Pt with recent surgery, no flatus, bowel moment, mildly distended abdomen/ decreased bowel sounds. How should they be ,=managed?
post op ileus self resolves
- antiemetics, bowel rest, and serial examinations

56
should a woman with blood type O who gives birth to an infant with blood type a or b be concerned? why or why not?
No because, A and B antigens will be present on fetal tissue ( in addition to RBC) neutralizing the hemolytic antibody response
- newborns will only have milder form of disease that can be managed with phototherapy, oral rehydration, exchange transfusion for severe cases
57

molding and caput, can be caused by malposition of fetus
Caput: swelling on baby scalp due to pressure from squeezing through pelvis in difficult delivery
Molding: changing of shape of head from squeezing through a small birth canal
59
signs of DIC, associated labs
- increased fibrinolysis causes:
—-lower fibrinogen (protein that helps form clots, low means you can’t form clots) and increased d-dimer
- low platelets

laparoscopy unless patient is hemodynamically unstable or large intraperitoneal bleed (laparotomy preferred for more emergent cases)
salpingectomy: removes fallopian tube, good if pregnancy is ruptured or tube is severely damaged
salpingostomy: unruptured distal tubal ectopic pregnancy, spares the tubes

92
Gonadal dysgenesis
ovaries are replaced by tissue called gonadal streak, no produciton of ovarian steroids ie estrogen, so no breasts, but internal and extern al gentialia are phenotypically female FSH LH elevted due to lack of negative feedback,
93
maternal serum alpha-fetoprotein (MSAFP) is elevated for
- fetal abdominal wall defects, open neural tube, and mutiple gestation
**major protein produced by fetal yolk sac, liver, and GI tract, measured at 15-20 wks
** when elevated need US to evaluate fetal anatomy
