Normal labor is characterized by progress. Dystocia is a general term that applies to any difficult labor or birth. Causes › The Powers › The Passenger › The Passageway › The Psyche
Ineffective uterine contractions › Uterine Dystocia Hypertonic Contractions Hypotonic Contractions Ineffective Maternal Pushing
Hypotonic contractions › Weak › Infrequent › Short › Pt comfortable Nursing interventions › Walking › Position changes › Amniotomy › Oxytocin
Hypertonic Contractions › Uncoordinated and eratic › Painful but ineffective › Usually occurs in latent phase › High resting tone › Maternal fatigue Nursing interventions › Pain management › Promote relaxation › Analgesics › Oxytocin or amniotomy › Tocolytics may be ordered
Incorrect technique Fear Decreased urge Exhaustion
Fetal Size Malpositions Malpresentations Multifetal pregnancy Fetal Anomalies
Vacuum extraction Forcep delivery › Risks of both to the baby › Risks of both to the mother
Pelvis › Pelvic Dystocia (Cephalopelvic Disproportion) Bladder Interventions
Monica, a G1, 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?
Pain Stress Fear Support
Prolonged Labor › Once in active phase should proceed at 1-2 cm/hr › Risk Factors › Nursing interventions Precipitous Labor › Birth that occurs within 3 hours of the onset of labor › Causes › Nursing interventions
Spontaneous rupture of membranes prior to the onset of labor Associated conditions: › Infection STDs, UTI, GBS › Previous history of PROM › Amniotic sac with a weak structure › Fetal abnormalities › Overdistention of the urterus › Maternal stress › Trauma
Determine time of PROM Verification of PROM: Visualization Sterile speculum exam for ferning pH
Nursing Assessment › Vital signs (temp q 2hr) › Fetal monitoring › Nature of fluid › WBC count Administration of Celestone - betamethasone › PROM: preterm If leak seals, discharge instructions
Defined as: labor that occurs between 20 and 37 weeks gestation. Associated conditions › Multiple gestation › Hydraminos › UTI › Abdominal trauma › Infection › No prenatal care › Low socio-economic status
Cervical Length Fetal Fibronectin test › 99% accurate predictor of NO preterm birth within 7 day Infections
Treat the underlying cause › Preeclampsia › Hypovolemia › Serious Infection Promote rest Hydration
Tocolytics Medications prescribed to stop preterm labor › Terbutaline – B adrenergic receptor agonist › Indomethacin- Prostaglandin inhibitor › Magnesium sulfate – CNS depressant › Nifedipine - Calcium channel blocker
Necessary if infant < 34 weeks (24-34 weeks) Betamethasone › Every 7 days › Birth should be delayed by 24 hours
Occurs 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 Interventions › Knee chest position › Administer O2 › Manual lift of fetal head off the cord
Causes: › Long difficult labor › Injudicious use of Pitocin › Dehisence › High parity › Blunt abdominal trauma
Pain Chest pain Hypovolemic shock Impaired fetal oxygenation Absent fetal heart sounds Cessation of uterine contractions Palpation of fetus
Identify the risks Use oxytocin cautiously Monitor bleeding
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
Assessment Findings: Sudden onset Respiratory distress (dyspnea) Circulatory collapse (cyanosis) › First the right ventricle, then left Tachycardia Hypotension Acute hemorrhage › DIC
Obstetrical Emergency Interventions: › CPR › Mechanical ventilation › Correction of hypotension › Blood transfusion - DIC › Emergency C/S if pregnant Prognosis – 50% of women die with the first hour of symptoms
