Flashcards in Lung Devo Deck (28):
1

presentation resp distress

tachypnea, tachycardia

flaring nostrils 

chest retraction

expiratory grunt

cyanosis

anxious express

2

preop management TEF and esophogeal aphasia

patient at 30derees

repogle in proximal pouch to handle secretions

Search for comorbidities

identify position of aortic arch

2

risk of post-natal steroids in RDS

cerebral palsy

3

embryonic speculation in CCAM

asynchronous maturation of developing lung bud and surrounding mesenchyme 16-20wks results in overgrowth of terminal air strucutres

3

at __wks, fetal luungs may be able to support life (with assistance)

24-27wks

4

congential cystenic adenoamatoid malformation likely a ___ anaomaly

bronchiole

6

most common repiratory/esophogeal abnormality

esophogeal atresia with distal esophogeal fistula (to trachea)

6

cray findings RDS

low lung volume

diffuse atelectasia (ground glass)

air bronchograms

pneumonia-like (but not isolated region)

7

infants with resp distress often develop ___ in lungs

hyalien membrane

7

lab findings RDS

moderate hypoxia

resp acidosis

metabolic acidosis

8

most common cause of resp distress in preterm infants

RDS

9

presentation esophogeal atresia with distal trachea-esophogeal fistula

air in bowel on X-ray

bronchoscopy indentifies fistula

9

pathogenesis hyaline membrane formation in respiratory distress

Type I cell injury >

breakdown of air/capillary barrier > 

serum leak into alveolar lumen > 

hyaline forms + surfactant disrupted

10

Lab tests to evaluate risk for RDS

lecithin/spingomyelin ration

presence of phosphatidylglycerol (more accurate)

12

presentation CCAM

single lobe

air trapping > distention

resp distress (rare)

recurrent pulmary infxn

prenatal ultrasound

14

delayed repair candidates for EA with distal TEF

significant pul compromise

sig cardiac anomalies

long gap atresia,

 

15

= primative alveoli

terminal sacs

16

histological pattern CCAM

adenomatoid

alveolar psaces lined by repsiratory and mucus secreting epithelium =glandular

17

risk factors RDS

Prematurity

preinatal depression

male 

maternal diabetes

c section

multiple births

19

CCAM 

mass of pulmonary tissue in which there is proliferation of broncial structures at expense of alveolar devo

20

pathophysiology RDS

structural+ fxnl immaturity:

underdeveloped, un-elastic parenchyma

surfactant deficeincy

21

CXR meconium aspiration syndrome

patchy atelectasis or consilidation

22

main mechanistic cause of respiratory distress

inability to keep alveoli filled with air

23

treatment prenatal hydrops

thracentesis

thoraco-amniotic shunt

fetal lobectomy

induce delivery and perform resection

24

inadequate partioning occurs due eto 

abnormala or insufficient development of tacheoesophageal septum

26

significant production in surfact at ___wks

35 wks

(begins in cannicular period)

 

27

associated anomalies esophogeal aphasia and TEF

cardiac (VSD)

GI,

GU, 

Musculoskelatal

28

prevention of RDS

arrest preterm labor

antenatal bethamethasone - steroids stimulate type II pneumocytes and surfactant production
