Q

Treatment of PCOS depends on the desired outcome…

A

•For those desiring fertility, ovulation induction using clomiphene citrate (Clomid) is begun
oPatients with PCOS are particularly resistant to ovulation induction. The probability of induction can be increased with weight loss and the concomitant use of corticosteroids. Also metformin if they have diabetes

•If not interested in fertility, cycle progestins or Depo-Provera should be used to decrease the risk of endometrial hyperplasia and cancer secondary to unopposed estrogen

o± Fever

oExamination reveals lower abdominal and pelvic pain and cervical motion tenderness (chandelier sign)

oPurulent and/or malodorous discharge and inflammation of Bartholin’s or Skene’s glands may be present

oAn adnexal mass may indicate a tubo-ovarian abscess

44

oTreatment of choice is often ampicillin (2g IV q4h), gentamicin, plus clindamycin or metronidazole

*If more SERIOUS:
•Drainage of TOA using ultrasound guidance or laparoscopy if no response within 48 hours of medical therapy

  • Unilateral salpingo-oophorectomy is considered as a curative therapy for unilateral TOA

A

Chromosomal abnormalities- 60%

52
Q

_____ is the termination of pregnancy, by any means, before 20 weeks gestation, less than 500g, or less than 25cm.

A

Abortion

53
Q

Risk factors for a spontaneous abortion are:

A

Smoking, infection, maternal systemic disease (DM, thyroid, PCOS), immunologic parameters, drug use, maternal/paternal age, increasing parity, high BMI, heavy caffeine use, submucosal fibroids, uterine abnormality (septum, bicornuate), Asherman’s (uterine synechiae/atresia), history of prior SAB

54
Q

Classifying spontaneous abortions:

A
  1. Threatened: Bleeding + Unopened cervix + Product not passed
  2. Inevitable: Bleeding + Opened cervix + Product not yet passed but no way to maintain pregnancy
  3. Incomplete: Bleeding + Opened cervix + Partial product passage
  4. Complete: Bleeding + Opened cervix + Product passed
  5. Missed: NO bleeding + Unopened cervix + No passage of product (fetal demise has occurred without symptoms).
55
Q

“Treatment” of spontaneous abortion involves:

A

oIf the pregnancy has been definitively determined to be no longer viable, the uterus must be emptied

oIf the pregnancy is early and the patient is managed expectantly (allow the products of conception to pass naturally), careful follow-up with pelvic examinations, serial hCG titers, and transvaginal ultrasonography can be used to determine whether the abortion is complete

oDilation and curettage also may be necessary to ensure complete emptying of the uterus or as one form of induced abortion. Morbidity is caused by uterine perforation or cervical laceration

56
Q

Rhogam necessary when mother is Rh negative and:

A
  • At any time in a pregnancy if she has vaginal bleeding
  • If she miscarries or has an ectopic pregnancy
  • If she undergoes a procedure such as an amniocentesis
  • At 28 WEEKS and at delivery is baby is Rh positive
57
Q

Large placental separations may result in:

A

-Premature delivery, uterine tetany, DIC, and hypovolemic shock

58
Q

Classic presentation of placental abruption is:

A

Third-trimester vaginal bleeding associated with severe abdominal pain and/or frequent, strong contractions

*Dx is mainly clinical. Few picked up on US. May use US to rule out previa.

59
Q

Treatment of placental abruption involves:

A
  1. Delivery in severe cases
  2. Stabilize the patient and hospitalize with continuous fetal monitoring. Prepare for possible hemorrhage with placement of large bore IVs, infusion of LR, preparation of whole blood or PRBCs)
60
Q

_____ is a pregnancy that implants outside the uterine cavity.

A

Ectopic

*Usually fallopian tube

61
Q

PE for ectopic reveals:

A

Adnexal mass that is often nontender, a uterus that is SGA, and bleeding from cervix.

-If ruptured patient may be HYPOtensive, unresponsive, or show signs of peritoneal irritation secondary to hemoperitoneum

62
Q

Labs in ectopics:

A

The classic finding is a β-hCG level that is low for gestational age and does not increase at the expected rate

  • In patients with a normal intrauterine pregnancy, the trophoblastic tissue secretes β-hCG in a predictable manner that should lead to doubling (or at least an increase of ≥⅔) approximately every 48 hours
  • An ectopic pregnancy has a poorly implanted placenta with less blood supply than in the endometrium, thus the level of β-hCG does not double every 48 hours
63
Q

US for ectopic may reveal adnexal mass

A

A gestational sac with a yolk sac seen in the uterus on ultrasound indicates an IUP

64
Q

For patients that cannot be definitively diagnosed with an ectopic v. IUP should receive serial hCGs q 48h

A

As a guideline, an IUP should be seen on transvaginal ultrasonography with a β-hCG between 1,500-2,000 mIU/mL. A fetal heartbeat should be seen with β-hCG > 5,000 mIU/mL

65
Q

Treatment of ectopic involves:

A

oIf a patient presents with a ruptured ectopic pregnancy and is unstable, the first priority is to stabilize the patient with IV fluids, blood products, and pressors if necessary

oThen take to the OR where exploratory laparotomy can be done to stop the bleeding and remove the ectopic pregnancy

oIf the patient is stable with a likely ruptured ectopic pregnancy, the procedure of choice is exploratory laparoscopy that can be performed to evacuate the hemoperitoneum, coagulate any ongoing bleeding, and resect the ectopic pregnancy

66
Q

If patient has an unruptured ectopic, an option other than surgery is:

A

Methotrexate therapy for treatment of the ectopic pregnancy is usually used for uncomplicated, nonthreatening, ectopic pregnancies.

67
Q

_______ is defined as abnormal implantation of the placenta over the internal cervical os.

A

Placenta previa

oComplete Previa = the placenta completely covers the internal os
oPartial Previa = the placenta covers a portion of the internal os
oMarginal Previa = the edge of the placenta reaches the margin of the os
oLow-Lying Placenta = implanted in the lower uterine segment in close proximity but not extending to the internal os
oRarely, a fetal vessel may lie over the cervix known as a vasa previa

68
Q

Placenta previa fetal risks:

A

Preterm delivery and its complications, PPROM, IUGR, malpresentation, vasa previa, congenital abnormalities

69
Q

_____ is the abnormal invasion of the placenta into the uterine wall.

A

Placenta Accreta

70
Q

In patients with known or suspected previa, _____ sonography is avoided

A

Transvaginal

71
Q

How is placenta previa managed?

A

oCommonly managed with strict pelvic rest (i.e., no intercourse) and modified bed rest
•Some clinicians wont institute this until the patient presents with sentinel bleed

• However, 70% of patients with placenta previa have recurring bleeding episodes and will require delivery before 36 weeks

•Prepare for preterm delivery:
*Prior to 34 weeks gestation, betamethasone is given to promote fetal lung maturity

**Tocolysis is also used to assist in prolonging the pregnancy up to 34 weeks of gestation. Occasionally it is used past 34 weeks to help control bleeding

72
Q

Rupture of membranes before ___ weeks is considered preterm rupture of the membranes. Rupture of the membranes occurring before the onset of labor is termed premature rupture of the mebranes.

A

37

*If the 2 occur together it is called preterm premature rupture of the membranes- PPROM

73
Q

Prolonged PPROM has been associated with increased risk of:

A

Chorioamnionitis, abruption, and cord prolapse

74
Q

Diagnosis of ROM is done by:

A

History of leaking vaginal fluid, pooling on speculum exam, and positive Nitrazine and fern tests

75
Q

Treatment of PPROM involves consideration of risks of prematurity v. infection.

A

Thus, ampicillin with or without erythromycin is recommended in the setting of PPROM

-Corticosteroids also currently recommended
oCommonly, if ROM occurs any time after 34-36 weeks, labor is induced/augmented

76
Q

Some preterm facts…

A
  • Infants born on the cusp of viability at 24 weeks have a greater than 50% mortality rate

-Tocolysis → the attempt to prevent contractions and the progression of labor
oOnly RITODRINE – a beta-mimetic agent – is FDA-approved for this purpose

oThe principal benefit from gaining 48 hours in a pregnancy is to allow treatment with steroids to enhance fetal lung maturity and reduce the risk of complications associated with preterm delivery
•Betamethasone, a glucocorticoid, can reduce the incidence of RDS and other complications from preterm delivery. Thus, prior to 34 weeks gestation, the advantage of treating with steroids need to be weighed against the risk of prolonging the pregnancy

oChorioamnionitis, nonreassuring fetal testing, and significant placental abruption are absolute indications to allow labor to progress,

77
Q

Non-reassuring patterns indicating fetal distress…

A

o Increased or decreased FHR, especially during and after a contraction
• Normal is 110-160 bpm
