Case

3-week-old boy brought to ED with c/o emesis since first week of life

Formula changed twice with no improvement

Effortless spitting up after each feed

Birthweight 7 lbs 2 oz, now 8 lbs

what s appropriate rate of weight gain for babes
What’s appropriate rateof weight gain for babes?

Regain BW by 10 days

then 20-30 g per day 1st 3 months

Double BW by 5 months of age

15-20 g /day 3-6 months

10-15 g/day 6-9 months

10 g/day 9-12 months

gastroesophageal reflux prevalence
Gastroesophageal refluxPrevalence?

> 40% of infants regurgitate >once/day

  • 50% resolve by 6 months, 75% by 12 months, 95% by 18 months

Nelson et al, Arch Pediatr Adolesc Med, 2000

Orenstein, Pediatr Rev, 1999

gastroesophageal reflux
Gastroesophageal reflux

Not a disease in most cases…

simply reflects immature LES tone

only ~ 1 in 300 infants has “significant” reflux with associated complications

Nelson’s Pediatrics 2000

name 5 complications of infant ge reflux
Name 5 complications of infant GE reflux:

1. Parental anxiety

    • the biggie

2. Esophagitis

(arching, irritability, Sandifer)

  • Failure to thrive
  • Apnea/choking (ALTE)

5. Recurrent aspiration

ge reflux diagnosis
GE reflux: diagnosis

Clinical!!!

Confirmation of more severe reflux:

24 hour pH probe

Milk scan

UGI barium not sens/specific

ge reflux treatment options
GE reflux: treatment options

* Consultation with peds or GI

slide10
Case

Teary, very stressed 23-year-old first time mom with 3-day-old breast-fed little girl

  • ++ worried that baby “not getting enough”
  • seems hungry, spends 40 minutes nursing but is “on and off repeatedly, cries a lot
  • “my breasts are REALLY SORE, and I’m not sure I even have enough milk for her….”
  • “I called HealthLink to see if I could give her formula and the nurse gave me a 10 minute lecture about the importance of breast-feeding.”
baby s exam
Baby’s exam:

No dysmorphism; moderate jaundice

Alert, rouses easily, strong cry

AF normal, roots, v. strong suck, oropharynx/palate normal

Normal RR bilat

Chest clear, CVS normal, good pulses; sl. mottled extremities

Abdomen/umbilicus normal

Normal female genitalia and anus

Spine/hips normal

Normal Moro, grasp, tone, reflexes

ed s rules of infant nutrition
Ed’s rules of infant nutrition

1. “Breast is best”…..

…but ultimately the kid simply needs enough to eat!!!

2. Lactation consultants are your friends

signs of inadequate intake in bf infant neifert clin perinatol 1999
Signs of inadequate intake in BF infantNeifert, Clin Perinatol 1999
  • Irregular or non-sustained sucking at breast
  • < 1 wet diaper per feed
  • Nursing < 10 minutes/breast each feed; also, shouldn’t be > 25 minutes/breast
  • Failure to demand to nurse at least 8 times daily
  • Taking only 1 breast at each feeding
  • Crying, fussing, and appearing hungry after most feedings
  • Too much weight loss in first week, suboptimal gain thereafter
bf strategies
BF strategies
  • Nipple care
    • Exposure to air, keep dry b/w feeds, apply lanolin, manual milk expression, more freq shorter feeds, nipple shields
  • Proper technique
    • Feed when hungry
    • Ensure proper latch – watch babe feed in ED
    • Most babies are not “avid suckers” in the first three days; by day 4 they “wake up” and start packing on the weight they’ve lost
  • Supplemental bottle feeds with manually expressed milk or formula if necessary
    • “nipple confusion” is overblown!!
bf strategies1
BF strategies
  • Before assuming mom has insufficient milk, exclude 3 possibilites:
    • Errors in feeding technique
    • Remediable maternal factors: diet, lack of rest, or emotional distress
    • Physical disturbances in the baby that interfere with eating or weight gain
slide16
Case
  • 4-week-old babe presents with very anxious parents – he’s been crying incessantly for several hours, completely inconsolable; several other episodes over past few days, seems to be getting worse. Otherwise feeding well, 6 wet diapers/day, stooling well, no fever. Previously well.
  • Approach?
how much crying is normal
How much crying is normal?

At 2 weeks: 2 hours per day

Increases to 3 hours at 6 weeks, then declines to ~ 1 hour at 12 weeks

infantile colic
Infantile colic
  • Excessive crying or fussiness
  • Occurs in 10-20% of infants

Defined as paroxysms of crying in an otherwise healthy infant for > 3 hours/day on > 3 days/week, usually begins ~ 3 weeks of age and resolves at around 3 months of age

If things haven’t settled by 4 months, consider alternate dx

colic
Colic
  • Intense crying for several hours, usually in late afternoon or evening
  • Often infant appears to be in pain, may have legs drawn up, may have slight abdominal distension
  • May have temporary relief with passage of gas

Repercussions:

      • early discontinuation of BF
      • Multiple formula changes
      • Parental anxiety and distress
      • Increased incidence of child abuse
colic etiology
Colic: etiology?

Unknown:

? Temperament

? Ineffective parental response to crying

? Overfeeding

? Hunger

colic diff dx
Colic: diff dx?

Rule out:

  • Hair tourniquet
  • Corneal abrasion
  • Incarcerated hernia
  • Consider abuse (shaken baby)
  • Other (ie reflux esophagitis, UTI, inguinal hernia, testicular torsion, intussusception, etc)
hair tourniquet
Hair tourniquet

Treatment?

  • Excision
  • “Nair”
colic management
Reasonably effective:

Counseling/ reassurance

Respite care

Feeding/holding/rocking/sleeping/diaper change

Routine burping, avoid over/underfeeding

F/U with GP or peds to provide support and ensure no organic etiology

Rarely effective:

Formula changes

Simethicone to decrease intestinal gas

Music, car rides, swings etc

? Phenobarb or benadryl for occasional relief

Colic: management
slide24
Case
  • 10 day old female with foul-smelling discharge from umbilicus
  • Afebrile, feeding/voiding/pooping well, no red flags on history

Just a smelly belly button or something more?

omphalitis
Omphalitis

  • S. aureus/Group A Strep/Gm –’s
  • Tx; topical care and systemic antibiotics (
omphalitis complications
Omphalitis: complications
  • Necrotizing fasciitis
  • Sepsis
  • Portal vein thrombosis
  • Hepatic abscesses
when should the umbilical cord separate
When should the umbilical cord separate?
  • Usually w/i 2 weeks
  • Delayed separation: think of possible leukocyte adhesion defect
slide28
Case

3 day old babe:

  • Red eye with discharge
  • Differential diagnosis?

    • Chlamydia
    • Herpes simplex
    • Infantile glaucoma

Diagnosis: gram stain, culture, flourescein, antigen detection

congenital nasolacrimal duct obstruction
Congenital nasolacrimal duct obstruction

5% of all newborns

*absence of conjunctival injection!

Warm compresses, gentle massage, watchful waiting

95% resolve by 6 months; if not, refer for probing (earlier if multiple episodes of dacryocystitis)

dacryocystitis

    • Rx concomitantly for Chlamydia
    • Rx mom and her partner
chlamydial conjunctivitis
Chlamydial conjunctivitis

C. trachomatis : presents on day 3-10

(but may be up to 6 weeks)

Mom with active untreated chlamydia: babe has 40% chance of infection

What’s the real worry here?

  • 10-20% have associated pneumonia – untreated can lead to chronic cough and pulmonary impairment
  • “well” with pneumonia and staccato cough
  • Creps/wheezes; patchy infiltrates w/ hyperinflation
  • CBC: eosinophilia
  • Rx: systemic erythro x 14 days
  • Treat mom and her partner,
herpetic conjunctivitis

Classic triad (seen in 30%):

    • Epiphora
    • Photophobia
    • Blepharospasm
  • Injected red watery eye

  • Exam: Alert, GCS 15, not hoarse; has circumoral 1st and 2nd degree burn; 15% BSA 2nd degree burns to rest of body

Mgt?

fluid management
Fluid management
  • Note that the Parkland formula is modified for kids < 20 kg: accounts for proportionately higher maintenance fluid req in smaller children = 3 mL/kg/% burn (1/2 in 1st 8 hours) PLUS maint fluids
  • Know the rule of thumb for maint fluids in kids: 4-2-1
    • 4 ml/kg 1st 10 kg
    • 2 ml/kg 2nd 10 kg
    • 1 ml/kg >20 kg
example 12 kg kid with 10 bsa burn
Example: 12 kg kid with 10% BSA burn

Conventional Parkland formula:

  • 4 x 12 x 10 = 480 mL
  • ½ in 1st 8 hours = 30 mL/h

Modified formula:

  • 3 x 12 x 10 = 360 mL
  • ½ in 1st 8 hours = 23 mL/h
  • Add maint fluid: 44 mL/h
  • TOTAL fluids = 67 mL/h

when is a bhe not a bhe
When is a BHE not a BHE?
  • Precipitating event is minor or non-existent
  • Hx of no or minimal crying or breath-holding
  • Episode last > 1 minute
  • Period of post-episode sleepiness lasts > 10 minutes
  • Convulsive component of episode is prominent and occurs before cyanosis
