Failed Pregnancy-Kaplan Flashcards
Risk of maternal death assoc with abortion increases with
advancing gestational age
What is the most common first trimester method of Induced abortion?
Vacuum curettage - D & C
- cervical canal is tpered with metal dilators or hygroscopic osmotic dilators such as laminaria
- pt gets prophylactic antibiotics
What is a medical abortion?
induced using oral 1) Mifepristone–a progesterone antagonist
2) oral Misoprostol
- pt. will abort in 3 days
Which procedure carries the risk of Clostridium sordelli infection?
Medical abortion
What is the most common second trimester method?
D and E - Dilation and Evacuation - dilate the cervix using laminaria - the mm of dilated cervix will go along with the # weeks of gestation
-early can make morcellated fetus
Intact D and E involves more advanced pregnancies
involves 2 or more days of laminaria treatment to widen cervix allowing breech delivery of fetus under U/S guidance w. decompression of the calvaria with fetus rest of fetus otherwise intact—-> basically a partial birth abortion
Complications of D and E
uterine perforation, retained tissue, hemorrhage, infection, and rarely DIC
Labor Inducing Methods
-prostaglandins (PGF 2alpha)
-vaginal PGE2 (Cervidil)
-15-methyl-PGF2alpha ((Herbamate)
-PGE1 (Misoprostol)
….all strengthen uterine contractions
Which one will allow delivery of a live fetus?
prostaglandin analogs—kill fetus via KCL or digoxin intracardiac
Complications of inducing labor
immediate retained placenta, hemorrhage, infection
Late complications: cervical trauma resulting in cervical insufficiency
What are the first trimester induced abortions?
Surgical - D and C
Medical - Mifepristone
What are the second trimester methods of induced abortion?
Surgical- D and E
Medical - induction of labor contractions
Which method of induction can be done at any trimester?
hysterotomy or hysterectomy
Early pregnancy bleeding: On speculum exam if the internal cervical os is closed, what is the diagnosis?
lower genital tract lesion
missed abortion- embryo has stopped growing (incental finding)
threatened abortion - vag bleeding- viable pregnancy - can give Misoprostol (PGE1)
Early pregnancy bleeding: On speculum exam, if the internal cervical os is opened, then it is
Threatened
Inevitable abortion- can be live or dead- matter or time
Fetal demise - fetal death after 20 weeks before birth
no movement for 24 hrs
nothing on sonogram
Antenatal demise occurs before birth
Intrapartum demise occurs after the onset of labor
What is the complication of fetal demise?
DIC - four weeks after demise; fetus uses up the platelets while dying (PLT down while D-Dimer, fibrin split products increasing)
- if mom wants to let it pass on its own then do weekly PLTS
- -diagnosed w. color Doppler/ U/S to see chest
Ruptured ectopic management
Triad (unilateral pelvic pain, amenorea, vaginal bleeding) plus hypotension and tachycardia To diagnose ectopic pregnancy: 1. do vaginal sonogram 2. serum hCG> 1500 Tx: immediate laparotomy
If beta hCG is
hCG> 1500 plus sac
laparoscopy–linear salpingoscopy
Salpingotomy- taking out the fallopian tube; follow weekly
