Abstract
Securing endotracheal tube (ETT) placement is crucial in anesthesia, with misplacement leading to severe complications. While capnography is considered the gold standard for confirming ETT placement, it has limitations, especially in patients with low pulmonary blood flow or those in cardiac arrest. Transtracheal ultrasound has emerged as an alternative, offering real‐time confirmation without the need for ventilation. This study aimed to compare the efficacy and rapidity of transtracheal ultrasound and capnography in confirming ETT placement in different patient populations, including those with obesity, cardiac arrest and pulmonary diseases. A prospective, investigator‐blinded study was conducted on 144 patients aged 18‐60 years undergoing elective surgeries requiring endotracheal intubation. Patients were divided into groups based on their health conditions (e.g., obesity, cardiac arrest, pulmonary disease). The primary outcome was the time taken to confirm ETT placement using transtracheal ultrasound compared to capnography. Sensitivity and specificity for both methods were also evaluated. Transtracheal ultrasound confirmed ETT placement in 142 out of 144 cases, with a sensitivity of 98.6%. Capnography confirmed placement in all 144 cases, achieving 100% sensitivity. The mean time for transtracheal ultrasound was 15.16 seconds, significantly faster than capnography, which took 23.06 seconds (p<0.001). Both methods demonstrated similar accuracy, but ultrasound was quicker in confirming ETT placement. Transtracheal ultrasound is a highly sensitive and faster alternative to capnography for confirming ETT placement, particularly useful in emergency settings or in patients with conditions that limit the efficacy of capnography. Its real‐time imaging and ability to confirm placement without requiring ventilation make it a valuable adjunct in airway management.
