Objective To evaluate the accuracy of tracheal ultrasonography for confirming the endotracheal tube placement during patients’ intubation. Patients and methods The current study was a prospective, randomized study performed at the ICU of Al-Hussein Hospital, Cairo. Intubated for respiratory failure, cardiac arrest or other medical causes were included in the current study. Real-time tracheal ultrasonography was conducted during intubation with the ultrasound probe placed transversely over the trachea above the suprasternal notch for confirming the tube position, either tracheal or esophageal. The standard method for confirming endotracheal tube placement include clinical evaluation and rapid bronchoscopic confirmation. The main outcomes were the degree of accuracy and timeliness of tracheal ultrasound in confirming endotracheal tube placement. Results Forty patients eligible for endotracheal intubation were randomized in the current study and only four (10%) patients had confirmed esophageal intubations. Our results concluded that tracheal ultrasound had a diagnostic accuracy of 97.5% in the detection of endotracheal tube site. The sensitivity was 97.2%, while the specificity was 100%. Tracheal ultrasound had a positive predictive value of 100%, while the negative predictive value was 80%. The total operating time of ultrasonography was significantly lower than that of bronchoscopy. Conclusion Real-time ultrasound of the trachea is an accurate, feasible, and fast method in confirming endotracheal tube placement.
