Introduction. Extended focused assessment with sonography for trauma (E-FAST) can be performed with minimal training and achieve ideal results. It allows easy transport and use in austere environments such as the Colombian Caribbean, where many centers do not have 24-hour radiology services. The objective of this study was to determine the performance of the use of E-FAST in the evaluation of trauma by second-year general surgery residents in the emergency department.
Methods. Retrospective observational study that evaluated the diagnostic performance of E-FAST with Butterfly IQ, in patients with thoracoabdominal trauma, who attended a referral center in the Colombian Caribbean between November 2021 and July 2022. Sensitivity, specificity, and positive and negative predictive values were evaluated, compared with intraoperative findings or conventional imaging.
Results. A total of 46 patients were included, with a mean age of 31.2 ± 13.8 years, 87.4% (n=39) were male. The main mechanism of trauma was penetrating (n=32; 69.5%). It was found that 80.4% (n=37) of the patients had a positive E-FAST result, and of these, 97% (n=35) had a positive intraoperative finding. Sensitivity, specificity, positive predictive value and negative predictive value were 92.1%, 75%, 94.6%, and 66.6%, respectively. The positive likelihood ratio was 3.68, while the negative likelihood ratio was 0.10.
Conclusion. General surgery residents have the competence to perform accurate E-FAST scans. The hand-held ultrasound device is an effective diagnostic tool for trauma and acute care surgery patients.
