“…16 A final study was excluded due to the lack of information regarding further clinical course, any confirmatory imaging to assess accuracy of the ultrasound to determine true/false negatives and positives. 17 Five studies were selected in the final meta-analysis with a total of 4263 patients ( Figure 1, Table 1). Among ultrasounds performed on the 4263 patients, 400 yielded positive and 3863 yielded negative FASTs.…”

Focused assessment with sonography for trauma (FAST) has been incorporated into the initial evaluation of trauma for decades. It is an important screening tool in the detection of intra-abdominal fluid. The objective of this study was to perform a systematic review of the use and accuracy of FAST as an imaging tool for blunt abdominal trauma in disaster/mass casualty settings. A systematic review of literature was conducted using key words and search terms. Two independent reviewers screened abstracts to determine inclusion using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS). For studies passing QUADAS, a meta-analysis was performed calculating sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). FAST results were compared with the gold standard, which was a combination of CT scan results, operative findings, and medical records of the clinical course. Initial database screening resulted in 133 articles, of which 21 were selected for QUADAS evaluation. Five studies passed QUADAS and were selected in the final meta-analysis, with a total of 4263 patients. The sensitivity of FAST was 92.1% (87.8–95.6), specificity 98.7% (96.0–99.9), PPV 90.7% (70.0–98.0), and NPV 98.8% (98.1–99.5) for the detection of intra-abdominal injury. In our meta-analysis, FAST was both sensitive and specific in the evaluation of trauma in the disaster setting.

“…For example, US showed good concordance with intraoperative findings in earthquake survivors with PNI. 7,8 The purpose of this case series of combatrelated PNI is to illustrate the utility of US imaging in the preoperative assessment of peripheral nerve injuries; US provided precise localization and severity data when other modalities could not.…”

“…Direct injury, ischemia/reperfusion injury, or compartment syndrome due to primary compression and secondary muscle swelling can lead to nerve injuries[138]. An acute increase in crushing can lead to muscle necrosis, compartment syndrome, swelling of the involved limbs, intense pain, diminishing sensation and muscle strength, and even paralysis[3940].…”

Published data on earthquake-associated peripheral nerve injury is very limited. Ultrasonography has been proven to be efficient in the clinic to diagnose peripheral nerve injury. The aim of this study was to assess the role of ultrasound in the evaluation of persistent peripheral nerve injuries 1 year after the Wenchuan earthquake. Thirty-four patients with persistent clinical symptoms and neurologic signs of impaired nerve function were evaluated with sonography prior to surgical repair. Among 34 patients, ultrasonography showed that 48 peripheral nerves were entrapped, and 11 peripheral nerves were disrupted. There was one case of misdiagnosis on ultrasonography. The concordance rate of ultrasonographic findings with those of surgical findings was 98%. A total of 48 involved nerves underwent neurolysis and the symptoms resolved. Only five nerves had scar tissue entrapment. Preoperative and postoperative clinical and ultrasonographic results were concordant, which verified that ultrasonography is useful for preoperative diagnosis and postoperative evaluation of injured peripheral nerves.
