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\uf001cation\nof Endotracheal tube (ET Tube) placement in the trachea in emergency settings vs existing clinical methods. Material and Methods: This\nprospective study was carried out in the emergency room from October 2018 till the end of March 2019. The ultrasonography was performed in 120\nemergency patients only after the intubation had been completed ie, static phase. A linear probe was used over the neck to identify the prede\uf001ned\nsigns of ET intubation. Residents who perform ultrasound examination \uf001ll a form after assessment of each patient. Results: It was found that\nTracheal Intubation-USG Sensitivity was 99.1, Speci\uf001city was 91.7, Positive Predictive Value: 99.1, Negative Predictive Value was 91.7 and\nAccuracy was 98.3%. Ultrasonography can be used as an adjunct tool to verify the ETTposition by Emergency Physicians which can be performed\neasily after a brie\uf001ng or short-course training.Conclusion:This study demonstrates that US imaging has a high diagnostic accuracy to immediately\ncon\uf001rm proper ETT placement post-intubation in an emergency setup. Therefore, it seems that ultrasonography using a static technique only is a\nproper screening tool in determining endotracheal tube placement.
