abstract

background focused assessment with sonography for trauma (fast) is a precise, non-invasive, and low cost method to assess free abdominal fluid in trauma patients. objective this study assessed the relationship between free intra-abdominal fluid and organ injury in blunt abdominal trauma and designed a scoring system based on fast. patients and methods a total of 200 patients with blunt abdominal trauma who had stable vital signs were assessed. for all patients, fast sonography was done by one sonographer and the free fluid score in the abdomen, which was in the range of 0-8, was calculated. immediately, an intravenous contrast-enhanced ct was performed in all patients and abdominal solid organ injuries were assessed. results were analyzed using the kruskal-wallis test, the mann-whitney test, and roc curves. results the mean age of the patients was 29.6 ± 18.3. in 71% of patients, trauma injury was due to car accidents. fast was negative in 33% of subjects. considering the cut-off point of 3, sensitivity, specificity, positive predictive value, and negative predictive value were calculated to be 0.83, 0.98, 0.93, and 0.95, respectively. comparing the mean scores from fast and ct-scan results showed that there is a correlation between the severities of organ injury and fast scores (p < 0.001). conclusion it was found that the amount of the intra-abdominal free fluid measured by fast is associated with solid abdominal organ injury in patients with blunt trauma.

correlation between intra-abdominal free fluid and solid organ injury in blunt abdominal trauma

conclusions it seems that fast examination for intra-abdominal fluid in blunt trauma patients can predict intra-abdominal injuries with very high sensitivity and specificity. using the scoring system can more accurately determine the probability of the presence of abdominal injuries with a cut-off point of three. results the mean age of the patients was 29.6 ± 18.3 years and fast was positive i...

Correlation Between Intra-Abdominal Free Fluid and Solid Organ Injury in Blunt Abdominal Trauma

BACKGROUND In previous studies, the diagnostic value of Focused Assessment with Sonography for Trauma (FAST) has been evaluated but few studies have been performed on the relationship between the amount of free intra-abdominal fluid and organ injury in blunt abdominal trauma. To select patients with a higher probability of intra-abdominal injuries, several scoring systems have been proposed bas...

The Utility of Ultrasound and Laboratory Data for Predicting Intra-abdominal Injury among Children with Blunt Abdominal Trauma

Background: Children with blunt abdominal trauma (BAT) can be risk stratified for intra-abdominal injury (IAI) through a combination of readily accessible clinical variables. The aim of this study was to identify ultrasound and laboratory studies that accurately identify IAI while limiting unnecessary CT-scan among children without injury. Materials and Methods We conducted a prospective, obse...

Correlating abdominal pain and intra-abdominal injury in patients with blunt abdominal trauma

background A thorough history and physical examination in patients with blunt abdominal trauma (BAT) is important to safely exclude clinically significant intra-abdominal injury (IAI). We seek to evaluate a correlation between self-reported abdominal pain, abdominal tenderness on examination and IAI discovered on CT or during exploratory laparotomy. Methods This retrospective analysis assessed ...
