Diagnostic value of a hand-carried ultrasound device for free intra-abdominal fluid and organ lacerations in major trauma patients
Emergency Medicine Journal, 04/25/2012
Schleder S et al. – In major trauma patients, examination with hand–carried ultrasound (HCU) according to the ‘focused assessment with sonography for trauma’ principles for the diagnosis of organ lacerations and free intra–abdominal fluid is a reliable and rapid alternative to multidetector CT (MDCT) scans and can help save precious time in emergency situations, and should, additionally, be evaluated in the pre–clinical workflow.
31 major trauma patients with an injury severity score >15 and the necessity of a MDCT scan (standard of reference) were enrolled prospectively to this study, and additionally examined with a HCU, according to ‘focused assessment with sonography for trauma’ principles for the assessment of organ lacerations and free intra-abdominal fluid.
The HCU device employed was of the latest generation.
Statistical analysis was performed using PASW V.18.
Four patients were diagnosed with free intra-abdominal fluid (prevalence 12.9%).
HCU showed a sensitivity and specificity of 75% and 100%, respectively.
Positive predictive value and negative predictive value were 100% and 96%, respectively.
Five patients had organ lacerations (prevalence 16.1%).
In these cases, the HCU was able to detect organ lacerations with a sensitivity and specificity of 80% and 100%, respectively.
Therefore, a positive predictive value and negative predictive value of 100% and 96%, respectively, were calculated.
