Computed tomographic imaging interpretation improves fetal outcomes after maternal trauma

Area of Science:

• Medical Imaging
• Obstetrics & Gynecology
• Trauma Surgery

Background:

• Computed tomography (CT) is validated for identifying and classifying placental abruption after blunt trauma.
• Placental abruption poses risks to both mother and fetus in trauma cases.
• Timely intervention is crucial for improving fetal outcomes.

Purpose of the Study:

• To assess if a protocol of immediate delivery improves fetal survival in pregnant trauma patients with placental abruption.
• To correlate CT findings of placental perfusion with fetal well-being and outcomes.
• To establish delivery protocols based on fetal heart rate tracings and abruption severity.

Main Methods:

• Retrospective review of pregnant trauma patients (≥26 weeks gestation) undergoing abdominopelvic CT.
• Classification of placental abruption based on CT-determined placental perfusion (Grade 1, 2, 3).
• Analysis of delivery indications, timing, and fetal outcomes, including Apgar scores.

Main Results:

• CT identified placental abruption in 15% of patients (6/41).
• All patients with Grade 2 or greater abruption developed concerning fetal heart tracings and underwent emergent delivery.
• All emergent deliveries resulted in viable births with favorable Apgar scores, indicating improved fetal outcomes.

Conclusions:

• Delivery protocols triggered by nonreassuring fetal heart rate tracings in the third trimester improve fetal outcomes in cases of significant placental abruption (Grade 2+).
• CT classification of placental abruption is a valuable tool in guiding management decisions.
• Early, protocol-driven delivery can significantly enhance fetal survival rates in pregnant trauma patients.
