“…Even in obese patients, ultrasonography with the sliding sign showed higher accuracy than auscultation in confirming tracheal intubation. 14 In the present study, the difference in specificity between novices and experts was smaller when using lung sonography than when using chest auscultation. These findings also support the notion that even novices may easily use lung sonography and achieve relatively accurate results.…”

Objective Lung sonography can be helpful to determine the position of a left-sided double-lumen tube (DLT). However, clinical experience is required for correct assessment. We investigated whether lung sonography can improve the diagnostic efficacy of determining the DLT position in novices and experts. Methods In this randomised prospective clinical study, 88 patients were allocated to two groups using auscultation or lung sonography for initial assessment of the DLT position. In each group, two repeated assessments were performed; the first was performed by a novice, and the second was performed by an expert. The final DLT position was confirmed by fibre-optic bronchoscopy. The primary outcome was the diagnostic efficacy (including overall accuracy, sensitivity, and specificity) in confirming the DLT position. Results In both the novices and experts, the specificity of determining the DLT position was significantly higher with lung sonography than auscultation (60.0% vs. 21.7% and 66.7% vs. 37.5%, respectively). Additionally, the predictability of an incorrect position was similar between the novices and experts using lung sonography (area under the curve of 0.665 and 0.690, respectively). Conclusions Lung sonography can improve the diagnostic efficacy of detecting an incorrect DLT position in both novices and experts.

“…In the management of upper airway, particularly in emergency conditions, the ultrasound has become very important, since it is easily carried out, relatively inexpensive, has a confirmed safety record and does not cause pain [19]. Capnography is not always obtainable in emergency settings and peripheral centers.…”

Background and Aims: In emergency airway management, unstable haemodynamics of the patients calls for the early need to detect correct endotracheal tube (ETT) placement. Ultrasonography has an advantage of being readily available along with being non-invasive and providing real time images. We aimed to study the usefulness of tracheal ultrasonography and use it as a tool to assess correct tracheal intubation in patients in the intensive care unit. Methods: This was a hospital-based observational study. The study included 92 patients who needed and were taken up for endotracheal intubation. Tube placement was confirmed simultaneously by three different observers with their respective method, i.e., ultrasonography, clinical method and capnography. Results: Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ultrasonography against capnography were 100% each with P value of 1. However, for clinical method against capnography, the sensitivity was 96.5%, specificity 28.6%, PPV 94.3% and NPV 40% with P value of 0.727. Mean time taken to detect correct placement of the ETT by ultrasonography, capnography and clinical method was 4.93 s, 15.39s and 17.80s, respectively. Out of 92 intubations, 85 were tracheal and 7 were oesophageal. All intubations were detected accurately with ultrasonography and capnography, ultrasonography being faster. Clinical method correctly detected 82 out of 85 tracheal intubations and 2 out of 7 oesophageal intubations, and was therefore less accurate than the other two methods. Conclusion: The study shows that ultrasonography is as reliable a method for confirmation of endotracheal intubation as capnography and is more reliable than clinical method. Besides, ultrasonography is faster than the other two methods.
