O71.1 Rupture of uterus during labor

Name of the Condition

• Rupture of Uterus During Labor

Summary

Rupture of the uterus during labor is a serious obstetric complication where the uterine wall tears during the active stages of labor. This condition requires immediate medical intervention due to the risk of severe hemorrhage, maternal injury, and fetal harm. It is a rare but life-threatening event that demands prompt recognition and management.

Causes

Uterine rupture during labor typically occurs due to mechanical stress on the uterine wall, often from prior uterine surgery (e.g., cesarean delivery) or uterine overdistension (e.g., multiple gestation). Trauma from instrumental delivery, prolonged labor, or intense uterine contractions (e.g., from oxytocin) can also contribute. In some cases, congenital uterine abnormalities or weakened tissue may predispose to rupture.

Risk Factors

• Prior uterine surgery, including cesarean delivery or myomectomy.
• Multiple pregnancies or polyhydramnios.
• Prolonged or difficult labor.
• Use of oxytocin or other uterotonic agents.
• Advanced maternal age or multiparity.
• Congenital uterine anomalies (e.g., bicornuate uterus).

Symptoms

• Sudden, severe abdominal pain.
• Vaginal bleeding or hemorrhage.
• Fetal distress (e.g., abnormal heart rate).
• Signs of shock (e.g., hypotension, tachycardia).
• Abdominal tenderness or rigidity.
• Cessation of uterine contractions.

Diagnosis

Diagnosis is based on clinical presentation, including sudden pain, bleeding, and fetal distress, confirmed by ultrasound or physical examination. Imaging may be used to evaluate internal injuries or organ damage when clinically indicated. Prompt assessment is critical to guide immediate intervention.

Treatment Options

• Immediate surgical repair of the uterine rupture.
• Blood transfusion to manage hemorrhage.
• Delivery of the fetus, often via emergency cesarean section.
• Monitoring for maternal and fetal stability.
• Postoperative care to prevent infection and complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the rupture, timing of intervention, and maternal-fetal status. With prompt treatment, maternal survival is high, but fetal outcomes may vary. Follow-up includes monitoring for infection, uterine healing, and future pregnancy planning. Long-term care may involve obstetric and surgical consultations.

Complications

• Severe maternal hemorrhage.
• Fetal injury or death.
• Infection (e.g., endometritis).
• Hysterectomy (if uterine repair is not feasible).
• Long-term reproductive complications.

Lifestyle & Prevention

• Prenatal care to identify risk factors (e.g., prior uterine surgery).
• Avoidance of excessive uterotonic use without monitoring.
• Careful management of labor in high-risk pregnancies.
• Counseling on vaginal birth after cesarean (VBAC) risks.

When to Seek Professional Help

Seek immediate medical attention if sudden severe abdominal pain, vaginal bleeding, or fetal distress occurs during labor. Prompt evaluation is critical to prevent life-threatening complications.

Tips for Medical Coders

Document the timing of the rupture (during labor), clinical findings (e.g., pain, bleeding), and interventions (e.g., surgery, transfusion). Include details on prior uterine surgery or risk factors if relevant. Ensure documentation supports the diagnosis and aligns with clinical guidelines for accurate coding.
