O71.2 Postpartum inversion of uterus

Name of the Condition

• Postpartum Inversion of Uterus

Summary

Postpartum inversion of the uterus is a rare but serious obstetric complication where the uterus turns inside out after delivery, often due to excessive traction on the umbilical cord or improper management of the placenta. This condition requires immediate medical intervention to prevent severe hemorrhage and maternal morbidity.

Causes

Postpartum uterine inversion typically occurs when excessive force is applied to the umbilical cord during delivery, such as pulling to expel the placenta, or when the placenta is manually removed without proper technique. It may also result from uterine atony (lack of muscle tone) or weak uterine ligaments, which can allow the uterus to invert spontaneously.

Risk Factors

• Manual removal of the placenta.
• Use of uterine stimulants (e.g., oxytocin) during delivery.
• Prolonged or difficult labor.
• Multiparity (previous pregnancies).
• Uterine atony or weak uterine ligaments.

Symptoms

• Severe abdominal pain or a feeling of "something coming out" of the vagina.
• Excessive vaginal bleeding or hemorrhage.
• Shock (e.g., hypotension, tachycardia).
• Palpable mass or tissue protruding from the vagina.
• Fainting or dizziness due to blood loss.

Diagnosis

Diagnosis is based on clinical observation of a protruding uterine tissue mass through the vagina or cervix, often confirmed by physical examination. Imaging (e.g., ultrasound) may be used to assess the extent of inversion or associated injuries when clinically indicated.

Treatment Options

• Immediate manual repositioning of the uterus under anesthesia to restore normal anatomy.
• Administration of uterine stimulants (e.g., oxytocin) to promote uterine contraction and prevent recurrence.
• Blood transfusion or fluid resuscitation to manage hemorrhage and shock.
• Surgical intervention if manual repositioning is unsuccessful or complications arise.

Prognosis and Follow-Up

With prompt treatment, most cases of uterine inversion resolve without long-term complications. Follow-up care includes monitoring for infection, assessing uterine tone, and ensuring proper healing. Future pregnancies may require careful management to prevent recurrence.

Complications

• Severe hemorrhage leading to shock.
• Infection (e.g., endometritis).
• Uterine atony or retained placental tissue.
• Damage to uterine or vaginal structures.
• Maternal mortality in severe, untreated cases.

Lifestyle & Prevention

• Avoid excessive cord traction during placental delivery.
• Use proper technique for manual placental removal.
• Monitor uterine tone and contraction status post-delivery.
• Educate healthcare providers on signs and management of uterine inversion.

When to Seek Professional Help

Seek immediate medical attention if there is severe abdominal pain, excessive bleeding, or a visible tissue mass after delivery. Prompt intervention is critical to prevent life-threatening complications.

Tips for Medical Coders

Document the clinical presentation, including the presence of a protruding uterine mass, hemorrhage, or shock, to support the diagnosis. Note any interventions (e.g., manual repositioning, surgery) and associated complications. Ensure documentation aligns with the clinical criteria for postpartum uterine inversion to justify the code.
