Flashcards in Pediactrics Deck (37):
1

cough

brainstem reflex

2

cough receptors

middle ear, sinuses, pericardium, diphragm, phaynx, larynx, trachea, major bronchi

3

phases of cough

inspiration
compression
exhalation

4

chronic cough in ped

cough more than 3-4 weeks**

5

cough after eating

overfeeding - decreased with less food
GERD - if with vomiting
TEF - no vomiting - worse with feeding

6

cough with cyanosis not relieved by O2

requires thorough cardiac evaluation

possible R to L shunt

7

cough with tachypnea and fever

sepsis

8

RSV

infants at higher risk
-preterm, cyanotic heart disease, immunodeficient

9

staccato cough first few months

chlamydia trachomatis pneumonia

10

spells with apnea

pertussis

11

wet cough

bronchiectasis

12

rigid bronchoscopy

to see foreign body AND remov\\e it

flexible - cannot remove

13

sore throat, fever, HA, no cough or rhinorrhea

strep pharyngitis

work up with rapid strep and back up culture if negative

NO COUGH OR RHINORRHEA

PE - exudative pharyngitis, tender anterior cervical lymph nodes, scarlatiniform rash, pastias lines

14

drooling, dysphagia, dysphonia, dyspnea, tripod position

epiglottitis

examine airway under anesthesia***

can compromised airway, don't be stupid

15

barking cough, inspiratory stridor

croup
-paryngotracheitis

cause - parainfluenza, influenza, RSV, adenovirus

steeple sign on neck Xray

16

croup tx

inhaled racemic epinephrine
-reduce stridor within 30 minutes
-most immediate benefit

17

upper resp followed by lower resp infection, increased resp effort - tachypnea, nasal flaring, chest retractions, wheezing, crackles

bronchiolitis

RSV, rhinovirus

18

bronchiolitis admit to hospital?

if hypoxic - O2 sat < 90%
-or dehydrated

19

HA, malaise, low grade fever, adolescent, mildly productive cough, wheezing and dyspnea, scattered rales and wheezes

mycoplasma pneumonia

20

premature baby

respiratory distress syndrome

hyaline membane disease

21

CXR for respiratory distress

hyperinflation
air bronchograms
diffuse granularity

can look like group B strep as well
-so give antibiotics

22

prematurity

decreased surfactant
hypoxemia and CO2 retention
acidosis, hypoperfusion
endo and epithelial damage

fibrin > hyaline membrane formation

23

tx CMV

gangciclovir

24

CMV

DNA herpesvirus

massive enlargement of affected cells with inclusions in cells

25

most common congenital viral infection

CMV

hearing impairment**, mental retardation, cerebral palsy

26

transmission of CMV

prenatal or natal infection (cervical/vaginal infections

27

breast milk

sheds CMV

also blood transfusion and organ transplants

28

sensorineural hearing loss

in CMV infants

30-65% of asymptomatic patients

29

coombs negative hemolytic anemia

not immune mediated

30

intracranial calcificaitons

CMV

31

bronchopulmonary dysplasia

premature infants with following RDS

-developed CXR with coarse, streaky infiltration with small ares of emphysema and occasionally appeared cystic

babies on ventilators - O2 is strong oxidizer - high pressure on lungs also damages

32

baby on ventilator

bronchopulmonary dysplasia

33

stage 1 BPD

2-3 days after birth CXR granular appearances

34

stage 2 BPD

4-10 days after birth X-ray shows complete opacification of lungs

35

stage 3 BPD

10-20 days after birth X-ray shows round cystic lucencies with alternating opacities

36

stage 4 BPD

1 month after birth CXR shows enlargement of lucencies and increasing strands of opacity

bubbly lung

37

stress and cytokine

increase surfactant production
