Free pelvic fluid

Free pelvic fluid, in the context of FAST/Trauma ultrasound, refers to any abnormal fluid collection detected within the pelvic cavity. This critical finding often indicates internal bleeding (hemoperitoneum) or other fluid effusions following blunt or penetrating trauma. Rapid identification of free pelvic fluid during a FAST exam is crucial for immediate patient management, guiding decisions on further diagnostic imaging or surgical intervention.

Its presence on ultrasound appears anechoic or hypoechoic, depending on the fluid’s composition (e.g., blood vs. urine). Prompt and accurate detection of free pelvic fluid through medical ultrasound significantly aids in triaging trauma patients and improving outcomes. Sonographers carefully assess the cul-de-sac and bladder views for subtle fluid accumulation.
