Comparison of clinical, capnography and ultrasonography methods for ETT placement: An observational study.

Accurate confirmation of endotracheal tube (ETT) placement is essential to prevent airway complications. While capnography is the established standard, ultrasonography (USG) offers a rapid, non-invasive alternative. Hence, prospective study of 105 patients was completed. USG and capnography demonstrated excellent diagnostic accuracy, while auscultation showed slightly lower specificity. Therefore it is of interest to report ultrasonography as a faster and effective option for ETT confirmation in critical settings.
