determine level of pouch by X-ray taken upside down (so gas in pouch goes up), with a metal marker taped to the anus. colostomy for high rectal pouch and later repair, or a primary repair can be done right away if the blind pouch is almost at the anus

A

hernia on left and bowel up in chest. real problem is hypo plastic lung that still has fetal type circulation. repair must be delayed 3-4 days to allow maturation. babies are in respiratory distress and need endotracheal intubation, low pressure ventilation, sedation, and NG suction. difficult cases may need extracorporeal membrane oxygenation (ECMO).

Q

baby gets feeding intolerance and bilious vomiting. X-ray shows multiple dilated loops of small bowel and a ground glass appearance in lower abdomen. next steps to dx?

A

meconium ileum in cystic fibrosis! dx with gastrograffin enema-> microcolon, inspissated pellets of meconium in the terminal ileum. it is also tx: draws fluid in and dissolves the pellets.

Q

first born 3 week old gets non bilious projectile vomiting after each feeding. baby is hunger and eager to eat after he vomits. olive size mass in right quadrant.

A

pyloric stenosis! sonogram or palpating olive size mass is diagnostic. therapy begins with rehydration and correction of hypochloremic, hypokalemic metabolic acidosis. then amsted pyloromyotomy or ballon dilation.

Q

6-8 year old with persistent progressively increasing jaundice that is conjugated. next steps? dx? outcome?

A

biliary atresia! do serology and sweat test to rule out other causes. tx: do HIDA scan after 1 week of phenobarbital ( a powerful chloretic). if no bile reaches duodenum even with phenobarbital stimulation, surgical exploration is needed. outcome: 1/3 get long lasting surgical derivation, 1/3 need liver transplant after surgical derivation, and 1/3 need transplant right away.

A

18
Q

pregnant woman learns that her baby has congenital diaphragmatic hernia. may require?

A

extracorporeal membrane oxygenation (ECMO) if difficult. pulmonary hypoplasia, born in respiratory distress, need endotracheal intubation, low pressure ventilation, sedation.

19
Q

premature baby is first fed-> abdominal distention and dropping plt count. stop all PO feeds and place baby on antibx, IVF, IV nutrition. then he develops abdominal wall erythema and air in the portal vein. next steps?
