The PowersIneffective ContractionsUterine Dystocia -defined as difficult labor.

Hypotonic contractions – coordinated, infrequent, weak, brief, mildly painful.

Hypertonic contractions – uncoordinated and erratic in frequency, duration and intensity; Painful.

Interventions for Uterine DystociaHypotonic Uterus: results from overstretched

uterine muscle leading to a prolonged active phase.

Nursing Interventions:Position changes, ambulationEmptying bladderAmniotomyPitocin administrationHydrationTeaching/Support

Interventions for Uterine DystociaHypertonic Uterus: Contractions are painful

but ineffective resulting in prolonged latent phase.

Nursing Interventions:Bed restSedation or pain reliefPosition changesSupport/educateComfort measures: calm environment, music,

therapeutic touch, back rub, warm shower, imagery

Ineffective Pushing.If pushing is ineffective, correct the cause.

Incorrect techniquesFear of injuryMinimal or no urgeMaternal exhaustionRegion block Psychological unreadiness

Precipitous LaborLabor < 3 hours from onsetComplications:

Woman loss of coping ability Lacerations of cervix, vagina, perineum

Fetus Hypoxia Cerebral trauma Pnemothorax

Precipitous LaborMonica, a G1, P0 @ 39.4wks is admitted to L&D with

occasional uterine contractions that started soon after her BOW broke an hour ago. She pauses during conversation to breath during contractions and gives a pain rating of 5. Monica states she will probably want an epidural.

While performing the admission history/assessment you notice that Monica’s contractions are occurring every 2 minutes and palpate strong. Monica is beginning to demonstrate difficulty with coping during contractions. Monica grunts during her last contraction.

What nursing interventions will you provide?

Nursing Care in Dysfunctional Laborintrauterine infection

Identify s/sReduce risk

Assist with exhaustionConserve energyPromote coping skills

Premature Rupture of Membranes - PROMSpontaneous rupture of membranes prior to

the onset of laborAssociated conditions:

Preterm LaborDefined as: labor that occurs between 20 and

37 weeks gestation.Associated conditions

Multiple gestationHydraminosUTIAbdominal traumaInfectionNo prenatal careLow socio-economic status

Preterm LaborPrevention of PTL

Education Diagnosing PTL:

Fetal Fibronectin test (fFN) 99% accurate predictor of NO preterm birth within

7 days

Preterm LaborTocolytics: Tocolytics: Medications prescribed to stop preterm labor

Magnesium sulfate – CNS depressantNifedipine – Calcium channel blockerIndomethacin – Prostaglandin synthesis

inhibitorTerbutaline – B adrenergic receptor agonist

Tocolytic Drugs - Smooth Muscle Relaxants. Magnesium Sulfate Contraindications: discontinue for resp. depression, magnesium level >8, administer ca+ gluconate

Side Effects: flushing, headache, nausea, lethargy, dizziness, decreased DTR, decreased resp. rate, pulmonary edema

Nifedipine Contraindications: kidney or liver disease (especially cirrhosis), coronary artery disease, congestive heart failure, or digestive problems

Side Effects: flushing, headache, orthostatic hypotension, transient maternal/fetal tachycardia

Terbutaline Contraindications: hold and notify HCP if mat. HR > 120bpm

Side effects: increase heart rate, feeling of anxiety, headache, increased blood glucose

Indomethacin Contraindications: given X48-72 hoursSide effects: constriction of PDA, prolong bleeding, N/V, heartburn,

rash

Adherence to therapy

Prolapsed Umbilical CordOccurs when the umbilical cord precedes the

presenting part.Primary Risk Factor

Fetal head is not engaged or at a high station

Vessels carrying blood to & from the fetus are compressed, usually results in fetal distress or possible demise

Nursing InterventionsKnee chest positionAdminister O2Manual lift of fetal head off the cord

Ruptured UterusCauses:

Long difficult laborInjudicious use of PitocinPrevious C/S

Assessment FindingsFetal bradycardiaMaternal abdominal pain

Obstetrical TreatmentEmergency Cesarean Section delivery

Uterine Rupture

Anaphylactoid Syndrome: Amniotic Fluid Embolism

In the presence of a small tear in the amnion and chorion, a small amount of amniotic fluid may leak into the chorionic plate and enter the maternal blood system.

Can also occurs at areas of placental separation, cervical tears or during trumultuous labor

The more debris (meconium, vernix, lanugo) in the amnionic fluid, the greater the maternal problems caused by possible anaphylactic reaction to fetal antigens

Amniotic Fluid EmbolismAssessment Findings: Sudden onsetRespiratory distress (dyspnia)Circulatory collapse (cyanosis)TachycardiaHypotension Acute hemorrhageCor PulmonaleFrothy sputum

Amniotic Fluid EmbolismObstetrical EmergencyInterventions:

Large bore IV linePositive pressure oxygenCPRBlood transfusion - DICEmergency C/S if pregnant

Prognosis – 50% of women die with the first hour of symptoms

Amniotomy/Artificial Rupture of Membranes (AROM)

Advantages:Advantages:Increases frequency and intensity of uterine

contractionsRelease of prostaglandinsFacilitates decent of presenting partAllows for internal monitoringAbility to assess amniotic fluid

Disadvantages:Disadvantages:Increased risk for infectionPossibility of prolapsed umbilical cord

Artificial Rupture of Membranes

Amniotomy/Artificial Rupture of Membranes (AROM)Nursing careNursing care

Place disposable pads and towel under-buttock and change frequently

Assess FHR before and after amniotomyDocument: color, clarity, odor

Contraindication:Contraindication:**Procedure should not be performed if head is

not engaged**

Induction/Augmentation of LaborArtificial methods to stimulate uterine

contractions.Induction: Initiation of labor

Medical Elective

Augmentation: Improve quality of contractions

Bishop ScorePre-labor status evaluation scoring system

A predictor for the potential success of induction of labor

A high score indicates the cervix is favorable and vaginal delivery will likely occur

Pitocin (Oxytocin) AdministrationUses of Pitocin:Uses of Pitocin:Induction – initiates uterine contractionsAugmentation – enhances ineffective

contraction pattern

Goal:Goal:A labor pattern with uterine contractions occurring every 2-3 minutes, lasting 40-60 seconds and a return to baseline between contractions

Pitocin (Oxytocin) AdministrationNursing interventions when titrating Pitocin:

Maternal V/SFHR pattern

Baseline Variability Periodic changes
