Peritoneal fluid refers to any abnormal fluid accumulation within the peritoneal cavity, the space surrounding abdominal organs, a critical finding in FAST (Focused Assessment with Sonography for Trauma) exams. This fluid, often blood (hemoperitoneum) due to blunt or penetrating trauma, appears anechoic or hypoechoic on ultrasound. Prompt identification is crucial for diagnosing internal bleeding and guiding immediate medical intervention, significantly impacting patient outcomes in emergency settings.
Early and accurate detection of peritoneal fluid via ultrasound is vital for trauma assessment, allowing clinicians to rapidly identify life-threatening injuries and initiate appropriate treatment strategies. This non-invasive imaging technique enhances decision-making in trauma centers, improving patient management and reducing morbidity and mortality associated with abdominal trauma.
