From the Guidelines
Polyhydramnios is typically defined as an amniotic fluid index (AFI) greater than 25 cm or a single deepest pocket (SDP) greater than 8 cm, and it is categorized based on severity, with levels including mild, moderate, and severe 1. The levels of polyhydramnios can be summarized as follows:
- Mild: AFI > 25 cm or MVP > 8 cm, but less than a specific threshold (exact values may vary)
- Moderate: AFI between 30-34.9 cm
- Severe: AFI ≥ 35 cm It is essential to note that these levels are based on the most recent evidence available, and management strategies may vary depending on the underlying cause, gestational age, and severity of the condition. Some key points to consider in the management of polyhydramnios include:
- Regular monitoring with ultrasounds every 3-4 weeks for mild cases
- More frequent monitoring (every 1-2 weeks) and consultation with maternal-fetal medicine specialists for moderate to severe cases
- Potential treatments, such as therapeutic amniocentesis or indomethacin, may be considered for severe symptomatic cases
- Investigation of the underlying cause, including maternal glucose testing and detailed fetal anatomical assessment
- Close monitoring for complications, such as preterm labor, placental abruption, and cord prolapse, particularly as the pregnancy approaches term 1.
