Abstract
Background: Intubation and maintaining airway are crucial in the management of critically ill patients in the emergency department. Correct tracheal intubation should be confirmed by the physician, otherwise oesophageal intubation could lead to hypoxia with detrimental consequences and even death. Sonography can be used to determine proper placement of the tracheal tube. Methods: In this study, 75 patients, with an indication of intubation and age older than 18 years entered the study. An emergency medicine performed real-time sonography of the trachea to evaluate the correct placement of endotracheal tube. Tube passage (snowstorm) and vocal cord angel widening (bullet sign) were evaluated, and then both lungs sliding and diaphragm movement were evaluated to confirm correct tube placement and ventilation. Results: In this study, 75 patients entered the study. The mean age of the patients was 61.12; 47 patients (62.7%) were male and 28 (37.3%) were female. The reason of intubation was the decreased level of consciousness in 22 cases (29.3%), cardiopulmonary arrest in 22 patients (29.3%), respiratory distress in 9 patients (12%), shock in 10 patients (13.3%), and seizure in 1 case. Snowstorm sign was seen in 72 patients (96%). Bullet sign was objected in 24 cases (32%). Lung sliding was seen bilaterally in 63 patients (84%) and unilaterally in 7 patients (9.3 %), but it was not noticed in 6.7% of the patients (5 patients). Conclusions: Transverse tracheal and lung sonography in the emergency department can be a fast measure to confirm correct endotracheal intubation.
