|
What is a diaphragmatic hernia?
|
-herniation of abdominal organs thru the diaphragm
-diagnosed at birth or prenatally |
|
Why is prompt recognition of a diaphragmatic hernia essential?
|
bc of possible respiratory distress, dyspnea, tachypnea, impaired cardiac output

Immediate txment of gastroschisis?
|
-protection of exposed viscera: 1st b4 do anything else. Trying to maintain bowel so it doesn't die.
-warm,sterile saline-soaked dressings,plastic • Radiant warmer and IV fluids – To replace heat and fluids lost through exposed viscera • Blood cultures prior to antibiotics – Broad spectrum antibiotics to prevent infection • NG/OG tube to prevent distension |
|
Clinical therapy gastroschisis?

other anomalies
-Trisomy 13,18,21 -craniofacial, diaphragmatic abnormalities |
|
What is Hirschsprung dz?
|
• Congenital Aganglionic Megacolon
– Parasympathetic ganglion cells are absent in the distal colon,from the anus and continuing up the colon (portion of bowel w/ no ganglion cells which is what czs peristalsis so cannot pass stool) – Absence of ganglion cells causes decreased peristalsis at the site and inability to pass stool – Stool distends the colon-’megacolon’ |
