Chapter 19+20
How does should a nurse manage spontaneous abortion?
Constant Monitoring, Support Interventions
Continue Monitoring
* Passage of products of conception
* Vaginal bleeding*
* Pad count
* Pain level
* Preparation for procedures
* Medications
Support
* Physical and emotional
* Stress that woman is not the cause of the loss
* Verbalization of feelings
* Grief support
* Referral to community support group
*gushing, blood clots; more remnants
Threatened Spontaneous Abortion
Assessment findings
* Slight vaginal bleeding present in early pregnancy
* No cervical dilation
* Mild abdominal cramping
* Closed cervical os
* No passage of fetal tissue
Diagnosis
- Vagina, ultrasound to confirm if sac is empty 
- Declining maternal serum, hCG and progesterone levels to provide additional information about viability of pregnancy
Therapeutic management
- Conservative, supportive treatment
- Possible reduction in activity in conjunction with nutritious diet and etiquette hydration 
Complete Spontaneous Abortion
(Passage of all products of conception)
Assessment findings:
- History of vagina bleeding in abdominal pain
- Passage of tissue with subsequent decrease in pain and significant decrease in vagina bleeding
Diagnosis
-Ultrasound demonstrating an empty uterus
Therapeutic management
- No medical or surgical intervention necessary
-Follow up appointment to discuss family planning 
Inevitable Spontaneous Abortion
Assessment findings
* Vaginal bleeding
* Rupture of membranes
* Cervical dilation
* Strong abdominal cramping
* Possible passage of products of conception
Diagnosis
- Ultrasound and the hCG Levels to indicate pregnancy loss
Therapeutic management
- Vacuum Curettage of products of conception are not passed to reduce risk of excessive bleeding and infection 
- Prostaglandin analogues, such as misoprostol to empty out uterus of retain tissue (Only used in fragments are not completely passed)
Missed Spontaneous Abortion
Assessment findings
* Absent uterine contractions
* Irregular spotting
* Possible progression to inevitable abortion
Diagnosis
- Ultrasounds identify projects of conception in Uterus
Therapeutic management
- Evaluation of uterus, but using suction Curettage during first trimester, dilation and evacuation during second trimester 
Incomplete Spontaeous Abortion
Assessment findings
* Heavy vaginal bleeding
* Intense abdominal cramping
* Cervical dilation
Diagnosis
* Ultrasound demonstrating their products of conception still in Uterus
Therapeutic management
- Client stabilization
- Evaluation of uterus via D&C or prostaglandin analogue 

What to assess for an spontaneous abortion?
- Vaginal bleeding*
- Cramping or contractions
- Vital signs
- Continuous monitoring
- Pain level
- Patient understanding
- Provide support
*Is it a bright or dark red
Saturation of pad
How often must she change pad
saturated pad within 1 hour is SIGNIFICANT
What are the medications used for spontaneous abortion?
- Misoprostol (cytotec)
- Mifepristone (RU-486)
- Dinoprostone (cervidil)
What is the hallmark sign of ectopic pregnancy?
Ectopic Preganancy: Eggs implants outside of the uteris.
Abdominal pain with spotting within 6 to 8 weeks after missed menses.
What are the laboratory and diagnostic findings of ectopic preganancy?
Transvaginal Ultrasound
Serum Beta hCG
Absence of hCG indicated no pregnancy.
Include additional testing to prevent rupture.
What is the therapeutic management of ectopic pregnancy?
Meds, Surgery
Medical: drug therapy (methotrexate*, prostaglandins, misoprostol, and actinomycin)
Surgery if rupture (salpingostomy)
Rh immunoglobulin
*methotrexate slows down the immune system and reduces inflammation
*Salpingostomy - removal of fallopian tube (unilateral or B/L depending on situation and maternal age)
*Rh immunoglobulin is administered if the women is Rh-
What is the therapeutic management of Gestational Throblastic Disease?
Gestational Thromoblastic Disease (GTD) is when the egg and sperm produces an empty embryo. Two types: Hydatidiform Mole (Placental development)  and Choriocarcinoma (trophoblast) . Cause is unknown. PREGNANCY IS NOT VIABLE
Dilatation & curretage (D&C)
* Immediate evacuation of uterine contents
Long term follow up and monitoring of hcG levels
* Check hcG levels every week for 3 consecutive weeks until hcG serum levels are undetectable, then monthly for 1 year
Chest radiograph every 6 months
Prophylactic chemotherapy
Choriocarcinoma
NO PREGNANCY FOR 1 YEAR
* Pregnancy within 1 → risk for hemorrhage
Use birth control for the duration of that year
*Intervention: D&C
Hydatiform Mole
GTD
Disorder of placental development
COMPLETE MOLE
* Benign neoplasmic tissue coming from gestation, not mother
* Mole contains no fetal tissue and develops from an “empty egg,” which is fertilized by normal sperm
* The embryo is not viable and dies, No circulation is established and no embryonic tissue is found.
* Associated with the development of trio carcinoma
Uterine enlargement, greater than expected for gestational dates, hyperemesis and preeclamptic symptoms
PARTIAL
* Triploid karyotype (69 chromosomes, Since to sperm cells, have double contribution by fertilizing the oven
* Women present clinical features of mist or incomplete abortion, including: Vagina bleeding, and a small or normal size for date uterus 
Clinical Manifestations

How to manage preeclampsia without severe features?
Management for mild symptoms:
Home
* Mild BP - place in bedrest or in side-lying postion
* monitor BP daily every 4-6 hrs/day, report for increased readings
* record daily fetal movement count, report for decrease in movement

* encourage to drink six to eight 8-oz glasses of water daily
* go to the hospital if the home management fails to lower BP
Hospitalization
* monitor closely for s/s of severe preeclampsia or impending eclampsia
* give magnesium sulfate during labor
Management continues until the pregnancy reaches at least 37 weeks’ fetal gestation, fetal lung maturity is documented, or complications that immediate birth.
