Pregnancy Complications Flashcards
(86 cards)
Spontaneous abortion/miscarriage
a pregnancy loss occurring before 20 weeks gestation
different types of spontaneous abortion
threatened, inevitable, incomplete, missed, and complete abortion
RF spontaneous abortion
maternal disease (e.g., diabetes mellitus, thyroid disease, thrombophilia, lupus anticoagulant), being severely overweight or underweight, structural abnormalities of the uterus, and exposure to teratogens or infections
dx spontanenous abortion
Diagnosis is made by pelvic examination, serially decreasing human chorionic gonadotropin levels, and transvaginal ultrasound showing inappropriate development or fetal demise
threatened abortion
vaginal bleeding with or without uterine contractions in the presence of a closed cervical os
inevitable abortion
vaginal bleeding and a dilated cervical os without passage of any fetal tissue
Products of conception can be felt or visualized through the cervical os
incomplete abortion
vaginal bleeding and a dilated cervical os with the passage of some but not all of the products of conception
missed abortion
death of the fetus before 20 weeks gestation, retained products of conception, and a closed cervical os
there is no history of vaginal bleeding
complete abortion
complete passage of the products of conception out of the uterus and cervix. On physical examination, the cervical os is closed and the uterus is small
tx for specific types of abortion
inevitable, incomplete, or missed abortion is managed with surgical uterine evacuation (e.g., dilation and curettage), pharmacologic uterine evacuation (e.g., mifepristone followed by misoprostol or misoprostol only), or expectant management. Retained products of conception after administration of misoprostol may be treated with surgical evacuation or a second round of misoprostol
when is expectant management an option for spontaneous abortion
Expectant management is an option for patients at < 14 weeks gestation who are stable and have no signs of infection.
Retained products of conception after 4 weeks of expectant management should be treated with surgical evacuation
dose for Rh immune globulin
A 50 mcg dose is given if the abortion occurred before 13 weeks gestation.
Otherwise, the standard 300 mcg dose is given
when does serum hCG usually come back to normal
Serum human chorionic gonadotropin typically returns to normal within 6 weeks after a completed abortion and may be monitored serially after expectant management or pharmacologic evacuation
pelvic rest for abortion
Pelvic rest is recommended for 2 weeks following an abortion
what should always be offered to ppl w spontaneous abortion
counseling
The most common cause of spontaneous abortion
fetal chromosomal abnormalities
what suggests viability of pregnancy if threatened abortion
Incremental increases in serum hCG and elevated progesterone concentrations suggest viability of the pregnancy
Women with incomplete abortions should be monitored for
development of endometrial infections and complete expulsion of the products of conception
septic abortion
an infection of partially retained products of conception
diagnostic workup in all patients with first trimester bleeding
CBC, quantitative serum hCG, blood type, and transvaginal ultrasound.
Ectopic pregnancy
a pregnancy occurring outside of the uterus
where do most ectopic pregnancies occur
in the Fallopian tubes
RF ectopic pregnancy
previous ectopic pregnancy (most important), prior tubal surgery, pregnancy occurring with an intrauterine device in place, and prior pelvic inflammatory disease
sx ectopic pregnancy
Lower abdominal pain and vaginal bleeding are the most classic symptoms. The vaginal bleeding is usually heavy and painful
