Background and purpose: Shock detection techniques have been used on the basis of ultrasound technology. This study was thus conducted to investigate accuracy of RUSH in early recognition of emergency department patients.
Materials and Methods: During April 2016 to May 2017, we have recorded all the patients with shock at the emergency department of Shahid Mohammadi hospital and the samples were selected by simple sampling method. Shock was classified into 4 groups: hypovolemic, cardiogenic, distributive and obstructive. The Kappa index was used for final diagnosis.
Results: The data for hypovolemic shock showed good sensitivity, excellent agreement, specificity and accuracy and highest agreement with final diagnoses were observed for this shock. Good sensitivity, excellent specificity, accuracy and agreement were observed for cardiogenic shock. The data for obstructive shock showed good sensitivity and agreement, excellent specificity and accuracy. Moreover, low agreement, excellent specificity, sensitivity and accuracy were seen in distributive shock.
Conclusion: These results provided reliable information for clinicians to make a fast and acceptably accurate recognition of the shock type in a hypotensive patient, especially for obstructive, cardiogenic or hypovolemic shock types.
