NCLEX Review Guide: Vulvar Hematoma

Definition and Formation

• Vulvar hematoma is a collection of blood in the soft tissues of the vulva caused by rupture of blood vessels, typically occurring during the second stage of labor or immediately postpartum.
• Results from trauma to vulvar tissues during delivery, especially with precipitous labor, forceps delivery, or episiotomy.

High-Risk Factors

• Precipitous labor (less than 3 hours) increases risk due to rapid tissue stretching without adequate time for gradual dilation.
• Operative vaginal delivery with forceps or vacuum extraction causing tissue trauma and vessel rupture.
• Large fetal size (macrosomia) or prolonged second stage of labor creating excessive pressure on vulvar tissues.

Signs and Symptoms

• Severe, throbbing vulvar pain that is disproportionate to normal postpartum discomfort and worsens over time.
• Visible unilateral vulvar swelling with bluish-purple discoloration and asymmetry of the vulva.
• Difficulty sitting, walking, or urinating due to pressure and pain from the expanding hematoma.
• Signs of hypovolemic shock if bleeding is severe: tachycardia, hypotension, pallor, and decreased urine output.

Assessment Priorities

1. Perform immediate visual inspection of the vulva and perineum for asymmetry and discoloration
2. Assess vital signs for signs of hemorrhage and hypovolemic shock
3. Measure hematoma size and document location (unilateral vs bilateral)
4. Evaluate pain level using 0-10 scale and characteristics of pain
5. Monitor urinary output and ability to void spontaneously

Immediate Interventions

• Apply ice packs immediately for the first 24 hours to promote vasoconstriction and reduce further bleeding and swelling.
• Position client in side-lying or semi-Fowler's position to reduce pressure on the affected area and promote comfort.
• Administer prescribed analgesics, typically requiring stronger pain medication than routine postpartum pain management.
• Monitor vital signs every 15 minutes initially, then every 30 minutes until stable to detect signs of ongoing hemorrhage.

Ongoing Care Management

• Encourage frequent voiding or catheterize if unable to void due to pressure from hematoma on urethra.
• Provide sitz baths after 24-48 hours when ice therapy is discontinued to promote healing and comfort.
• Educate client about expected healing timeline and signs of complications requiring immediate medical attention.

Potential Complications

• Hypovolemic shock from continued bleeding, requiring immediate fluid resuscitation and possible blood transfusion.
• Infection of the hematoma site leading to abscess formation, especially if surgical drainage was required.
• Urinary retention due to pressure on the urethra from large hematomas affecting normal voiding patterns.

Critical Reporting Criteria

• Rapid expansion of hematoma size or development of new areas of swelling indicating ongoing bleeding.
• Vital sign changes: systolic BP <90 mmHg, heart rate >120 bpm, or signs of shock.
• Inability to void for more than 6-8 hours postpartum or decreased urine output <30 mL/hr.
• Temperature elevation >100.4°F (38°C) suggesting possible infection of the hematoma.

Commonly Confused Points

Self-Assessment Checklist

• ☐ Can I identify the classic signs of vulvar hematoma?
• ☐ Do I know the immediate nursing interventions for vulvar hematoma?
• ☐ Can I differentiate between small and large hematoma management?
• ☐ Do I understand when to notify the healthcare provider?
• ☐ Can I explain the difference between hematoma and normal postpartum changes?
