Postpartum hematomas are localized blood collections that can form in the connective tissue beneath the skin or vaginal mucosa after childbirth, usually without laceration. They are caused by trauma during delivery or inadequate suturing. Symptoms include pain, discolored skin, and decreased blood pressure or lochia flow. Small hematomas are monitored but large ones may require evacuation. Complications can include infection, anemia, and prolonged recovery. Nurses monitor for signs, provide pain relief, and educate on diet, hygiene and recovery.
