- Abstract
Background and Aims: The most important and lifesaving step of airway management and resuscitation of patients is rapid and accurate endotracheal tube placement. Any delay in confirmation of endotracheal tube placement can lead to potentially life-threatening complications. Capnography, which is considered the gold standard method, also can yield transiently false positive results. We aimed to detect the time taken and to compare the effectiveness of real-time trans-tracheal ultrasonography with waveform capnography to confirm the correct placement of the endotracheal tube. Methods: A prospective observational study was conducted at our tertiary care hospital for a period of six months on 100 patients requiring endotracheal intubation under general anaesthesia. Real-time transtracheal ultrasonography and waveform capnography were used to confirm the correct placement of the endotracheal tube. Time taken by both methods in seconds was noted down by two different observers. Results: The time taken to confirm the correct placement of ETT by ultrasonography was 19.82 ± 5.14s, 95% CI: 18.8 - 20.84 and for capnography was 32.69 ± 5.73s, 95% CI: 31.55 - 33.83, p < 0.001, with a mean difference of 12.87s, 95% CI: 13.61 to 12.069, p < 0.001. The Pearson’s correlation coefficient ‘r value’ was 0.822, 95% CI: 0.746 - 0.877, p < 0.001. The sensitivity, specificity, PPV, and NPV of ultrasonography against capnography were 100%. Conclusion: Transtracheal ultrasonography is a faster, equally accurate and safe technique for confirmation of the correct placement of ETT and can be a good alternative to capnography.
