Test 4: Intrapartum complications/Induction/Antepartum Dx/Monitor Strips/Age/Abuse Flashcards
What are the twin demons and what do they have to do with the 200% increase in blood transfusions in the last 10 years (during childbirth)?
Denial and Delay of interventions of hemorrhages.
Denial because it’s not very obvious a lot of the time… just a steady flow, nothing overtly screaming “bleeding-out.”
Delay due to the denial. Delay of doing something about it… 1/2 of the 2-3 women who die every day are considered preventable.
What is the U.S. ranked in terms of maternal morbidity?
47th
What sort of things can we do to prevent loss of life due to hemorrhage?
- Recognizing the problem EARLY
- Mobilizing the team and having good communication.
- Having a sense of empowerment… knowing what’s right and advocating for it… understanding your role in that.
- Assessing acurate VS and quantifying the estimated blood loss (EBL).
- Being PREPARED for an Emergency! Having hemorrhage drills and having a set protocol in place.
During the first trimester what are the most common causes of hemorrhage?
- SAB
- Ectopic
- Gestational Trophoblastic Disease
- Cervical Insufficiency
80% of fetal demise occur in the 1st trimester and are usually fetal-related (genetic/ faulty implantation/ endocrine imbalance).
What are the most common causes of hemorrhage during the 2nd and 3rd trimesters?
- Placenta Previa
- Placenta Abruption
Fetal demise after 20 weeks is usually maternally-related (uterine anomalies/ Infections/ Maternal disease [CVD, DM]/ Substance abuse [esp. cocaine])
25-30% of all pregnancies have some bleeding.
What classification of SAB is presented as bleeding, cramping/low back pain with a closed cervix?
Threatened.
ANY possible/actual SAB we need to asses the patient and support them where they are at… grieving, listening.
We can help them know what to expect emotionally or physically… they will react differently. PVH refers each and every fetal loss patient to bereavement support resources.
What classification of SAB is presented as increased bleeding, cramping with a dilating cervix?
Imminent.
What classification of SAB is presented as having experienced a SAB but not all of the tissue was expelled?
Incomplete.
Worry about hemorrhage and infection.
What increases a woman’s chance of SAB and what classification do they fall under?
Habitual.
Greater than or equal to 3 SAB’s… after your 2nd your risk increases of more.
What does HCG stand for?
Human Chorionic Gomadotrophin
Hormone produced early in pregnancy by the placenta; detection in the urine and serum is Dx.
If too low could be ectopic, if too high could be gestational trophoblastic disease or in regards to SAB, if levels have not continued to drop may have retained tissue.
What do we use to visual the fetus if risk of SAB?
What are some medications that are commonly used with this occurrence?
Cytotec. This is used to reduce the risk of ulcers from NSAID use. It is contraindicated in pregnancy bc it causes preterm labor contractions by irritating the cervix. Since this is what we need after/during an SAB, it is used to insure all tissue has been expelled.
Antibiotic.
Rhogam. Depending on the maternal blood type.
Besides SAB management with medications, what other method may be used to prevent hemorrhage and infection?
D and C - Dilation and Curettage
Removing anything that is retained in the uterus.
This procedure is also a possible risk for hemorrhage in itself so we need to WATCH their I’s and O’s for possible hemorrhage clues.
Must be on pelvic rest for ? depends on provider, at least a few days.
What is the medication Methotrexate used for?
What is Terbutaline used for?
Dissolving the small, still growing, embryo of an ectopic implantation.
It’s a cytotoxic drug.
Option for medical management depending on mom’s risk factors and stage at Dx… and risk of fallopian tube rupture.
Terbutaline is a smooth muscle relaxer (β2-adrenergic agonist) that is often used as a tocolytic.
Some causes of ectopic pregnancy:
- Scarring due to infection or surgeries or endometriosis or pelvic inflammatory disease
- Hormonal imbalances that may cause a delay of arrival of zygote to the uterus.
- Congenital malformations
Signs and symptoms of ectopic pregnancy:
Usually becomes symptomatic with pain around the 6- 8 week gestation.
Spotting to heavy bleeding
Cramping to SHARP one-sided abdominal pain
Fever
Decreased H and H due to hemorrhage.
Shock symptoms also related to blood loss.
What can be used to Dx an ectopic pregnancy?
What is a medical option involving a cytotoxic drug?
Ultrasound
hCG levels: if it hasn’t doubled in 72 hours then not enough room for the embryo to grow.
Can use methotrexate to dissolve the embryo.
What are some nursing considerations regarding an ectopic pregnancy?
- Volume replacement, I and O’s to keep track of possible hemorrhage should the fallopian tube rupture.
- Emotional support. Loss of life, possible loss of fertility or at least decreased fertility.
- Life-threatening to the mom.
What is the disease that is a neoplastic disorder that originates in the placenta?
Gestational Trophoblastic Disease.
- Gestational tissue is present but pregnancy is non-viable.
- Begins with conception: chorionic villi overgrow… leading to elevated levels of hCG.
This disease is often diagnosed around 12 weeks of gestation and occurs in about 1/1500 pregancies:
Gestational Trophoblastic Disease.
Happens most in teens and peri-menopausal women.
What is the cause of GT Disease?
How is it diagnosed?
Unknown… mabye:
genetic component
protein deficiency
advanced maternal age
Dx:
Ultrasound/FHTs
Spontaneous abortion of mole (us around 20 wks)
What are the two types of gestational trophoblastic disease?
- Partial: fetal tissue is often present but non-viable.
2. Complete: no fetal tissue, no genetic material, all chromosomes are paternal?
What are the signs and symptoms of gestational trophoblastic disease?
- Normal pregnancy symptoms initially
- Dark brown spotting/bleeding
- Elevated levels of hCG = HYPERemesis and higher fundal height
- Signs and symptoms of preeclampsia prior to 20 wks
- No fetal heart tones
Due to the risk for hemorrhage, what are risks and treatments for GTD?
- Can give oxytocin to prevent hemorrhage
- Can perform D and C
- Risk for hysterectomy if the chorionic villi grew into the uterus. Cannot separate these tissues… just continues to bleed.
What sort of emotional support may be needed regarding the outcome of GTD?
Follow up should consist of:
- Monitoring hCG levels
- Monitoring for DIC
- They should avoid pregnancy for at least 6 mos
- Close follow-up at 12 mos
- Possible chemotherapy?
Emotional support:
Scary Dx, increased risk for progression to choriocarcinoma.
Educate about future family planning.
This condition is presented with a dilating cervix in the absence of uterine contractions:
What are some causes of this?
Cervical insufficiency.
Caused by a structural defect or previous injury to cervix maybe from cancer or HPV… cone biopsy, colposcopy, LEEP (used as part of the diagnosis and treatment for abnormal or cancerous conditions).
At what gestation is a woman most at risk for cervical insufficiency?
Weeks 16-24.
Signs and symptoms:
- Painless dilation
- Effacement
- Spotting
- Cramping
How do we manage cervical insufficiency?
Decrease activity (including sex and maybe on bed-rest)
Cerclage procedure: (stitching the cervix closed)
Follow-up: frequent assessments to watch for signs of cervical progression, infection, and labor.
Induction/ expectant management: This is due to the risk of rapid labor/delivery.
What are some complications from an abnormal location of placental implantation?
Placenta Previa may have the following complications:
- Abruption
- Hemorrhage
- Accreta - placenta grows too deep in to the uterine wall… won’t detach after birth. Due to its location, not as vascular so has to “tap in” to the deeper blood supply.
Classification depends on amount of coverage of cervical os (The internal os is the opening into the uterus from the cervix).
What are the risk factors involved in placenta previa?
- Previous C-sec
- Multiparity: won’t attach to previously used sites, or scars, causing it to move lower for a nutrient available spot.
- Smoking
- Infertility treatment
- AMA: advanced maternal age
When is placenta previa normally recognized?
Usu in the 2nd or 3rd trimester.
Occurs in 1/200 pregnancies.
Marginal, Partial, and Total are all classifications of what?
Degrees of the placenta previa.
Marginal: Placenta is implanted in the lower uterus but its lower border is greater than 3 cm from the internal cervical os.
Partial: Lower border of placenta is within 3 cm of internal cervical os but does not fully cover it.
Total: Placenta completely covers the internal cervical os.
Signs and Symptoms and how to Dx placenta previa:
- thin, bright red vaginal bleeding
- painless
- with or without contractions
- soft, non-tender abdomen
- fetal heart tones within normal limits
Dx:
Clinical exam, S and S
Ultra sound
Management of placenta previa include:
- Bedrest
- NPO: until out of danger of c-sec; stable
- Fetal monitoring
- NO sterile vag exams: may disrupt placenta
- Tocolytics: Tocolytics are medications used to suppress premature labor such as Terbutaline (controversial bc it’s a smooth muscle relaxant = increase the bleeding?)
- C-section
- Emotional support: scary, education on when to call provider, feel out of control…
- Hemorrhage risk: even after delivery they are still at higher risk for bleeding.
This occurs at greater than 20 weeks gestation, has a maternal mortality of 6% and a neonatal mortality at 33%:
What are some causes of this condition?
Placental Abruption. Fetal loss usually occurs before arrival at the hospital.
CAUSES:
- Maternal HTN
- Maternal trauma: Domestic violence, falls, car accident
- Smoking/ Alcohol/ Drug use
- Preeclampsia
- DM (DM and preeclampsia both have endothelial damange occuring = increased risk of placental disruption.
- Short umbilical cord: increased risk of it pulling away
- Decompression of uterus: rupture of membranes, delivery of first twin = the change of pressure.
- AMA
What are the three classifications of placental abruption based on?
Classifications are based on the amount of separation and whether bleeding is concealed or not…
Marginal, Partial, or Complete… external bleeding is visible, concealed is not.
We Dx concealed bleeding indirectly with:
- Assessment and ultrasound
- Signs of fetal distress
- Contractions have low amplitude and high frequency
- Uterus does not rest
Signs and Symptoms of Placental Abruption:
- With external bleeding: Dark red, thick
- UC pattern: uterine contraction pattern of strong, continuous, no resting tone.
- Rigid, tender abdomen
- Shock symptoms: d/t hypovolemia
- Fetal distress
What are 7 complications related to Placental Abruption?
- Hemorrhage
- Hypovolemia
- Hysterectomy
- Renal failure
- DIC
- Fetal death
- Risk of recurrence: in same pregnancy as well as subsequent pregnancies.
How is Placental Abruption managed?
- Obstetric emergency: call c-sec team to the unit STAT including all OR staff (surgeon, anesthesiologist).
- Side-lying position: to optimize perfusion
- O2: 10 L via non-rebreather face mask to hyper-oxygenate.
- Volume replacement: trying to get them hemodynamically stable whether by fluids or by blood. Need to type and cross pt to match for avail. blood products.
- Fetal monitoring: continuous
- C section, unless vaginal delivery is imminent.
- Emotional support: Scary. Try to be present for the patient and their family. Try to explain what’s happening and what WILL happen. Be aware of emotional needs after the patient is stable.
What is the gestation range defined by “preterm”?
20-37 weeks
March of Dimes goal is to raise awareness and help decrease prematurity.
What risk factors are there regarding PTL?
PreTerm Labor risk factors:
- Idiopathic 70-80% of cases. =(
- *Previous PT delivery
1 previous = 35% risk
2 previous = 70% risk - *Incompetent cervix (usually due to injury of cervix)
- Uterine anomalies: odd shapes or septums in the uterus.
- Infection: Cervical, Urinary, STIs
- Multiple gestation: the greater stretch, the more likely body will go in to labor… run out of room.
- Hydramnios: again, more stretch/strain on body
- Placenta previa/ abruption
- Tobacco/ Substance abuse
- Age/ Ethnicity: less than 18 or greater than 35/ African Americans have the highest rate.
