    release of meconium, muscle relaxation from hypoxia in utero, goes floppy, muscles in rectum relax, float in amniotic fluid. If hypoxic and gasp in utero, meconium sucked into windpipe and lungs

    • Early feed
    • Monitor CP, temp, sat, BS
    • Obtain hct
  37. What causes RDS in preterm infants
    Unable to produce surfactant in lung to keep alveoli open which leads to collapse of alveoli
  38. Treatment for RDS
    • Administer Surfactant (1 dose in DR) per ETT (not in community hospital) if spontaneous respirations take tube out and see how baby does

  42. What is the increase of NAS babies in TN compared to nation
    15 fold increase compares to 3 in nation
  43. Who is best qualified to obtain history for NAS baby
    social worker
  44. Care of NAS baby (assessment)
    • Obtained bagged urine (1st sample)
    • Obtain meconium (7-10 days to get back)
    • Monitor feeding
    • Observe behavior
    • Draw labs to differientiate NAS and CNS irritability (CBC, BS, Ca, Mg, TSH, T4, CXR)
    • Use NAS scoring system
    • Most use modified Finnegan score
  45. Signs of NAS baby
    • Increased wakefulness
    • High-pitched, shrill cry
    • Tremors, jittery
    • Hyperactive Moro
    • Increased Muscle tone
    • excessive, uncoordinated sucking
