|
|
|
where do you find the congenital diaphragmatic hernia
|
posterolaterally
|
|
|
where does one see paradoxical respiration
|
in the eventration of the diaphragm up into the thoracic space
when the diaphragm contracts that half goes up |
|
|
the congenital diaphragmatic hernia (in the postero-lateral) is also known as
|
Bochdalek's
(1 in 2200) |
|
|
where do you see Morgagni's hernia
|
retro- or para- sternally
only 2% of diaphragmatic hernias herniation of intestine into pericardial sac |
|
|
what makes hiatal hernias suck
|
HCl
|
|
|
what is the orientation of the VAN
|
vein superior
arterery in the middle nerve inferiorly |
|
|
the VAN is located in which part of the rib
|
costal groove, inferiorly
|
|
|
the VAN is located between which muscles
|
the inner intracostals
and the innermost intracostals |
|
|
what is a thoracotomy
|
in incision into the pleural space
|
|
|
the internal thoracic artery divides to form the
|
epigastric and musculophrenic aa.
|
|
|
what are the two pleural recess
|
costomediastinal
costodiaphragmatic |
|
|

8th intercostal space
mid-axillary line just above the rib |
|
|
where do you find the superior and inferior tracheobronchial lymphatic nodes
|
above and below the carina
|
|
|
tracheo-esophogeal fistula
|
the proximal part of the esophagus ends blindly- the inferior bit it should be continuous with forms an atresia to the tracheal tube due to defective development of the tracheo-esophageal septum
(1 in 3000 births, common in males) may be part of a suite of defects known as VACTERL |
|
|
TEF 'H' type
|
both the proximal 'blind end' part of the esophagus AND its inferior part fistulate to the trachea
may be associated with exessive amniotic fluid because it cant get to the intestines |
|
|
what week does surfactant production begin
|
20th
fetuses born 22-26 have enough to survive |
|
|
what can you do for RDS
|
exogenous surfactant or corticosteroids
glucocorticoids during pregnancy accelerate fetal lung movements (which causes aspiration of amniotic fluid, stimulates lung development) and surfactant production |
