Bleeding during pregnancy can be what?
Placenta Previa
Membranous insertion of umbilical cord
Vomiting in pregnancy with weight loss, electrolyte, and dehydration
Hyperemesis Gravidarum
This is diagnosed with two markers
BP over 140/90
Protein in urine
Gestational Diabetes
When is gestational diabetes usually diagnosed?
24-28 weeks
Mother and father different blood types
Blood incompatibility
Mother attacks newborn. Rhogam given at 28 weeks
Biggest killer in pregnant women is
Hemorrhage
Bag of water ruptures early prior to term
PROM
Higher risk of complications
Multiple Gestation
Name some 1st Trimester Disorders
Abortion Therapeutic
SAB
Ectopic Pregnancy
Abortion usually involves D&C
Loss of products of conception prior to viability
Abortion
Purposeful termination
Therapeutic Abortion
Usually involves D&C
SAB is _____________loss of pregnancy
Unintentional
Implantations in a site other than the uterus
May result in severe bleeding and requires surgery
Ectopic Pregnancy
1st trimester commonly due to what?
Genetic Abnormalities
2nd Trimester more likely related to maternal disorders
Cervix is not dilated and placenta still attached to uterine wall
Threatened
Placenta has separated from uterine wall, cervix has dilated, and amount of bleeding has increased
Imminent
Embryo or fetus has passed out of the uterus but placenta remains
Incomplete
Threatened
Inevitable
Incomplete
Missed
Habitual
Types of Spontaneous Abortions
Continued monitoring
Vaginal bleeding, pad count, passage of products of conception, pain level, preparation for procedures, medications
Abortions
Important ti support in abortions
True
Physical and emotional. Stress woman is not cause of the loss. Verbalization of feelings, grief support, referral to community support group
Implantation of fertilized ovum in site other than the uterus.
Mortality declined almost 90%
Initially symptoms of pregnancy
Positive HcG present in blood and urine
Chronic villi grow into tube wall or implantations site
Rupture and bleeding into the abdominal cavity occurs.
Ectopic Pregnancy
Ovum implantation outside of the uterus
Obstruction to or slowing passage of ovum through tube to uterus
Ectopic Pregnancy
Therapeutic Management of Ectopic Pregnancy
Medical:
Drug therapy- Methotrexate, Prostaglandins, misoprostol, and actinomycin.
Surgery if rupture.
Rh immunoglobin if woman is Rh- (Rhogam)
Nursing Assessment for Ectopic Pregnancy
Hallmark sign: abdominal pain with spotting 6-8 weeks after menses
Contributing factors
Lab/ Diagnostic testing: Transvaginal ultrasound, serum beta Hcg, additional testing to rule out other conditions
Most common site for ectopic pregnancy is
The fallopian tubes. Hence name tubal pregnancy.
Pathologic proliferation of trophoblastic cells
Includes hydatidiform mole
Invasive mole - Chorioadenoma destruens
Choriocarcinoma a form of cancer
Initially clinical picture similar to pregnancy
Gestational Trophoblastic Disease
Classic Signs
Uterine enlargement greater than gestational age
Vaginal Bleeding
Pregnancy is a vesicular swelling of placental villi and usually absence of an intact fetus
Hydatidiform Mole
Malignant, fast growing tumor that develops from trophoblastic cells- cells that help embryo attach to the uterus and help form the placenta
Choriocarcinoma
Therapeutic Management of Gestational Trophoblastic Disease
Immediate evacuation of uterine contents D&C
Long term follow up and monitoring of serial hCG levels
Nursing Assessment of Gestational Trophoblastic Disease
Clinicals manifestations similar to spontaneous abortion at 12 weeks
Ultrasound visualization
High HcG Levels
Nursing Management of Gestational Trophoblastic Diseases
Preoperative preparation
Emotional support
Education: Treatment, serial hCG monitoring, prophylactic chemotherapy
Classic signs present in about 50% of cases
May pass hydropic vesicles
Hyperemesis gravidarum
Higher serum hCG levels
Therapy is suction evacuation of the mole
- Uterine curettage for removal of placental fragments
- Hysterectomy for excessive bleeding
Gestational Trophoblastic Disease
Common sign is vaginal bleeding, often brownish, but sometimes bright red. Sometime hydropic vessels are being passed.
Hydatidiform Mole
Possible causes include
Cervical trauma
Infection
Congenital cervical or uterine anomalies
Increased uterine volume(as with a multiple gestation)
Associated with repeated second trimester abortions
Incompetent Cervix
Diagnosis: Positive history of repeated second trimester abortions
Premature dilatation of cervix and unknown
Possibly due to cervical damage
Therapeutic management
Bed rest, pelvic rest, avoidance of heavy lifting
Cervical cerclage
Incompetent Cervix
Cerclage
Shirodkar procedure for incompetent cervix
Modification of it by McDonald
Reinforces the weakened cervix
Purse- string suture is placed in the cervix
Done in 1st trimester or early 2nd trimester
Cesarean birth may be planned
Suture may be cut at term and vaginal birth permitted
Incompetent Cervix Tx : Surgical Procedures
More difficult less common, as it passes through the walls of the cervix, usually permanent stitch, must have c/s
Shirodkar
Placed at 16-18 week, removed at 37 weeks for natural delivery most common and least invasive
McDonalds
Nursing Assessment for Incompetent Cervix
Risk Factors
Pink Tinged vaginal discharge or pelvic pressure
Cervical shortening via transvaginal ultrasound
Nursing management for incompetent cervix
Continue surveillance and close monitoring for preterm labor
Emotional support
Education
Inserted in the cervix to prevent preterm cervical dilatation and pregnancy loss. After placement the string is tightened and secured anteriorly.
Cerclage
Painless bleeding with relaxed uterus
Avoid vaginal exams
Occurs when the placenta implants near or over the cervical os- Vaginal exams prohibited
Painless bleeding in the 3rd trimester
Placenta Previa
Complications of Placenta Previa
Hemorrhage
Fetal Distress/Demise d/t intrauterine hypoxia
Intrauterine Growth Restriction
Preterm Delivery or Premature rupture of membranes
Nursing Management client with Placenta Previa
Monitoring of maternal fetal status \
Vaginal bleeding and pad count
weight pads
Avoid vaginal exams
FHR
Support/ Education: Fetal movement counts, effects of prolonged bed rest; s/s to report
Preparation of possible cesarean birth
Name types pf Placenta Previa
Low Lying
Partial Placenta previa
Total placenta previa
Premature detachment of the Placenta
Abruptio Placenta
Vaginal bleeding, mild uterine tetany- neither mother or fetus in distress
Mild Abruptio Placenta
Uterine tenderness/ tetany with or without external bleeding ; mother not in shock but fetal distress may be present
Moderate Abruptio Placenta
Uterine tetany; maternal shock, fetus dead or severely compromised
Severe Abruptio Placenta
Nursing Assessment Abruptio Placenta
Risk Factors
Bleeding- Dark red
Pain- Knife like, uterine tenderness, contractions
Fetal movement and activity(decreased)
FHR
Lab/ Diagnostic Testing: CBC, fibrinogen levels, PT/ aPTT, type and cross-match, nonstress test, biophysical profile
Tetany contractions longer than 60 Seconds
Helps to reduce blood loss when nml(blood clot formation)
Fibrinogen
Name Precipitating factors for Placental Abruption
Blunt trauma to abdomen
Drug abuse; especially cocaine
PIH
PROM
Smoking
Multifetal Pregnancies
Nursing management for Placental Abruption
Tissue perfusion
-Left lateral position, strict bed rest, oxygen therapy, vital signs, fundal height, continuous fetal monitoring
Support/ Education: Empathy, understanding, explanations, possible loss of fetus, reduction of recurrence
Want baby out ASAP to help prevent MOM from bleeding out
What position improves circulation, giving nutrient- packed blood an easier route from your heart, to the placenta to nourish your baby
Left Lateral Position
Labor contractions with subsequent cervical changes prior to 36.6 weeks
Preterm Labor
PROM
Premature rupture of membranes prior to onset of labor
PPROM
Preterm premature rupture of membranes- rupture of membranes prior to 36.6 weeks
Without ucs
Name Preterm Labor Medications
Terbutaline
Indomethacin
Nifedipine
Magnesium Sulfate
Betamethasone
