Nursing Care during the Third Stage of Labor
Key Points
- Third-stage care centers on placental delivery, uterine tone support, and hemorrhage prevention.
- Third stage typically lasts about 5 to 30 minutes, and delayed placental delivery increases risk.
- Placental delivery beyond 30 minutes increases risk for postpartum hemorrhage and manual extraction.
- Active management includes uterotonic use, structured assessment, and rapid response to abnormal bleeding.
Pathophysiology
The third stage starts after newborn birth and ends when the placenta is delivered. Ongoing uterine contraction decreases placental implantation surface and promotes placental separation; effective uterine tone then compresses vessels to reduce blood loss.
Failure of timely separation, retained tissue, or inadequate uterine contraction can cause severe postpartum bleeding. Nursing surveillance during this short but high-risk stage is therefore continuous and intervention-driven.
Classification
- Separation-progress domain: Hallmark signs include uterine shape change, blood gush, and cord lengthening.
- Hemorrhage-risk domain: Excessive blood loss, uterine atony, retained placenta, and laceration-associated bleeding.
- Medication domain: Prophylactic and therapeutic uterotonics.
- Recovery-support domain: Pain support, bonding facilitation, and calm environment maintenance.
Nursing Assessment
NCLEX Focus
Priority questions emphasize early recognition of hemorrhage and retained placenta during third-stage monitoring.
- Assess vital signs at least every 15 minutes in stable patients, watching for trend deterioration.
- Include blood pressure, pulse quality/rate, respiratory rate, and oxygen saturation in each third-stage vital-sign cycle; escalate rapidly for hypotension or rapid/weak pulse patterns.
- Trend maternal temperature about every hour during third-stage surveillance.
- Monitor fundal height, firmness, and tone while tracking vaginal bleeding amount and character.
- Prefer quantitative blood-loss tracking over visual estimation and escalate promptly for cumulative loss above expected range or any symptomatic instability.
- Identify placental separation signs and time from birth to placental expulsion.
- If placenta is undelivered at 30 minutes, escalate retained-placenta pathway and anticipate manual/procedural management planning.
- After placental delivery, verify completeness with provider assessment because retained fragments/cotyledons can sustain hemorrhage and infection risk.
- Assess bladder distention, pain, and perineal status for contributors to poor uterine contraction or hidden bleeding.
- Confirm placental-separation cues such as cord lengthening, uterine shape change, cramping, and increased vaginal bleeding before/around expulsion.
- Treat severe pelvic pain with hemorrhage and absent fundus as possible uterine inversion and escalate emergently.
- During third-stage overlap with immediate newborn care, verify neonatal transition checks (for example Apgar at 1 and 5 minutes, early temperature, and risk-based pulse/respiratory reassessment cadence).
Nursing Interventions
- Administer ordered uterotonic prophylaxis promptly (commonly oxytocin) after birth/placental delivery.
- Support placental delivery and provider procedures with sterile setup and focused communication.
- During delayed but nonemergent placental delivery management, assist provider-directed controlled cord traction with uterine counterpressure when indicated.
- If spontaneous placental expulsion does not occur and manual extraction is required, increase surveillance for infection and hemorrhage risk.
- After placental expulsion, perform or assist protocol-based uterine massage/firmness checks to support vessel constriction and early atony detection.
- Quantify blood loss whenever possible and escalate immediately for heavy or worsening bleeding.
- Support immediate newborn thermoregulation during third-stage overlap (drying, warm blankets, head covering, and skin-to-skin when feasible).
- Promote skin-to-skin and early feeding efforts to support endogenous oxytocin and bonding.
- Use a calm, low-stimulation environment with reassurance and guided breathing to reduce distress and support third-stage rest/recovery.
- Support delayed cord clamping for about 30 to 60 seconds when newborn status is stable; if compromise is present, prioritize warmer transfer and neonatal stabilization.
Hemorrhage Emergency Window
Rapid increase in bleeding, hypotension, tachycardia, or poor uterine tone signals potential postpartum hemorrhage requiring urgent team response.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| uterotonics | Oxytocin, misoprostol, methylergonovine, carboprost | First-line prevention/treatment of uterine atony-related bleeding during third stage. |
| antifibrinolytics | Tranexamic acid context | Supports clot stability in hemorrhage pathways when ordered. |
Clinical Judgment Application
Clinical Scenario
Ten minutes after birth, placental separation is incomplete and bleeding increases while uterine tone becomes less firm.
- Recognize Cues: Delayed placental progress, rising blood loss, and reduced uterine firmness.
- Analyze Cues: Third-stage physiology may be shifting toward atony/retained tissue risk.
- Prioritize Hypotheses: Immediate risk is progression to postpartum hemorrhage.
- Generate Solutions: Intensify fundal assessment, quantify blood loss, administer ordered uterotonic measures, and escalate.
- Take Action: Activate hemorrhage-oriented communication and intervention workflow.
- Evaluate Outcomes: Placenta is delivered, uterus remains firm, and bleeding trend stabilizes.
