Week 4 Antepartum/pregnany Risks Flashcards
The many factors contributing to complications of the Antepartum period
Heart disease
High blood pressure
Diabetes
Kidney problems
Autoimmune diseases
Sexually transmitted diseases
Cancer
Trauma - Violence
Multiples
Life style issues (smoking, drinking, drugs, poor nutrition)
Placental or uterine issues
Preterm labor
Maternal age
Blood disorders
What is the most common complication seen in L&D?
Preterm Labor
Define late preterm labor
34-36.6 weeks
Define preterm
Anything before 33.6 weeks
Risk Factors for preterm Labor
Risk factors = 25%, 75% is unknown
Infections
Diabetes
Hypertension
multiple gestation
premature ROM
fetal conditions
poor prenatal care
drug or alcohol use
smoking
age of mother
Preterm labor drugs
•magnesium sulphate (IV; will slow down contractions in mom & neuro protection/brain bleed for baby)
•Betamethasone (surfactant/mature baby lungs!)
•procardia (PO; slow preterm contractions)
•indocin (PO; slow/control contractions)
•Terbutaline (Sub-Q; elevated HR, anxiety attack, but knocks contractions out!)
Procardia, indocin, terbutaline are heart meds. They may work to slow contractions but they also relax the heart!
Magnesium sulfate side effects
MgS04- Assess for respiratory depression, n/v, depression of CNS, low urine output, ALOC
Terbutaline side effects
Terbutaline- Non FDA approved. Causes rapid heart rate in both mother and fetus, dyspnea, cardiac arrhythmias, headache, anxiety and restlessness
Procardia side effects
Procardia - flushing, dizziness, HA, nausea tachycardia, mild hypotension, glucose levels raised
Indocin side effects
Indocin - use under 32 weeks, no longer than 48-72 hours. (If used over 32 weeks -risk of baby heart valves not closing and causes heart problems)
Cause Gl bleeds, epigastric pain, nausea, increased BP. Not for asthma or aspirin sensitive patients
Side effects on baby when using Tocolytics
Baby: constriction of ductus arteriosus, impaired renal function, decreased AFI > cord compression
Placenta previa
•Implantation and growth of the placenta over the vagina opening.
•classic sign: sudden onset of painless uterine bleeding
absolute indication for c-section
What do we do if vaginal bleeding is present (suspecting placenta previa)
•no vaginal exams
•no pitocin
•get ultrasound to see where placenta location is first
- vaginal exam could rupture placenta accidentally*
Placenta Abruption
“Premature separation of a normally implanted placenta”
•usually always a c-section (they’re bleeding internally)
•visible or sealed bleeding
•contractions will go crazy and start to freak baby heart rate out. They’re in distress
Etiology and risks for placenta abruption
Etiology: Unknown
Risk factors include:
-Maternal Hypertension* (#1)
-Cigarette smoking
-Short umbilical cord
-Abdominal trauma (MVA, assault)
-Previous history of placental abruption
-Maternal use of cocaine or amphetamines
Which can be prevented? Placenta previa or placenta abruption? How?
-Placenta previa cannot be controlled
-Placenta abruption can be prevented by Pt controlling BP, not smoking, not doing drugs (cocaine makes HR skyrocket)
Clinical manifestations for placenta Abruption
Classic Symptoms And Signs
-Vaginal bleeding
-Abdominal pain
-Uterine irritability or hypercontractile state
•Other Signs And Symptoms
-Back pain (especially with posterior placentas)
-Idiopathic preterm labor
-Fetal distress or fetal unrecognized fetal demise
-Coagulopathy or DIC
-Shock - hypovolemic or septic
Pregnancy induced HTN (PIH)
“A multi-organ disease process that develops in pregnancy & regresses in the postpartum period”
3 stages:
•1st & most common = Preeclampsia
A) mild
B) severe
•2nd = Eclampsia
•3rd = HELLP syndrome
What is considered Gestational HTN?
Gestational HTN = happens after 20 weeks
What puts patients into Preeclampsia?
•Mild: Proteinuria
•Severe: proteinuria & Critical BP (160/110)
What is the criteria moving from preeclampsia to eclampsia?
When the patient has a grand mal seizure
Preeclampsia signs
-Hypertension-sustained B/P 140/90 or
30mmHg systolic or 15 mmH diastolic from BL
-Generalized edema-legs, face and hands(fast weight gain)
-Proteinuria must be present to diagnose!
Tx for preeclampsia
- Home Care
-Activity restriction (Stay
stay off feet)
-Blood Pressure checks
-Fetal Surveillance (non-stress tests, ultrasounds, fetal kick counts)
Explain severe preeclampsia
B/P is 160/110 or higher (only 1 part of the BP needs to be high to have a problem)*
-Proteinuria is more than 500mg/day (3+ or >)
-Elevated liver enzymes (enlarged liver-AST/ALT)
-Oliguria occurs (500ml or < in 24 hrs.)
-Other S/S are usually present: headache, epigastric pain, visual disturbances (high BP)
Meds for severe preeclampsia
-Hospitalization, seizure prevention
-Antihypertensive meds: (IV PUSH; Apresoline, Labetalol)
-Anticonvulsant medications:(IV DRIP MgS04 do mag toxicity checks!)
-May have labor induced
-Postpartum assessments should be continued for at least 48 hrs. or until s/s show recovering.
