Module 10 (Exam 3) Intrapartal Complications Flashcards
What are intrapartal complications?
- Dysfunctional Labor
- Precipitate Labor (fast)
- Preterm Labor
- Obstetrical Emergencies
Single Dysfunction
Causes:
- Irregular contraction pattern
- Ineffective Pushing
- Fetal size or position
- Maternal pelvic size or shape
Multifaceted Dysfunction (Dystocia)
- Prolonged Labor
- Combination of issues
- Depletion of resource (maternal fatigue, dehydration, energy stores)
- Maternal and/or fetal infection is a concern if membranes ruptured for greater than 24 hours
- Treat underlying causes
- Comfort measures and emotional support
- Monitor for infection
- C-section
- Precipitate Labor
- Birth occurs within 3 hours of onset
- No gradual change in contraction pattern
- May be associated with drug use (vasoconstrictor)
- Potential result: fetal oxygen compromise, precipate birth, newborn respiratory depression, postpartum hemorrhage
- Assist mother with breathing and relaxation
- Monitor fetal heart rate (rapid pelvic descent = variable decels or bradycardia)
- Call for help for patient room
- Don gloves
- Support infant’s head as it emerges onto perineum
- Encourage blowing or puffing to slow bearing down efforts but allow patient to bear down
Irregular Contraction PAttern
- Increase maternal movement (walk)
- Rest
- IV hydration
- Amniotomy (so then the head can act like a dilating wedge to open up the cervix)
- Augmentation with Pitocin
- Pain relief
- Emotional support
Ineffective Pushing
- Passive descent or “laboring down”
- Education regarding correct technique
- Emotional support
- Rest during some contractions
- Repositioning
- Feedback
Fetal Size or Position
- If fetal size is an issue = c-section
- If fetal position is an issue:
- (shoulder dystocia) McRoberts Maneuver, Suprapubic pressure
- C-section
Maternal Pelvic Size or Shape
- Maternal position change
- Maintain empty bladder
- C-section
PROM (premature rupture of membranes)
- Membranes rupture before the onset of labor
- Greater than 24 hours before birth occurs
PPROM (Preterm/Premature Rupture of membranes)
- Rupture of membranes happens before the end of the 37th week gestation
- Happens before the onset of labor (greater than 24 hours before birth of baby)
Etiology of PROM and PPROM
- Infection of maternal reproductive tract
- Incompetent cervix
- Polyhydraminos (puts pressure on cervix)
- Invasive tests or procedures
Effects of PROM
- Chorioamnionitis and newborn infection (ascending pathway for infection)
- Umbilical cord compression
Effects of PPROM
- Respiratory distress syndrome
- Complications related to prematurity
Medical management of PROM
- Maternal antibiotics
- Avoid vaginal examination
- Near term - induce labor
Medical management of PPROM
- Management determined by stability of fetus
- Assess lung maturity if 32-35 weeks
- Steroids
- Frequent nonstress test/biophysical profile
- Home management if stable
Nursing management or PROM or PPROM
- Labor inducted as indicated OR labor prevention
- Monitor FHR and contraction pattern if any
- Monitor for infection (VS q4h, WBC, amniotic fluid color, odor, clarity)
- Home care edcuation: activity restriction, signs/symptoms of labor and infection, importance of follow-up care
Preterm Labor
Onset of labor after 20 weeks but before 37 weeks’ gestation
Etiology and Risk Factors of Preterm Labor
- Etiology unknown
- Risk Factors:
- Short cervical length
- Previous preterm labor or PROM
- Positive fetal fibronectin
- Smoking
- Infection during pregnancy
- Smoking
- Infection during pregnancy
Signs/Symptoms of Preterm Labor
- Uterine contractions or “cramps”
- Back pain
- Pelvic pressure
- Bleeding or spotting
- Cervical effacement and/or dilation
Medical and Nursing Management of Preterm Labor
- Prevention
- Prenatal care
- Education (signs of labor)
- Identification of risk factors
- High risk group testing and monitoring
Treatment of Preterm Labor
- Treat underlying cause if possible
- Labor suppression by use of tocolytics
- Decrease activity
- Hydration (decrease uterine irritabiltiy)
- Steroids
- Home monitoring: decreased contraction pattern, no further cervical effacement and dilation
Tocolytics
- Magnesium sulfate
- High alert medication
- Smooth muscle relaxation
- IV
- Beta-adrenergic- Terbutaline
- Smooth muscle relaxation
- SQ, PO
- Prostaglandin Inhibitors - Indomethacin
- Decrease cervical effacement
- PO
- Calcium Channel Blockers - Nifedipine
- Inhibits contractions
- IV, PO
Nursing Considerations of Preterm Labor
- Education
- Medication Therapy
- Diagnostic tests/procedures
- Warning signs: similar to initial signs/symptoms of labor
- Infant milestones based on gestational age
Fetal Lung Maturity
- Corticosteriods
- Betamethasone/Dexamethasone
- Administered to mother for fetus
- Accelerates lung maturity
- Minimum of two spaced doses
- Anticipated birth less than 34 weeks OR Amniocentesis L/S less than 2:1 PG absent
What are some intrapartal emergencies?
- Placental Abruption
- Umbilical Cord Prolapse
- Uterine Rupture
Umbilical Cord Prolapse
- Fetal vertex not engaged
- Membranes rupture
- Umbilical cord slips toward fetal head
- Cord compressed by head
- Umbilical blood flow decreased to fetus
- May be occult or complete
Signs of Umbilical Cord Prolapse
- FHR change associated with ruptured membranes (occult prolapse)
- Protrusion of umbilical cord (complete prolapse)
Immediate Nursing Management of Umbilical Cord Prolapse
- Initial care for FHR pattern unless cord is visible
- Call for help
- Brief, calm explanations
If it is a confirmed prolapse or visible cord:
- Knee-chest or trendelenberg position
- Elevate fetal head with sterile gloved hand
- Anticipate emergency c-section
Classifications and Risk Factors of Uterine Rupture
Classifications: separation (dehiscence) at site of past uterine incision, complete rupture of uterus
Risk Factors: previous surgery, uterine overdistention, multiparity, pitocin induction/augmentation
Signs and Symptoms of Uterine Rupture
- Sudden onset
- Abdominal pain
- Hypovolemic shock
- Decreased BP, Elevated P, Change in LOC, Disphoresis
- FHR pattern change or loss of FHR (bradycardia)
Medical and Nursing Management of Uterine Rupture
- Prevention: monitor patients at risk, treat uterine tachysystole
- Treatment: initial supportive therapy (IV hydration, oxygne), emergent delivery, repair or removal of uterus
