Infant Classification by gestational (postmenstrual) age

  • Preterm < 37wks
  • Term 37 to 41 wks

Intrauterine Growth Retardation

  • Also referred to as SGA

Symmetric IUGR

  • All three parameters are equally affected
  • Early in onset
  • Disease affecting fetal cell no.

– Chromosomal – Genetic – Teratogenic – Infections – hypertension

slide-13
SLIDE 13

Asymmetric IUGR

  • Normal head circumference
  • Late onset
  • Poor maternal nutrition
  • Late onset or exacerbation of maternal

vascular disease

slide-14
SLIDE 14

Etiology

  • Low socioeconomic status
  • Maternal under nutrition
  • Anemia
  • Inadequate prenatal care
  • Drugs misuse
  • Obstetric complication
  • Bad obstetric history
  • Maternal activity

Problems of Prematurity

  • Respiratory
  • Perinatal depression
  • RDS
  • Apnea
  • Chronic lung disease
slide-25

  • Perinatal depression
  • Intracranial hemorrhage
  • Periventricular leukomalacia

Neurological Problems including

slide-26
SLIDE 26

Cardiovascular

  • Hypotension
  • hypovolemia
  • Cardiovascular dysfunction
  • vasodilatation
  • Patent ductus arteriosus
slide-27
SLIDE 27
  • Hematologic
  • Anemia
  • Hyperbilirubinemia
  • Nutritional
  • Gastrointestional
  • Factor for necrotizing enterocolitis
slide-28
SLIDE 28
  • Patent ductus arteriosus
  • Adequate oxygenation
  • Fluid restriction
  • Possible intermittent diuresis
  • Fluid and electrolyte therapy
  • Nutrition
  • Hyperbilirubinemia
  • Phototherapy
  • Exchange transfusion
slide-29

  • Metabolic
  • Renal
  • Temperature regulation
  • Immunologic
  • Ophthalmologic
slide-30

Management of the premature infant

  • Delivery
  • Appropriately equipped and staffed hospital
  • Resuscitation and stabilization
  • Anticipation and prevention
  • Clear airway
  • Initiate breathing
  • Adequate oxygen delivery
  • Maintenance of proper temperature
  • Care of umbilical cord
slide-31
SLIDE 31

Thermal regulation

  • Environmental temperature at which
  • xygen consumption is minimal yet

sufficient to maintain body temperature

  • Maintain temp 36.5-37 oC
  • Humidity 40-60%

–overhead radiant warmer, closed incubator

slide-32
SLIDE 32

Oxygen therapy and assisted ventilation

  • Ways of administration

– Head hood – Nasal prong – Continuous positive airway pressure

  • Risk of injury

– Eyes – lung

slide-33
SLIDE 33

Fluid Requirment

  • Term

– 60-70ml/kg – 100-120ml/kg

  • Preterm

– 70-80ml/kg – 150ml/kg

slide-34
SLIDE 34
  • Daily weight
  • Urine
  • Serum urea nitrogen
  • Serum sodium level
slide-35
SLIDE 35

Total Parenteral Nutrition

  • Life saving for VLBW
  • CVP, peripheral vein
  • Aminoacid2.5-3 gm/kg/d
  • Glucose 10-15gm/kg/d
  • Intralipid 2-3gm/kg/d
slide-36
SLIDE 36

Feeding

  • Method of feeding
  • Avoid fatigue & aspiration
  • Keep NPO

– Respiratory distress – Hypoxia – Circulatory insufficiency – CNS depression – Severe immaturity

slide-37
SLIDE 37

Nasogastric feeding

  • <1.5 kg

– 10ml/kg/d – 20-30ml/kg/d

  • >1.5 kg

– 20-25ml/kg/d

slide-38
SLIDE 38

Oral feeding

  • 34 wks….>2kg
  • Synchronized process of sucking

– Stong sucking effort – Coordination of swallowing

  • Trophic feeding
slide-39
SLIDE 39
  • Iron
  • Folic acid
  • Vitamin A, D, E, K
  • Calcium
slide-40
SLIDE 40
  • Hand washing
  • Avoid over crowding
  • Skin care
  • Early enteral feeding
  • Broad spectrum

– Nosocomial infection

Infection

slide-41
SLIDE 41

Immunization

  • As in term
  • Pertussis vaccine is contraindicated in

infants with possible or documented evolving neurological problem

  • Preterm infants with chronic respiratory

distress should receive influenza immunization at 6 months of if they are not hospitalized

slide-42
SLIDE 42

Long Term Problems of Prematurity

  • Developmental disability
  • Major handicaps
  • Sensory impairments
  • Minimal cerebral dysfunction
  • Retinopathy of Prematurity
  • Chronic lung disease
  • Poor growth
  • Increased frequency of congenital anomalies
slide-43
SLIDE 43

Prognosis

  • Developed countries

– 1.5-2 kg 95% survival

  • High risk of morbidity & mortality in IUGR
  • Higher incidence of rehospitalization in

first 2 yr of life

slide-44
SLIDE 44

Discharge criteria

  • Resolution of acute life threatening illness
  • Stable temp regulation
  • Gaining weight on oral feed
  • Free of apnea
  • Mother’s knowledge
