12. Preg Complications Flashcards
Spontaneous abortion/Miscarriage
Ends before 20 weeks; 80% occur within 1st 12 wks; 1 in 5 pregnancies end in miscarriage
Preterm Birth
Delivery of live infant prior to 37 wks; Incidence = 5-10%
IUFD
Intrauterine Fetal Demise - Fetal death in utero after 20 weeks or > 500 grams
General categories of IUFD Causes
Maternal, Fetal, Placental
Stillbirth
Delivery of fetus after 20 wks without evidence of life; Most stillbirths are actually IUFDs because most don’t die during delivery
Single most important test for a reproductive aged female with abdominal pain
Pregnancy test
Induced abortion
Planned procedure
Spontaneous abortion
Passage of fetus
Complete abortion
Spontaneous abortion of all products of conception
Incomplete abortion
Spontaneous abortion where some tissue is retained
MC reason for ER visit d/t abortion
Incomplete abortion resulting in hemorrhaging
Threatened abortion
Less than 20 weeks with viable pregnancy, vaginal bleeding & CLOSED CERVIX
Inevitable abortion
Less than 20 weeks, vaginal bleeding & DILATED CERVIX; preg loss unavoidable
Missed abortion
Retention of a failed IUP
Septic abortion
Any type of abortion complicated by a pelvic infection
Recurrent abortion
2 or more consecutive or a total of 3 spontaneous abortions
MCC of abortion in 1st 10 weeks
Genetic abnormality; 70% trisomies (Trisomy 16 MC)
MCC of abortion in weeks 14-18
Less likely genetic; More likely = maternal illness, uterine abnormality; placental factor; incompetent cervix
S/Sx of Abortion
HCG not properly increasing (should double every 48 hr in 1st trimester)
Blighted Ovum
AKA Anembryonic pregnancy = Failed development of the embryo so that only a gestational sac, with or without a yolk sac, is present
Complications of Abortion
Hemorrhage (MC); Sepsis; Emotional/Psychological
Threatened abortion tx
Bed rest (no data to support); Pelvic rest (NO INTERCOURSE!)
Incomplete abortion tx
Type & Screen; Rhogam; OB consult; Prep for OR or D&C
What should happen if patient with incomplete abortion passes a lot of tissue & cervix is open?
Avoid surgery if tissue is passed.
Complete abortion tx
Cervix is closed; pain and bleeding decrease. U/S shows no IUP and no ectopic. Re-exam shows closed os. Eval need for transfusion; Cytotec & RTC in 1 wk
Missed abortion tx
Watchful waiting. Most terminate spontaneously after 2 wks. Intervention necessary if no change after 4 wks.
Tx: uterine curettage or D & C
Complication of Missed Abortion
Prolonged retention can result in DIC
Septic abortion pathogens
E. coli; Strep fecalis, and Clostridia perfringes
Septic abortion tx
Resuscitation, broad spectrum ABX; tetanus toxoid; Early evacuation of uterus
Leading cause of Pregnancy Related Maternal Death in First Trimester
Ruptured ectopic pregnancy leading to hemorrhage
High risk factors for Ectopic Pregnancy
Previous ectopic pregnancy; Tubal pathology & surgery; IUD
Why do IUDs increase risk of pregnancy?
IUD slows rate of egg travel, so ectopic common if IUD fails
Signs/Symptoms of Ectopic Pregnancy
Tenderness; Adnexal mass; Uterine changes; “The Triad” = Pain, Vag bleeding; Amenorrhea
Pitfalls in Dx Ectopic Pregnancy
Atypical/absent pain; Failure to recognize factors; Passage of uterine tissue
MCC of Death in Young, Healthy Pregnant Woman
Unrecognized ectopic pregnancy
MC location of ectopic pregnancy
Ampulla
Worst Ectopic Pregnancy Outcomes Location
Cornual
Dx of Ectopic Pregnancy
Quantitative hCG levels greater than 6000 and absence of gestational sac; OR transvaginal U/S
