4. Pharmacological (may require “informed consent”; follow hospital protocol). Betaadrenergic agents, MgSO₄ (take ECG first) to reduce sensitivity of uterine myometrium to oxytocic and prostaglandin stimulation; increase blood flow to uterus.
5. May be maintained at home with adequate follow-up and health teaching.

5. Contraindications for suppression: Labor is not suppressed in presence of:
   1. Placenta previa or abruptio placentae with hemorrhage.
   2. Chorioamnionitis.
   3. Erythroblastosis fetalis.
   4. Severe preeclampsia.
   5. Severe diabetes (e.g., “brittle”).
   6. Increasing placental insufficiency.
   7. Progressive cervical dilatation of 4 cm or more.
   8. Ruptured membranes (with maternal fever).
6. Assessment:
   1. Maternal vital signs. Response to medication:
      1. Hypotension.
      2. Tachycardia, arrhythmia.
      3. Dyspnea, chest pain.
      4. Nausea and vomiting.
   2. Signs of infection:
      1. Increased temperature.
      2. Tachycardia.
      3. Diaphoresis.
      4. Malaise.
      5. Increased baseline fetal heart rate; variability
   3. Contractions: frequency, duration, strength.
   4. Emotional status - signs of denial, guilt, anxiety, exhaustion.
   5. Signs of continuing and progressing labor. Note: Vaginal examination only if indicated by other signs of continuing labor progress.
      1. Effacement.
      2. Dilation.
      3. Station.
   6. Status of membranes.
   7. Fetal heart rate, activity (continuous monitoring).
7. Analysis/nursing diagnosis:
   1. Anxiety/fear related to possible outcome.
   2. Self-esteem disturbance related to feelings of guilt, failure.
   3. Impaired physical mobility related to imposed bed rest.
   4. Knowledge deficit related to medication side effects.
   5. Ineffective individual coping related to possible outcome.
   6. Impaired gas exchange related to side effects of medication (circulatory overload; pulmonary edema).
   7. Diversional activity deficit related to imposed bed rest, decreased environmental stimuli.
   8. Altered urinary elimination related to bed rest.
   9. Constipation related to bed rest.
8. Nursing care plan/implementation:
   1. Goal: inhibit uterine activity. Administer medications as ordered - terbutaline, magnesium sulfate, Procardia, Indocin.
   2. Goal: safeguard status.
      1. Continuous maternal/fetal monitoring.
      2. I&O - to identify early signs of possible circulatory overload.
      3. Position: side-lying - to increase placental perfusion, prevent supine hypotension.
      4. Report promptly to physician:
         1. Maternal pulse of 110 or more.
         2. Diastolic pressure of 60 mm Hg or less.
         3. Respirations of 24 or more; crackles (rales).
         4. Complaint of dyspnea.
         5. Contractions: increasing frequency, strength, duration, or cessation of contractions.
         6. Intermittent back and thigh pain.
         7. Rupture of membranes.
         8. Vaginal bleeding.
         9. Fetal distress.
   3. Goal: comfort measures.
      1. Basic hygienic care - bath, mouth care, cold washcloth to face, perineal care.
      2. Back rub, linen change - to promote relaxation.
   4. Goal: emotional support.
      1. Encourage verbalization of guilt feelings, anxiety, fear, concerns; provide factual information.
      2. Support positive self-concept.
      3. Keep informed of progress.
   5. Goal: provide quiet diversion. Television, reading materials, handcrafts.
   6. Goal: health teaching
      1. Explain, discuss proposed management to suppress preterm labor.
      2. Describe, discuss side effects of medication.
      3. Explain rationale for bed rest, position.

1. If labor continues to progress:
   1. Goal: facilitate infant survival.
      1. Administer betamethasone, as ordered, 24 - 48 hours before birth—to increase/stimulate production of pulmonary surfactant.
      2. Give antibiotic to mother to lower down chance of neonatal sepsis.
      3. Notify neonatal ICU (NICU) - to increase chances for fetal survival, ensure prompt, expert management of neonate, and provide information and support to parents.
      4. Monitor progress of labor to identify signs of impending birth. Note: May give birth before complete (10 cm) dilation.
      5. Consider transfer to high-risk facility.
      6. Prepare for birth, or cesarean birth if infant less than 34-36 weeks of gestation.
   2. Goal: emotional support.
