Q

Despite adequate resuscitation (intubated, chest compressions), a newborn still has HR < 60 bpm. What is the next thing to do?

a. Check ET
b. Give epinephrine IV or Intrathecal

A

B. give epinephrine

NTP: Pediatric advanced life support bradycardia algorithm

heart rate less than 60 beats/min with poor perfusion is an indication to begin chest compressions. If despite adequate oxygenation and ventilation, bradycardia persists, give epinephrine

providers should assess and treat factors known to cause bradycardia, referred to collectively as the 6 Hs (hypoxia, hypovolemia, hydrogen ions [acidosis], hypokalemia or hyperkalemia, hypoglycemia, hypothermia), and 4 Ts (toxins, tamponade, tension pneumothorax, and trauma [causing hypovolemia, intracranial hypertension, cardiac compromise or tamponade])

Q

Which reason will make repair of neonatal tongue-tie valid?

a. Interference with feeding
b. possible interference with speech

A

a. interference with feeding
b. possible interference with speech - for an older child, this may be the answer, but for neonatal tongue-tie, interference with feeding makes repair justified

CH 307 Common lesions of the Oral Cavity
“Ankyloglossia or “tongue-tie” is characterized by an abnormally short lingual frenum that may hinder the tongue movement but rarely interferes with feeding or speech. The frenum may spontaneously lengthen as the child gets older. If the extent of the ankyloglossia is severe, speech may be affected and surgical correction indicated”

CH 88.2 Care of the Newborn
“ankyloglossia is rarely a reason for cutting it. If there are problems with feedings (breast or bottle) and the frenulum is short, frenulotomy may be indicated.”

Q

Newborn with HIE (mahaba ang case description, di ko na maalala), what is the most important diagnostic approach?

a. MRI
b. CT scan
c. EEG
d. MRI + EEG

A

a. MRI

*Nelson’s:
UTZ – limited utility in HIE in the term infant, preferred in preterms
CT - limited ability to identify cortical injury during the 1st few days of life
MRI – preferred imaging modality because of increased Sn and Sp early in the disease and its ability to outline topography of the lesion.
aEEG – (amplitude integrated EEG) promising modality to determine which infants are at highest risk for significant brain injury, good reliability, a positive predictive value of 85%, and a negative predictive value of 91-96% for infants who will have adverse neurodevelopmental outcome. Helpful in prognostication, not diagnosis.

Q

Mother was diagnosed with chorioamnionitis on delivery of her baby. Baby had an APGAR of 8,8, term, but was noted to be tachypneic with RR > 60. What is your approach to management?

a. CBC, CXR
b. CBC, Blood CS x 2, CXR
c. CBC, Blood CS x 2, CXR, start antibiotics
d. CBC, Blood CS x 2, Lumbar tap, CXR, start antibiotics

A

c. CBC, Blood CS x 2, CXR, start antibiotics

NTP 19th:
Diagnostic evaluation (including blood culture) is indicated for asymptomatic infants born to mothers with chorioamnionitis. All symptomatic infants should be treated with antibiotics after blood cultures are obtained. There is controversy over whether an LP is necessary for all term infants with suspected early-onset sepsis. If the blood culture result is positive or if the infant becomes symptomatic, LP should definitely be performed.

Q

A preterm who is purely breastfed has to be given vitamin supplementation because:
a. LBW infants are found to have higher energy needs
b. Volume of Breastmilk ingested will not be able to provide adequate nutrients in the first weeks of life.
c.

A

LBW and preterm infants should be given supplemental vitamins.
Decreased fat absorption with increased fecal fat loss may be associated with decreased absorption of vitamin D, other fat-soluble vitamins, and calcium in premature infants.

Q

For a 5 day old with HIE, who already coded twice, when should you stop aggressive measures? (actually mas mahaba ang description ng case – basta fulfills brain death criteria in 2 separate examinations—)

a. 12 hours apart
b. 24 hours apart
c. 48 hours apart

A

c. 48 hours apart- 1wk to 2 mos

a. 12 hours apart- >1yr old
b. 24 hours apart – 2mos to 1 yr old
c. 48 hours apart- 1wk to 2 mos

Nelson’s 18th: see table 67-1 Age specific criteria for brain death and 67-2 Diagnosis for brain death
The recommended length of this period of observation varies by age.
1 wk to 2 mos - 2 exams, 48h apart
2 mos to 1 yr - 2 exams, 24h apart
>1yr - 2 exams, 12h apart

If the cause of the coma is hypoxic-ischemic brain injury and the first exam is performed shortly after the insult, a period of at least 24 hr is recommended before the second exam.

Q
Risk Factor for NEC: 
A. prematurity 
B. 
C. 
D.
A

A prematurity
Nelson’s 19 th edition:
Many factors may contribute to the development of a necrotic segment of intestine, gas accumulation in the submucosa of the bowel wall (pneumatosis intestinalis), and progression of the necrosis to perforation, peritonitis, sepsis, and death. The distal part of the ileum and the proximal segment of colon are involved most frequently; in fatal cases, gangrene may extend from the stomach to the rectum. Although NEC is a multifactorial disease primarily associated with intestinal immaturity, the concept of ―risk factors‖ for NEC is controversial. The triad of intestinal ischemia (injury), enteral nutrition (metabolic substrate), and bacterial translocation has classically been linked to NEC. The greatest risk factor for NEC is prematurity. The disorder probably results from an interaction between loss of mucosal integrity due to a variety of factors (ischemia, infection, inflammation) and the host’s response to that injury (circulatory, immunologic, inflammatory), leading to necrosis of the affected area. Coagulation necrosis is the characteristic histologic finding in intestinal specimens. Clustering of cases suggests a primary role for an infectious agent. Various bacterial and viral agents, including Escherichia coli, Klebsiella, Clostridium perfringens, Staphylococcus epidermidis, astrovirus, norovirus, and rotavirus, have been recovered from cultures. Nonetheless, in most situations, no pathogen is identified. NEC rarely occurs before the initiation of enteral feeding and is much less common in infants fed human milk. Aggressive enteral feeding may predispose to the development of NEC.

Q
An evanescent, lacy, reticulated red and/or blue cutaneous vascular pattern appears over most of the body surface when baby is exposed to cold 
A. Cutis marmorata
B. Mongolian spots 
C. 
D. Harlequin color change
A

A. NTP19 Ch 639
Diseases of the Neonate
Cutis Marmorata
When a newborn infant is exposed to low environmental temperatures, an evanescent, lacy, reticulated red and/or blue cutaneous vascular pattern appears over most of the body surface. This vascular change represents an accentuated physiologic vasomotor response that disappears with increasing age, although it is sometimes discernible even in older children. Cutis marmorata telangiectatica congenita is clinically similar, but the lesions are more intense, may be segmental, are persistent, and may be associated with loss of dermal tissue, epidermal atrophy, and ulceration.
