THE SENSITIVITY, SPECIFICITY AND ACCURACY OF STATIC METHOD OF ULTRASONOGRAPHY TO CONFIRM ENDOTRACHEAL INTUBATION IN EMERGENCY DEPARTMENT.

Abstract

Aims and objectives: This study aims to assess the diagnostic accuracy and timeliness of ultrasonography by static method only for identication of Endotracheal tube (ET Tube) placement in the trachea in emergency settings vs existing clinical methods. Material and Methods: This prospective study was carried out in the emergency room from October 2018 till the end of March 2019. The ultrasonography was performed in 120 emergency patients only after the intubation had been completed ie, static phase. A linear probe was used over the neck to identify the predened signs of ET intubation. Residents who perform ultrasound examination ll a form after assessment of each patient. Results: It was found that Tracheal Intubation-USG Sensitivity was 99.1, Specicity was 91.7, Positive Predictive Value: 99.1, Negative Predictive Value was 91.7 and Accuracy was 98.3%. Ultrasonography can be used as an adjunct tool to verify the ETTposition by Emergency Physicians which can be performed easily after a brieng or short-course training.Conclusion:This study demonstrates that US imaging has a high diagnostic accuracy to immediately conrm proper ETT placement post-intubation in an emergency setup. Therefore, it seems that ultrasonography using a static technique only is a proper screening tool in determining endotracheal tube placement.
