Evaluation of hemoperitoneum using a single- vs multiple-view ultrasonographic examination

Area of Science:

• Emergency Medicine
• Radiology
• Trauma Surgery

Background:

• Rapid diagnosis of hemoperitoneum is critical in trauma patients.
• Ultrasound (US) is a valuable tool for initial trauma assessment.
• Standardized US protocols aim to improve diagnostic accuracy.

Purpose of the Study:

• To compare the diagnostic performance of single-view versus multiple-view ultrasonography (US) for hemoperitoneum detection.
• To evaluate sensitivities, specificities, and accuracies of different US techniques in trauma patients.
• To determine the optimal US approach for identifying intraperitoneal fluid in major trauma.

Main Methods:

• Retrospective analysis of a prospective trauma US database.
• Inclusion of adult patients with major blunt or penetrating torso trauma.
• Comparison of interpretations from single-view (Morison's pouch) and multiple-view US examinations against criterion standards (CT, DPL, laparotomy).

Main Results:

• Multiple-view US demonstrated 87% sensitivity, 100% specificity, and 98% accuracy.
• Single-view US (Morison's pouch only) showed 51% sensitivity, 100% specificity, and 93% accuracy.
• The multiple-view technique significantly improved sensitivity for detecting hemoperitoneum.

Conclusions:

• A multiple-view trauma US examination is more sensitive than a single-view technique for identifying hemoperitoneum.
• The findings support the use of comprehensive US protocols in trauma assessment.
• Enhanced sensitivity of multiple-view US can lead to more timely and appropriate patient management.
