.
- Treatment options include phototherapy, fiberoptic blanket therapy, exchange transfusions, and adequate hydration.
