Clinical meaning
A vaginal or vulvar hematoma is a collection of blood within the soft tissues of the perineum, vagina, or vulva that develops when blood vessels are damaged during vaginal delivery. The blood accumulates in the loose connective tissue, producing visible or palpable swelling, severe pain disproportionate to the apparent injury, and discoloration. Hematomas may form even without visible lacerations when deeper vessels rupture beneath intact skin or mucosa. Predisposing factors include instrumental delivery (forceps or vacuum), episiotomy, prolonged second stage of labor, precipitous delivery, first vaginal delivery, and pre-existing coagulopathy. The nursing role focuses on vigilant postpartum monitoring, early recognition, comfort measures, and prompt reporting of findings to the healthcare team.
Exam relevance
Risk factors: - Instrumental delivery (forceps or vacuum extraction) -- mechanical trauma to deep perineal vessels during application and traction - Episiotomy, especially mediolateral type, which cuts through vascular tissue and may extend deeper than intended - Prolonged second stage of labor (pushing phase) causing sustained pressure on perineal vasculature - Precipitous delivery (rapid, uncontrolled delivery) causing sudden stretching and vessel rupture - Nulliparity (first vaginal delivery) -- untested perineal tissues are less elastic and more susceptible to injury - Macrosomia (large birth weight infant over 4,000 g) requiring greater perineal distension during delivery - Pre-existing coagulopathy or use of anticoagulant medications (heparin, enoxaparin) impairing hemostasis after vessel rupture
