O60 Preterm labor

Name of the Condition

• Preterm Labor

Summary

Preterm labor is the onset of regular uterine contractions and cervical changes before 37 weeks of gestation, potentially leading to preterm birth. It requires prompt evaluation to assess the risk of delivery and guide management.

Causes

The exact cause of preterm labor is often unknown but may involve factors such as infections, uterine overdistension, or placental abnormalities. Hormonal changes, stress, or trauma can also contribute to its onset.

Risk Factors

• Previous preterm birth
• Multiple gestation (e.g., twins)
• Uterine or cervical abnormalities
• Chronic conditions (e.g., hypertension, diabetes)
• Substance use (e.g., smoking, alcohol)
• Poor prenatal care

Symptoms

• Regular contractions (e.g., 4+ per 20 minutes)
• Pelvic pressure or cramping
• Vaginal bleeding or discharge
• Low back pain
• Cervical dilation or effacement

Diagnosis

Diagnosis involves assessing uterine activity, cervical changes, and fetal status. Tools may include fetal monitoring, cervical length measurement via ultrasound, and testing for fetal fibronectin in vaginal secretions.

Treatment Options

• Tocolytics to delay labor (e.g., for 48 hours)
• Corticosteroids to enhance fetal lung maturity
• Antibiotics for infections
• Magnesium sulfate for neuroprotection
• Bed rest or activity restriction

Prognosis and Follow-Up

Outcomes depend on gestational age at onset and response to treatment. Close monitoring is essential to manage complications and plan for delivery if labor progresses.

Complications

• Preterm birth
• Respiratory distress in the newborn
• Long-term developmental issues
• Maternal infection or hemorrhage

Lifestyle & Prevention

• Attend regular prenatal visits
• Manage chronic conditions
• Avoid smoking and substance use
• Maintain a healthy weight
• Seek prompt care for symptoms

When to Seek Professional Help

Contact a healthcare provider immediately for regular contractions, vaginal bleeding, or fluid leakage before 37 weeks.

Tips for Medical Coders

Code O60 is used for preterm labor. Documentation should specify the gestational age, presence of cervical changes, and any interventions. Ensure clear differentiation from other obstetric conditions.
