Study Notes
Induction of Labor
- The goal of induction of labor is to initiate labor before it begins naturally.
- Oxytocin (Pitocin) is used to induce labor, with a goal of achieving effective contractions every 2-3 minutes, lasting 40-90 seconds, and with an intensity of 50-80 mmHg.
- Oxytocin stimulates smooth muscle contraction, triggers contractions in uterine smooth muscle, and promotes milk letdown in lactating women.
Oxytocin Side Effects
- Hypotension
- Hypertension
- Dysrhythmias
- Headache
- Anorexia
- Nausea and Vomiting
Oxytocin Nursing Implications
- Oxytocin is administered via secondary IV with a TWO nurse check required.
- Determine fetal maturity, presentation, and pelvic adequacy prior to administration.
- Assess frequency, duration, intimacy, and resting tone of contractions.
- Continuous EFM is required, and oxytocin should be stopped in the event of fetal distress or hyperstimulation.
Preterm Labor
- Regular contractions that result in cervical dilation after 20 weeks gestation but prior to 37 weeks gestation.
- Goal of tocolytic therapy is to decrease or stop uterine contractions and allow the fetus to mature.
- Corticosteroids are used to increase fetal lung maturity.
Tocolytics
- Magnesium sulfate
- Calcium Channel Blockers (Nifedipine)
- Prostaglandin Synthesis Inhibitors (Indomethacin)
- Beta-Adrenergics (Terbutaline)
Magnesium Sulfate
- Used to stop preterm labor via tocolysis.
- Mechanism of action: inhibits synthesis of prostaglandins that stimulate smooth muscle contraction.
- Side effects: maternal nausea, vomiting, heartburn, prolonged bleeding time, fetal constriction of PDA, and oligohydramnios.
Calcium Channel Blockers (Nifedipine)
- Used to stop preterm labor via tocolysis.
- Mechanism of action: blocks Ca entry into smooth muscle cells, decreasing rate and force of contractions.
- Side effects: orthostatic hypotension, headache, dizziness, flushing, and fluid retention.
Prostaglandin Synthesis Inhibitors (Indomethacin)
- Used to stop preterm labor via tocolysis.
- Mechanism of action: inhibits synthesis of prostaglandins that stimulate smooth muscle contraction.
- Side effects: maternal nausea, vomiting, heartburn, prolonged bleeding time, fetal constriction of PDA, and oligohydramnios.
Beta-Adrenergics (Terbutaline)
- Used to stop preterm labor via tocolysis.
- Mechanism of action: smooth muscle relaxant, producing bronchodilation and uterine relaxation.
- Side effects: tachycardia, cardiac dysrhythmias, chest pain, dyspnea, hyperglycemia.
Cardiac Disease in Pregnancy
- Goal of anticoagulant therapy: prevent undesired clotting.
- Goal of diuretic therapy: control CHF manifestations.
- Goal of antidysrhythmic therapy: control cardiac dysrhythmias.
Anticoagulants
- Prevent undesired clotting.
- Heparin is used to prevent stroke, MI, and death.
Heparin
- Used to prevent undesired clotting.
- Mechanism of action: prevents clot extension and formation.
- Contraindicated in pregnancy due to teratogenic effects on fetus!
Hypertensive Disorders in Pregnancy
- Chronic hypertension: diagnosed prior to 20 weeks gestation or after 12 weeks postpartum.
- Gestational hypertension: blood pressure that exceeds 140/90 mmHg diagnosed after 20 weeks gestation.
- Preeclampsia: blood pressure that exceeds 140/90 mmHg accompanied by proteinuria or other organ involvement.
- Eclampsia: progression of preeclampsia into generalized seizures.
Antihypertensives
- Vasodilators (Hydralazine): increase cardiac output and blood flow to placenta.
- Beta Blockers (Labetalol): reduce heart rate and vasoconstriction.
- Calcium Channel Blockers (Nifedipine): smooth muscle relaxation.
Magnesium Sulfate
- Used to decrease incidence and severity of seizures associated with eclampsia.
- Mechanism of action: decreases acetylcholine released by motor nerve impulses, blocks neuromuscular transmission, and depresses CNS.
- Side effects: depressed CNS, depressed deep tendon reflexes, depressed respirations.
Diabetes Mellitus in Pregnancy
- Pre-gestational diabetes: patient education focuses on insulin needs, diet, exercise, and medication regimen.
- Insulin needs decrease in the first trimester due to anti-insulin placental hormones and fetal consumption of glucose.
- Insulin needs increase in the second and third trimesters due to maternal insulin resistance.
- Euglycemia is key during labor and delivery to prevent neonatal hypoglycemia.
Patient Education
- Review signs of hypoglycemia and hyperglycemia.
- Review treatment of hypoglycemic episodes.
- Review correct procedure for glucose monitoring.
- Encourage appropriate diet, exercise, and medication regimen.
- Review proper insulin administration.
